Gov. Dan McKee is backing off a plan to restrict payments to some of the state’s largest solar farms that he put forward to cut consumers’ energy bills. 
McKee has dropped a proposal for an across-the-board cut to the rate at which so-called virtual net metering projects are paid and is instead putting forward a voluntary fixed-price program that they can choose to opt into.  
Also as part of a budget amendment introduced in the General Assembly April 29, the governor would lower the current cap on virtual net metering projects from 275 megawatts to 125, and move new projects to another state program that pays lower rates.   
The changes would still mean that McKee’s energy relief package would meet its goal of saving ratepayers $1 billion over five years, according to the governor’s office. 
“This proposal protects the projects that are already up and running, aligns our solar program with the region, and gets us one step closer to delivering $1 billion in real relief to the families and businesses who need it most,” McKee said in a statement. 
Net metering is a common program across the country that allows customers to offset their electric bills through credits from renewable energy production. It started out with solar panels or wind turbines installed “behind the meter” at the location where a customer was using power. A home rooftop solar system is an example of a typical project that qualifies for net metering.  
The program was expanded to allow for virtual net metering, with projects at remote locations, so that electric users who didn’t have room on their properties to install solar panels or a wind turbine could switch to renewable energy and qualify for the bill credits. Brown University, the Narragansett Bay Commission, the City of Providence and other big institutional customers have signed on as off-takers of credits for virtual projects.   
But complaints have arisen because net metering pays an inflated rate as an incentive for development. The rate doesn’t just cover the cost of energy. It also repays customers for most distribution costs. While that may make sense for behind-the-meter projects that aren’t as dependent on the distribution system, it’s a stretch for virtual projects, which must still send all of their power out using poles and wires. 
If the projects don’t ease usage of the power grid and their customers aren’t paying their full share of distribution costs, then it means all other ratepayers must pick up the tab. 
Legislators placed restrictions on the virtual program in three years ago, but overall net metering costs have continued to increase, going from $30 million in 2020 to $111 million in 2024, according to the governor’s office. More than 80 % of those costs come from virtual projects. 
As part of his budget plan released in January, McKee proposed forcing virtual off-takers to accept a rate that would be frozen as of July 1. Because energy rates generally go up over time, it would mean that off-takers would see credits go down relative to their bills. 
Solar developers said the move would destroy the industry by compromising existing contracts and undermining confidence in Rhode Island as a place for renewable energy investments.  
The Rhode Island AFL-CIO also came out in opposition to the governor’s proposal, saying that it “would dismantle an industry that is supplying good union jobs.” 
“…many currently operating solar projects would be pushed into structural monthly losses and could be forced to shut down or be decommissioned. This raises the real possibility of dismantling Rhode Island’s existing solar infrastructure and destroying the jobs created through its development,” Erica Hammond, legislative director for the Rhode Island AFL-CIO wrote in testimony when the budget proposal came before the Senate.    
The governor’s new proposal would allow virtual projects to switch to a rate of 19 cents per kilowatt hour that would increase by 2.75% annually for 25 years. 
The starting rate is about equal to the commercial rate virtual net metering projects are currently being paid. 
The governor’s office estimates that doing and lowering the aggregate cap on projects could save ratepayers $25 million a year when compared to projections of increasing costs. The total $1 billion in savings would be felt in a similar way. Costs wouldn’t necessarily go down from where they are now, but they wouldn’t go up as much as projected. The typical ratepayer would be better off by $180 a year, according to administration officials. 
The new budget amendment preserves the other major change to state renewable energy laws proposed by McKee in January: a watering down of the state Renewable Energy Standard, the law that requires annual increases in purchases of renewable energy to offset usage. 
As it’s currently written, the law requires the state to reach 100% renewable purchases by 2033. McKee proposes pushing back that date to 2050, and allowing 25% of purchases to come from nuclear energy and large-scale hydropower.  
Environmental advocates have called the weakening of the law short-sighted, saying that the administration is only looking at one side of the ledger and hasn’t factored in the benefits of renewables, not only to the climate and public health but also to customer bills by reducing the region’s overdependence on natural gas.

French solar module recycling company ROSI has announced plans to open a new facility in Spain.
The new site in Turuel, north of Valencia, will be able to process 10,000 tonnes of solar PV materials annually, ROSI claimed. The company said it would reclaim valuable materials like silver, copper and aluminium, as well as silicon and glass, from disused solar modules and aim to feed them back into the supply chain.

The company announced a €20 million (US$23.5 million) investment to support the new facility, led by InnoEnergy, CMA CGM, the European Innovation Council (EIC) and Spanish family office G3T.
President and co-founder of ROSI, Yun Luo, said the financing was an “important milestone” for the company. “It gives us the means to accelerate our industrial deployment, strengthen our operational execution, and prepare for a new phase of growth in Europe.
“Our ambition is to build a European-scale industrial platform for circular management and the production of strategic raw materials, transforming end-of-life solar panels into a reliable source of high-purity materials for the European industries of tomorrow.”
The new facility builds on ROSI’s existing ROSI Alpes plant in France. Along with the announcement of the new facility and financing, the company has appointed a new director in France, Thierry Galvez, who entered the role on 1 April.
ROSI claimed that the expansion of its operations to Spain enables “scalable circular model for photovoltaic recycling in Europe”. Gianmarco Panone, investment manager at InnoEnergy, said ROSI is “one of the most emblematic photovoltaic assets in our portfolio” due to its “differentiated technology.”
On its website, ROSI claims that its technology can “properly separate” the materials and layers in a PV module, allowing them to be recovered individually, and therefore more purely. It also says it has technology to recycle kerf, the wasted silicon powder produced when cutting silicon wafers.
There are other companies around the world offering solar recycling, such as PV Cycle and Solar Materials in Europe.
In the US, Solarcycle has established a dedicated recycling operation alongside plans for a factory producing new solar glass from recycled products. Comstock Inc. is also pursuing solar recycling in Nevada. Australia has also launched PV recycling operations to deal with panels at the end of their lives.
However, a study published last month found that the European solar sector needs “urgent” reform of its solar PV recycling, as the capacity to deal with disused modules lags significantly behind projected PV deployment rates. The study found that even though solar modules are included under the EU’s Waste Electrical and Electronic Equipment (WEEE) Directive, implementation is patchy across member states.

As global energy needs intensify and the search for sustainable solutions accelerates, organic solar cells (OSCs) have rapidly positioned themselves as a leading contender in the race for next-generation photovoltaic technologies. Their inherent advantages—lightweight construction, mechanical flexibility, and ease of large-area solution processing—make them uniquely suited for diverse applications beyond the limitations of traditional inorganic devices. Among the myriad of design architectures explored to enhance OSC performance, pseudo-planar heterojunction (PPHJ) structures have gained significant traction due to their balanced attributes of efficiency and stability. These architectures rely heavily on layer-by-layer deposition techniques that enable precise control over vertical phase separation—a pivotal factor in optimizing charge generation and transport.
Despite the promising potential of the layer-by-layer approach, challenges persist. Foremost among these is the inadvertent solvent-induced damage that occurs during the sequential deposition of the active layers. Typically, when the acceptor layer is applied, the solvents used can swell or erode the underlying donor layer. This leads to undesirable mixing of the donor and acceptor materials, disrupting the carefully engineered vertical phase separation. The compromised interface hastens charge recombination, impairs transport, and ultimately diminishes device efficiency.
In a groundbreaking study published in the Chinese Journal of Polymer Science, researchers presented a pioneering interfacial buffering methodology aimed specifically at eradicating solvent erosion issues endemic to PPHJ fabrication. The crux of their strategy involves the incorporation of a highly crystalline polymer donor, designated D18, as a buffer layer interposed between the conventional donor and acceptor strata. This architectural refinement successfully instills robust resistance against solvent-induced infiltration, thereby preserving the active layer’s morphology and optimizing its functional architecture.
The use of D18, distinguished by its high crystallinity, engenders a densely packed fibrillar network that physically obstructs solvent permeation during the acceptor’s deposition phase. This network acts as a formidable barrier, maintaining the structural and chemical integrity of the donor layer beneath. Such a preservation of morphology is crucial because a well-defined heterojunction interface is instrumental in facilitating efficient exciton dissociation and charge separation processes.
Furthermore, the enhanced molecular arrangement achievable with the buffer layer profoundly influences the vertical phase separation within the solar cell’s active region. Instead of the blurred, interpenetrated morphologies typical of solvent-affected systems, this buffered configuration promotes a sharply segregated gradient between donor and acceptor domains. This distinct phase purity fosters the establishment of uninterrupted charge transport channels. As a result, charge carriers encounter fewer trapping sites, leading to reduced non-radiative recombination losses and improved photovoltaic outputs.
Quantitatively, the integration of the interfacial buffer layer translated into a leap in power conversion efficiency (PCE). Devices leveraging this buffer achieved an efficiency of 19.80%, already surpassing many contemporaneous binary systems. Intriguingly, the research team further refined device architecture by introducing a ternary component, which enhanced light absorption capabilities. This adjustment pushed the efficiency even higher, to an impressive 20.21%. This metric situates these PPHJ organic solar cells among the most efficient reported to date, underscoring the viability of the buffering strategy.
Beyond the immediate performance enhancements, this study holds broader scientific and technological significance. It elucidates how interface engineering, especially at the nanoscale level, governs morphology evolution during multi-layer solution processing. The dual functions of physical solvent barrier and microstructural regulation manifest synergistically within the crystalline buffer layer. Such insights pave the way for scalable manufacturing processes that maintain device integrity while reducing fabrication-induced defects.
From a materials science perspective, this approach illuminates new avenues for morphological control in thin-film photovoltaic devices. The crystalline polymer buffer layer mediated solvent interactions without compromising the chemical or electronic properties of the constituent materials. This finding is vital for advancing flexible and solution-processable solar energy technologies, where solvent compatibility has long represented a critical bottleneck.
Moreover, the implications extend to the future of sustainable energy deployment. OSCs equipped with such interfacial engineering techniques could be integrated into a variety of form factors, including wearable electronics, building-integrated photovoltaics, and portable power sources. The discovered methodology holds promise for improving not only laboratory-scale devices but also the manufacturing of high-efficiency OSC modules on an industrial scale.
In conclusion, the interfacial buffering innovation marks a significant leap forward in organic solar cell technology. By marrying a highly crystalline polymer buffer within the PPHJ architecture, researchers have surmounted persistent challenges associated with solvent erosion and morphological degradation. The success achieved in preserving optimal phase separation and enhancing charge transport culminates in record-high efficiencies that herald a new era for organic photovoltaics. This work not only sets a new performance benchmark but also provides valuable design principles to guide the next generation of flexible, scalable, and ultra-efficient solar energy solutions.

THE church is looking to go a little greener as plans are submitted to erect solar panels around Winchester Cathedral.
The cathedral has applied to erect the solar panels on the roofs of five non-listed buildings within the cathedral estate.
This includes at The Works Yard, the Works Yard garage block, the Wessex Learning Centre, The Refectory and The Paul Woodhouse Suite.
The design and access statement, put together by T2 Architects, says: “The locations selected for the installation of photovoltaic panels are on non-listed buildings and on roofs which are easily accessible, yet not highly visible within the public realm.
“The aim of the application is to reduce the Cathedral Estate’s usage of fossil fuels and to improve the Estate’s environmental performance by using renewable energy. The Church Of England has set a target to be net carbon zero by 2030. Winchester Cathedral is targeting a carbon reduction carbon of 6 per cent, year on year.
“Winchester Cathedral is currently accredited as Eco Church ‘silver’, and is working towards achieving ‘gold’.”

WCC’s Historic Environment team have been consulted on the plans, saying: “This is a substantial application which proposes to install solar panels on no less than 5 separate buildings, all of which happen to be within the Winchester Cathedral Estate. None are historic buildings, the oldest being circa 1970. The roof slopes subject to this application have been carefully chosen to avoid prominence within the conservation area, and principal views of listed buildings. The Council is pleased to support the custodians of historic buildings in making their properties more energy efficient, and this scheme fits well with this ambition.
“The proposals will preserve the significance of the heritage assets listed above, and would support the Cathedral in powering (and maintaining) its plethora of historic buildings. There are no concerns with this application in heritage terms.”
One letter of support has been received by the council in regards to the application.
Christine Holloway, of St Swithun Street, said: “I am very pleased to support the Cathedral in making its properties less reliant on fossil fuels, and hope to see more in future.”

The Indonesia Solar Component Cleaning Chemicals market encompasses specialty chemical products used to remove soiling, dust, bird droppings, cement residue, pollen, and industrial pollutants from photovoltaic modules, mounting structures, and associated solar components. These chemicals are essential for maintaining energy yield, particularly in Indonesia’s tropical climate where soiling losses can reach 15–25% per month in dry-season, high-dust environments. The market sits at the intersection of the renewable energy operations and maintenance (O&M) ecosystem and the specialty chemical industry, with strong linkages to water treatment, surfactant chemistry, and surface coating technology.
Indonesia’s solar PV installed capacity is expected to grow from approximately 0.5 GW in 2025 to over 10 GW by 2035, driven by the government’s target of 23% renewable energy in the primary energy mix by 2025 and the development of large-scale solar parks under the PLN electricity procurement plan. This capacity expansion directly drives demand for cleaning chemicals, as every MW of utility-scale solar requires 4–8 cleaning cycles per year depending on location, soiling intensity, and rainfall patterns. The market is characterized by a mix of global specialty chemical conglomerates, regional formulators, and local distributors, with import dependence dominating the supply chain.
The product portfolio includes concentrated liquid detergents (the largest segment by volume), ready-to-use solutions, deionized water rinse additives, anti-reflective and hydrophobic coatings, and heavy deposit removers for cement, lime, and industrial grime. Application segments span utility-scale solar farms, commercial and industrial rooftops, residential PV systems, floating solar installations, and agrivoltaic projects. The value chain involves formulators and branded chemical suppliers, O&M service providers who integrate chemicals with cleaning services, distributors and wholesalers, and EPC firms that specify chemicals for new project handover packages.
The Indonesia Solar Component Cleaning Chemicals market is estimated at approximately IDR 180–240 billion (USD 11–15 million) in 2026, based on volume of 2,500–3,200 kiloliters and blended average pricing of IDR 70,000–75,000 per liter. This market size reflects only dedicated solar cleaning chemical products and excludes general-purpose detergents, water-only cleaning, and unverified generic formulations used informally in the residential segment. The market is expected to grow at a compound annual growth rate (CAGR) of 12–15% from 2026 to 2035, reaching IDR 550–850 billion (USD 34–52 million) by 2035, driven by accelerating solar capacity additions, increasing cleaning frequency requirements, and premium product adoption.
Volume growth is closely correlated with Indonesia’s solar PV installed base expansion. Each additional GW of utility-scale solar capacity generates demand for approximately 400–600 kiloliters of cleaning chemicals annually, assuming 6–8 cleaning cycles per year and average chemical consumption of 70–100 liters per MW per cycle. The forecast period 2026–2035 includes a significant inflection point around 2028–2030, when several large-scale solar parks (100–500 MW each) in East Java, South Sumatra, and Kalimantan are expected to reach peak O&M intensity, driving a step-change in chemical procurement volumes.
By value, the market is growing faster than volume due to a shift toward higher-priced specialty products. Anti-soiling coatings, which carry 2–3x the per-liter price of standard detergents, are projected to grow from 8–10% of market value in 2026 to 18–22% by 2035. Similarly, ready-to-use solutions, which command a premium over concentrates due to convenience and reduced on-site mixing requirements, are gaining share in the commercial and residential segments.
By product type, concentrated liquid detergents dominate the Indonesia market with 55–60% volume share in 2026, favored by utility-scale O&M providers for their lower shipping weight, longer shelf life, and cost-effective dilution ratios. Ready-to-use solutions account for 20–25% of volume, primarily in commercial rooftop and residential applications where on-site mixing is impractical. Deionized water rinse additives represent 5–8% of volume, used in conjunction with deionized water systems to prevent mineral spotting on modules. Anti-reflective and hydrophobic coatings, while small in volume (3–5%), command high value due to their premium pricing and application as a protective layer rather than a consumable. Heavy deposit removers account for 5–7% of volume, used for corrective cleaning after construction, dust storms, or industrial pollution events.
By application, utility-scale solar farm cleaning is the dominant end-use, accounting for 65–70% of chemical demand in 2026. Indonesia’s utility-scale solar pipeline includes projects in the 50–500 MW range, with major clusters in East Java (Gresik, Tuban), South Sumatra (Ogan Komering Ilir), West Java (Cirata floating solar expansion), and Kalimantan. Commercial and industrial rooftop cleaning represents 15–20% of demand, driven by factory rooftops in industrial estates near Jakarta, Surabaya, and Batam. Residential PV cleaning accounts for 5–8%, with growth constrained by price sensitivity and the prevalence of informal cleaning practices. Floating solar PV cleaning, while nascent at 2–3% of demand, is a high-growth niche, particularly at the 145 MW Cirata floating solar plant and planned projects on Sumatra’s Lake Singkarak and Kalimantan’s artificial reservoirs. Agricultural PV (agrivoltaics) cleaning is emerging in Java’s agricultural regions, where combined crop and solar operations require specialized chemical formulations that are safe for nearby crops and soil.
By end-use sector, utility-scale solar independent power producers (IPPs) are the largest buyer group, procuring chemicals through O&M service providers or directly for self-operated plants. Commercial and industrial facility owners represent the second-largest group, often purchasing through distributors or bundled cleaning service contracts. Residential solar asset owners are a fragmented, price-sensitive segment, while public sector and community solar projects are small but growing, with procurement often tied to government tenders that specify environmentally certified products.
Pricing in the Indonesia Solar Component Cleaning Chemicals market varies significantly by product type, formulation complexity, packaging, and distribution channel. Concentrated liquid detergents are priced at IDR 45,000–85,000 per liter (USD 2.80–5.30), with bulk purchases (200-liter drums or IBC totes) at the lower end and specialty formulations for heavy soiling at the upper end. Ready-to-use solutions command IDR 80,000–140,000 per liter, reflecting the convenience premium and lower dilution requirements. Deionized water rinse additives are priced at IDR 60,000–100,000 per liter, while anti-reflective and hydrophobic coatings range from IDR 120,000 to 200,000 per liter, driven by proprietary chemistry and performance guarantees. Heavy deposit removers are priced at IDR 70,000–120,000 per liter, with higher prices for formulations that are safe for glass and aluminum frames.
Cost per cleaning cycle is the most relevant pricing metric for O&M providers. A typical utility-scale cleaning cycle using concentrated detergent at 1:100 dilution costs IDR 400,000–700,000 per MW (USD 25–43), including chemical, labor, water, and equipment costs. For a 100 MW solar farm with 6 cycles per year, annual chemical costs range from IDR 240–420 million (USD 15,000–26,000), representing 8–12% of total O&M expenditure. Total cost of ownership per MW per year, including chemical, labor, water, and equipment amortization, ranges from IDR 2.5–4.5 million (USD 155–280), with chemical costs constituting 15–20% of the total.
Key cost drivers include raw material prices for surfactants, wetting agents, and chelating agents, which are imported and subject to global petrochemical price fluctuations. Logistics costs for inter-island shipping add 15–25% to landed costs for deliveries outside Java. Import duties on specialty chemicals under HS codes 340290, 380991, and 381590 are typically 5–10%, though tariff treatment depends on origin, product code, and trade agreements. Currency exchange rate volatility between the Indonesian rupiah and the US dollar directly impacts import costs, as most specialty chemicals are priced in USD. Regional price premiums exist for harsh environment formulations, with products designed for cement-dust-prone areas or coastal saline environments commanding 20–30% premiums over standard formulations.
The Indonesia Solar Component Cleaning Chemicals market features a mix of global specialty chemical conglomerates, dedicated solar O&M chemical formulators, regional chemical distributors with solar verticals, and water treatment companies extending into solar cleaning. The competitive landscape is moderately concentrated, with the top 5–6 suppliers accounting for 55–65% of market revenue in 2026, while numerous smaller distributors and local formulators serve niche segments.
Global specialty chemical conglomerates such as BASF, Dow, and Clariant participate through regional distributors and direct supply agreements, offering branded surfactant blends, wetting agents, and anti-soiling coating technologies. These companies leverage global R&D capabilities and established supply chains but face challenges in adapting formulations to Indonesia’s tropical conditions and navigating local regulatory requirements. Dedicated solar O&M chemical formulators, including companies like SolarCleano, Ecoppia (through chemical partnerships), and regional players such as CleanSolar Asia, offer integrated chemical solutions tailored to specific soiling conditions and cleaning equipment compatibility. These formulators often provide technical support, on-site training, and performance guarantees, commanding premium pricing.
Regional chemical distributors with solar verticals, such as PT Multi Kimia Inti, PT Sigma Utama, and PT Bumiraya Kimia, import bulk chemicals from Singapore, Malaysia, and China, repackage for the Indonesian market, and distribute through local dealer networks. These distributors are critical for reaching the fragmented C&I and residential segments, offering competitive pricing and shorter lead times. Water treatment companies, including PT Aqua Kimia and PT Tirta Kencana, have extended their product lines to include deionized water systems and rinse additives for solar cleaning, leveraging existing customer relationships with industrial facilities that have rooftop solar installations.
Competition is intensifying as the market grows, with new entrants from China and South Korea offering lower-priced formulations that undercut established global brands by 15–25%. However, quality concerns and lack of local certification limit the penetration of these low-cost products in the utility-scale segment, where asset owners prioritize performance guarantees and compatibility with module warranties. Brand reputation, technical support, and supply reliability are key differentiators, particularly for long-term O&M contracts.
Indonesia has limited domestic production capacity for dedicated solar component cleaning chemicals, with local manufacturing primarily limited to blending, dilution, and repackaging of imported raw materials. The country’s specialty chemical industry is concentrated in Java, particularly in the industrial estates of Cilegon (Banten), Cikarang (West Java), and Gresik (East Java), where several chemical blending plants operate. These facilities primarily produce general-purpose industrial cleaners, detergents, and water treatment chemicals, with solar-specific formulations representing a small fraction of output.
Domestic production of solar cleaning chemicals is constrained by several factors. First, the formulation expertise required for products that are safe for PV module glass, anti-reflective coatings, and aluminum frames is specialized and largely held by global chemical companies or their licensed partners. Second, high-purity raw materials, including specialty surfactants, chelating agents, and biodegradable solvents, are not produced domestically in sufficient quantities or grades, requiring imports from China, South Korea, Germany, and the United States. Third, the relatively small market size (compared to general industrial cleaners) limits the economic viability of dedicated local production lines.
Several Indonesian chemical companies are exploring local formulation capabilities, driven by government incentives for domestic manufacturing and the growing demand from the solar sector. PT Multi Kimia Inti has invested in a dedicated solar cleaning chemical blending line in Cikarang, targeting the utility-scale segment with locally branded products. PT Sigma Utama has partnered with a Malaysian formulator to produce ready-to-use solutions under license, reducing import dependence for that product category. However, these initiatives remain nascent, and import dependence is expected to persist at 70–80% of volume through 2030, gradually declining to 60–70% by 2035 as local formulation capacity expands.
Indonesia is a net importer of solar component cleaning chemicals, with imports accounting for 70–80% of domestic consumption in 2026. The primary import sources are Singapore (25–30% of import volume), Malaysia (20–25%), China (18–22%), and South Korea (10–15%), with smaller volumes from Germany, Japan, and the United States. Singapore and Malaysia serve as regional distribution hubs, where global chemical companies maintain blending and warehousing facilities that supply the Southeast Asian market. China and South Korea supply cost-competitive bulk formulations, particularly concentrated detergents and heavy deposit removers.
Imports enter Indonesia through major ports including Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), Belawan (Medan), and Makassar, with customs clearance under HS codes 340290 (surface-active preparations, washing and cleaning preparations), 380991 (finishing agents, dye carriers, and other auxiliary products for the textile and like industries, used in solar cleaning as wetting agents), and 381590 (reaction initiators, reaction accelerators, and catalytic preparations, applicable to some anti-soiling coating formulations). Import duties range from 5–10% ad valorem, with additional value-added tax (PPN) of 11% and income tax (PPh) of 2.5–7.5% on imports, depending on the importer’s status and product classification.
Trade flows are influenced by regional supply chain dynamics. Singapore’s role as a regional chemical hub means that many global brands supply the Indonesian market through Singapore-based distributors, adding 5–10% to costs compared to direct imports from China or South Korea but offering shorter lead times and better quality assurance. Malaysia’s proximity to Sumatra and Kalimantan makes it a cost-effective source for bulk shipments to western and central Indonesia. Exports of solar cleaning chemicals from Indonesia are negligible, as domestic production is insufficient to meet local demand, and the country lacks the scale and formulation expertise to compete in export markets.
Tariff treatment depends on origin, product code, and trade agreements. Under the ASEAN Trade in Goods Agreement (ATIGA), imports from Singapore and Malaysia may qualify for preferential duty rates of 0–5%, provided the products meet ASEAN content requirements. Imports from China may benefit from the ASEAN-China Free Trade Area (ACFTA) tariff preferences, though rules of origin and product-specific exclusions apply. Importers typically work with licensed customs brokers to navigate these trade agreements and minimize duty costs.
Distribution of solar component cleaning chemicals in Indonesia follows a multi-tier structure, with distinct channels serving different buyer segments. The primary distribution channels include direct sales from formulators to large O&M service providers, distributor networks serving commercial and residential segments, and integrated chemical-plus-service offerings from O&M companies.
Direct sales account for 35–40% of market volume, primarily serving utility-scale solar farm operators and large O&M service providers. Global formulators and regional distributors maintain dedicated sales teams that negotiate annual supply contracts, often with volume commitments, pricing tiers, and technical support agreements. These contracts typically specify chemical specifications, dilution ratios, packaging requirements, and delivery schedules, with pricing fixed or indexed to raw material costs. Direct sales are concentrated in Java, where the majority of utility-scale solar farms are located.
Distributor networks serve the commercial and industrial rooftop segment, as well as smaller O&M providers and residential installers. Regional distributors such as PT Multi Kimia Inti, PT Sigma Utama, and PT Bumiraya Kimia maintain warehouse networks in Java, Sumatra, and Sulawesi, supplying local dealers and solar equipment wholesalers. These distributors typically stock concentrated detergents and ready-to-use solutions in 20-liter pails and 200-liter drums, offering same-day or next-day delivery in urban areas. Distributor margins range from 15–25%, depending on volume and product complexity.
Integrated chemical-plus-service offerings are growing in importance, with O&M service providers bundling chemicals with cleaning labor, equipment, and water supply. Companies such as PT Solar O&M Indonesia, PT Energi Bersih, and regional service providers offer cleaning contracts that include chemical costs within a per-MW-per-cycle fee, simplifying procurement for asset owners. This channel accounts for 25–30% of chemical consumption, as asset owners increasingly prefer single-vendor O&M solutions.
Buyer groups include solar O&M service providers (primary buyers, accounting for 50–60% of procurement decisions), asset owners and operators who procure directly for self-operated plants (20–25%), EPC firms that specify chemicals for new project handover packages (10–15%), and distributors and solar wholesalers serving the commercial and residential segments (10–15%). Procurement decisions are influenced by chemical performance, compatibility with module warranties, price, supplier reliability, and environmental certifications.
How commercial burden rises from technical fit toward approved deployment, bankability, and lifecycle support.
The regulatory landscape for solar component cleaning chemicals in Indonesia is evolving, with multiple frameworks governing chemical composition, environmental impact, worker safety, and product certification. The primary regulatory bodies include the Ministry of Environment and Forestry (KLHK) for wastewater discharge and biodegradability standards, the Ministry of Industry for chemical product registration and labeling, and the National Agency for Drug and Food Control (BPOM) for products that may come into contact with water sources used for human consumption.
Chemical registration and labeling requirements under Government Regulation No. 74/2001 on Hazardous Substances Management require importers and domestic producers to register hazardous chemical products with the Ministry of Industry. Solar cleaning chemicals that contain surfactants, solvents, or acids above specified concentration thresholds are classified as hazardous and require Material Safety Data Sheets (MSDS) in Indonesian, proper labeling, and storage documentation. Registration timelines range from 2–6 months, depending on the product’s hazard classification and the availability of supporting documentation.
Wastewater discharge regulations vary by province, with Java’s more industrialized regions (West Java, East Java, Banten) enforcing stricter limits on chemical oxygen demand (COD), biochemical oxygen demand (BOD), pH, and surfactant concentrations in wastewater discharged from solar cleaning operations. In agricultural and residential areas, additional restrictions apply to ensure that cleaning runoff does not contaminate irrigation water or groundwater. O&M providers must obtain wastewater discharge permits for large-scale cleaning operations, with compliance costs adding 5–10% to cleaning cycle costs.
Biodegradability and toxicity certifications are increasingly important for market access, particularly for utility-scale projects financed by international development banks or subject to environmental, social, and governance (ESG) criteria. International certifications such as EPA Safer Choice (US), EU Ecolabel, and OECD biodegradability testing are recognized by Indonesian asset owners, though local certification pathways are limited. Several Indonesian O&M providers require suppliers to provide third-party test reports for acute toxicity, aquatic toxicity, and biodegradability, with preference for products that achieve >60% biodegradation within 28 days.
Agricultural land use restrictions are relevant for agrivoltaic projects and solar farms located near agricultural areas. Local regulations in some regencies restrict the use of certain surfactants and solvents that may affect soil quality or crop growth. Suppliers targeting the agrivoltaic segment must provide formulations that are certified as safe for agricultural use, with additional testing for phytotoxicity and soil microbial impact.
The Indonesia Solar Component Cleaning Chemicals market is forecast to grow from IDR 180–240 billion (USD 11–15 million) in 2026 to IDR 550–850 billion (USD 34–52 million) by 2035, representing a CAGR of 12–15%. Volume is projected to increase from 2,500–3,200 kiloliters to 7,500–11,000 kiloliters over the same period, driven by the expansion of Indonesia’s solar PV installed base from approximately 2 GW in 2026 to 10–15 GW by 2035.
Key forecast assumptions include: Indonesia’s solar PV capacity additions of 1.0–1.5 GW per year from 2026–2030, accelerating to 1.5–2.5 GW per year from 2031–2035; average cleaning frequency of 6–8 cycles per year for utility-scale farms, declining to 4–6 cycles for residential systems; chemical consumption of 70–100 liters per MW per cycle for utility-scale, with higher consumption for floating solar due to biofilm and algae growth; and average price growth of 2–4% per year, driven by premium product adoption and raw material cost inflation.
Segment-level forecasts indicate that concentrated liquid detergents will maintain volume leadership but decline in share from 55–60% in 2026 to 45–50% by 2035, as ready-to-use solutions and anti-soiling coatings gain ground. Ready-to-use solutions are projected to grow at 14–16% CAGR, reaching 25–30% of volume by 2035, driven by commercial and residential segment growth. Anti-soiling coatings, while small in volume, are forecast to grow at 18–22% CAGR in value terms, reaching 18–22% of market value by 2035. Heavy deposit removers will grow in line with construction activity for new solar farms, with periodic spikes during post-construction cleaning phases.
Application-level forecasts show utility-scale solar remaining dominant at 60–65% of volume through 2035, with floating solar PV cleaning growing from 2–3% to 8–12% of volume, reflecting the government’s focus on floating solar development on reservoirs and lakes. Commercial and industrial rooftop cleaning will grow at 10–12% CAGR, while residential cleaning remains a small but steady segment at 5–7% of volume.
Supply-side forecasts project a gradual reduction in import dependence from 70–80% in 2026 to 60–70% by 2035, as local formulation capacity expands and government incentives for domestic manufacturing take effect. However, high-purity raw materials and specialty formulations will continue to be imported, maintaining a structural trade deficit in this product category.
Floating solar PV cleaning chemistry specialization: Indonesia’s floating solar pipeline, including the expansion of Cirata and new projects on Sumatra and Kalimantan, creates demand for cleaning chemicals that address biofilm, algae, and mineral scaling unique to freshwater environments. Suppliers that develop formulations specifically for floating solar, with anti-algal properties and low aquatic toxicity, can capture a first-mover advantage in this high-growth niche.
Waterless and low-water chemistry innovation: Water scarcity in eastern Indonesia and parts of Java presents a significant opportunity for waterless cleaning solutions and low-water chemistries that reduce per-cycle water consumption by 60–80%. Products that combine electrostatic cleaning, dry surfactants, or vapor-phase cleaning agents can command premium pricing and long-term contracts with O&M providers operating in water-constrained regions.
Local formulation and blending partnerships: The Indonesian government’s push for domestic manufacturing, combined with growing market scale, creates opportunities for joint ventures between global chemical companies and local Indonesian firms to establish local blending and formulation facilities. Such partnerships can reduce import dependence, lower logistics costs, and improve supply chain resilience, while qualifying for government procurement preferences.
Certification and testing service development: The lack of local certification and testing infrastructure for solar cleaning chemicals represents a bottleneck that also creates an opportunity. Companies that establish Indonesian laboratories for biodegradability testing, toxicity assessment, and PV module compatibility testing can serve both chemical suppliers and O&M providers, accelerating product registration and market access.
Performance-based chemical contracting models: Asset owners’ increasing focus on energy yield recovery and LCOE optimization creates an opportunity for chemical suppliers to offer performance-based pricing, where chemical costs are linked to measured soiling loss reduction or yield improvement. Suppliers with strong data analytics capabilities and proven formulation performance can differentiate themselves and secure long-term, higher-margin contracts with utility-scale IPPs.
Agrivoltaic cleaning chemistry: Indonesia’s growing interest in agrivoltaics, particularly in Java’s agricultural regions, creates demand for cleaning chemicals that are safe for crops, soil, and irrigation water. Formulations that meet agricultural chemical restrictions while effectively cleaning PV modules in dusty, humid agricultural environments represent a specialized opportunity with limited competition.

At its core, this report explains how the market for Solar Component Cleaning Chemicals actually functions. It identifies where demand originates, how supply is organized, which technological and regulatory barriers influence adoption, and how value is distributed across the value chain. Rather than describing the market only in broad terms, the study breaks it into analytically meaningful layers: product scope, segmentation, end uses, customer types, production economics, outsourcing structure, country roles, and company archetypes.
The report is particularly useful in markets where buyers are highly specialized, suppliers differ significantly in technical depth and regulatory readiness, and the commercial landscape cannot be understood only through top-line market size figures. In this context, the study is designed not only to estimate the size of the market, but to explain why the market has that size, what drives its growth, which subsegments are the most attractive, and what it takes to compete successfully within it.
The report is based on an independent analytical methodology that combines deep secondary research, structured evidence review, market reconstruction, and multi-level triangulation. The methodology is designed to support products for which there is no single clean official dataset capturing the full market in a directly usable form.
The study typically uses the following evidence hierarchy:
The analytical framework is built around several linked layers.
First, a scope model defines what is included in the market and what is excluded, ensuring that adjacent products, downstream finished goods, unrelated instruments, or broader chemical categories do not distort the market boundary.
Second, a demand model reconstructs the market from the perspective of consuming sectors, workflow stages, and applications. Depending on the product, this may include Preventive soiling loss mitigation, Corrective cleaning after dust storms or pollution events, Performance recovery for underperforming assets, Pre-commissioning cleaning of new installations, and Maintenance prior to peak generation seasons across Utility-Scale Solar Independent Power Producers (IPPs), Commercial & Industrial (C&I) Facility Owners, Residential Solar Asset Owners, and Public Sector & Community Solar Projects and O&M Planning & Budgeting, Chemical Specification & Procurement, Field Service Execution, and Performance Validation & Reporting. Demand is then allocated across end users, development stages, and geographic markets.
Third, a supply model evaluates how the market is served. This includes Specialty surfactants, Corrosion inhibitors, pH stabilizers, Deionized water, Biodegradable solvents, and Packaging (containers, totes), manufacturing technologies such as Surfactant & wetting agent chemistry, Water softening & deionization technology, Automated cleaning robot compatibility, Spray-and-rinse vs. waterless application methods, and Long-lasting hydrophobic/oleophobic coating tech, quality control requirements, outsourcing, contract manufacturing, integration, and project-delivery participation, distribution structure, and supply-chain concentration risks.
Fourth, a country capability model maps where the market is consumed, where production is materially feasible, where manufacturing capability is limited or emerging, and which countries function primarily as innovation hubs, supply nodes, demand centers, or import-reliant markets.
Fifth, a pricing and economics layer evaluates price corridors, cost drivers, complexity premiums, outsourcing logic, margin structure, and switching barriers. This is especially relevant in markets where product grade, purity, customization, regulatory burden, or service model materially influence economics.
Finally, a competitive intelligence layer profiles the leading company types active in the market and explains how strategic roles differ across upstream material suppliers, component and controls providers, OEMs, storage-system integrators, EPC partners, project developers, and distribution or service channels.

CHRISTIANA, Tenn. — A Tennessee solar developer is betting that cattle-grazing and solar panels can coexist — and benefit farmers as well as the electric grid.
From a distance, the small solar farm in central Tennessee looks like others that now dot rural America, with row upon row of black panels absorbing the sun's rays to generate electricity.
But beneath these panels is lush pasture instead of gravel, enjoyed by a small herd of cattle that spends its days munching grass and resting in the shade.
Silicon Ranch, which owns the 40-acre farm in Christiana, outside of Nashville, believes cattle-grazing is the next frontier in so-called agrivoltaics, which mostly has involved growing crops or grazing sheep beneath the panels.
The solar company debuted the project this week and will spend the next year working to demonstrate to farmers that much larger cattle also can thrive at solar sites. If successful, advocates say, that could jump-start new projects to meet the soaring electricity demand driven by rapidly expanding data centers — without contributing climate-warming carbon emissions — and help cattle producers hold onto their land and livelihoods.
“Solar is one of the most powerful tools we have for cutting emissions and … is cost-competitive with fossil fuels,” said Taylor Bacon, a doctoral student at Colorado State University who has studied ecological outcomes at solar grazing sites. “I think we’re starting to see enough research that, when you do it well, the land use can be more of an opportunity than a downside."
Making room for cattle
Though there are far more cattle than sheep in the U.S., their size poses challenges at solar sites, where both expensive equipment and the animals, which can weigh more than half a ton, must be protected.
Solar panels often pivot to near-vertical angles to capture the sun’s rays, leaving little room underneath for cattle; simply raising the panels is cost-prohibitive because of the amount of steel required. So Silicon Ranch raised the panels a little but also developed software that workers activate to turn the panels close to horizontal when cattle are grazing, giving them room to wander, said Nick de Vries, the company's chief technology officer.
Workers rotate the cattle — currently 10 cows and their calves — between paddocks every few days so panels on the ungrazed portion of the site operate normally, generating a supply of roughly 5 megawatts of electricity for Middle Tennessee Electric, a rural electric co-op.
The hope is that the technology eventually will be adopted more broadly, company officials said.
“We know it works," said de Vries. "But you need to prove it to other people."
What are the benefits for farmers?
For solar companies, agricultural land is generally easier to develop than other types of sites. But many farmers — and communities — will need to be convinced that solar grazing will benefit them because of past practices that destroyed topsoil and took land out of production permanently.
"For many agricultural stakeholders, it is offensive to see high-quality farmland getting graded and piled when that’s a farm family’s legacy,” said Ethan Winter, national smart solar director at American Farmland Trust.
But he sees potential for solar grazing partnerships to help farmers keep their land in production and earn extra income at a time when it's increasingly difficult to earn money farming and ranching alone.
“Agriculture is in a really tough spot right now" including because of trade wars, climate extremes, increased costs and pressure to sell, Winter said. "So maybe this is our moment where we can be helping states meet their energy needs and do that in a way that’s providing new opportunities for farmers.”
Silicon Ranch this year will have almost 15,000 acres of pasture being grazed — mostly by sheep — since launching five years ago, and is working with ranchers, farmers, university researchers and others to adopt best-practices for keeping soils and animals healthy.
What they're finding is that pasture beneath solar panels retains more moisture, making it more drought tolerant, said Anna Clare Monlezun, a rancher and rangeland ecosystem scientist who's working on the Tennessee project. Grazing in the shade leaves animals less prone to heat stress, enabling them to gain more weight and drink less water.
“There are more win-wins than trade-offs,” she said.
Sheep already have proven to be a good fit for solar sites, with more than 130,000 acres grazed as of 2024, a number that certainly has grown, said Kevin Richardson, senior director of the American Solar Grazing Association.
But for cattle, the industry still has to overcome site-design challenges and be able to scale up operations while also developing appropriate economic incentives for ranchers, Richardson said.
“Once we have that, I think we’ll see more solar sites using cattle or multi-species grazing with sheep and cattle,” he said.
Farmers often earn about $1,000 an acre by leasing their land for solar, easily 10 times more than what they historically earned through traditional agriculture, said Winter, from the Farmland Trust. That can help them to diversify operations, pay down debt and buy more land.
“I think you’ll start to hear more interest from farmers who are up against a serious financial wall right now and looking for income diversification opportunities that keep land in production,” Winter said. “We need and want to grow America’s energy capacity but not at the expense of our best farmland or at the expense of agricultural livelihoods.”

In Q1 2026, grid-scale solar generation jumped 648 MW compared to the same period in 2025, recording an all-time quarterly high of 2,706 MW output, according to new figures released by AEMO in its Quarterly Energy Dynamics Q1 2026 report.
Image: European Energy
Grid-scale solar recorded an all-time quarterly high of 2,706 MW, up 648 MW year-on-year, according to new figures released by the Australian Energy Market Operator (AEMO) in its Quarterly Energy Dynamics (QED) Q1 2026 report.
Overall, renewables supplied 46.5% of generation, the highest share on record for a first quarter, peaking at 92.2% on 1 January, driven by increased solar and wind output, with the growing backbone of batteries continuing to reshape intraday patterns and suppress the need for thermal generation.

The quarter saw underlying electricity demand across the National Electricity Market (NEM) reach a record of 25,496 MW, up 1.2% on the same period in 2025, but distributed rooftop solar output offset the growth, broadly cancelling out operational demand.
Consumer Energy Resources
The QED reports the introduction of the Australian government’s Cheaper Home Batteries Program supported a rapid increase in
household battery uptake, with cumulative capacity reaching 6,716 MWh at the end of March 2026 and installations rising to 251,119.
By the end of Q1 2026, NSW had reached 2,911 MWh, Queensland reached 1,533 MWh, Victoria, 1,406 MWh, and SA and Tasmania reached 812 MWh and 54 MWh respectively.

AEMO Executive General Manager Policy and Corporate Affairs Violette Mouchaileh, said the quarter highlighted how energy storage and renewables are increasingly shaping electricity market outcomes.
“The significant increase in large‑scale and household battery capacity is changing how electricity is produced, consumed and priced across the day,” Mouchaileh said.
“Grid-scale batteries are increasingly absorbing excess renewable energy during the day and shifting it into the market during evening peaks, helping moderate prices during high-demand periods.”

Grid-scale solar
Grid-scale solar’s 13% output increase from Q1 2025, set a record rising to 2,706 MW, but on Tuesday, 6 January 2026, in the interval ending at 11.30am, grid-scale solar output topped 8,178 MW.
“This exceeded the previous peak of 8,148 MW, set in Q4 2025. Peak variable renewable energy (VRE) output, comprising wind and grid‑scale solar, also reached a new record this quarter, at 13,294 MW in the half‑hour ending at 9.30am on Friday, 9 January 2026. This was 63 MW (+0.5%) higher than the previous record set in Q3 2025,” the QED reports.
Distributed solar
The report shows distributed solar output achieved a record 4,090 MW, up 308 MW (+8.1%) year on year, with NEM-wide operational demand averaging 21,406 MW in the quarter and distributed solar output largely offsetting that demand.

In Queensland, distributed solar output averaged 1,211 MW, up 118 MW (+11%), while in New South Wales (NSW), where underlying demand increased by up to 259 MW or 3%, to average 8,978 MW, thanks to weather conditions and data centre growth, distributed soalr output increased in Q1 by a record 1,338 MW, up 10% or 122 MW.
Victoria’s distributed solar output increased by a record 955 MW, up 48 MW (+5.3%), and in South Australia, a marginal record was set for distributed solar output, averaging 514 MW, up 11 MW, or by a 2.2% increase.
Tasmania also saw a distributed solar output record, averaging 71 MW, up 7 MW or 12%.

There is a number that has defined India’s clean energy ambition for the better part of this decade — 500 GW of non-fossil fuel capacity by 2030. It sits at the heart of every renewable energy policy, every state-level solar tender, every BESS procurement plan. And yet, for all the attention given to generation targets and land acquisition, the real bottleneck in India’s energy transition is rarely discussed with the seriousness it deserves.
The problem is not sunlight. India has plenty of it. The problem is not ambition — that too is in abundance. The problem is what happens after the energy is generated. Getting electrons from a solar panel to a factory floor, from a wind turbine to a hospital, from a storage system to a transmission line — cleanly, reliably, at the right voltage — is a deeply technical challenge. And right now, that challenge is being deferred. At this scale of national ambition, deferral has a cost.
India’s renewable energy story is already impressive. As of March 2026, the country has commissioned 274,688 MW of renewable capacity. Solar leads at 150,260 MW, followed by hydro at 56,586 MW, wind at 56,094 MW, and bio power at 11,746 MW. The trajectory is undeniable.
But 500 GW by 2030 means nearly doubling what exists today — in roughly four years. That is not just a generation challenge. It is a grid management challenge, a power quality challenge, and an infrastructure integration challenge of the first order.
When we talk about India’s energy transition, the conversation gravitates toward megawatts and gigawatts — panels installed, acres under solar, tenders floated. These are important metrics. But they tell us nothing about the quality of the power being delivered.
India’s grid is under stress. Renewable integration has accelerated faster than grid modernization in several regions. Harmonics, voltage fluctuations, reactive power imbalances — these are not distant warnings. They show up as tripped equipment, production stoppages, and penalty charges on electricity bills — costs that quietly drain industrial competitiveness without making headlines.
For India to truly operationalize 500 GW, the country needs a parallel revolution in power conversion infrastructure. Not just more generation assets — but smarter, more resilient systems that handle the volatility of renewable energy at scale, stabilize grid dynamics in real time, and give operators the visibility to manage it all.
India’s solar pipeline is dominated by utility-scale projects — hundreds of megawatts at a time, sitting in Rajasthan and Gujarat, feeding into high-voltage transmission corridors. At this scale, the inverter is not a commodity or a line item. It is the technical heart of the plant — and it either earns its keep over 25 years or quietly costs money every single day.
Central inverters at the 4 MW-plus range determine how well a solar farm performs over its operational life. Efficiency at partial loads, grid fault ride-through capability, harmonic compliance, remote diagnostics — these distinguish a plant that meets its generation targets from one that chronically underperforms. And in India’s climate — dust, heat, humidity, monsoon variability — the durability and thermal management of these systems is not a specification detail. It is a financial variable.
The math is unforgiving. A plant that loses even 0.5% in annual generation due to sub-optimal power conversion loses lakhs of units over its lifecycle. At current tariff rates, that is a number no serious developer can afford to ignore.
Battery Energy Storage Systems have moved from pilot projects to mainstream infrastructure in India remarkably quickly. NTPC, SECI, state DISCOMs — everyone is now factoring storage into their long-term plans. The logic is compelling: storage addresses the intermittency problem that has always been renewable energy’s Achilles heel.
But a battery is only as valuable as its ability to deliver. What drives that delivery — its grid value, commercial value, reliability — is the power conversion system between the battery and the grid. The bi-directional PCS determines how fast energy can be charged and discharged, how precisely state-of-charge is managed, and how seamlessly the system responds to grid signals. Without it, the battery is chemistry waiting for instructions.
At the 5 MW-plus range, a bi-directional power conversion system is critical national infrastructure. It needs to support grid-forming capability, handle four-quadrant operation, and respond to frequency deviations in milliseconds. And increasingly, it must do this without depending on the grid for reference — because in the scenarios where storage matters most, the grid is often what needs to be saved.
Real-world deployments are beginning to demonstrate this. Delta Electronics India recently commissioned a 6.4 MWh / 4 MW BESS at the Central Station of Kolkata Metro’s Blue Line — inaugurated in February 2026, making it India’s first underground metro to deploy large-scale storage for power backup and grid reliability. It is a proof point that this technology, built and deployed in India, is ready for critical infrastructure.
While utility-scale solar and storage dominate headlines, a quieter crisis is unfolding in India’s industrial sector. Factories, data centers, hospital complexes, and commercial parks are increasingly connected to grids carrying significant harmonic distortion and voltage instability — a direct consequence of non-linear load proliferation and rapid renewable integration without adequate compensation infrastructure.
The consequences are real. Harmonic currents cause transformer heating, reduce motor life, trip sensitive equipment, and increase electricity bills through power factor penalties. In a country aggressively pursuing manufacturing competitiveness under Make in India and PLI schemes, allowing poor power quality to silently erode industrial productivity is not a technical footnote. It is an economic liability.
Medium voltage power quality solutions — harmonic suppression, reactive power compensation, real-time voltage regulation — are not optional add-ons. For any serious industrial consumer on a medium-voltage feeder, they are foundational infrastructure. The ROI is straightforward: better power quality means lower energy waste, fewer equipment failures, and the elimination of utility penalties.
Inverters, storage converters, and power quality systems generate enormous operational data — voltage waveforms, fault logs, efficiency curves, state-of-charge trajectories, grid event timestamps. Without a unified monitoring and control layer, this data sits in silos, reviewed only after something has already gone wrong.
Intelligent control room dashboards — systems that aggregate real-time data across an entire energy portfolio, flag anomalies before they become failures, and support predictive maintenance — are not a luxury for large developers. They are how you manage complexity at scale. As India’s renewable fleet grows, its operators will need the situational awareness that grid operators in Germany or California spent a decade building. India needs to build it in four years.
Real-time visibility is not a monitoring feature. It is how you turn 500 GW of installed capacity into 500 GW of reliable, dispatchable energy.
The hardware and software required to solve these challenges does not need to be imported. India’s power electronics manufacturing ecosystem has matured to the point where high-performance central inverters, bi-directional PCS, power quality systems, and monitoring platforms can be designed and produced domestically — calibrated to Indian grid conditions, validated in Indian climates, supported by engineers who understand the operating environment.
Delta Electronics India exemplifies this: its entire energy infrastructure portfolio is manufactured in India, for India, engineered ground-up for the grid realities that define this country’s energy landscape.
India’s 500 GW target is achievable. The generation pipeline is real. The policy momentum is real. The investment appetite is real. But achieving it requires the same rigor in power conversion and grid management that has been applied to capacity planning.
That rigor spans the full energy stack — generating cleanly through PV inverters and wind power converters; storing and dispatching reliably through energy storage and power conditioning systems; distributing without loss through solid-state transformers and power quality restorers; operating intelligently through microgrid controllers and energy management systems; and extending that momentum to mobility through EV chargers.
These are not the supporting cast. They are the infrastructure that determines whether the energy generated actually reaches the people who need it, in a form they can use. The panels capture the sun. The intelligence delivers it.

India’s rising power demand is increasingly being met by renewables, particularly during daytime peak hours. However, rising renewable curtailment shows that grid infrastructure and flexibility are not keeping pace with clean energy growth. With stronger transmission networks, more flexible grid operations, and faster battery deployment, a larger share of evening and night-time demand can also be met through non-fossil sources.

India’s peak energy demand reached a new all-time high of 256 GW on April 26, 2026, surpassing previous peaks of 245 GW on Jan. 9, 2026 and 250 GW on May 30, 2024. Against this backdrop of rising electricity demand, the country generated 464 billion units (BU) of electricity in Q4 2025-26, up 3% year-on-year (YoY), driven by strong growth in non-fossil power generation, particularly solar, which rose by 24%. However, rising instances of renewable curtailment events highlight growing challenges in integrating clean energy into India’s grid.
Generation trends
India’s total electricity generation reached 464 billion units (BU) in Q4 2025-26, up 3%. While coal and lignite generation declined by 1%, generation from solar, wind, nuclear, and large hydro increased by 24%, 11%, 10%, and 7%, respectively. Solar generation reached 48.9 BU, with the highest daily output recorded on 27 March 2026 (658 MU).
Renewable curtailment remains high
Despite higher renewable generation, a significant amount of clean energy was not utilised during Q4 2025-26, with around 27 GW (72 MU) of solar and 4 GW (6 MU) of wind being curtailed. An additional 83 GW (103 MU) of solar and 11 GW (17.5 MU) of wind were curtailed under India’s Tertiary Reserve Ancillary Service (TRAS), a manually activated power system balancing service used to resolve grid congestion. Gujarat in Western India recorded the highest curtailment, highlighting grid integration challenges in high-renewables regions.
Peak demand hits a new high
After recording an all-time peak demand of 250 GW on 30 May 2024, India’s peak electricity demand reached a new Q4 high of 245 GW on 9 January 2026, with overall demand growing by nearly 3% YoY. However, this is the slowest YoY growth in Q4 since 2020-21.
Notably, 88 out of 90 days recorded peak demand during solar generation hours. During the Q4 2025-26 peak demand period of 245 GW, thermal generation accounted for 67% (165 GW) of the total, followed by solar at 20% (48 GW). Maharashtra in Western India recorded the highest state-level peak demand (32 GW) in Q4 2025-26, followed by Gujarat (25 GW) and Uttar Pradesh (23 GW).
Coal power capacity utilisation declines
Coal power capacity plant load factor (PLF) fell from 72% to 69% in Q4 2025-26, despite rising demand. Gas PLF increased from 10% to 12%, while nuclear rose marginally from 78% to 79%. Solar capacity utilisation factor (CUF) declined slightly from 23% to 22%.
Renewables lead capacity additions while no thermal is retired
Capacity additions in Q4 2025-26 were led by renewables, with 16.2 GW added, compared with 2.3 GW of thermal and 0.5 GW of large hydro. India commissioned 2.3 GW of new thermal capacity which was entirely coal-based in Q4 2025-26, down 18% YoY, while no thermal capacity was retired. Meanwhile, 39.4 GW of coal capacity remains under construction, with most projects still in the early stages.

Energy Transition/ Private Equity & Venture Capital
Kenny Fisher April 30, 2026
French cleantech company ROSI announced it has secured over €20 million (USD$23 million) in funding to scale its high-value photovoltaic module recycling facilities across Europe.
Founded in 2017, ROSI specializes in the high-value recycling of end-of-life photovoltaic panels. The company’s process enables the recovery of high-purity strategic raw materials, including silicon and silver, as well as copper, aluminum and glass.
According to ROSI, by 2050, tens of millions of tons of photovoltaic panels are expected to reach end of life, with the company’s process addressing this challenge by recovering high-purity precious materials, offering a circular and value-creating alternative to conventional low-value-added recycling streams.
Building on its first industrial site, ROSI Alpes, the company is advancing its expansion with the development of a new facility in Teruel, Spain. The plant is expected to represent a key step in the industrialization of photovoltaic recycling, featuring an integrated and highly automated processing line designed for large-scale deployment. The facility will have a processing capacity of 10,000 tons per year, producing high-purity recycled materials including silver, silicon, copper, aluminum and glass.
The company said that the project is designed to support the development of a scalable circular model for photovoltaic recycling in Europe, reducing reliance on imported critical raw materials and strengthening regional supply chains.
The new funding included a Series B fundraise and the securing of French and European grants to support the rollout of its industrial projects.
Dr. Yun Luo, President and co-founder of ROSI said:
“Our ambition is to build a European-scale industrial platform for circular management and the production of strategic raw materials, transforming end-of-life solar panels into a reliable source of high-purity materials for the European industries of tomorrow.”
The Series B round was led by InnoEnergy, CMA CGM, the European Innovation Council (EIC), and Spanish family office G3T, and included participation from new international investors alongside existing shareholders.
Romain Girard, investment manager at CMA CGM said:
“ROSI illustrates the kind of industrial circular-economy platform that Europe needs: a differentiated technology, a clear path to industrial scale, a strong contribution to strategic resource resilience, and a tangible potential to reduce the CO2 footprint of the photovoltaic value chain.“
ROSI also announced the appointment of Thierry Galvez as the new director of ROSI Alpes. Galvez brings 30 years of experience in the photovoltaic industry, primarily at Photowatt, and will focus on industrial performance, operational excellence, and support the company’s future expansion in his new role.

CHRISTIANA, Tenn. (AP) — From a distance, the small solar farm in central Tennessee looks like others that now dot rural America, with row upon row of black panels absorbing the sun’s rays to generate electricity.
But beneath these panels is lush pasture instead of gravel, enjoyed by a small herd of cattle that spends its days munching grass and resting in the shade.

The total number of solar arrays across the UK has now reached two million

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it’s investigating the financials of Elon Musk’s pro-Trump PAC or producing our latest documentary, ‘The A Word’, which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
The UK has witnessed a big surge in solar power adoption, with more than 27,000 new installations completed in March – marking the highest monthly total since 2012.
This milestone has propelled the total number of solar arrays across the country beyond two million for the first time.
Government data indicates that 27,607 solar systems were added in March. The Department for Energy Security and Net Zero (Desnz) largely attributed this increase to rooftop solar, with two-thirds of the new installations being panels on homes.
Over the past year, Britain’s solar capacity has expanded by 11.7 per cent, adding 2.3 gigawatts of clean power to the national energy mix, Desnz confirmed.
Energy Secretary Ed Miliband said: “The numbers speak for themselves – the highest monthly installation of solar in over a decade, rising capacity and more than two million solar installations now powering homes across Britain.
“This is our clean energy mission in action – helping families weather global energy shocks, bringing bills down, and getting Britain off the fossil fuel rollercoaster.”
The Government said it is stepping up solar power across homes, schools and communities, giving consent to the UK’s largest solar farm, Springwell Solar Farm in Lincolnshire, driving forward the roll-out of “plug-in” solar panels for balconies and outdoor space and ensuring they are standard on new homes.
Mr Miliband has previously vowed to “double down, not back down” on the transition to clean energy in the light of the Iran war which has led to soaring fossil fuel prices, even as political opponents call for a slowdown on net zero and more oil and gas drilling in the North Sea.
The National Energy System Operator has said solar set new records in March, generating more than 15GW of power for the first time, as the grid nears the milestone of 100 per cent clean power for a short period of time for the first time in history.
Jess Ralston, head of energy at the Energy and Climate Intelligence Unit (ECIU) think tank, said the British public clearly viewed net zero technologies such as solar as the solution to energy bill volatility and back-to-back oil and gas crises.
“They are voting with their feet on accelerating the clean transition through electrification – the logical way to shield households from oil and gas prices soaring as a result of conflict thousands of miles away,” she said.
“Once we have installed solar panels or wind turbines, the wind and sun are free, but we will increasingly need to pay other countries for oil and gas as the North Sea continues its inevitable decline, with or without new drilling.”

India’s low-cost solar is arguably the country’s biggest advantage on the renewable energy front. Solar and wind power are driving the global energy transition, with countries investing heavily to meet climate and energy targets. In India, solar has emerged as the flagship segment, growing from about 3 GW in 2014 to over 150 GW of installed capacity by March 2026.
One of the biggest factors enabling this growth has been the consistently falling cost of solar power. This cost advantage is not just a domestic success story—it is a structural edge that positions India strongly in the global clean energy transition.
Through this blog, we explore how India’s lowest-cost solar has evolved and why it remains central to the country’s future energy pathway.
Solar’s upfront cost is now lower than fossil power, removing a key barrier for capital-scarce economies. 
The Indian solar market has witnessed a dramatic 95% fall in solar costs since 2010, as the solar PV module costs fell from over Rs 200 per watt in 2010 to under Rs 9 in 2024, according to research from the India Energy & Climate Center (IECC) at the University of California, Berkeley.

Recent auction data further reinforces India’s position as a low-cost solar market. Utility-scale solar tariffs have been discovered as low as ₹2.48 per kWh in recent bids, making them among the cheapest globally.
Even hybrid and firm renewable projects—combining solar with wind or storage—are now being bid in the range of ₹3.4 to ₹5.6 per kWh, reflecting improving reliability without a steep cost increase.
This cost competitiveness means solar power is now cheaper than new coal-based generation in many cases, and is comparable to or lower than industrial electricity tariffs. This also makes solar increasingly viable for large-scale deployment without subsidies.
This shall not just be seen as a technological milestone, but also means that India can now feasibly generate—and even store—solar power for round-the-clock use.
According to a recent analysis by Ember, solar combined with battery storage could supply up to 90 percent of India’s electricity demand at a levelised cost of ₹5.06 per kWh ($56/MWh).
This is a critical shift in energy economics. Battery storage, once considered expensive, has seen rapid cost declines as global battery costs fell by 40 percent in 2024, followed by an additional 31 percent drop in 2025
This has solved solar’s biggest limitation – its inability to generate power after sunset. With storage, precious renewable solar energy during daytime can be stored and be dispatched during evening and night peaks, making solar a reliable, dispatchable energy source.
In fact, recent solar-plus-storage projects in India have already achieved tariffs as low as ₹2.7–₹2.76 per kWh, signalling strong commercial viability. This drop was seen in Madhya Pradesh’s maiden solar-plus-storage project in Morena, which recorded a tariff of ₹2.70/kWh.
The energy storage sector is poised for a transformative breakout in 2026, with battery energy storage capacity addition set to surge nearly 10-fold from 507 MWh in 2025 to approximately 5 GWh in 2026. 
From the above analysis, it is clear that low-cost solar represents a major opportunity for India, particularly due to the sharp decline in battery storage costs. This marks a significant shift from solar being a daytime-only resource to a reliable, round-the-clock power source, enabled by storing excess daytime generation for use during non-solar hours. This is exactly what India needs right now.
The economics further strengthen this opportunity. The cost of around ₹2.7 ($0.028) per kWh makes it cost-competitive with, or cheaper than, the average cost of supply in many parts of the world. In Comparison, China continues to maintain the most aggressive cost structure globally, leveraging massive scale and domestic manufacturing to achieve generation costs near $0.027/kWh.
The developed world is seeing a mixed trend. In Europe, costs vary significantly by market. While sunny regions like Portugal and Spain consistently hit the lower end of the spectrum – near $0.022/kWh – northern or more complex grid markets see higher costs.
In the US, while the base unsubsidized LCOE remains higher than in India and China, federal tax incentives (ITC/PTC) can significantly reduce the effective cost for project owners, narrowing the gap – often bringing the realised cost for developers into the $0.020–$0.045/kWh range.
The scale of the opportunity is substantial for India. By leveraging low-cost solar and storage, India can meet a large share of its growing electricity demand without building significant new fossil fuel capacity. This also improves system flexibility, as stored solar power can be dispatched when needed, helping balance supply and demand more efficiently.

From pv magazine Spain
Rosi, a French cleantech company specializing in the recycling of end-of-life PV modules, has secured more than €20 million ($23.4 million) in funding to accelerate its next growth phase. The funding will support the commissioning of a new facility in Teruel, Spain, which will have a processing capacity of 10,000 tonnes per year.
The Series B round attracted new international investors alongside existing shareholders, including InnoEnergy, CMA CGM, the European Innovation Council (EIC) and Spanish company G3T. Finadvice, a Zurich-based corporate finance consultancy specializing in deeptech, acted as strategic financial advisor and also participated as an investor, together with family offices from Switzerland and Poland.
Through its Inspire-PV project, supported by the European Climate, Infrastructure and Environment Executive Agency (CINEA) under the European Innovation Fund, Rosi aims to accelerate the industrial deployment of its PV module recycling solutions. The company says it is leveraging experience gained at Rosi Alpes, its first industrial plant, to support the scale-up of the new Teruel facility.
“This new plant will represent a significant milestone in the industrialization of photovoltaic recycling, with an integrated and highly automated line designed for large-scale implementation,” the company said. The facility will produce high-purity secondary raw materials, including silver, silicon, copper, aluminium and glass.
According to Rosi, once preliminary studies are completed, the plant will enter the construction phase as soon as technical specifications are finalized and the necessary permits are obtained.
Rosi already operates Rosi Alpes in France and was among six industrial operators selected in a national tender led by Soren, France’s approved body for the collection and treatment of end-of-life PV modules, to expand recycling capacity. Alongside Rosi, Envie 2E, Galloo, RVE and First Solar were selected, with facilities distributed across mainland France and overseas territories. Collectively, the operators are expected to process more than 45,000 tonnes of PV modules per year.
Beyond France, Rosi also operates in the United Kingdom, Germany and Switzerland in collaboration with Sens eRecycling.
Rosi’s recycling technology is based on a pyrolysis process that separates the different materials present in PV modules. Pyrolysis is a thermal decomposition process carried out in the absence of oxygen, widely used in industry to break down organic materials and recover valuable constituents.
“Silver represents less than 0.1% of a solar module, but accounts for a significant share of its value,” said Yun Luo, co-founder and president of Rosi Solar. “The same applies, to a lesser extent, to silicon, copper and high-purity glass.”
The company has developed a low-intensity thermal and chemical treatment process enabling the recovery of high-value metals and materials, as well as a patented process for reintegrating silicon into industrial applications. With support from the French Environment and Energy Management Agency (Ademe) for proof-of-concept validation, Rosi has also focused on purifying silicon recovered from wafer-cutting waste.
In 2019, Rosi developed a second extraction project with Veolia, again at proof-of-concept stage and co-financed by Ademe to develop an industrial prototype. The company’s customers include potential users of recovered materials, particularly in the chemical industry.

WICHITA, Kan. (KWCH) – A renewable energy project is under consideration for the construction of a solar farm and battery storage facility on about 1,500 acres near Wichita.
On Wednesday, the Wichita-Sedgwick County Metropolitan Area Planning Commission will consider a request from Galena Solar Project, LLC to rezone 1,490 acres from about 119th Street West to a little east of South Ridge Road and from West 47th Street South to West 63rd Street South. This is just southwest of Wichita.
The planning commission’s agenda recommends approval of the project “with conditions.”
The renewable energy project calls for 600,000 solar panels and a battery system on what is currently farmland.
People living near that farmland are pushing to stop the project.
“It’s gonna affect your family… health-wise, view-wise,” said Beverly McKibban, who’s lived about a half-mile west of S. Ridge Rd. and W. 47th St. S. with her husband, Bill, for over 35 years. “We know that that’s going to lower our property value. We’re concerned about the water, the wildlife.”
Part of the Galena Solar Project would be located directly in front of the McKibbans’ property. They know it’s something they would have to look at for the rest of their lives.
“We’ll have to see it everyday, and as we drive in and out it’s going to be all in our location,” said Beverly.
As they consider selling their property and moving into a smaller home, Bill says they’ll be left with the reality of trying to sell a home with a solar farm essentially in its front yard. “If I had just moved out here or was looking at this place to buy and looked out my front door and see solar panels, probably wouldn’t do it.”
As of March 11, the Sedgwick County Commission placed a one-year moratorium on any applications for Battery Energy Storage Systems (BESS). However, the planning commission explained that because the applicants (Galena Project, LLC) “submitted the current application prior to the moratorium, the current application can be processed.”
“This application was put in, I believe in January, and we didn’t put the moratorium on batteries, which is a one-year moratorium, until March,” explained Sedgwick County Commissioner Jeff Blubaugh.
When the county approved the moratorium last month, commissioners said they wanted to create regulations for large-scale renewable energy projects, which are becoming more common across the country.
Landscaping is one piece addressed in the renewable-energy project application for the acreage south of West Wichita. The Wichita-Sedgwick County Metropolitan Area Planning Commission’s staff report on the project includes a section in which developers promise to keep existing trees and add shrubs and slatted fences to somewhat hide the solar panels.
A “Solar Glare Hazard Analysis” was also run to make sure that sunlight reflecting off the panels doesn’t bother pilots landing at nearby Eisenhower National Airport or drivers on neighboring gravel roads.
Considering the potential economic impact, developers said that “once operational, the anticipated revenue of the project is expected to be $82 million per year from the sale of power under a power purchase agreement (PPA) that would run for the life of the project.”
“This is approximately a $17,900% increase over traditional agricultural production and that increase would be reflected in additional revenue for the county,” an analysis of the proposed project read. “The total annual taxes paid to the county will increase by 16,106% and will average roughly $2.35M annually.”
Bill and Beverly are afraid county leaders are not in touch with people’s concerns, since they don’t live near where the project will be constructed.
On Wednesday’s meeting, if the Wichita-Sedgwick County Metropolitan Area Planning Commission signs off on the renewable energy project outside the city, the project would then need approval from the Wichita City Council and the Sedgwick County Commission to move forward.
The meeting will take place at 9 a.m. at the Ronald Reagan Building in downtown Wichita.

Renewables accounted for about 52% of the overall power capacity mix
April 30, 2026
Follow Mercom India on WhatsApp for exclusive updates on clean energy news and insights
Solar power accounted for 28.4% of total installed power capacity and 55% of total installed renewable energy capacity as of March 2026, up from 26.5% and 52.7%, respectively, in the previous quarter.
Solar project installations have increased by about 12% quarter-over-quarter (QoQ) and 46% year-over-year (YoY).
India’s renewable energy capacity, including large hydroelectric projects, made up 51.7% of the country’s cumulative power capacity, with 276.5 GW installed at the end of the first quarter of 2026, according to data from the Central Electricity Authority (CEA), the Ministry of New and Renewable Energy (MNRE), and Mercom’s India Solar Project Tracker.
The share of renewable energy in the power mix was 50.2% of total installed capacity in Q4 2025 and 46.1% in Q1 2025.

India generated approximately 52.2 billion units (BU) of solar power in Q1 2026, a 24.3% YoY increase. On a QoQ basis, generation increased by about 27% from 41.2 BU to 52.2 BU.
Large hydro, with a total installed capacity of 51.4 GW, accounted for nearly 9.6% of the total installed power capacity as of March 2026. There was a significant addition to hydropower capacity, with NHPC commissioning the Subansiri Lower Unit-3 and Unit-1 in Q1 2026, adding a total of 500 MW of dispatchable capacity.
Wind capacity stood at 56.1 GW at the end of Q1 2026, representing 10.5% of total installed capacity and contributing over 20% of total renewable energy capacity.
Biomass and small hydro contributed 2% and 1% to the total installed power capacity as of March 2026, respectively.
Energy from conventional sources
At the end of Q1 2026, the country’s installed conventional power capacity stood at 258.1 GW, accounting for 48.3% of all installations. This represents a decrease from 49.8% in the previous quarter and 53.9% in the same period last year.
The share from thermal sources is dominated by coal (41.5%), followed by gas (3.8%), nuclear (1.6%), lignite (1.2%), and diesel (0.11%).
Telangana, Tamil Nadu, and West Bengal added 2.26 GW of coal-based thermal capacity in the quarter, with Telangana and Tamil Nadu accounting for 1.6 GW, highlighting continued reliance on baseload power procurement.
Cement and steel industries converted a total of 114 MW of captive thermal power capacity to independent power producer status.
The Ministry of Power has released the Draft National Electricity Policy, 2026, for public consultation, aiming to align India’s power sector with the country’s long-term energy transition goals. Its central objective is to ensure a reliable, affordable, and high-quality 24×7 electricity supply through a financially viable and environmentally sustainable power sector.
The Central Electricity Authority has projected that India’s installed power capacity requirement will reach 1,121 GW by FY 2036, with the share of fossil fuel-based generation declining from the current 75% to 50%.

This comes after a one-year moratorium was placed on applications for solar farms.

(Lawrenceburg, Ind.) – The Dearborn County Plan Commission met on Monday to discuss the creation of a solar farm advisory committee. 
The proposed advisory committee would work toward amending commercial ordinances regarding solar, battery energy storage and data centers. However, the Plan Commission voted 8-0 against the creation of a citizen advisory committee. 
The vote comes after Dearborn County Commissioners approved a one-year moratorium on solar farms. The moratorium halts the processing of applications for commercial solar farms and battery storage facilities in Dearborn County.
Linea Energy has been at the forefront of discussion, as the company wants to develop solar and battery storage on 1,000 acres in the Manchester area.
Oppositions are concerned for the environment, fear of lower property values, and loss of an agricultural setting for homeowners.
Dearborn County Commissioners will be next to discuss the creation of a solar farm advisory committee. 
Monday's Dearborn County Plan Commission meeting can be found at pc 04/27/26.

SOUTH LAKE TAHOE, Calif. – The South Tahoe Public Utilities District (STPUD) had a “ribbon cutting” of sorts on Wednesday. With no ribbon to be seen, the STPUD board threw the switch on for the largest solar array in the Tahoe Basin, celebrating renewable energy and the efforts of the community.
This project was years in the making and director Shane Romsos stressed how needed such a project was. “Energy is one of our fastest growing costs,” he said. The solar array spans 1.5 acres and will generate 1.4 megawatts of power per year—roughly a third of the energy requirements of the wastewater treatment plant.
The solar array will offset over 1,500 tons of carbon dioxide per year and is estimated to produce $190,000 in savings in its first year. It was bought through a power purchasing agreement with the Staten Group, who also constructed and installed the 2,112 panels.
The panels are set four feet above the ground in preparation for snow seasons, and are bifacial, meaning they can absorb sunlight (and reflected sunlight from the snow) from both sides of the panel.
Romsos thanked their partners and collaborators, including the Tahoe Regional Planning Agency, the city of South Lake Tahoe, El Dorado County and Liberty Utilities. He also thanked staff, saying, “Since the idea was formed in 2019, our staff has worked tirelessly to make this happen.”
Board director Nick Exline said, “This was a really long journey to get here… this was an effort of ‘we.’” He thanked the community for their support and added, “We have a unique opportunity as a public utility. We want to work together so that Tahoe can bring forth its own energy future, because this sets a pathway to where we’re going to go in the future.”

APTEL issues a stay on MERC’s tariff order limiting energy banking
April 30, 2026
Follow Mercom India on WhatsApp for exclusive updates on clean energy news and insights
India’s solar manufacturing sector is expanding unevenly, with module production scaling rapidly while cell manufacturing continues to lag. Despite policy support and strong domestic demand, the gap highlights underlying technology and market constraints. Module manufacturing benefits from simpler assembly processes and lower capital requirements, but cell production remains capital-intensive and technology-driven, requiring advanced infrastructure and continuous upgrades.
The Appellate Tribunal for Electricity (APTEL) issued an interim order staying the issuance of disconnection notices and electricity bills raised under the new power banking mechanism introduced by the Maharashtra Electricity Regulatory Commission (MERC). Recently, MERC modified aspects of its multi-year tariff order, revising time-of-day banking rules and rationalizing the rebate structure to better align with regulatory principles and solar consumption patterns.

Solar panel sales have risen sharply since the start of the Middle East conflict, according to Octopus Energy – with households opting for larger arrays of roof panels. Sales were up 50% since after the war pushed oil and gas prices up.
Consumer expert Holly Hamilton explains whether they are worth your cash, and the grants available that could help you get them installed in your home. Plus, how, in just a few months' time, you could be able to buy plug-in solar power from supermarkets.
The UK is experiencing a sharp rise in demand for solar panels as households look for ways to shield themselves from rising energy bills and global market instability.
Industry analysts say the surge is being driven by a combination of higher energy prices, falling installation costs and rapid improvements in home energy technology. Many households are now turning to solar as a way to gain greater control over their energy use.
Rising global energy prices, intensified by geopolitical instability, have pushed up the cost of oil and gas. With the energy price cap set to reset in July, many households expect bills to rise again and are acting early to reduce their exposure.
Solar energy is increasingly seen as a route to energy independence, offering families a buffer against future price shocks.
The cost of solar systems has dropped by around 40% since 2020, and installations currently benefit from zero VAT. This has made solar more accessible to a wider range of households.
There has also been a significant shift in technology. More homeowners are pairing panels with battery storage, allowing them to store electricity for use when prices are higher or sunlight is limited. While battery systems remain relatively expensive, with only around one in 20 homes currently using them, they are becoming more affordable.
Take up varies across the country, with the south west of England seeing the highest adoption rates.
Experts say solar panels can offer substantial benefits, but they are not suitable for everyone.
Pros
Lower energy bills: Households can cut bills by 55 to 75 percent depending on system size and usage.
Greater energy security: Solar provides a hedge against future price rises, especially when paired with a battery.
Faster payback periods: Falling costs mean households can recover their investment more quickly.
Environmental benefits: Solar reduces carbon emissions and reliance on fossil fuels.
Cons
High upfront cost: A typical system costs upwards of £6,000, with batteries adding significantly more.
Weather dependent output: Solar generation drops in winter, meaning households still rely on the grid.
Potential price rises: Supply chain pressures, including shipping and lithium costs, may push system prices up by 10 to 15 percent in the short term.
Variable savings: Benefits depend on household energy use, system size and tariff.
Policy uncertainty: Changes to tariffs or government incentives could affect long term returns.

A new wave of plug in solar kits, already popular in Germany, could soon make solar more accessible to renters and people living in flats.
These compact systems, costing only a few hundred pounds, can be placed on balconies, gardens or shed roofs and plugged directly into a standard 3 pin socket. They are capped at 800W for safety and are not designed to power an entire home, but can offset the cost of running small appliances such as a small fridge or Wi Fi router.
Retailers including Lidl, Amazon and Iceland are preparing to stock the kits once new government safety rules are finalised, expected in summer 2026.
Several schemes are available to help households with the cost of installing solar panels.
Warm Homes (England)
A major scheme offering fully funded upgrades, including solar panels, for low income households (typically under £36,000) living in inefficient homes (EPC D to G). Grants can exceed £15,000 and are available to homeowners and private tenants with landlord permission.
ECO4 Scheme (England, Wales and Scotland)
Funded by energy suppliers, ECO4 provides free or heavily subsidised solar panels, insulation and heating upgrades for households on certain benefits or low incomes. The scheme runs until the end of 2026.
Smart Export Guarantee (SEG)
Not a grant, but a payment scheme where households earn 5 to 15p per kWh for electricity exported back to the grid. Systems must be installed by an MCS certified or equivalent installer.

The Wichita-Sedgwick County Metropolitan Area Planning Commission is taking a look at a renewable energy project proposal for the construction of a solar farm and battery storage facility on about 1,500 acres southwest of Wichita. The request is from Galena Solar Project, LLC, who are asking to rezone 1,490 acres from about 119th Street West to a little east of South Ridge Road and from West 47th Street South to West 63rd Street South.

The planning commission’s agenda recommends approval of the project, “with conditions.” The renewable energy project calls for 600,000 solar panels and a battery system on what is currently farmland. If the Wichita-Sedgwick County Metropolitan Area Planning Commission signs off on the renewable energy project outside the city, the project would then need approval from the Wichita City Council and the Sedgwick County Commission to move forward.

In October 2025, Tuck School of Business professor Bryan Bollinger ’03, Th ’03 co-authored a National Bureau of Economic Research study about the impacts of American solar panel tariffs on domestic solar energy development with Cornell professor Todd Gerarden, Yale professor Kenneth Gillingham ’02 and Duke professor Daniel Xu. The study found that tariffs on solar panels made in China led to a decrease in domestic solar manufacturing and installment. 
As of November 2025, tariffs were at 47.5% on all Chinese exports. Earlier in 2025, President Donald Trump imposed sweeping tariffs on all Chinese exports, and retaliatory tariffs reached over 130% in April 2025.
Tariffs on Chinese-made solar panels have risen in the last decade-and-a-half. The federal government first imposed tariffs on solar panels made by Chinese manufacturers in November 2012 and increased them in December 2014 under the Obama administration. The Trump administration imposed additional tariffs in 2018 and 2019, which were further extended under the Biden administration. In 2024, solar panel tariffs were set at 50%, according to the Department of Energy.
The Dartmouth sat down with Bollinger to discuss his background, his research on tariffs and the future outlook of solar energy development in the United States.
Tell us about your background in renewable energy development and policy research.
BB: My interest dates back to my time as a student at the Thayer School of Engineering. I considered going back to work on renewable energy, but I ended up studying marketing at Stanford University, focusing on applied economics. One day, I met for coffee with a Dartmouth friend, Kenneth Gillingham ’02, at Stanford, and we realized we had a shared interest in solar and how it could move us away from fossil fuels and create household energy independence. We began our first couple of projects looking at the diffusion of solar technology.
What was the rationale behind this research project? 
BB: Since some of the cost of tariffs gets passed down to consumers, our goal was to estimate how increasing prices for residential solar adopters — so, households — and commercial solar systems impacted consumers. On one hand, American installers would be worse off as they performed fewer installations and thereby got fewer profits, but on the plus side, you would have a potential increase in domestic solar panel manufacturing. One of our tasks was to weigh these trade-offs and see to what extent those tariffs helped American manufacturers versus hurt installers and consumers. We also accounted for revenue impacts for the U.S. government, which saw a moderate increase.
What were the overall impacts of tariffs on imported solar panels?
BB: The net reduction in solar installations in the U.S. and losses for installers outweighed the gain in American manufacturing jobs. The gain in domestic production was fairly small, and in terms of energy independence, they don’t really materialize in the short term. Although we saw an increase in domestic manufacturing of solar panels, all of the wafers  — which are then assembled into solar cells, and then panels — were essentially still being imported from China. Also, most of the increased installations and manufacturing capability in the U.S. following tariffs are still from internationally-owned firms, not domestic manufacturers. 
What alternative policies did your research find to be more effective in sustaining solar energy development growth?
BB: We found that a manufacturing subsidy for domestic manufacturers would be more beneficial than solar tariffs. They would obviously cost the government money, but after quantifying the different effects, we found that the total gain in surplus for consumers, installers and manufacturers would be higher than the additional cost to the government for those manufacturing subsidies. If we really want to use tariffs as a policy tool to increase U.S manufacturing, we need to settle on a consistent tariff level, maybe in conjunction with a domestic manufacturing subsidy.
Under the current on-and-off-again regime, I think it’s hard for U.S. manufacturers to make optimal decisions. As a U.S. manufacturer, if I think tariffs might only be on for a brief period of time, I have little incentive to invest a lot of upfront money for new manufacturing capabilities. If tariffs are turned off, my costs now are still too high relative to prices on the international market. 
What are some challenges in researching solar industry development when tariffs are ever-changing?
BB: From a research perspective, changing policy landscapes provides variation, which allows us to learn more about how agents respond to changes, but one of the challenges is that we don’t get to see the real long-term effects. For this project, we avoided making long-term predictions and extrapolating much beyond the data.
We looked at the range of data and estimated what would have happened under a counterfactual. With tariffs, we can estimate consumers’ and firms’ responses to those tariffs. Alternatively, we could turn off tariffs and see, for instance, how it would affect prices, demand and what firms would do if they were optimally sourcing their solar panels from different production locations.
What recommendations do you have for households that are currently considering switching to solar?
BB: One of the challenges is being able to forecast what future costs will look like. You’re making a long-term investment, so it can be challenging to know whether or not it makes sense to wait. Consumers need to get quotes from multiple installers. It can become difficult to compare prices when one installer advises you to install many more panels than another installer, but many online tools out there make the decision easier by allowing you to compare financial benefits.

Home – Tech – He wanted to cut his electricity bill with solar panels on his balcony and ended up facing an unexpected court ruling
What happens when a simple money-saving idea meets apartment-building rules? In Gdansk, Poland, a court has ordered a resident to remove solar panels from his balcony even though the system reportedly cut his electricity bill by more than one-third and had support from around 60% of residents in his housing cooperative.
The ruling came from the Gdansk-Północ District Court in a first-instance case identified in court records as V GC 430/25, and local coverage says the homeowner plans to appeal.
On the surface, this looked like a modest clean-energy upgrade. The resident first installed two balcony panels in 2023 as part of an 800-watt kit with mounting hardware and a microinverter for home use.
He later added a third panel, bringing the setup to 1.2 kilowatts. Reports in Poland say Energa-Operator replaced his meter with a bidirectional one and recognized him as a prosumer, meaning he could both consume and feed electricity into the grid.
For anyone staring at a stubborn electric bill month after month, that kind of savings is hard to ignore.
However, the case was never only about the hardware. It was about proof, permissions, and who gets the final say over changes to a shared residential building.
According to recent reporting, the court sided with the housing cooperative because it found no reliable way to verify whether the signatures backing the installation actually came from eligible cooperative members.
That may sound like dry paperwork, but it was enough to decide the case.
And that is the bigger story here. Balcony solar is often pitched as an easy entry point into home energy generation, especially for people who do not own a roof.
Even Energa’s own balcony solar guidance says residents need approval from a housing community or cooperative before installation, alongside technical requirements for the railing and mounting system.
In practical terms, that means the tech may be ready, but the rules are still catching up.
For the most part, that legal gray area is what makes this case worth watching beyond one apartment in Gdansk.
If courts keep treating verification and building governance as the deciding issue, then balcony solar may remain more complicated than many residents expect. Small panels can be easy to buy. Getting everyone to agree is the hard part.
The official court ruling was published on Poland’s Portal Orzeczeń Sądów Powszechnych.

From pv magazine USA
Beatbot has introduced the iSkim Ultra to the residential pool market, a device that aims to reduce filtration load by capturing surface debris before it sinks.
The unit is powered by a top-mounted 24 W solar panel that supports continuous operation, supplemented by a 10,000 mAh battery for overnight cleaning cycles. For environments with limited sunlight, the system includes a 24 W magnetic wireless charging dock.
The hardware is built around a seven-motor drive system and 20 sensors, including tri-ultrasonic sensors and a six-axis IMU, allowing the unit to navigate pool shapes and avoid obstacles. The cleaning mechanism features a 265 mm front roller brush that feeds a 9-liter debris basket. Beatbot states the basket can hold between 400 and 800 leaves depending on their size.
Beyond physical debris removal, the device integrates a pump system that dispenses a natural clarifying agent to manage oils and fine particles. This feature is controlled via a mobile app, which also handles manual steering and software updates. The iSkim Ultra is priced at $1,499 and is designed to handle daily surface maintenance without manual effort.
The autonomous pool skimmer features a 9-liter filter capacity, capable of collecting approximately 400 to 800 medium-sized leaves before requiring emptying. For intelligent navigation, it utilizes 20 high-perception sensors, including tri-ultrasonic sensors and a 6-axis IMU, allowing it to move precisely and avoid obstacles.
Cleaning efficiency is enhanced by a 265 mm front roller brush, which captures debris effectively across a wide path. Additionally, the system is driven by seven high-performance motors.

InfoLink’s market research reveals that the global Solar encapsulant shipment ranking for 2025 remained relatively stable, with global module output reaching approximately 646 GW. 
Based on calculations, the combined shipment volume of the top three encapsulant companies accounted for more than 65% of global supply, up from 2024. This data was shared in InfoLink’s global Solar encapsulant shipment ranking report for 2025.
Encapsulants are among the essential materials within the core technology landscape of PV modules and are undergoing profound shifts in demand, technological innovation, and competitive dynamics. InfoLink’s ranking is based on external sales volume data from its PV Bill of Material Market Report, drawing on publicly available company information and market research. In case of discrepancies, the companies’ official figures will prevail.
According to InfoLink’s market research, the 2025 global Solar encapsulant shipment ranking remained relatively stable, while divergence among leading players continued. At the same time, competition at the top has gradually eased, with the top three players further consolidating their positions. The research is based on publicly available company information and market analysis, with companies’ official figures prevailing in case of discrepancies.
Within the solar industry, encapsulants have become a critical component of the module technology landscape, reflecting ongoing shifts in demand, innovation, and competitive dynamics.
Expectedly, the top 3 firms are all China bsed. First Applied Materials ranked first, with shipment volumes broadly flat compared to 2024, maintaining its leadership position. Sveck ranked second, with performance in line with previous trends and stable operations.
Betterial secured third place once again. After entering the global top three in solar encapsulant shipments in 2024, the company maintained strong shipment performance in 2025, with its ranking holding steady. Compared with earlier shifts in the competitive landscape, its performance reflects greater continuity and stability.
Overall, following the structural realignment in 2024 that brought Betterial into the top three, leading positions remained largely unchanged in 2025. Competition has shifted from position reshuffling to structural consolidation, with market share continuing to concentrate among leading manufacturers.
As module manufacturing capacity continues to expand in non-China markets, encapsulant suppliers have increasingly sought opportunities outside China over the past two years. Coupled with the rapid expansion of encapsulant capacity in earlier periods, profitability across the sector has gradually declined.
Although excess capacity additions in 2025 have begun to clear at a slow pace, overall supply remains ample. In addition to frequent trade barriers affecting key PV module materials, the encapsulant industry itself is now facing mounting trade restrictions.

Following India’s previous anti-dumping (AD) investigations into EVA imports from multiple countries—including China, Malaysia, South Korea, Saudi Arabia, and Thailand—in 2018 and 2023, the country initiated another AD investigation in September 2025. This time, it targeted POE/EPE imports from multiple countries, including China, South Korea, Thailand, and Vietnam.
This development suggests that a concentrated, single-location production strategy offers limited protection against trade-related risks, prompting manufacturers to accelerate diversification of their manufacturing footprints.
Profitability across the encapsulant sector has gradually declined, particularly against the backdrop of a broader downturn in the solar industry over the past two years. This trend has been compounded by rapid capacity expansion in earlier periods.
Encapsulants, as part of auxiliary materials, account for an increasingly important share of solar module production costs. Since the beginning of 2026, sharp swings in metal prices, the impact of conflicts in the Middle East, and gradual capacity clearance in the encapsulant sector have pushed manufacturers to focus more closely on cost control and the safe, stable supply of auxiliary materials.
This not only improves production efficiency but also strengthens module competitiveness and profitability.
Among the top three encapsulant suppliers, FIRST has steadily increased its supply share outside China, while Sveck remains primarily focused on domestic supply.
Betterial has established production bases in Indonesia and Türkiye, meeting customer demand and strengthening resilience to trade barriers through differentiated site selection. Leveraging its overseas footprint and sales network, the company derives a relatively high share of shipments from non-China markets, making it one of the few suppliers with such a high overseas shipment ratio.
Based on 2025 data for the non-China portion of global encapsulant shipments, Betterial ranked second in solar encapsulant shipments outside China.
