As the solar industry pushes for higher output and leaner manufacturing, pushing performance limits requires more than cutting costs. True market success depends on ensuring that next-generation designs can endure decades of field operations without unexpected degradation.
The TaiyangNews Reliable PV Module Design Online Conference, taking place on Thursday, October 15, 2026, from 09:30 to 13:00 CEST, will bring together leading module manufacturers, material and component suppliers, testing organizations, and other industry experts to discuss the latest module products and design concepts, material choices, quality considerations, and reliability challenges, from cells, glass, encapsulants, backsheets, and interconnection technologies to complete module architectures.
Djamel Eddine Mansour, Product Manager at JA, will discuss how the layout redesign of the company’s DeepBlue 5.0 platform has improved reliability.
The conference is just 2 days away. Register for free here.
LONGi PotisEdge, LONGi’s energy storage subsidiary, has started operations at its smart manufacturing base in Suzhou, Jiangsu province. Designed for an annual capacity of 50 GWh, the facility will manufacture, test, and deliver utility-scale, commercial and industrial (C&I), off-grid, and microgrid energy storage products for global markets.
The utility-scale storage integration line is scheduled to reach an annual capacity of 31 GWh by October 2026 and expand to 50 GWh in the first half of 2027. The C&I storage line is expected to exceed 10,000 units of annual production by the end of LONGi said the facility extends its ‘LONGi ONE’ strategy into manufacturing and will support the expansion of its global energy storage business.
In an exclusive interview with TaiyangNews earlier this year, LONGi’s Dennis She explained why the company is combining PV and battery storage under the LONGi ONE platform, its market focus, and how it sees integrated energy systems evolving (see LONGi Explains Its Integrated Solar-Plus-Storage Strategy).
Liaoning’s provincial development and reform commission has selected 22 new energy storage projects for the first batch under China’s 15^th Five-Year Plan (2026-2030), with a combined power capacity of 3.15 GW. The project owners include CATL and CR Power. The projects will be developed in Shenyang, Dalian, Yingkou, and Chaoyang, covering independent storage, grid-side storage, and renewable energy-plus-storage applications.
The selected projects will use lithium iron phosphate (LFP) batteries, vanadium redox flow batteries, and compressed-air energy storage, with an emphasis on long-duration technologies. The largest is a 350 MW/2,800 MWh compressed-air energy storage facility in Gaizhou, Yingkou, providing approximately 8 hours of storage. Shenyang’s Shenbei New Area will host a 200 MW/800 MWh vanadium flow battery station, while several other projects will use electrochemical storage systems.
Flexible thin-film gallium arsenide (GaAs) solar cell developer DR Technology reported that its independently developed triple-junction cell achieved 38.3% power conversion efficiency under the AM1.5G standard spectrum. Fraunhofer ISE tested and certified the result, which the company says exceeds its July record of 38.0%.
DR Technology said it is the only Chinese company to have achieved volume production and aerospace validation of high-efficiency flexible thin-film triple-junction GaAs solar cells. The company says it has deployed its products on several commercial satellites, which are operating in orbit. The cells are also intended for applications where low weight and high efficiency are critical, including long-endurance near-space unmanned aerial vehicles (UAVs).
Earlier this year, Shanghai’s ‘Xingshu Plan’ space computing constellation adopted perovskite tandem solar technology to power its central computing satellite, stating it is significantly less expensive than GaAs space cells (see China Solar PV News Snippets).
Guangdong has launched mechanism price bidding for 2026 renewable energy projects, setting an initial full-year bidding volume of 7.934 billion kWh for distributed PV.
The bidding is open to distributed PV projects that have entered operation or are committed to doing so between June 1, 2025, and October 31, 2027, and are not already covered by the mechanism. The bidding price must fall between RMB 0.200/kWh and RMB 0.400/kWh, with the resulting mechanism price applying for 12 years.
The maximum declared share of electricity covered by the mechanism is 80% for distributed PV projects connected at voltage levels below 110 kV and 70% for other distributed PV projects. Separate rules will apply to offshore PV projects included in provincial development pilot programs.
A recent assessment by the Guangdong Provincial Energy Bureau found that the province had another 24.21 GW of capacity available for new grid connections (see China Solar PV News Snippets).
