Recently, JinkoSolar officially launched “Sunny 365,” a comprehensive series of integrated PV-storage solutions for the commercial and industrial market. The company simultaneously introduced dedicated design, delivery, warranty, and service platforms, offering a one-stop, full-stack PV-storage project model that spans everything from standalone PV and storage products to solution adaptation, customized fine-tuning, delivery and deployment, operations and maintenance management, and business implementation. This provides a standardized implementation pathway for the commercial and industrial sectors to build their own PV-storage projects at low cost, with minimal space requirements, and rapid deployment.
Faced with the high overlap between daytime peak operating hours in the retail sector and grid peak-hour electricity rates—where electricity costs erode profits, demand-side penalty fees escalate, and power rationing frequently leads to product spoilage—traditional energy consumption models are becoming unsustainable under these multiple pressures. Distributed PV-storage technology is evolving from a supplementary solution into core infrastructure for reducing costs and improving efficiency in the retail industry. As solar-plus-storage applications become more widespread, it has become a trend for supermarket operators to build their own dedicated solar-plus-storage projects using idle rooftop space. However, they have long faced four major challenges: a confusing array of options, difficulties in matching solar and storage systems, high integration costs, and cumbersome post-installation operation and maintenance. Procuring modules, energy storage systems, and other software and hardware separately, while coordinating technical resources from multiple vendors, results in long implementation cycles and significant investment, keeping the barriers to entry for small and medium-sized supermarkets high.
Addressing the diverse needs of retail stores of various sizes, JinkoSolar’s “Sunny 365” solar-plus-storage solution for supermarkets leverages the high-efficiency Tiger Neo 3.0 modules and the SunGiga G2 series of liquid-cooled commercial and industrial energy storage systems to provide the retail sector with the highest-performing solar-plus-storage solution.
Tiger Neo 3.0 Modules: LeadingThe Champion of Rooftop Power Generation
1. Higher power output: With a power output of up to 670W and a conversion efficiency of 24.8%, it generates more electricity per square meter of rooftop area;
2. Exceptionally High Bifaciality: Bifaciality reaches 85% ± 5%, far exceeding the national standard of 75%, efficiently capturing ground and ambient scattered light
3. Excellent Temperature Coefficient: As low as -0.26%/°C, resulting in minimal power loss at high temperatures;
4. Low Linear Degradation: 1% degradation in the first year, followed by only -0.35% annual degradation thereafter, ensuring power generation returns throughout the 30-year lifecycle
5. ExceptionalEnhanced Low-Irradiance Performance: optimized for energy captureYield gains of over 4% against BC modules under conditions such as cloudy or rainy days, as well as at dawn and dusk
6. UltimateCertified Safety Performance: Certified to both IEC and UL Class A standards, meeting the highest top-tire fire safety standards in the photovoltaic industry;
7. Enhanced Weather ResistanceProtection Against Extreme Weather: hail resistance up to 55 mm (as optional versus standard version of 25 mm) and rear wind load resistance of -5,000 Pa, designed for demanding climatic conditionsmaking it suitable for extreme climatic environment.
SunGiga G2 BESS
1. Exceptional Advanced Energy Efficiency (Maximizing Returns). 90% AC-side energy efficiency: Leveraging liquid cooling with ultra-low power consumption and our proprietary PCS, delivering a 2% daily net profit surplus.
2. Strict Temperature Differential Control <2°C: Exclusive 26-point high-density temperature control maintains a temperature differential of less than 2°C, effectively suppressing cell degradation, ensuring 8,000 charge cycles, and improving the cost per kilowatt-hour over the entire lifecycle.
3. Wide Operating Temperature RangeAll-Climate Operation: Wide temperature range of -30°C to 55°C, delivering stable performanceensures uninterrupted revenue generation in demandingextreme cold and heat conditions.
4. Material-Level Thermal Barrier: A nano-insulation layer is embedded between battery cells to prevent the spread of thermal runaway in a single cell
5. Full-metal encasement combined with a flexible circuit board design eliminates significantly reduce the risk of short circuits and fires at the physical source
6. Multi-Sensor Fusion for Rapid Fire Suppression: The system employs multi-dimensional joint detection and is equipped with a perfluorohexane gas fire suppression solution, silently containing emergencies within secondsa short time;
7. Full-Stack Early Warning: The BMS monitors abnormal cells in real time, shifting the approach from “reactive repairs” to “proactive prevention.”
One-Stop Full Lifecycle Services
Guided by the service philosophy of “One Partnership, Peace of Mind Throughout,” we provide one-stop solutions covering the entire project lifecycle:
1. One-Stop Solution Design
Based on the actual load curves of retail and commercial facilities, roof conditions, and industry-specific characteristics, we tailor differentiated solar-plus-storage solutions to support customized large-, medium-, and small-scale projects.
2. One-Stop Warranty
We offer a 30-year power output warranty for PV modules and a 5-year warranty for energy storage systems. Equipped with our proprietary BMS, EMS, and cloud platform, our solutions support battery health prediction and proactive alerts, helping to build a more reliable operating environment.
3. One-Stop Service
Five key benefits: easy design, easy procurement, easy installation, easy commissioning and testing, and easy operation and maintenance.
From warehouse-style supermarkets spanning tens of thousands of square meters to mid-sized chain stores, the “Sunny 365” solar-plus-storage supermarket solution offers end-to-end standardized services—from equipment selection and system configuration to intelligent operation and maintenance. This solution will help retail enterprises reduce costs, improve efficiency, and achieve a green transition under the electricity market mechanism, turning every ray of sunlight into profit for the supermarket.
