The solar industry is witnessing a surge in innovation, with LONGi breaking the silicon-perovskite tandem cell efficiency record, SKYWORTH Solar launching a massive energy storage project, and SunFlex partnering with Nayuta Space for space solar power.

TL;DR
• LONGi sets 35.5% silicon-perovskite tandem cell efficiency record.
• SKYWORTH Solar starts 300 MW/600 MWh energy storage project in Shanxi Province.
• SunFlex partners with Nayuta Space on rollable perovskite solar sail for satellites.

Summary
The solar industry reports significant efficiency gains and infrastructure expansion, highlighting LONGi’s 35.5% silicon‑perovskite tandem cell record and SKYWORTH Solar’s 300 MW/600 MWh storage project.
• LONGi’s 35.5% efficiency surpasses previous 35.2% record, setting a new world benchmark for crystalline silicon‑perovskite tandem cells.
• SKYWORTH Solar’s 300 MW/600 MWh storage facility will provide peak‑shaving, grid stability, and renewable integration in Shanxi Province.
• China’s 2026‑2028 Energy Conservation and Carbon Reduction Plan targets a 1‑percentage‑point annual increase in non‑fossil energy share, supporting large‑scale storage and microgrid deployment.

LONGi’s record demonstrates the feasibility of industrial‑scale tandem modules, with 31.4% efficiency on a 1,650.4 cm² module and 29.4% on a 16,766 cm² module, both included in the Solar Cell Efficiency Tables: Version 68. These figures indicate a clear trajectory toward commercial viability.

SKYWORTH Solar’s project, developed with POWERCHINA under a financing and EPC model, aims to benchmark energy storage solutions. The 12.5 GWh pipeline and partnership with Joybuy for balcony PV products signal a strategic push toward diversified renewable markets.

China’s action plan promotes PV deployment in coal mining subsidence areas, oil and gas fields, and industrial parks, while encouraging green microgrids that integrate PV, wind, storage, hydrogen, and smart management. The plan also calls for long‑duration storage technologies, inter‑provincial trading, and grid upgrades to support direct green power supply.

As the solar industry continues to evolve, it's exciting to see companies pushing the boundaries of innovation and sustainability.
