China's solar and storage sectors saw several major developments in late June 2026. CATL and CECEP expanded their partnership to include perovskite PV, sodium-ion storage, carbon-neutral island projects in Hainan, and green mining overseas. Separately, Trina Storage filed plans for a 36 GWh lithium-ion battery factory in Chuzhou, Anhui, with a total investment of RMB 7.2 billion. On the deployment side, China added only 8.68 GW of new solar PV in May 2026, a 90.65% year-over-year drop. Cumulative solar capacity reached 1.26 TW. The NDRC and NEA also released the 15th Five-Year Plan for a new energy system, targeting non-fossil energy at 25% of consumption, wind and solar exceeding 50% of generation, and 300 GW of new energy storage by 2030. These numbers set a clear direction for grid decarbonization and storage buildout in the world's largest renewables market.
