MOE Subsidies for Self-Consumption Solar and Batteries: FY2026 Rounds Closed, Prepare for the NextA program where the government helps pay for solar and batteries on company roofs and parking lots
The Ministry of the Environment runs a subsidy project (the project to promote price reductions of solar power equipment toward storage parity) that supports installing self-consumption solar and storage batteries together at factories and facilities. Applications were accepted from April 9 to May 15 and from August 27 to October 2, 2026, and both have closed. Menus for parking lots, farmland and water surfaces, and perovskite also exist.The Ministry of the Environment has a program that helps pay part of the cost when a company or factory installs solar panels to make its own electricity and batteries to store it. The FY2026 application periods are already over, but knowing what exists will help next time.
