The Interior Ministry, PEA, MEA and state banks agreed on 30 Sept 2569 (2026) to extend the household solar scheme beyond rooftops to On-ground and Floating Solar. Grant: 50,000 baht per household for systems of 5–10 kW. Loans via GSB, BAAC and GHB at about 2.5% a year over 7 years. Target 1 million households, with registration expected from 1 Nov 2569 (2026). Only up to 5 kW can be sold back to the grid, at 2.20 baht/unit for about 20 years. Installers must be certified and registered as PEA/MEA vendors. Using sale income to repay bank loans is still under review, due in October. Check your power bill first: the scheme only pays off at roughly 3,000–4,000 baht a month or more.
