The Finance Minister says the Interior Ministry will send a rooftop solar programme to the Finance Ministry on or around 11 Sep 2026 to draw on the 200 billion baht energy-transition loan decree. Initial plan: 1 million households at 50,000 baht each (50 billion baht), possibly raised to 1.5 million; start targeted mid-October with runs to end-2027. Households may be able to sell power back via EGAT smart meters, with Government Savings Bank, BAAC and GHB financing installation upfront. Import-tax cuts on some solar components are also being considered. Still a proposal pending board review, so no eligibility or rates are final. If you run a solar installer, electrical or roof-related business, prepare for demand and staffing; if you are a household or shop owner, watch for the October launch details.
