The government is preparing a 75 billion baht household solar scheme for 1.5 million homes, in two phases (50 billion, then 25 billion). It offers a 50,000 baht installation subsidy, a 10kW system cap, and surplus power sold to Egat at 2.20 baht per unit under a 20-year contract. Loans from GH Bank, GSB and BAAC carry 2.5% interest over about seven years. This is still a proposal, so eligibility and timing are not final. If you run a shop, farm or home-based business with a meter and suitable roof, space or pond, start checking the numbers now. Note that the article says the buyback limit is 5kW, while the system cap is 10kW.
