The Finance Ministry's screening board sent back projects that lacked detail under the 400-billion-baht energy-transition loan decree. Rooftop solar for households is the first phase and is expected to be pushed through in September, with first cabinet approvals from October. The reported subsidy is 50,000 baht per household, targeting 1 million homes, about 50,000 million baht in total. Eligibility rules: projects must be urgent, not already budgeted, able to start right after cabinet approval, and use Thai-made materials; work must finish by 30 Sep 2027 and payments by 31 Dec 2027. Consultancy, research, study tours and overseas travel are excluded. Solar installers and EV-related suppliers should prepare Thai-made product lines and compliance documents now; the subsidy details are not final.
