Thailand's Public Debt Management Office is adjusting its Solar Rooftop subsidy programme to lower the system size from 5 kW to 3 kW and reduce the subsidy from 50,000 to 30,000–50,000 baht per household. The change aims to include smaller-home owners who cannot justify 5 kW systems (requiring 3,000+ baht/month electricity consumption). The 1-million-household target may also be revised. A subcommittee will meet soon to finalize details before the 30 September 2026 project submission deadline under the 400-billion-baht energy crisis emergency decree.
