Thailand's Ministry of Interior has submitted a 750 billion baht budget proposal to install rooftop solar panels on 1.5 million households (increased from an initial 1 million target), with 50,000 baht subsidy per household. The project has cleared the initial screening committee and awaits Cabinet consideration. Officials deny vendor lock-in concerns, noting 2,300+ registered installation companies are available; the state-run utilities (MEA and PEA) will handle ~300,000–400,000 installations directly while contracting private firms for the remainder. Installation requires smart meters and two-way grid connections before subsidies are paid out.
