The Energy Ministry says it is backing a plan, tied to a 50-billion-baht emergency decree, to install rooftop solar on 1 million homes. Key mechanism: state banks (GSB, GHB) lend at 2-4% a year, with repayments taken from the monthly electricity bill savings. Approval for rooftop solar is cut to 7 days, and grid sell-back to 30 days. The design is still pending, with a decision expected in about a month. For a business owner, this is a possible route to cut power costs or to sell solar installation and financing services. Wait for the final scheme terms before committing.
