The Energy Ministry is pushing a 1-million-roof solar scheme: a subsidy of about 50,000 baht per household, soft loans at 2-4% a year from state banks (Krungthai-style On-bill Financing via GSB and GHB), and repayments taken from the electricity bill savings. Rooftop permits are to be cut to 7 days, and grid sell-back approval to 30 days. The design is still pending, due in about a month. For a business with a roof, this is worth checking once the terms are published; the 500 MW public buy-back quota is already open. Note: the article describes household schemes, and does not confirm terms for commercial premises.
