The Interior Ministry is considering raising the rooftop solar subsidy from 1 million to 1.5 million households, at 50,000 baht per household (about 75,000 million baht total). Details go to the Finance Ministry by 11 September, with registration expected mid-October. The proposal is not yet final. State banks (Krungsri-style lenders GSB, GHB and BAAC) would offer loans, and EGAT-linked buyback of household power is planned, with an estimated 1,000 baht a month for a 5 kW system. Installers and solar suppliers should watch for demand from this scheme, and Thai factories may get import-duty relief for locally made panels.
