Thailand could soon offer support for home solar aimed at as many as 1 million households, The Thaiger reported.
The proposal would provide up to 50,000 baht ($1,483) toward installing solar panels and, if approved by the country’s cabinet, could also let households make money from electricity they do not use.
The program cleared a government screening committee with a proposed 50 billion baht ($1.5 billion) budget. Each household could claim the subsidy once.
Finance Ministry Permanent Secretary Lawaron Sangsanit said Tuesday that the committee had approved the proposal, per The Thaiger. The proposal is scheduled for review Monday, and registration could open in mid-November.
Households could install solar panels on rooftops or the ground. They would be able to use the electricity and receive payment for surplus power sent into the distribution network.
Officials have not released eligibility rules, but applicants would likely need an electricity account or a registered meter, according to The Thaiger.

A 5-kilowatt system could bring in 1,000 baht ($29.65) a month by selling unused power back to the grid, officials said. That income could help offset installation costs.
Households could also lower their electricity bills.
The budget would be drawn from the energy transition share of the government’s broader 200 billion baht ($5.9 billion) borrowing plan, The Thaiger noted. At 50 billion baht, the solar subsidy would take up one-quarter of that pool.
The proposal builds on an existing framework that lets households sell extra solar electricity. Under the Metropolitan Electricity Authority’s buy-back arrangement, excess power can be sold at 2.20 baht ($0.07) per unit over a 10-year term, and the Provincial Electricity Authority is also part of the wider sell-back system.
In addition to the subsidy, the government is seeking financing options for households whose installation costs exceed the 50,000 baht cap. State-owned lenders expected to take part include the Government Savings Bank, Government Housing Bank, and the agricultural co-op lender.
Daily News reported, per The Thaiger, that one proposed loan option would charge 2.5% interest across a seven-year term with no collateral required, which could help households cover costs beyond the 50,000 baht cap.
Officials are also considering a repayment approach tied to solar income. Under that idea, money earned from selling surplus electricity back to the grid could go toward loan repayments.
Thailand’s proposed subsidy is part of a wider effort to make rooftop solar easier for households to afford.
• In Thailand and the Philippines, rooftop solar booms followed fuel-price shocks and rising grid costs.
• In Australia, a homeowner’s 20kW solar setup delivered blackout resilience and a $545 monthly credit.
• In North Lincolnshire, a free solar panel scheme cut energy bills.
• In the United States, solar panel subscriptions are lowering upfront costs for rooftop power.
