Thailand’s cabinet has officially greenlit a 50 billion baht household solar-subsidy program as part of the government’s nationwide push towards a shift to clean energy.
Key Point
The program, designed to help 1 million Thai households cut energy costs and gradually reduce the country’s reliance on imported fuel, comes amid continued geopolitical uncertainty and energy price volatility driven by shockwaves in the Middle East since the beginning of the year.
With this approval, the government will help 1 million households install solar rooftops within the year, according to Minister of Energy Ekanat Promphan. The government will provide 50,000 baht in financial support per household, and the Metropolitan Electricity Authority (MEA) and the Provincial Electricity Authority (PEA), under the Ministry of Interior, will serve as the point of contact to help households with the registration and onboarding process.
The Cabinet has approved 50 billion baht to support the initiative.
With the 50,000 baht subsidy, the government hopes households will transition to solar energy, reduce their energy costs, and eventually become their own electricity producers. Within the plan, households can also sell any surplus power back to the national grid.
On 27 October, Prime Minister Anutin Charnvirakul unveiled the campaign, stressing the importance of energy transition.
“Increasing clean and alternative energy is a core government policy, and something the government must deliver to ensure the country’s energy security. This project turns sunlight into an opportunity for the public: rooftops into power sources, electricity bills into household savings, and energy users into participants in producing clean energy for the country,” says the Prime Minister.
Registration for households officially opened yesterday, 27 October, and will run until 31 January 2027.
What Should Households Consider?
The registration process requires some understanding and details that interested households should consider before applying.
To qualify, applicants must be of Thai nationality with a Thai national ID card. They must also be a Type 1 (residential) electricity user. The scheme excludes homes on temporary meters and condominiums. They must also not have claimed, in full or in part, the personal income tax exemption for solar equipment and installation costs under Royal Decree No. 805 (2026)
Beyond rooftops, the scheme also covers ground-mounted panels and floating solar on ponds or other water, provided installations pass a technical inspection by the electricity authority.
The decision here isn’t about the subsidy alone. Participants must install a 5–10 kWp system, use a registered installer, and complete the grid connection within a set timeframe. Some will also face trade-offs; state welfare cardholders must give up their electricity bill assistance for 20 years.
Households must therefore consider their monthly electricity consumption, weigh it against installation costs, and assess whether they can realistically accommodate a 5–10 kWp system. Ultimately, the transition to solar energy must be worth it in the long run.
The scheme supports the government’s ambition to expand renewable energy and reduce Thailand’s reliance on imported fuels as the country works toward its carbon neutrality pledge by 2050 and net-zero emission goals.
Households are a natural and straightforward starting point, with results such as lower electricity bills that are easy to measure.
