Thailand Approves ฿50-Billion Solar Program for 1 Million Households

Thailand has launched a nationwide household solar initiative aimed at helping one million households reduce their electricity bills and generate their own clean energy.

The People’s Solar Initiative was officially launched on October 27, 2026, by Prime Minister Anutin Charnvirakul at Government House in Bangkok. The program provides up to ฿50,000 in support for eligible households installing solar power systems, with a national target of one million homes.

The government says the initiative could reduce household electricity costs by more than ฿24.5 billion annually. Participating households may also be able to sell surplus electricity back to the grid under the program’s rules.

What the Solar Program Provides

The initiative has a total support target of one million households, with up to ฿50,000 per eligible participant toward solar equipment and installation.

The program is designed to help households use the electricity they generate themselves. Any excess electricity may be sold back to the grid, subject to the applicable utility rules and connection requirements.

Thailand’s government has also announced that participating households may seek financing from state-owned banks. Loan approval and terms remain subject to each bank’s own requirements.

Who Is Eligible?

According to the Provincial Electricity Authority (PEA), applicants must meet the program’s eligibility conditions. These include:

Applicants must be Thai citizens.
The electricity account must be classified as a residential household account.
The applicant’s name must match the name of the electricity meter owner.
The solar installation must be between 5 kWp and 10 kWp per meter, subject to program requirements.
Installation must be carried out through the Metropolitan Electricity Authority (MEA), the Provincial Electricity Authority (PEA), or an installer registered with the electricity authorities.
The subsidy may be used only once per eligible applicant during the program.

The subsidy is not an automatic cash payment to every household. It is intended to support qualifying solar equipment and installation costs, and participation is subject to eligibility, available funding, and the program’s technical requirements.

Registration Dates and Official Application Websites

Registration opened on October 27, 2026, and is scheduled to remain open until January 31, 2027. The program is limited to one million households nationwide or until the approved funding is exhausted.

Applicants can check the official registration channels based on their electricity service area:

Applicants should confirm the latest requirements directly with the electricity authority serving their area before purchasing equipment or hiring an installer.

Important Conditions Applicants Should Know

The PEA has outlined several conditions that may affect eligibility. Applicants who have already claimed a separate solar rooftop tax deduction may not qualify for the program subsidy.

Households using the government’s welfare electricity assistance should also review the program’s conditions. PEA states that welfare-card holders may participate, but they would forgo the electricity-bill assistance benefit for 20 years under the published terms.

Applicants must also follow the program’s deadlines for submitting grid-connection applications and completing the required connection process. The authorities have set deadlines in 2027 for these steps.

Can Solar Power Help Households Earn Money?

The program is designed to let households become small-scale electricity producers. Solar panels generate electricity from sunlight, which households can use to reduce the amount of power they purchase from the utility.

When a system generates more electricity than a household consumes, surplus electricity may be sold back to the grid under the program’s applicable rules. The actual savings or earnings will depend on the system’s size, household electricity use, sunlight conditions, and the approved purchase rate.

The government has also announced financing options through participating state-owned banks, including the Government Savings Bank, Government Housing Bank, and Bank for Agriculture and Agricultural Cooperatives. Loan approval is not guaranteed and remains subject to the banks’ requirements.

Thailand’s Broader Clean Energy Push

The People’s Solar Initiative is part of Thailand’s broader effort to strengthen energy security and expand the use of renewable energy.

Officials say the program could help reduce dependence on conventional energy sources, support local installation businesses, and improve household energy affordability. The government has also connected clean-energy development with Thailand’s economic competitiveness and its preparations for possible membership in the Organisation for Economic Co-operation and Development (OECD).

However, the initiative’s actual impact will depend on how many households complete installations, the capacity of registered installers, grid-connection processes, and whether the program’s funding and technical requirements can support its one-million-household target.

What This Means for Households

Thailand’s solar initiative could provide eligible households with a way to reduce electricity expenses while contributing to the country’s clean-energy transition.

Still, the ฿50,000 support is subject to the official program rules. Households should check their eligibility, review the approved installer list, and confirm the terms for grid connection and surplus electricity sales before making financial commitments.
