Thailand Solar Program Cap Increase Announcement
Thailand has raised the national cap for its residential rooftop solar net billing program from 90 MW to 500 MW. The change was approved in April 2026 under the “Solar for the Thai People” / Citizen Solar Rooftop program and is intended to reopen applications after a two-year pause.
Key Details of the Thailand Solar Program Policy
Key details from the updated policy include a buyback rate of 2.20 baht per kilowatt-hour (kWh). The power purchase agreement (PPA) tenor is set at 10 years, with an export limit of likely 5 kW per meter under the new framework and a system size limit of 10 kW per installation.
Projected Demand for the Thailand Solar Program
The increased cap is expected to broaden access for households to engage in solar energy production. An analysis by the Institute for Energy Economics, Japan (IEEFA), suggests that demand under the earlier policy indicates the new 500 MW quota could be reached quickly, possibly by 2026.
Impacts of the Thailand Solar Program on Energy Landscape
These changes align with broader efforts to enhance sustainable energy practices within Thailand, addressing the nation’s dependence on imported fossil fuels and reinforcing strategies for renewable energy development. The prior program was deemed effective, showcasing the potential for further expansion in the renewable sector.
