The Thai Cabinet relaxed regulations on solar rooftop installations with the introduction of the Ministerial Regulation Re: Designation of Type, Kind, and Size of Factories (No. 3), B.E. 2567 (2024) (the “Ministerial Regulation”). The Ministerial Regulation does away with the need to obtain a factory license from the Energy Regulatory Commission (ERC) or Department of Industrial Works (DIW) for all solar rooftop power generation installations located outside of industrial estates, irrespective of their production capacity. This relaxation came into effect on December 28, 2024.
Previously, the installation of such solar rooftops with a generating capacity exceeding 1,000 kW required a factory license. This move specifically targets solar power generation installations located on rooftops, terraces, or any part of buildings that can be occupied or used. It is noted that solar ground mounted and floating projects are not affected by the Ministerial Regulation.
