Thai Finance Ministry Clarifies Residential Solar Program Regulations
The Permanent Secretary of the Ministry of Finance has addressed concerns regarding the residential solar power program, emphasizing that the current criteria are designed to prevent favoritism toward large corporations.
According to a report by Thai Post on October 28, 2026, the Permanent Secretary of the Ministry of Finance has publicly defended the government's residential solar power initiative. Addressing concerns that the program might disproportionately benefit large-scale operators, the official clarified that the current regulatory framework is structured to ensure fair competition.
Central to this initiative is the liberalization of the vendor market. By allowing various service providers to compete, the government aims to keep installation costs accessible for households. Specifically, the Ministry has indicated that the installation cost for a 5kW solar system should not exceed 140,000 THB.
For residents and property owners in Thailand, this clarification is significant as it suggests a push toward more affordable renewable energy adoption. By capping costs and encouraging vendor competition, the government hopes to make solar energy a viable option for a broader segment of the population.
However, several details remain to be confirmed. While the Ministry has set a price benchmark, it is not yet clear how the government will monitor individual vendors to ensure compliance with these price caps across different regions. Furthermore, potential applicants should wait for official guidelines on how to select certified vendors to ensure their installations qualify for any associated government incentives or grid-connection benefits.
