Thailand to Enforce New Solar Panel Standards by September

According to a report by Thai Post on August 19, 2026, Minister of Industry Varawut Silpa-archa has instructed the Thai Industrial Standards Institute (TISI) to accelerate the issuance of TISI certifications for solar panel operators. This directive comes as the government prepares to implement new mandatory standards for solar equipment before the end of September.

To facilitate this transition, the Ministry is implementing measures to streamline the application process. Notably, authorities have agreed to accept international test results based on International Electrotechnical Commission (IEC) standards, which is intended to reduce administrative burdens for businesses and ensure a smoother rollout of the new requirements.

For residents and property owners in Thailand, this development is significant as it aims to ensure the quality and safety of solar energy systems being installed across the country. By standardizing the equipment, the government seeks to improve the reliability of renewable energy infrastructure. However, it remains to be confirmed how these new standards will specifically impact the pricing of solar panels for consumers or if there will be a grace period for existing installations that do not meet the new criteria. Further updates from the Ministry of Industry are expected as the September deadline approaches.
