Thailand Mandates TISI Certification for Solar Equipment
The Ministry of Social Development and Human Security has announced strict enforcement of TISI standards for solar panels and related components to ensure safety and quality.
According to a report by Matichon Online on October 28, 2026, the Thai government is intensifying regulations regarding solar energy equipment. Minister Varawut Silpa-archa has emphasized that all solar panels and their associated components must now carry the Thai Industrial Standard (TISI) mark.
This regulatory move is designed to ensure that solar technology used within the country meets specific safety and quality benchmarks. The government has warned that failure to comply with these standards will result in severe legal consequences, including both imprisonment and significant fines for violators.
For residents and business owners, this development is significant as it impacts the procurement and installation of solar energy systems. Those planning to install or upgrade solar infrastructure should ensure that all equipment purchased is certified to avoid potential legal issues or safety hazards associated with non-compliant products.
While the government has signaled a strict enforcement stance, details regarding the grace period for existing installations or the specific timeline for the full implementation of these penalties remain to be confirmed. Consumers are advised to verify the TISI certification of any solar equipment before purchase to ensure compliance with the new requirements.
