Thailand Tightens Safety Standards for Solar Rooftop Systems
The Thai Industrial Standards Institute (TISI) is introducing two new mandatory safety standards for solar rooftop components to mitigate fire risks.
On August 18, 2026, the Industrial Product Standards Council (IPSC) approved two new mandatory standards for solar rooftop systems to enhance fire safety. According to Khaosod Online, the decision follows concerns that substandard connectors can overheat, melt, or generate sparks, posing significant fire hazards.
The new standards, which the Thai Industrial Standards Institute (TISI) expects to enforce by December 2026, cover two specific components: DC connectors for photovoltaic systems (rated up to 1,500V and 125A) and low-voltage switchgear assemblies for solar power distribution. These measures are part of a broader national initiative to promote solar energy adoption while ensuring the safety of installations.
For residents and property owners, this development is significant as it aims to reduce the risk of electrical fires associated with solar rooftop setups. While these regulations will mandate higher quality components for new installations, the specific impact on existing systems remains to be clarified by the authorities. Travelers staying in properties with solar installations may benefit from the increased safety oversight, though the implementation timeline and potential requirements for retrofitting older systems are still pending further official guidance.
