Thailand’s Cabinet has given the green light to a draft ministerial regulation that would mandate crystalline silicon solar panels to meet the Thai Industrial Standard, the nation’s official standards body, as reported by pv magazine. The proposal, put forward by Thailand’s Ministry of Industry, aims to enforce product quality and safety requirements intended to avert electric shock, leakage, heat buildup and fire, according to a government press release.
Under the plan, solar panel manufacturers and importers would be required to secure a license under the Industrial Product Standards Act, which oversees national standardisation of product quality and safety. Distributors would only be allowed to sell licensed products that satisfy the TIS, a step meant to stop the production or import of substandard solar panels. The regulation would come into force one day after being published in Thailand’s Royal Gazette.
Government ministers have indicated that the new standards will not introduce additional steps, costs or delays for solar panel imports. The Thai Industrial Standards Institute has verified that imported solar products meeting International Electrotechnical Commission standards may have their IEC test results submitted to the institute for TIS registration without any further product inspection or testing. The institute states the process takes no more than five days and that it is preparing to grant 279 import licenses this month for solar panels compliant with IEC standards.
The Ministry of Industry intends to gradually examine relevant standards for other solar energy system components, such as inverters, cables and batteries, before submitting them to the Cabinet in due course as part of efforts to progressively raise the safety standards of solar systems.
The regulation represents the latest in a series of initiatives in Thailand to enhance the safety of solar panel installations. In May, the country’s Office of the Consumer Protection Board launched an investigation into substandard solar system installations after increasing reports of faulty PV equipment, including signs of melting and burning. In August, authorities started officially registering certified solar installations and PV equipment as part of preparations to expand rooftop solar installations in Thailand. The government is currently preparing a two-phase THB 200 billion, or $6 billion, energy transition program, with the first phase targeting rooftop solar deployment covering up to 500,000 households.
Lalida Periswiwatana, Deputy Spokesperson for the Prime Minister’s Office, said that while the government is promoting greater public access to solar energy, the expansion of solar rooftop systems must be coupled with safety measures. She added that panels installed by the public must be of high quality and meet standards so that people can confidently and safely generate their own electricity, reducing their energy costs.
Thailand’s cumulative solar capacity reached 6,842 MW at the end of 2025, according to figures from the International Renewable Energy Agency, compared with 3,388 MW at the end of 2024.
