Bangkok: The Ministry of Industry is taking decisive steps to regulate solar panel standards, with enforcement set to commence by September 2026.
According to Thai News Agency, the ministry is accelerating the announcement of controlled product standards and promoting the recycling of solar panels and batteries, in response to the growing popularity of solar energy.
Mr. Varawut Silpa-archa, Minister of Industry, disclosed that the Thai Industrial Standards Institute (TISI) is preparing to propose adding four standards related to solar cells to the list of controlled products. These include circuit breakers for direct current, fuses for solar power systems, electrical cables for solar power systems, and lithium batteries for energy storage. These standards are expected to be enforced by 2026 as part of measures to support the use of Thai Industrial Standards (TIS) for renewable energy products.
In addition, two new standards are in preparation: solar cell wiring boxes and DC connectors (MC4 connectors). These draft standards will be submitted to TISI for approval by September 2026, aiming to enhance public confidence in the safety of solar cell installations. This initiative follows the TISI's approval of TISI Standard 61730 Part 2-2567 for solar panels in May 2026. The standards are anticipated to be officially declared as controlled products by September 2026.
Mr. Varawut emphasized the importance of expediting the process, with the law expected to be in force by September 2026. Once implemented, solar panels manufactured, imported, or sold in Thailand must pass testing and be certified according to TISI Standard 61730 Part 2-2567, ensuring high quality and safety, with no risk of fire or harm.
The rapid growth in solar cell installations, driven by government policy to encourage solar energy adoption, is a crucial step for the Ministry of Industry. This policy aims to reduce reliance on fossil fuels, save on electricity costs, mitigate global warming, and ensure national energy security. It is expected to build public confidence in clean energy and elevate the standards of Thailand's renewable energy industry for sustainable growth.
Regarding substandard solar panels, Mr. Varawut stated that installation must be done by licensed technicians. Complaints about substandard products can be filed with the Ministry of Industry 24 hours a day. He urged the public to check for the Thai Industrial Standard (TIS) mark on equipment, ensuring compliance with TIS standards.
With the increased popularity of solar panels, electronic waste from expired panels is a concern. Mr. Varawut noted that within two years, a significant volume of used panels will reach the end of their lifespan, necessitating a focus on recycling. The Ministry of Industry is coordinating with the private sector to develop solar cell recycling industrial parks.
Addressing concerns about Thailand becoming a dumping ground for e-waste, Mr. Varawut stressed the importance of addressing industrial, plastic, and electric vehicle battery waste. The Ministry is promoting the battery recycling industry and tightening regulations on imports. TISI is working with relevant agencies to prevent illegal e-waste imports.
