Bangkok:The government is intensifying safety measures for solar panels by preparing to enforce the Thai Industrial Standard (TIS) for crystalline silicon panels. This initiative aims to prevent electric shock, leakage, heat buildup, and fire, thereby regulating both production and import to build public confidence in installing solar rooftop systems.
According to Thai News Agency, Ms. Lalida Periswiwatana, Deputy Spokesperson for the Prime Minister's Office, disclosed that the Ministry of Industry has presented a draft ministerial regulation to the Cabinet. This regulation mandates compliance with standards for crystalline silicon solar panels, aiming to enhance the quality and safety of solar panels to meet international benchmarks, eliminate substandard products, and support the expansion of solar rooftop installations in both public and private sectors.
The proposed regulation specifies that crystalline silicon solar panels, aside from those integrated into other industrial products, must adhere to the Thai Industrial Standard (TIS) 61730 Part 2-2567. This standard includes essential safety checks such as electrical systems, reverse current, and internal overheating to mitigate risks of electric shock, leakage, heat buildup, and fire. The public can be assured that installed solar panels will be of high quality and meet safety requirements.
Ms. Lalida emphasized that setting these standards aligns with the policy of promoting rooftop solar power generation, enabling citizens to generate their own electricity, reduce reliance on the main grid, and lower energy costs. As solar rooftop installations increase, establishing safety standards for the equipment is crucial.
Manufacturers or importers of solar panels under this regulation must obtain a license per the Industrial Product Standards Act. Distributors must sell licensed products that meet these standards to prevent substandard solar panels from being produced or imported into the country.
The Thai Industrial Standards Institute (TISI) has already collaborated with businesses, with approximately 200 manufacturers and importers expected to comply. Previously, TISI held a public consultation on the draft regulation, collecting feedback from 47 parties, of which 7 fully approved the draft, 24 approved with suggestions, and 16 disapproved. A summary report and impact analysis have been prepared.
Ms. Lalida noted that the Office of the Council of State reviewed the draft to ensure quick implementation for public protection. The Office of the Energy Regulatory Commission highlighted the need for guidelines for imported solar panels or those being installed to avoid negative impacts on law enforcement. The Ministry of Industry will consider and address this feedback.
The regulation will take effect the day after its publication in the Royal Gazette. The objective is to align safety standards with policies promoting clean energy, protecting the public, boosting confidence in solar rooftops, and supporting environmentally friendly energy usage while reducing greenhouse gas emissions in the long term.
