Warning: Non-Certified Solar Panels Increase Fire Risk

Warning: Non-Certified Solar Panels Increase Fire Risk

As Thailand continues to promote clean and renewable energy, solar power has become an increasingly popular choice for both households and businesses. Solar rooftop systems are now widely adopted as a way to reduce electricity costs while supporting national efforts to lower greenhouse gas emissions and strengthen long-term energy security. However, along with this rapid growth comes an important safety concern that should not be overlooked: the risk of fire caused by non-certified solar panels.

The Minister of Industry, Ms. Pimphattra Wichaikul, has emphasized that while the government strongly supports the use of renewable energy, public safety must remain a top priority. Recent incidents shared online have shown cases of solar panel fires, raising concerns about the quality of equipment and installation standards used in some projects. These incidents serve as a clear reminder that choosing uncertified solar panels and improper installation methods can lead to serious hazards.

Why Non-Standard Solar Panels Are Dangerous

Solar panels are designed to generate and transmit electrical current to power appliances in homes, factories, and commercial buildings. When multiple panels are connected together, electricity flows continuously through the system. If one panel has internal defects or fails to meet safety standards, it can disrupt the flow of electricity.

According to the Thai Industrial Standards Institute (TISI), one of the main causes of solar panel fires is abnormal electrical resistance. When electricity cannot flow smoothly—often due to poor-quality materials or defective components—electrical current from multiple panels may concentrate at a single point. This causes excessive heat buildup, which can exceed the panel’s thermal tolerance and eventually ignite a fire. Once a panel catches fire, flames can easily spread to adjacent panels and nearby structures.

This risk is significantly higher when panels have not been tested or certified according to recognized safety standards.

The Importance of TISI (TIS) Certification

To protect consumers, TISI has established voluntary national standards for solar panels that focus on both performance and safety. These standards ensure that panels are suitable for real-world operating conditions and can withstand heat, electrical stress, and environmental exposure.

The two key TISI standards for solar panels include:

• TIS 61215 Part 1 (1) – 2018, which evaluates panel performance and power generation efficiency
  
  
• TIS 2580 Part 2 – 2019, which focuses on safety requirements such as heat resistance, fire prevention, electrical insulation, leakage protection, and operation under high temperatures
  
  

Panels certified under these standards have undergone rigorous testing to reduce the risk of overheating, electrical faults, and fire propagation. They are also designed to remain stable even when partially shaded by clouds, leaves, dust, or debris—conditions that commonly occur during normal operation.

Installation Quality Matters Just as Much

Even certified solar panels can become hazardous if they are installed incorrectly. Poor wiring, improper connections, or non-standard mounting methods can all increase fire risk. That is why professional installation by trained and experienced technicians is essential.

Certified installers understand how to design electrical layouts that prevent current overload, ensure proper grounding, and allow for safe heat dissipation. This combination of certified equipment and professional installation is the foundation of a safe and reliable solar system.

Choosing Certified Manufacturers for Peace of Mind

Currently, only a limited number of manufacturers in Thailand have received official certification from TISI for both performance and safety standards. These manufacturers have demonstrated their commitment to quality, safety, and compliance with national regulations.

Solar PPM Co., Ltd. is among the certified domestic manufacturers that have been granted licenses for both TIS 61215 and TIS 2580 standards. This certification reflects the company’s adherence to strict quality control, material selection, and safety testing processes.

For consumers, selecting solar panels with visible certification marks is one of the simplest and most effective ways to reduce fire risk and ensure long-term system reliability.

A Smart Investment Starts with Safety

Solar energy is a valuable investment that offers long-term savings and environmental benefits. However, cutting corners on equipment quality or installation standards can result in costly damage, safety hazards, and loss of trust.

Before installing a solar system, consumers should always verify that the panels meet recognized standards, are supplied by certified manufacturers, and are installed by qualified professionals. These precautions not only protect property and lives but also ensure that solar energy remains a safe and sustainable solution for Thailand’s future.

By choosing certified solar panels and responsible installers, solar power can truly deliver clean energy without compromising safety.
