"Safety is a top priority for rooftop solar," Mr Techatat told the Bangkok Post. "A solar energy system must be designed and installed to the same safety standards as any other electrical system in the house. In 2026, a typical residential rooftop solar system in Thailand is expected to cost between 150,000 and 400,000 baht, depending on capacity, inverter technology, and whether a battery system is included. "Many people misunderstand that EIT standards require AFCI and RSD only for rooftop solar systems larger than 200 kW. All rooftop solar, regardless of capacity, must be equipped with AFCI and RSD safety functions," said Mr Techatat.
