The 2026 Rooftop Solar Buyer’s Guide: What Thai homeowners should look forAccording to Mr Techatat Buranaaudsawakul, Chairman of the Electrical Engineering Department at the Engineering Institute of Thailand (EIT), rooftop solar should be treated as part of a home’s critical electrical infrastructure, not simply an add-on appliance. “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. For most households, rooftop solar offers a payback period of four to five years, depending on electricity consumption patterns and overall system efficiency. Rooftop solar systems involve high-voltage direct current (DC), which poses fire and electrical risks if not properly designed and installed.
