Sena Development (which also runs a solar installation arm) backs government plans to set stricter standards for solar contractors and installers. Its MD says the "1 million rooftops" solar policy's growth is uncertain because many households fail bank loan applications for systems costing around 100,000 baht, and failed loans can hurt borrowers' credit. She says local-only demand makes pricing hard; scale from a global market would lower panel and inverter costs. For a solar installer or a business selling to homeowners: expect tighter certification rules, and plan for customers who need financing. Sena has verified its own status with PEA and MEA at no cost.
