Thailand's government is rolling out a major rooftop solar subsidy targeting 500,000–1 million households with 50,000 baht per-household grants, low-interest financing through state banks, and a net-billing system for surplus electricity. The scheme addresses energy security (Thailand imports 60% of electricity) and offers householders breakeven in 3–4 years with linked loan repayments tied to actual electricity savings. This represents significant opportunity for SMEs in installation, equipment supply, and financial services.
