Solar Energy in Goa: Complete 2026 State Guide
Goa has India's lowest domestic electricity tariff (₹4.20/unit) but one of the highest tourism-sector tariffs. Hotels and resorts are heavy adopters of commercial solar, while residential ROI is lower than most states.
Solar Potential in Goa
Goa receives approximately 5.0 peak sun hours per day on average. A 3 kW rooftop solar system in Goa generates approximately 4,654 units per year and can save ₹1,606/month on your electricity bill at the current GEDCL tariff of ₹4.20/unit.
Estimated payback period: ~5.3 years after PM Surya Ghar subsidy. After payback, you get 20+ years of virtually free electricity.
PM Surya Ghar Subsidy in Goa (2026)
Residents of Goa are fully eligible for the central PM Surya Ghar Muft Bijli Yojana:
- Up to 2 kW: ₹30,000/kW (total ₹60,000)
- 2–3 kW: ₹18,000/kW for the extra capacity (total ₹78,000 for 3 kW)
- Above 3 kW: No additional central subsidy, but net metering still applies
State subsidy: No Goa state top-up. Central PM Surya Ghar applies. Goa has the lowest domestic tariff in India (₹4.20/unit) which extends the payback period to 7–8 years, but the system still makes long-term sense given 25-year panel life.
