Government Subsidies in India
India’s PM Surya Ghar scheme provides a fixed ₹78,000 subsidy for systems up to 10kW, reducing net costs to around ₹2,24,825 for a 5kW on-grid setup. Eligibility requires net metering approval and DISCOM registration. Subsidies exclude batteries, so off-grid systems see less relief.
