India is seeing a rapid rise in rooftop solar adoption in 2025, with both metro and tier-2 cities embracing clean energy due to higher electricity prices, climate concerns, and strong government policies. This growth supports the government’s target of 500 GW renewable capacity by 2030.

Why Solar Energy in India is Booming in 2025

The cost to install a 3kW–5kW rooftop solar system in India ranges from ₹1.5–₹3 lakhs, depending on the brand, installer, and location. For example, a 3kW grid-tied system costs around ₹1.8 lakh in Delhi, ₹2.2 lakh in Mumbai, and ₹1.6 lakh in Hyderabad with state subsidy.

Cost of Installing Solar Panels

The PM Surya Ghar Scheme offers up to 40% subsidy on rooftop solar, along with state-specific incentives, zero-interest loans, and net metering that lets you sell excess power to the grid. These benefits can cut upfront costs by ₹60,000 or more, making solar more affordable than ever.

Government Subsidies

A 3kW solar system in India can generate 3600–4200 units annually, saving around ₹30,000–₹45,000 per year, depending on location and tariffs. It needs roughly 10 sq. m per kW, so ensure your rooftop has enough space.

How Much Electricity Can Solar Panels Generate Annually?

– Electricity Grid: ₹6–₹10 per unit (increasing yearly) – Solar Electricity: ₹1.5–₹2 per unit (fixed for 25+ years) – Verdict: Solar is significantly cheaper in the long run, with predictable costs.

Solar vs Traditional Electricity Costs

The good news? Solar panels need minimal upkeep—just regular cleaning every 15–30 days and a yearly check-up. Most brands offer a 25-year panel warranty, 10–12 years on inverters, and annual maintenance costs between ₹1,000–₹3,000.

Maintenance Costs and Warranties

Absolutely. With many banks and NBFCs offering 0–5% interest EMIs, going solar without upfront payment is easier than ever. Your EMI can often match your current electricity bill, making it budget-neutral.
