The demand for solar rooftop systems in India is at an all-time high in 2025, as more households and businesses realize the long-term financial and environmental benefits of switching to solar. One of the most common questions people ask is, What is the cost of installing a solar rooftop system in 2025?
The overall cost depends on factors such as system size, panel quality, inverter type, and whether batteries are included. On average, a 1 kW solar rooftop system in 2025 costs between ₹65,000 to ₹75,000 without subsidies. This system typically generates 4–5 units of electricity per day, sufficient for small households.
For medium households, a 3–5 kW system may cost between ₹2,00,000 to ₹3,50,000, while larger homes or commercial spaces opting for 10 kW or more could see investments of ₹6,00,000 and above.
The good news is that the Government of India continues to provide subsidies under rooftop solar programs. In 2025, residential users can avail up to 40% subsidy on systems up to 3 kW and a fixed subsidy for larger installations, significantly lowering upfront costs.
Another factor to consider is whether you choose an on-grid or hybrid system. On-grid systems are more affordable, while hybrid systems with batteries cost more but provide backup during power cuts.
Though the initial investment may seem high, the payback period is only 4–6 years due to massive savings on electricity bills. With a lifespan of 25 years, solar panels deliver free electricity for decades after breakeven.
In conclusion, the cost of installing a solar rooftop system in 2025 is not just an expense but a long-term investment in energy savings, sustainability, and independence.
