Investing in a solar power plant in India offers significant savings on electricity bills and contributes to a greener environment. Here's a practical breakdown of what you can realistically expect to save - for homes, businesses, and factories.
Realistic Savings by System Size
Your monthly savings depend on your system size and your current electricity tariff. In UP, where residential rates have risen to ₹7–9/unit in 2026 and commercial rates are ₹9–11/unit:
- 1 kW system: Generates ~120 units/month → saves ₹840–1,080/month
- 3 kW system: Generates ~360 units/month → saves ₹2,520–3,240/month
- 5 kW system: Generates ~600 units/month → saves ₹4,200–5,400/month
- 10 kW system: Generates ~1,200 units/month → saves ₹10,800–13,200/month (commercial)
Initial Investment and Payback Period
After the central government subsidy under PM Surya Ghar Yojana, a 3kW system costs around ₹1,07,000 in 2026 - down from ₹1,32,000 in 2024. At ₹2,900/month in average savings, the payback period is now approximately 3 years. After that, you generate electricity for free for the remaining 22+ years of the system's life.
Long-Term Savings (25-Year Lifetime)
- 1 kW system: Lifetime savings of ₹3–4 lakhs
- 3 kW system: Lifetime savings of ₹8–11 lakhs
- 5 kW system: Lifetime savings of ₹13–18 lakhs
- 10 kW system: Lifetime savings of ₹30–42 lakhs (commercial)
Additional Financial Benefits
- Net metering income: Sell excess electricity back to UPPCL/LESCO
- Property value increase: Solar-equipped homes sell at a premium
- Accelerated depreciation: 40% in Year 1 for businesses (Income Tax Act)
- Inflation hedge: Electricity rates increase ~5% annually; your solar cost is fixed
Maintenance Costs
Solar systems require very little maintenance - mainly periodic panel cleaning (2–4 times/year) and an inverter check annually. Total annual maintenance cost is typically ₹3,000–₹8,000, which is a fraction of your savings.
