Calculate solar panel system cost, monthly savings, and payback period. Compare solar installation costs vs current electricity bills.
How it works: This calculator estimates the total solar investment cost, monthly generation, annual savings, and payback period. It accounts for inverter efficiency and panel degradation. Results help you understand if solar is financially viable for your property. Actual results depend on local sunlight, weather, and installation quality.
Divide your monthly electricity bill by ₹1000. For example, ₹3000 bill needs ~3 kW system. A 1 kW system typically generates 120-150 units/month depending on location. Use this calculator to test different sizes.
Typically 5-8 years in India with current subsidy and panel costs. After payback, you get free electricity for 20+ years (panel lifespan). This calculator shows your specific payback period.
Costs vary: ₹70-120 per watt installed (residential). Use ₹100/watt as average estimate. Prices keep decreasing; check local solar providers for current rates. Government subsidies may reduce your cost further.
Yes! Solar panels lose 0.5-0.7% efficiency yearly. After 25 years, panels still perform at ~80% capacity. This calculator accounts for degradation in its projections.
For most homes with monthly bills above ₹2500, solar ROI is positive. Additional benefits: energy independence, government incentives, tax benefits, property value increase. Use this calculator plus local quotes to decide.
