Calculate your solar panel payback period, lifetime savings, and ROI based on system size, electricity costs, and incentives.
India — Solar Paradise
3 kW rooftop: ₹1.5-2.5 lakh (after subsidy)। PM Surya Ghar: ₹30,000-78,000 subsidy। Savings: ₹15,000-25,000/year। Payback: 4-6 years। Lifespan: 25 years। After payback: 15-20 years of almost FREE electricity! India gets 300+ sunny days — perfect for solar।
Net Metering
Export excess to grid, get credit on bill। Most states allow net metering। Effective: electricity bill near zero!।
Solar calculator searches spike in spring (March-May) when homeowners start outdoor projects, and again in summer when high electricity bills arrive. The solar industry spends heavily on Google Ads ($5-15 CPC), making this page valuable for AdSense revenue from solar installer ads.
