Understanding Your Solar ROI
How is the System Size Calculated?
Your recommended solar system size is based on your monthly electricity consumption divided by the average peak sun hours for your state (typically 4–5 hours/day in India). This ensures your system covers approximately 85–90% of your electricity needs.
What Subsidies Are Included?
The calculator includes the PM Surya Ghar Yojana central government subsidy: ₹30,000/kW for first 2kW, ₹18,000/kW for 2–3kW, and ₹9,000/kW above 3kW (maximum ₹78,000). Additional state subsidies may apply depending on your location.
Why is the Payback Period 3–5 Years?
With rising electricity tariffs (6–8% annual increase), the actual savings grow every year while your solar investment cost is fixed. This typically results in payback periods of 3–5 years, after which you enjoy virtually free electricity for 20+ years.
