How The Estimate Works
Generation Basis
We assume ~4 units per kW per day for Rajasthan (conservative, editable). City factors fine-tune this slightly.
Savings Cap
Estimated savings never exceed your current annual bill — you can't save more than you spend.
CO₂ Factor
Approx. 0.82 kg of CO₂ avoided per unit of solar generation — a commonly used grid average.
