Rooftop Solar Savings Calculator

Estimate rooftop solar production, bill savings, net-metering income and payback time in Bangladesh.

How it is calculated

Monthly production ≈ kWp × peak sun hours × 30 × 0.8 (system losses). Self-used units save your tariff price; exported units earn the net-metering price. Payback = cost ÷ yearly savings.

Results are estimates for planning, not bills. Your utility’s bill is final. For generator hookups use a changeover switch installed by an electrician.
