Solar Panel Savings & Net Metering Calculator

Estimate rooftop solar production in the Philippines, bill savings, net-metering export credits and payback time.

How it is calculated

Monthly production ≈ kW × peak sun hours × 30 × 0.8 (system losses). Self-used kWh save your full retail rate; exported kWh earn your supplier’s Smart Export Guarantee (SEG) rate. Payback = cost ÷ yearly savings.

Results are estimates for planning, not bills or professional advice. For generator hookups use a changeover switch installed by a qualified electrician.
