How This Works

1

Total System Cost = System Size (kW) × 1000 × Cost per Watt. This includes panels, inverter, racking, labor, and permits.

2

Energy Production = System Size × Peak Sun Hours × 365 × 0.8 (system losses). Accounts for inverter efficiency, shading, and wiring losses.

3

Net Savings (25 yr) = Cumulative bill savings (with annual 3% utility escalation) minus total system cost. Includes 30% federal tax credit.
