How Solar Savings Are Calculated
Our solar calculator uses industry-standard formulas and current market data to provide accurate estimates for your solar installation. Here's what we consider:
System Sizing
We calculate the optimal system size based on your monthly electricity usage, available roof space, and local solar irradiance data. The calculator assumes 15% system efficiency loss due to inverters, wiring, and other factors.
Cost Calculations
Total system costs include panels, inverters, mounting equipment, permits, and installation. We apply the current 30% federal solar tax credit and factor in any applicable state incentives.
Savings Analysis
Annual savings are calculated based on your local electricity rates and projected solar production. We account for 0.5% annual panel degradation and 2% annual electricity rate increases.
Important Considerations
This calculator provides estimates based on average conditions. Actual results may vary based on shading, roof condition, local regulations, and specific equipment choices. We recommend getting quotes from certified solar installers for precise calculations.
