Solar Savings Calculator

How It Works

Enter your monthly electric bill, usable roof area, and average peak sun hours for your location. The calculator sizes an appropriate solar system, estimates annual energy production and savings, factors in the 30% federal tax credit, and projects your payback period and 25-year savings.

Solar Tips

• South-facing roofs (in the Northern Hemisphere) produce the most energy
• Check your state and local incentives - many stack on top of the federal credit
• Solar panels typically last 25-30 years with minimal maintenance
• Get quotes from at least 3 installers and compare cost per watt

About This Tool

This solar savings estimator provides a simplified projection based on system size, sun exposure, and current electricity rates ($0.12/kWh average). Actual savings depend on your utility's net metering policy, panel efficiency, roof angle, shading, and local electricity rates. Always get a professional site assessment.
