Not Financial Advice

The calculations provided by solarroicalc.com are estimates for informational purposes only. While we use government-grade data (NREL PVWatts®, EIA), actual solar savings depend on variables we cannot inspect remotely, such as:

• Exact roof azimuth and pitch.
• Local tree growth and shading over time.
• Future changes in utility rate structures (e.g., NEM 3.0 policies).
• Installation cost variances between contractors.
