Unveiling Average Annual Solar System Output by State

Determining solar savings and the number of solar panels required relies heavily on understanding the electricity production of each panel on your roof. Factors such as roof shading and daily sunlight hours are crucial in this calculation.

Fortunately, the National Renewable Energy Laboratory (NREL), under the U.S. Department of Energy, has developed a geospatial solar map that provides valuable insights into the total solar resource across the United States. This map illustrates the kilowatt-hours per day achievable per square meter of solar energy. Take a moment to explore the map and discover where your area ranks in terms of solar potential.

While this map is a useful tool, it should not be the sole resource for determining the economic viability of solar for your home. Your potential savings will also depend on utility rates in your area, roof type, sun exposure, and the rebates and incentives available in your region. We recommend using our solar calculator to understand better the potential savings you can achieve.

The SunnyRate Solar Calculator considers various factors specific to your location and provides a more comprehensive estimate of the benefits and cost savings associated with solar energy. We encourage you to confidently leverage the solar map and our solar calculator to embark on your solar journey.
