Why Use a Solar Calculator?

The solar calculator on Solar.com has been recently upgraded to provide customers with the most accurate instant assessment of potential savings associated with going solar (try it out for yourself).

Solar Calculator Instant Estimates

Our solar energy savings calculator helps you discover:

  • What would be my estimated electricity bill after going solar?
  • What are my electricity savings after installing a solar panel system?
  • What should be the size of my system?
  • What panels make sense for my roof?
  • What are the different government incentives I’m eligible for?

In short, we help you Discover Your Solar Potential!

Our solar savings calculator provides accurate cost and savings estimates by analyzing your current electricity bill, rooftop, and the solar pricing in your area.

Solar.com’s solar calculator is the first ever to deploy Google’s Project Sunroof API to instantly deliver solar estimates on a roof-by-roof basis.

What is Google’s Project Sunroof?

Google has dabbled in the solar market with Project Sunroof since August 2015. Project Sunroof uses Google Earth’s high-resolution imagery to help calculate a roof’s solar energy potential.

Upon entering an address, the tool analyzes factors such as shade, roof orientation, and local weather patterns to calculate how many hours of sunlight hit that roof in a typical year.

The findings are analyzed to estimate how much power a user could produce and how much cost savings are associated with going solar.
