Solar Calculator

SunMath has been helping consumers figure out if it makes financial sense to go solar since 2009. We take great pride in the accuracy and completeness of our highly customized reports. We know that detailed analysis is critical since a single variable can be the difference between a 5 and 25 year payback.

Not only is our solar calculator accurate, but it is designed on an unbiased, 3rd party platform. Unlike other online solar calculator providers, SunMath doesn’t make any money if you choose to go solar. SunMath doesn’t provide leads to solar installers and we never accepts finders fees. Our #1 goal is to provide valuable, easy-to-use tools so you keep coming back!

The SunMath solar calculator uses monthly cash flows and takes these variables into account:

  1. Geography
  2. System Size
  3. Orientation
  4. Tilt
  5. Installation Date
  6. Cost
  7. Expected Life
  8. Utility Rate Plan (Rate & Structure)
