Solar Calculator: Estimate Your Solar Savings

Why Use a Solar Calculator?

At the end of the day, going solar is an investment. Our solar calculator can help you answer the two most important questions for any investment:

  1. What’s the upfront cost?
  2. What’s the return on investment?

The interactive solar savings calculator on can help you answer both questions in a matter of seconds. It has been recently upgraded to provide you with the most accurate assessment of your energy costs before and after going solar.

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?

Solar Calculator Instant Estimates

In short, you can instantly calculate your solar savings.

As the first solar calculator  deploy Google’s Project Sunroof, we’re able to provide accurate cost and savings estimates by analyzing your current electricity bill, rooftop, and the solar pricing in your area.

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.

Our solar calculator features:

Improved Shade Analysis

Powered by Google Sunroof data, all cost estimates consider the shading and irradiance levels of every roof plane, with the panel placement optimized for the most productive roof areas.

Available Incentives

Find the value of local rebates and incentives you can claim by going solar. This includes the 30% Federal Solar Tax Credit and local, state, and utility rebates in your area.

If you choose to get customized, binding solar offers through, an Energy Advisor will help you apply these incentives and increase your overall savings.

Payback Period

Instantly understand how many years it will take for your solar system to pay for itself in utility bill savings.

One way to think about going solar is that you’re replacing your electricity bill with payments on your solar equipment. And once that equipment is paid off, you’re paying for neither! That often leaves solar owners with decades of zero electricity costs and tens of thousands in return on investment.

Lifetime Savings

Our calculator will show how much you could save over 20 years of owning solar panels versus paying for grid energy (which tends to increase in price over time). Given today’s panels are typically warrantied for 25 years, you may be able to save even more.
