Solar Energy is the fastest-growing electricity source and is expected to contribute 36 percent of total US renewable energy generation by 2050. Shifting to solar has a wide range of economic, environmental and personal benefits.

But let's admit it . The process of going solar has always been confusing! 

Even though homeowners agree with the benefits of a solar panel system (tens of thousands in energy bill savings), they are often bothered with many questions and doubts, particularly around the cost of solar.

Introducing... Our Brand New Solar Calculator!

To clear this confusion and to help homeowners to decide the best solar panel systems for their homes, Pick My Solar recently upgraded its solar savings estimator (try it out for yourself!).

We now consider it the most sophisticated solar panel savings calculator available to homeowners for an instant estimate of their savings with solar. 

Solar system calculators are a great way to begin exploring solar for your home, without needing to commit to speaking with project managers or company representatives.

By providing your address, our solar energy savings calculator helps you to find answers to questions like:

  • What would be my estimated electricity bill after going solar?
  • What are my savings on a solar panel system?
  • What should be the size of my system?
  • What panels makes sense to 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 more accurate cost and savings estimates by analyzing your current electricity bills, rooftop, and solar pricing in your area.

First and foremost, Pick My Solar's calculator is the first-ever to deploy Google's Project Sunroof API to instantly deliver solar estimates on a roof-by-roof basis to users.

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.

This analyzed information is then combined to create an estimate for how much power a user could produce and can save with solar.

Pick My Solar has substantially upgraded its solar savings calculator to provide more accurate cost and savings estimates with solar.

Using our tool, you can see:
