How the Google Project Sunroof Calculator Works

Google Project Sunroof is your very own personalized solar savings estimator, powered by Google Earth imagery.

  • Search for your home. The calculator will use Google Earth imagery to analyze your roof shape and local weather patterns to create a personalized solar savings estimate.

  • Personalize your solar analysis. Adjust your average monthly electric bill to fine-tune your savings estimate and the recommended number of solar panels to offset your home’s energy usage.

  • Find out if your home qualifies for Sign and Shine. The calculator will ask a couple of questions about your home to pre-qualify you for the Sign and Shine solar program.

How Solar Power Saves You Money

Little or No Electric Bill

Depending on how many solar panels you have installed, you could offset your entire electric bill.

Increased Home Values

A Zillow study found that homebuyers will pay 4.1% more, on average, for a home with solar panels.

Tax Incentives & Rebates

Take advantage of a Federal 30% tax credit and other local solar incentives and rebates.

Increasing Utility Rates
