Custom Solar Calculator with Project Solar

Free Custom AI Solar Quoting Tool

This is the tool that allows us to analyze your roofs sun irradiance potential as well as your electricity usage, local utility rates, and available state and federal incentives, to give you a super accurate quote for going solar on your house. This advanced AI took us nearly a year to complete and is what enables us to cut out the solar sales person and offer the lowest price solar in America.

With just 2 basic questions (address and monthly utility usage), we are able to give a 95% accurate quote on your needed system and that systems price net of available incentives.

This is something that has historically taken a solar sales rep 2 hours to consult with you about, after knocking on your door and getting invited into a sit down. 

We've built a substantially more efficient business model, enabling us to cut the cost of solar by nearly 50% of the national average. 


Our solar calculator is unfortunately, not perfect. The biggest limitation that it has is its inability to determine the max amount of panels that your roof can fit. This is something that we still have to do manually, as there are a lot of subjective analysis that goes into it - i.e. aesthetics and efficient groupings for installation. 

The good news for you however, is that you can simply request a custom site design. This is where we map your house in 3D using advanced design tools. We do this for free upon request, and a team member here in our offices in Lehi, UT, will manually design your home.

How We Built Our Solar Calculator

Despite only asking two data questions (address and usage), we are able to calculate 7 different numbers that are pertinent to a solar quote. We offer numbers on the following...

  1. Total Price 
  2. Financed Price (with 4 different payment term lengths)
  3. Total Value of Incentives
  4. Total Price Net of Incentives & Price Per Watt 
  5. Install Price
  6. Time to Pay Off
  7. Estimated Home Value Increase

To get these numbers, we pull from 3 different government APIs that tell us irradiance, local utility rates, and available incentives. 

The irradiance, or amount of sun that your home gets, enables us to calculate how many panels or how many kWs you would need to offset your usage. 

Your areas local utility rate allows us to calculate your usage in terms of kWh/month. 

The incentives allows our calculator to update in real time based on the changing incentives on a state and federal level. 

The Project Solar calculator is the most robust and accurate solar calculator of its kind, and represents a massive improvement in efficiency for the solar industry.
