Calculate Your Solar Panel Savings
Curious how much money you will save by going solar? We can help! Our solar savings calculator uses your address and electric bill to show you a solar array that will meet your household needs, along with ballpark pricing info. This tool gives customized results based on your state’s electricity rates and past installation data for solar projects in Maine, New Hampshire, Massachusetts, and Vermont. Simply fill out the form and see your solar panel savings. Include your name and email if you’d like to hear from our team about how to put solar to work for you!
Due to health considerations of Covid-19, we now offer virtual site visits, where we can analyze your home’s potential for solar without needing to visit your home. We carefully monitor and adhere to the state specific restrictions of Maine, New Hampshire, Vermont, and Massachusetts.
Why Solar Panels Make Sense for a Home
Check out our Why Go Solar? guide for a deep dive into the top reasons to go solar.
Our Solar Calculator comes up with a rough estimate of the number panels you’ll need based on:
- Your monthly electric bill. Our tool takes your monthly electric bill in dollars, and divides it by the current average price for electricity, to get the number of kilowatt-hours of electricity you need each month.
- The production of a solar panel. In our region, 1kw of solar panel array will produce roughly 1,200 kilowatt-hours of electricity each year. The average size of a solar panel in 2021 is 355 watts. If you have a $100/month electric bill and live in Southern Maine, where the average rate for electricity is $0.15 per kilowatt-hour. 100/0.15 = 667 * 12 = 8,000 kilowatt-hours needed each year. 8,000 kWh / 1,200kWh/yr = 6.7kw solar array.
- Technical sizing of a solar panels. To translate the example above of 6.7kw of solar into an installable solar array, our tool does some rounding based on actual solar panel systems. We use pricing pulled from average system sizes installed over the last year. Your actual results may vary. For example, if your roof is not ideally oriented, or you have shade trees in the yard, that will reduce a solar panel’s performance. Using our experience and past years’ install data, we know that 6.7kw solar array will be made up of roughly 19 solar panels (if your home or business offers an ideal location for solar panels. If not, we can use that number to calculate shares in a community solar farm.)
- Your location. Our calculator is designed to give you customized results based on the specific electricity rates in your state. Incorporating data from past installation projects done in Maine, New Hampshire, Vermont, and Massachusetts, we are able to calculate a more accurate number using state specific rates. Rather than direct Maine residents to a Maine solar calculator, New Hampshire residents to a New Hampshire solar calculator, and so forth, we’ve built customization right into our tool for a single seamless experience.
Calculate your financial savings!
Since most of our customers choose to finance their solar panel system, we include that in our solar calculator. Our tool conveniently chooses the most common finance option (15 year 3.99% fixed loan) to give you a rough idea of what it will cost you to finance solar. Still, this is only the beginning of your potential savings! Most of the time our customers pair a solar array with improvements such as a heat pump and heat pump water heater to eliminate fossil fuels in their home, accelerating the return on investment of their solar panel array.
