Grid-Tied Solar System Calculator

Tell us how much you are spending on electricity and we’ll calcalute how much you can save if you get solar
I am claiming the 30% Federal Tax Credit (ends 2019) i

When you install your solar system, 30% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is being phased out by 2022.

Most people are eligible to claim this credit (you must owe federal taxes to be eligible).

Our Solar Panel Calculator allows for quick and easy estimation of cost of solar energy, electricity production, and the potential savings for your wallet.

How to use Solar Calculator


1. Please enter your zip code

Zip code is needed to estimate the amount of peak sun hours for your region. Average peak sun hours vary significantly across the USA and directly affect the effectiveness of solar panels.  While calculating sun hours per day should not be a deciding factor in whether or not going solar is right for you, it is a very important metric to consider.

2. Calculate how much you can save using solar energy

We can immediately calculate your saving if you switch to solar. We will based this calculation on the amount of peak sun hours in your area, the daily number of kilowatts you and your family needs, and the current electric bill. We also provide you with the estimated payback period for the solar power system. 

3. Solar panels system size

You will receive a recommendation for the size of the solar system that will suit your needs. This recommendation is based on factors like the average amount of peak sun hours, the daily energy usage for your household, and the current cost of electricity in your region.
