Payback and ROI of Solar Energy for Homeowners

Solar Energy payback and ROI for homeowners

Investing in a solar energy system can have powerful financial benefits for your family, putting you in control of a rising expense.


With cost-saving incentives, rising electricity prices, and varying installation costs, it can be hard to quantify the specifics of this investment without reaching out to a solar installer for a quote.
But to help give you a ballpark idea of what to expect, we created this blog.


We compiled the data from all the solar energy installations we completed in the last year to give you the average system size, return on investment (ROI), payback period, price per watt, and environmental impact.

How We Made our Calculations

The statistics shared in this blog are based on the average of all residential solar systems we installed in a particular state in 2021 and the first half of 2022. They’re real numbers from people who enjoy the cost- and emissions-free electricity their systems generate.

It’s important to note that people’s incentives for going solar vary greatly, as do the ROIs, payback periods, system size, and more. These numbers are just averages and are meant to give you a broad idea of what you can expect. The breakdown of your investment will likely look very different from the average for your state.

Is Solar a Good Investment for Homeowners?

While trends can be seen from state to state, the value behind each solar system is highly specific to each home. The more electricity your home uses, the higher your cost of electricity, and the more cost-saving incentives available to you, the better your investment will be. 

That said, solar offers significant benefits that go beyond saving you money each month. Every solar system can have a positive impact on the environment. It will also provide a level of energy independence from utility companies, and with batteries to store energy, solar can even be a dependable backup power solution for emergencies.
