Investing in a solar energy system can have powerful financial benefits for your home, allowing you to all but eliminate your monthly electric bill.
But with cost-saving incentives and policies varying from state to state, along with electricity prices and installation costs, it can be hard to quantify the specifics of this investment without reaching out to a solar installer for a quote. That's where this blog can help.
In this blog, we'll give you an idea of what you can expect for a solar investment in your state. We share information on the average solar investment for six states on and near the East Coast, giving you insight into 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 2020. They’re real numbers from real people just like you who already installed solar and are enjoying 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. However, the breakdown of your investment could 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 the utility companies, and with batteries to store energy, solar can even be a dependable backup power solution for emergencies.
