What is a payback period for residential solar energy?

For most homeowners in the United States, it takes about eight years to reach the breakeven point of an investment in a solar panel. For example, if the cost of your solar installation is $ 16,000 and the system helps you save $ 2,000 per year on your energy bills, your payback period will be approximately eight years (16,000/2 000 = 8).

To put it a little differently, the solar payback is the time it will take for your utility savings to eclipse your initial capital cost. This is where you could say the solar panel system has “paid for itself”.

Keep in mind that there are a number of basic determinants that go into calculating solar payback periods, including installation costs, interest rates if you take out a solar loan, credits applicable solar tax and rebates; and energy bill savings. The latter will always be relative to the electricity costs in your area, so areas that have higher utility costs tend to have slightly shorter payback periods.

Average payback period for solar panels in the United States

Although the average payback period for solar panels is between eight and 12 years, it can vary widely from house to house. For some, it can be as little as five years. For others, it can be up to 15 years. Local electricity costs and state-specific financial incentives, such as tax credits, solar rebates or net metering programs, are determining factors.

What is considered a good payback period for solar panels?

One way to determine if you are getting a good return on your solar energy investment is to look at the life of your system. Most residential solar systems last between 25 and 30 years. If your payback is eight years, you will “make money” on the system for 17 to 23 years.

Most solar industry experts say that if your solar panel’s payback period is less than half the life of your system, it’s a decent investment.

Another thing to keep in mind is the internal rate of return, or IRR. Basically, think about what would happen if, instead of investing in solar power, you put your money into a more traditional financial investment. How effective should this investment be for it to be more financially beneficial than a solar system?

Depending on your investment strategies, solar panel installations may or may not offer a higher return on investment than buying stocks, real estate, or other investments. It is important to carefully weigh the IRR to ensure the most prudent decision.

How to calculate your solar payback period

While it’s impossible to calculate the exact payback period for your solar panels, getting a quote from an installer will allow you to make a fairly accurate and well-informed estimate.

Here’s how to do it:

  1. Calculate or get a quote for the total cost of your system. Talk to a solar installer near you to determine the gross up-front cost of your system. Note that this will depend on the size of the system as well as the type of equipment you need and additions like solar battery storage.
  2. Take into account the federal tax credit and any applicable local discounts or credits. These financial incentives can significantly reduce your solar expenses. In particular, the federal tax credit allows you to deduct 26% of the total cost of the facility on your tax return. It goes beyond any specific state or city incentives. Don’t forget the Renewable Solar Energy Certificates (SRECs) from net metering programs.
  3. If you are funding solar panels, consider the associated additional fees or costs. If you are taking out a solar loan to pay for your system, you will need to factor in all of the other expenses associated with the loan.
  4. Calculate your average annual electricity consumption and costs to determine how much you will save on energy by switching to solar power. Solar installers will do their best to create a system that matches your electrical usage, but there are a lot of variables to consider, including seasonal changes. Even so, knowing how much you spend on electricity each year can give you a good idea of ​​your potential savings.
  5. Take into account the rate of increase. When calculating the cost of electricity, keep in mind that local rates can increase over time. You can always call your utility company and inquire about planned increases, or look at bills from previous years to determine previous rate increases.
  6. Divide the cost of the system (including financial incentives) by the annual amount you will save on electric bills. This will tell you approximately how many years it will take you to recoup your initial investment. Beyond that, each month that you run your solar system can be considered a financial gain.
