With the cost of everything rising across the country, millions of American homeowners are asking themselves whether or not it’s finally worth it to install solar panels.
The answer to this question depends on a ton of factors, like what your utility charges for electricity and where you live. But, for many Americans, solar panels are definitely worth the investment.
Our solar panels cost and savings calculator takes all the guesswork out of figuring out if solar is worth it or not for your specific home. You can either dive straight into our calculator and get an accurate estimate of how much a solar installation can save you, or you can read on to get a closer look at how to determine if solar is worth it for your home.
The solar payback period refers to the amount of time it takes for the electric bill savings from your solar panels to equal the amount you paid for the system. The average payback period for a residential solar system in 2023 is about seven years.
A payback period of seven years equates to a return on investment of approximately 14%. However, this varies greatly by state and even by regions within states.
Once you have generated an accurate payback period, you can compare this to the returns you see on other types of investments:
As you can see, residential solar panels stack up favorably against all of these other investment options - and this is even before we consider the increase in a home’s value caused by the solar panel installation.
Solar panel cost is often measured as the “cost per watt” of solar. This makes it easy to compare the relative value of solar systems of different sizes in terms of the watts of power they can produce.
Our data shows that the average cost of a residential solar system in 2023 is between $2.85 and $3.00 per watt, before the federal tax credit. At that price, a typical 7 kilowatt (kW) home solar system would cost $19,950 and $21,000. The cost would fall to $13,965 to $14,700 after claiming the 30% solar tax credit.
The cost of residential solar panels has dropped dramatically over time. In fact, it has fallen over 70% in the past decade.
To calculate solar panel cost for your home, it is first necessary to calculate how many solar panels are needed to power your home. The number of solar panels you need depends on how much electricity your home uses.
Our calculator can easily determine how many solar panels you need just by using the cost of your most recent electric bill.
Most standard solar panel warranties ensure that your solar panels will last at least 25 years. As solar panels age, their power output decreases. It’s normal for a warranty to guarantee that they will produce over 80% power output at the end of 25 years.
There is very little maintenance required for solar panels. It is recommended that you clean your solar panels once or twice a year to avoid dirt and buildup. However, this might not be necessary if your area gets regular rainfall or if your roof is steep, which allows debris to easily fall off.
It is worth checking to see that all junction boxes are sealed and watertight once every five years.
Because there is almost no maintenance required, you don’t need to worry about additional maintenance costs.
There are a number of factors that determine how suitable your roof is for solar panels, including:
When trying to determine if solar panels are worth it for you, consider the size, direction, pitch, and the amount of shading your roof has. Large, unshaded, southern-facing roofs are the most ideal for solar production.
While solar panels facing due south do produce the most overall electricity, it’s perfectly fine to have panels facing southwest and southeast.
As solar prices continue to fall, panels are being put on west-facing roof spaces even though they produce about 15% less electricity.
This is especially common for those with time-of-use electricity billing, who wish to move their solar generation to later in the afternoon (when their power company charges peak rates) in order to save money on their electricity bills.
It is possible to buy solar panel kits and then organize the installation, permitting, and inspections yourself. Doing this could save you between $2,000 and $3,000 - potentially more.
However, there are some potential pitfalls to install solar yourself. The installation of solar panels is dangerous, as it requires you to do electrical work at great heights. It’s also possible that you could damage the equipment, and it can be very difficult to claim a solar warranty when you install on your own. DIY solar projects typically suit those who are contractors, or those who know a qualified solar electrician to help them out.
If you order a DIY solar kit, you can contact a local solar contractor to assist you if you are not comfortable performing the installation on your own. In some cases, however, installers will charge you more for the installation of a DIY solar kit, making it cost the same amount it would have if you hired an installation company to do all of the work. If this is the case, it might not be worth it to install solar on your home with a DIY kit.
Therefore, if you are considering DIY solar panels, we suggest that you get at least one quote from a full-service solar company that will supply the equipment, perform the installation, and handle permitting.
If you think a DIY solar project is right for you, you can use our solar calculator to find out how many solar panels are right for your home. Then, check out our price comparison of popular DIY solar installation kits of that size. We have prices on hundreds of kits from around 20 different online stores.
There are many ways to rank the best solar panels, including by value, efficiency, and performance. These brands tend to have the best overall solar panels:
The number of solar panels you will need to power your house will depend on two factors:
Our online solar calculator can take your monthly power bill and location to work out how many solar panels you need, as well as the cost based on the prices of solar companies near you.
In short, no.
In most areas, it is not necessary to buy a solar battery when you install solar panels on your roof. This is because most utilities offer some form of net metering, which effectively allows homeowners to sell the excess energy their solar panels produce to the power company, instead of physically storing it in a battery.
Even though battery storage is getting cheaper, it still has a relatively long payback period. For example, the Tesla Powerwall only costs around $11,500, including installation, but it will still take almost 10 years for it to pay for itself.
Another important factor when deciding are solar panels worth it is how high your electricity rates are and whether or not your utility offers retail net metering. Places with high electric rates and full retail net metering are often some of the best places to install solar.
With that said, it may be worth considering installing solar with a battery system if you live in an area that does not offer net metering.

A 2015 study showed that a typical solar panel system added a $15,000 premium to the selling price of a home. They did this by studying comparative sales of similar houses with and without solar panels.
Separately, Zillow released a study in 2019 which concluded that solar panels, on average, added 4.1% to the value of a home, effectively making installing solar panels a worthwhile investment, even if you plan on selling your home in the future.
As you can see, there are many factors that go into determining if solar panels are worth it for your home. The return on a solar investment depends on where you live, your roof’s features, your electric rates, and who installs your panels.
The easiest way to answer the question “are solar panels worth it?” is to use our solar calculator to get an accurate cost and savings estimate tailored to your home and energy usage.
Then you can be on your way to powering your home with clean energy - all while cutting your electric bill.
