Before installing a residential solar system, you may stop to wonder: Do solar panels increase home value? It turns out, the answer is a resounding yes.
We'll go over how much solar panels can increase the value of your home, as well as how that increased value affects property taxes and whether buyers are really looking for homes with solar energy systems. With this knowledge, you can make an informed decision about whether solar panels are a good investment for your home.
How Much Do Solar Panels Increase Home Value?
Many homeowners, buyers, and appraisers know that the installation of solar panels and solar batteries can increase a property's market value. In fact, one study confirmed that solar installations increase a home's resale value by up to $5,911 for each kilowatt of solar panels installed, and another estimated an increase of 4.1% of the home's value.
Where do these figures come from, exactly? To begin with, consider a Zillow study, which notes that homes with solar installations tend to sell for about 4.1% more than homes without. Of course, this is an average. Some locations show a higher value-add (5.4% for New York City), and some show lower (2.7% for Riverside, California). An older study from Lawrence Berkeley National Laboratory reveals an increase in resale value of approximately $5,911 for each kilowatt of solar power that's installed.
So, how much do solar panels increase home value? Let's take a look at some averages:

It's worth noting that these amounts are roughly in line with the total cost of a solar panel system, which may be just the incentive you need to finally take the plunge into solar power.
Factors That Influence the Value-Add of Solar Panels
While these simple calculations can give you a ballpark, there are a number of factors that influence the value-add of solar panels. Some of the most prominent include:
Geographic location: Different communities experience different electrical costs (and higher electrical costs result in greater value from your solar panels). Additionally, geography can influence the amount of sun exposure you get, as well as the social benefits of installing solar power.
Local solar installation prices: Another geographic factor is the cost of getting a new system in your area. If a buyer would save money by purchasing a home with a system already installed, it will make your home that much more valuable.
System output: As you can see from the chart above, a larger system with more energy generation will provide more added value.
System age: If you have an older solar system, you'll need to account for depreciation. Older systems won't add that much value to your home when you sell it, as there's a higher chance the buyer will need to do repairs or replace parts sooner.
System replacement value: Along the same lines as system age, how expensive or difficult parts of your system would be to replace affects the added value of the system overall.
Are Buyers Looking for Homes with Solar Panels?
Another question to consider when figuring how much solar panels would increase your home value is just how enticing a solar system is to buyers in your community. This is something that will vary by geography, and specifically by local solar literacy. Simply put, buyers won't be as willing to invest in a solar system if they don't really understand how solar panels work or how they can benefit from them.
With that said, there's some data that shows homeowners to be pretty open to energy efficiency features, for the most part. For example, more than 80% of homebuyers say that energy efficiency is a priority, according to the Zillow Group Consumer Housing Trends Report.
Some earlier data from the National Renewable Energy Laboratory shows that homes with solar panels sell 20% faster and for 17% more than those without. (Granted, this information is about 15 years old; there's now greater supply and greater demand for homes with solar panels, but these data points should be promising nonetheless.)
How Do Solar Panels Affect Property Taxes?
Of course, when your property values go up, that usually means that your property taxes increase as well. The good news is that many states offer exemptions, meaning that when you install a solar system, your property taxes do not go up, even if your property value rises.
Here's a rundown of property tax exemptions by state:
