Do Solar Panels Increase Home Appraisal Value?

Owned systems vs. leased systems

An appraisal starts with a simple question: do you own the panels outright, or are they leased or under a power purchase agreement (PPA)? Fannie Mae and Freddie Mac guidelines are clear—owned systems can be included in your home’s appraised value, but leased systems and PPAs cannot.

If you purchased your solar panels with cash or financed them through a loan secured by your home (like a home equity loan or a solar loan recorded as a lien on the property), the system is considered real property. Appraisers can assign value to it just like they would for a renovated kitchen or finished basement. However, if your panels are leased or you’re in a PPA where you pay a third party for the electricity the panels generate, the equipment legally belongs to that company—not you. Appraisers treat leased systems as personal property that must be excluded from the home’s value.

This distinction matters more than most homeowners realize. Even if your leased panels save you hundreds of dollars a month on electricity, the appraiser will note their presence but assign zero dollar value to them in the appraisal report. In fact, the lease obligation itself can sometimes complicate the sale, since the buyer must qualify with the leasing company and agree to assume the contract.

How appraisers calculate the value of owned solar systems

When an appraiser encounters an owned solar system, they have three traditional valuation methods at their disposal: the sales comparison approach, the cost approach, and the income approach. In practice, the sales comparison approach—using recent sales of comparable homes with and without solar—is the most common and often the most reliable.

Here’s the challenge: appraisers need solid comparable sales data. If homes with solar panels in your neighborhood have recently sold for more than similar homes without solar, the appraiser can justify adding value to your property. But if no recent comps exist, or if solar isn’t common in your area, the appraiser may struggle to assign a specific dollar figure. Some appraisers fall back on the cost approach—essentially what you paid for the system, minus depreciation—but this doesn’t always reflect true market value.

Research provides some benchmarks. Studies have found that solar panels can add roughly 4% to a home’s value, with some data suggesting premiums of $5,911 per installed kilowatt. A 6-kilowatt system, for example, might add approximately $35,000 in value under that formula. But real-world appraisals are hyperlocal. In markets where electricity rates are high and solar adoption is strong—think California, Arizona, or parts of the Northeast—the contributory value tends to be higher. In areas where solar is rare or electricity is cheap, the boost may be smaller or harder to document.

One critical detail: appraisers look at system age and remaining warranty life. Most panels come with 25-year performance warranties. A system with 20 years of warranty remaining is worth considerably more than one with only 5 years left, since panels degrade at about 0.5% per year. Documentation is essential—installation records, warranty papers, production history, and maintenance logs all help the appraiser make an informed assessment.

Why leased solar panels don’t add appraised value

Leased solar panels generally do not add any appraised value to your home. This isn’t because the panels don’t work or don’t save you money—it’s because you don’t own them. The leasing company retains legal ownership, and the equipment can theoretically be removed or repossessed if the lease isn’t transferred properly.

From an appraiser’s perspective, leased panels are similar to rented appliances. They’re on the property, they may provide a benefit, but they aren’t part of the real estate itself. In fact, the lease can be viewed as a liability the buyer must assume rather than an asset that enhances the property. Mortgage underwriting guidelines from Fannie Mae, Freddie Mac, FHA, and VA all prohibit including leased or PPA solar systems in the appraised value.

This creates a common frustration for sellers. You may have been paying a lease for years, enjoying lower electric bills, and expecting that investment to pay off when you sell. But unless you buy out the lease before listing—which is sometimes possible, depending on your contract terms—the panels won’t boost your appraisal. Buyers may still value the lower utility costs, and homes with leased solar can still sell well, but that value shows up in buyer interest and negotiation, not in the official appraisal number your lender relies on.

What appraisers look for when valuing solar panels

Appraisers don’t just note that solar panels are present—they dig into specifics. First, they verify ownership. Is the system owned outright, financed as a fixture to the home, leased, or under a PPA? This is the lender’s responsibility to confirm, often through a UCC (Uniform Commercial Code) search that reveals whether the panels are listed as collateral for a personal property loan. If the ownership structure is unclear or if a UCC filing shows the panels as personal property, the appraiser will exclude them from the valuation entirely.

Next, appraisers assess system condition, age, and performance. They’ll look for documentation: when was the system installed, what’s the rated capacity, how much electricity does it generate annually, and what warranties remain in effect? A well-maintained system with complete records is easier to value than one with missing paperwork and unknown production history. Appraisers also check for visible damage, outdated equipment, or signs of deferred maintenance—anything that might reduce the system’s remaining useful life.

Finally, appraisers consider market reaction. Have other homes with solar in the area sold for a premium? If so, how much? This is where local real estate dynamics come into play. In neighborhoods where solar is common and buyers actively seek it out, the contributory value is clearer. In areas where solar is rare, appraisers may assign little or no added value simply because there’s no market data to support it. The National Renewable Energy Laboratory and other research institutions provide general guidance, but appraisers are bound by what the local market demonstrates.

How to maximize your solar system’s appraised value

If you want your solar panels to contribute as much as possible to your home’s appraised value, start by organizing your documentation. Gather your original purchase agreement or loan documents, equipment specifications, warranty certificates, utility bill history showing production and savings, and any maintenance or service records. Present this to your real estate agent and appraiser as a complete package—it signals that the system is well cared for and worth including in the valuation.

Consider requesting an appraiser with green energy or solar valuation experience. Not all appraisers are trained in energy-efficient home features, and some may default to assigning minimal value simply because they’re unfamiliar with how to calculate it. Your agent can ask the lender to assign an appraiser who holds an Appraisal Institute green certification or who has documented experience with solar properties. Many appraisers now use the Residential Green and Energy Efficient Addendum, a standardized form that helps them systematically assess solar and other energy features.

If you’re in a strong solar market—California, Arizona, Texas, Colorado, or parts of the Northeast—make sure your agent pulls recent comparable sales of homes with solar. The more data the appraiser has showing that solar adds value in your neighborhood, the more confident they’ll be assigning a dollar figure. If comps are scarce, your agent may need to educate the appraiser on regional trends or provide research from sources like NREL or local utility programs that demonstrate solar’s value in your area.

Finally, if you’re selling a home with a leased system and want to maximize value, consider buying out the lease before you list. This converts the system from a liability into an asset, allowing the appraiser to include it in the home’s value. Not all leases allow early buyouts, and the cost may not always make financial sense, but it’s worth exploring.

Does solar appraisal value vary by state or region?

Yes. Solar appraisal value is heavily influenced by local electricity rates, solar adoption rates, and state-level incentives. In states with high electricity costs—like California, Massachusetts, Connecticut, and Hawaii—solar panels deliver more significant annual savings, which translates into higher contributory value. In states with lower electric rates or less sunlight, the financial benefit is smaller, and appraisers may assign less value accordingly.

Market familiarity also plays a role. In California, where solar is on tens of thousands of homes, appraisers have abundant comparable sales data and are comfortable assigning value to systems. In states where solar is less common, appraisers may struggle to find comps and default to conservative valuations. Some states have robust net metering policies that increase the value of solar by allowing homeowners to sell excess power back to the grid at retail rates, further boosting the system’s financial appeal and appraisal value.

State and utility incentives used to include significant upfront rebates and the federal Investment Tax Credit (ITC), which was eliminated at the end of 2025. Current incentives vary widely by state—some offer property tax exemptions for solar installations, meaning the added value won’t increase your annual property tax bill, while others provide sales tax exemptions or performance-based incentives. To see what’s available in your area, check DSIRE, the most comprehensive database of state and local solar incentives.

Bottom line: if you’re in a high-cost, high-adoption solar state, expect your appraiser to have an easier time justifying value. If you’re in a newer or lower-cost market, be prepared to provide more documentation and comps to support your case. For region-specific guidance, you can find a local solar installer who understands your market and can advise on typical appraisal outcomes in your area.

Common appraisal challenges and how to address them

One of the most common appraisal challenges is lack of comparable sales. If you’re in a neighborhood where few homes have solar, the appraiser has little market data to work with. In this case, your real estate agent should expand the search radius or provide comps from similar neighborhoods with solar. Some appraisers are open to reviewing data from nearby zip codes or using cost and income approaches as supplemental evidence.

Another challenge is outdated or poorly maintained systems. If your panels are 15 years old, show visible wear, or have a history of inverter failures, the appraiser will factor that into the valuation—or may assign no value at all if the system appears to be at the end of its useful life. If you know your system has issues, address them before listing. Replace a failing inverter, clean the panels, and document any recent repairs. For guidance on whether your system is outdated, see our article on outdated solar technology.

UCC liens and unclear ownership are another pitfall. If you financed your solar through a personal property loan (where the panels themselves are collateral), the lender may have filed a UCC-1 financing statement. This makes the panels personal property in the eyes of the law, and the appraiser cannot include them in the home’s value without the lien being released or subordinated. Before listing, check with your solar lender to confirm the financing structure and resolve any UCC filings if possible.

Finally, appraisers who lack solar training may undervalue or overlook the system entirely. This is especially common in rural or low-adoption areas. If your appraisal comes in lower than expected and you believe solar wasn’t properly valued, you can request a reconsideration of value. Provide additional comps, documentation, and research to support your case. Your real estate agent and mortgage lender can help you navigate this process.
