Yes, solar panels increase home value when you own them outright. National research puts the average premium between 4.1% (Zillow, 2024) and 6.9% (SolarReviews, 2025), adding roughly $15,000 to a median-priced home according to the U.S. Department of Energy. In high-demand markets like California, the premium climbs to 5 to 10%, translating to $39,500 to $79,000 on a $790,000 home.
Six variables determine where your home lands in that range:
- Ownership: Owned systems add 3 to 10%. Leased systems and power purchase agreements add $0 and can complicate the sale.
- System size: Zillow research values each kilowatt of solar capacity at $5,911 in added home value.
- Solar panel age: Systems older than five years may raise buyer concerns about replacement cost and remaining lifespan.
- Local electricity rates: Higher rates mean larger annual savings, which translate into a larger solar home premium.
- Net metering policy: Homes with grandfathered NEM 1.0 or NEM 2.0 agreements in California carry a financial advantage no new installation can replicate.
- Appraisal methodology: Most appraisers rely on the comparable-sales method, which routinely undervalues solar in markets with few solar-equipped comps.
This guide covers how much value solar adds by study and state, the owned vs. leased split, what drives the premium up or down, how to navigate the solar panel appraisal process, how solar compares to other home improvements on ROI, and whether adding solar before a sale makes financial sense in 2026.

How much do solar panels increase home value?
The solar panel home value increase percentage varies by source and market, but three well-cited data sets bracket the range consistently.
National average: 4.1% or 6.9%?
Both figures are accurate for their samples. U.S. Department of Energy solar home value research found homes with solar sold for roughly $15,000 more than comparable homes without. Zillow’s 2024 analysis puts the national premium at 4.1%, or about $16,400 on a $400,000 home. SolarReviews’ 2025 study found a higher figure of 6.9%, translating to roughly $29,000 on a $420,000 home.
The gap between studies reflects different time periods, geographic mixes, and home price points. A Qcells analysis cited in the Google AI Overview uses a $450,000 home as a reference: at 3 to 4%, that’s a $13,500 to $18,000 increase. Neither figure applies to leased systems.
Solar panels home value research from multiple institutions agrees on one point: the premium is real, measurable, and nationally consistent for owned systems.
Value per kilowatt installed
Zillow’s per-kilowatt solar premium analysis provides a more granular calculation: each kilowatt of solar capacity adds roughly $5,911 in home value. A 5 kW system adds about $29,555. A 7 kW system adds approximately $41,400. A 10 kW system adds roughly $59,110.
The kilowatt solar value approach works well in markets where solar comps are sparse, because it does not require finding a recently sold solar-equipped home nearby to produce a defensible number.
High-solar markets like California
California represents the clearest case of an above-average premium. An EnergySage analysis of more than 5,000 California home sales found the premium ranges from 5 to 10%, adding $39,500 to $79,000 on a $790,000 home. The Lawrence Berkeley National Lab solar premium data provides the primary-source research underpinning many of those California figures, and remains the foundational citation for solar premium studies nationally.

Owned vs. leased solar: how it affects home value
The owned vs. leased split is the most consequential variable in solar panels home value calculations. Every major AI engine foregrounds this binary because the financial outcome is binary: ownership creates a premium, a lease creates a complication.
Owned solar panels: the value-add breakdown
Owned solar panels add 3 to 10% to home value and transfer automatically to the buyer at title closing. No third-party approval, no monthly payment to assume. Per the NAR 2024 Sustainability Report on solar buyer preferences, 31% of real estate agents say buyers consider solar an important feature. As the Google AI Overview notes, buyers are “highly motivated by the long-term energy savings that come with zero power bills.” That motivation is what drives them to pay more.
The solar panels home value premium for owned systems is consistent across every major study. Ownership status is the single prerequisite.
Leased panels and power purchase agreements
Leased solar panels and power purchase agreements (PPAs) add $0 in measurable home value. Instead of a premium, they introduce a buyer qualification step: the buyer must apply with the leasing company, pass a credit check, and agree to assume the remaining contract with its monthly payment and annual escalator clause.
A typical solar lease runs 20 to 25 years. A system installed ten years ago leaves the buyer with a 10 to 15 year remaining obligation. Leased solar panels home value impact is neutral at best. In markets where buyers are unfamiliar with lease assumptions, the seller’s pool narrows quickly.
Sellers have one clean exit before listing: buy out the lease. Buyout costs typically run $5,000 to $15,000 depending on remaining term and the contract’s purchase-option clause. That upfront cost clears the complication entirely.
How to transfer a solar lease to a buyer
If a buyout is not feasible, a solar system transfer follows a defined sequence. Contact the leasing company as soon as you list, well before you have a buyer. Request a transfer packet containing the buyer’s credit application and lease assignment documents. Budget 30 to 60 days for leasing company review and approval. Both parties sign the assignment agreement before closing. Confirm the transfer is recorded before the deed changes hands.
Missing any step delays closing. Experienced cash buyers who handle lease transfers regularly can move through this process faster than financed buyers facing simultaneous lender and leasing company timelines.
The leased solar panels home value dynamic is distinct from owned solar in every measurable way: no premium, added friction, and a defined resolution path that takes time.
| Owned Solar | Leased / PPA | |
|---|---|---|
| Value premium | 3 to 10% added value | $0 added value |
| Sale complexity | Simple, transfers with title | Buyer must qualify with lessor |
| Transfer process | Automatic at closing | 30 to 60 day approval process |
| Buyer qualification | No extra steps | Credit check required by lessor |
| Bottom line | Selling advantage | Potential deal complication |
What factors affect solar’s impact on home value
The solar panel home value increase percentage is not fixed at the national average. Four variables shift the premium meaningfully in either direction.
System size and output capacity
Size is the most direct variable. At $5,911 per kilowatt, a 5 kW system adds roughly $29,555 while a 10 kW system adds roughly $59,110 to the same home. Buyers pay for the savings a solar energy system produces, so higher output justifies a higher purchase price. Sellers who document actual annual kWh production, rather than rated capacity alone, make that case more credibly.
Age of the solar panels
Solar panel age is one of three factors the Google AI Overview names explicitly. Systems older than five years can prompt buyer concerns about remaining lifespan and replacement cost. That concern does not necessarily eliminate the premium. Panels typically last 25 to 30 years with a degradation rate of about 0.5% per year. Inverters are the time-sensitive component, usually needing replacement at 10 to 15 years at a cost of $1,500 to $3,500.
Providing buyers with current monitoring data showing actual production output resolves most age-related objections before they become negotiating leverage.
Local electricity rates and demand
Higher local electricity rates translate directly into larger annual savings, which drive a larger solar home premium at resale. Hawaii’s average residential rate of roughly $0.35/kWh supports a strong solar home premium even on modest systems. Louisiana’s rate of roughly $0.10/kWh narrows the annual savings and therefore the premium. When comparing markets, electricity rate is often a more predictive variable than system size.
Net metering laws and grandfathered rates
Net metering determines how much a utility pays for excess solar production exported to the grid. The state net metering policy database at DSIRE tracks current rules across all 50 states.
California’s NEM 3.0, effective April 2023, cut solar export compensation rates by approximately 75% for new installations. Homes with systems grandfathered under NEM 1.0 or NEM 2.0 earn dramatically more for excess production. That rate cannot be replicated by any new installation today, making a grandfathered net metering agreement a transferable financial asset. Sellers in California now name their grandfathered NEM status explicitly in listing descriptions. Other states, including Florida, Arizona, and Nevada, have modified their net metering programs in recent years, reducing the future solar home premium in those markets for new buyers. Verify the current policy in your state before listing.
Do solar panels add value in every state?
Readers searching “do solar panels increase home value in California” will find stronger data than anywhere else in the country. Solar panels home value impact is greatest where electricity rates are high, net metering policies are favorable, and solar adoption is established. In low-rate, low-adoption markets, the premium can be minimal or unmeasurable.
California: the highest solar premium
Do solar panels increase home value in California more than elsewhere? Yes, by a significant margin. The state’s combination of high electricity rates (averaging around $0.30/kWh), strong buyer demand for solar homes, and the transferable NEM 1.0/NEM 2.0 advantage drives a 5 to 10% premium. On a $790,000 home, that’s $39,500 to $79,000. Sellers with grandfathered net metering increasingly name it in listing descriptions, because a new buyer cannot replicate that rate with a fresh installation under NEM 3.0.
High-value solar states beyond California
Several other states consistently produce above-average premiums:
- Hawaii: The highest residential electricity rates in the U.S. (roughly $0.35/kWh) make annual solar savings large in dollar terms, supporting a strong premium regardless of system size.
- New Jersey and Massachusetts: Strong state net metering policies and above-average electricity rates push premiums above the national average.
- Arizona, Nevada, and Florida: Significant solar adoption and moderate electricity rates produce premiums in the 3 to 5% range.
- Colorado and Texas: Large solar markets with variable outcomes; lower rates in parts of Texas limit the savings calculation and the resulting premium.
Where solar may not add measurable value
In Midwest and Plains states with low electricity rates (Iowa, North Dakota, Wyoming), the annual savings from a solar energy system are smaller in dollar terms. NAR data shows 34% of agents nationally say buyers perceive solar as a value increase, but that perception is not uniform. In low-adoption markets, some buyers treat the system as a maintenance obligation rather than a value driver. The solar panel home value increase percentage in those states can approach zero, making installation before a near-term sale difficult to justify financially.
Is it harder to sell a home with solar panels?
No. For owned systems, solar panels make a home easier to sell, not harder.
Owned solar: a documented selling advantage
Homes with owned solar panels sell 13 to 20% faster than comparable homes without solar. They are 24.7% more likely to sell above asking price, per research from fbfs.com. A realtor.com analysis of more than 400 listings found approximately a 6.8% price premium for solar homes. The NAR 2024 Sustainability Report confirms the underlying demand: 31% of real estate agents say buyers consider solar an important feature when evaluating homes.
The driver is practical. Buyers who purchase a home with owned solar panels inherit lower monthly operating costs from day one. That future savings value is reflected in what they are willing to pay today.
Leased solar: when complications arise
Leased panels reverse the picture. The buyer must qualify with the leasing company, pass a credit check, and commit to the remaining contract with its payment and escalator clause. Some buyers are disqualified by the leasing company’s credit standards, which narrows the buyer pool. Others decline when they understand the monthly obligation they are assuming.
The 30 to 60 day lease-transfer timeline adds friction to a process most buyers expect to complete in 30 to 45 days total. That friction becomes a negotiating point at or before closing.
How quickly do solar homes sell?
Speed data from multiple independent sources points consistently in the same direction for owned systems. DOE research found solar homes sold faster and for more than comparable non-solar homes. The 24.7% above-asking rate from fbfs.com reinforces that finding. Leased-panel homes show the reverse pattern: the qualification and approval process adds time rather than reducing it.
The practical conclusion: ownership status determines whether solar is a speed advantage or a speed penalty in your transaction.
How appraisers value solar panels
Solar panels are frequently undervalued at appraisal because most residential appraisers use the comparable-sales method, and in most U.S. markets outside California, Arizona, and New Jersey, there are too few solar-equipped comps to produce a reliable result.
Why solar appraisals often fall short
The comparable-sales method requires recent sales of similar homes with similar solar systems in the same market. Where those comps are scarce, a solar energy system gets assigned a token value or none at all. The Google AI Overview names this gap directly: “the added equity relies heavily on what an individual buyer is willing to pay out-of-pocket.”
When a lender’s appraiser assigns too little value in the solar panel appraisal, the appraised value falls below the contract price. That triggers a renegotiation or a deal collapse. Understanding the appraisal methodology, and knowing how to direct an appraiser toward a better one, closes that gap before it becomes a problem.
Sellers preparing their solar documentation package are often handling multiple pre-listing costs at the same time. Pre-listing inspection costs covers what else to budget for at this stage.
The PV Value methodology explained
The PV Value tool, available at NREL’s PV Value tool for income-approach solar appraisals, provides an income-approach alternative to the comparable-sales method. It calculates the present value of a solar system’s future energy savings using local utility rates and the system’s actual production history. The output is a defensible appraised value that does not depend on finding a comparable solar-equipped sale nearby.
The income approach is recognized by the Appraisal Institute as a valid methodology for solar valuation. Not all appraisers use it by default. You may need to request it explicitly when the appraisal is ordered.
What to give your appraiser before listing
title: How to Document Your Solar System for Maximum Appraisal Value
steps: – title: Pull the last 12 months of utility bills. detail: Export or print your electricity statements and calculate the annual kWh reduction since solar installation. This is the primary evidence an appraiser needs to quantify your system’s energy savings in dollars.
-
title: Export production data from your solar monitoring app. detail: SolarEdge, Enphase Enlighten, and Tesla apps all provide CSV exports of lifetime kWh produced. Download a one-year summary and print it. Production history is more credible than the system’s rated capacity alone.
-
title: Locate all ownership and warranty documents. detail: Gather the original purchase contract, installation permit, panel equipment warranty (typically 25 years), and inverter warranty (typically 10 to 12 years). If the system is leased, locate the full lease agreement and contact the leasing company for a transfer packet before listing.
-
title: Ask your appraiser to use NREL PV Value methodology. detail: When selecting or briefing your appraiser, ask explicitly whether they are familiar with the PV Value income-approach tool. This methodology calculates the present value of future energy savings, a more defensible figure than comp-based methods in markets where solar comps are scarce.
-
title: Prepare a one-page Solar Savings Summary for the buyer. detail: Include system size in kW, annual production in kWh, average annual utility savings in dollars, remaining warranty years for panels and inverter, and your most recent monitoring screenshot. Buyers who can read the numbers immediately are more likely to pay full value without renegotiating.
-
title: Disclose all solar details in the seller’s disclosure statement. detail: State whether the system is owned or leased, the year of installation, system size, any known issues, and for leased systems the monthly payment, remaining contract term, and escalator clause. Incomplete disclosure is the most common cause of solar-related deal collapses after contract.
Solar vs. other home improvements: ROI compared
When comparing home improvement ROI across project types, solar stands apart in one critical way: it is the only upgrade that also eliminates a recurring monthly cost. A kitchen remodel increases home value but does not reduce your utility bill. Solar does both.
Solar ROI vs. a kitchen or bathroom remodel
The federal Residential Clean Energy Credit (30% through 2032) changes solar’s cost equation fundamentally. A $20,000 system costs $14,000 after the 30% credit. If that system adds $15,000 in home value and saves $1,200 to $2,500 per year in electricity, the total return over 10 years outpaces most single renovation projects by a wide margin.
For context on how solar stacks up against other common upgrades, see fireplace value and ROI.
Compare solar to other improvements, per Remodeling Magazine’s Cost vs. Value 2024 data:
| Improvement | Avg Cost | Est. Added Value | Notes |
|---|---|---|---|
| Solar (owned, after ITC) | $10,500 to $17,500 | $15,000 median + energy savings | Only upgrade that reduces monthly costs |
| Minor kitchen remodel | ~$28,500 | ~$32,100 | Approx. 113% recoup |
| Midrange bathroom remodel | ~$25,000 | ~$17,500 | Approx. 70% recoup |
| Garage door replacement | ~$4,500 | ~$8,700 | Approx. 194% recoup nationally |
| Steel entry door | ~$2,400 | ~$4,500 | Approx. 188% recoup |
Based on Remodeling Magazine Cost vs. Value 2024 and DOE/NREL solar premium research. Verify current figures before transacting.
Why solar’s ROI compounds over time
A kitchen remodel delivers a one-time value event. Solar panel ROI compounds annually. Each year, the home avoids $1,200 to $2,500 in utility costs. The 30% federal ITC reduces the upfront cost in year one. The home value premium is locked in from the date of installation. In high-electricity markets, the 10-year net present value of a solar energy system routinely exceeds any single renovation project in dollar terms.
When to choose solar over other upgrades
Solar makes the most sense when you plan to stay in the home long enough to capture energy savings (at least two to three years), when your local electricity rate is above the national average, and when your state has a favorable net metering policy. If you’re choosing between solar and a traditional renovation purely for resale, calculate your local electricity rate and your state’s current net metering rules first. The home improvement ROI comparison shifts significantly based on those two inputs.
Is solar worth it before selling your home?
Adding solar before a sale makes financial sense in some markets and rarely makes sense in others. The break-even depends on three inputs: local electricity rates, your state’s net metering policy, and how long you’ll own the home before listing.
When adding solar before a sale makes sense
California, Hawaii, and New Jersey are the clearest cases. In those states, the solar panel ROI stacks three layers: a home value premium that meets or exceeds the after-credit install cost, annual energy savings during the period you still own the home, and the residential clean energy credit reducing your upfront outlay by 30%. In high-electricity states, all three layers produce meaningful returns, and the math can work even for sellers planning to list within 12 to 18 months.
When solar before a sale may not pay off
In Midwest and Plains states with low electricity rates, the home value gain rarely covers the install cost for a seller listing within 6 to 12 months. Annual savings are too small to fill the gap, and the solar home premium in low-adoption markets is uncertain. A practical rule applies: if you’re selling within 12 months in a low-rate state, the numbers typically do not work. If you’re staying two or more years, the energy savings, federal credit, and value premium stack more favorably.
To compare listing platforms as you plan your selling timeline, real estate listing sites covers the main options currently available.
The federal solar tax credit in 2026
The residential clean energy credit lets you deduct 30% of your solar installation cost from federal taxes through 2032, per the IRS. On a $20,000 system, that is a $6,000 reduction in your federal tax bill in the year the system is placed in service. The credit steps down to 26% in 2033 and 22% in 2034, then expires. There is no dollar cap on the credit amount.
The federal solar tax credit applies to system owners only. Buyers who assume a leased system receive no tax benefit.

Frequently Asked Questions
Yes, owned solar panels increase home value by an average of 4.1% nationally, adding roughly $15,000 to a median-priced home. The premium applies only to systems the homeowner owns outright, not leased systems or power purchase agreements. In California, the premium reaches 5 to 10%, adding $39,500 to $79,000 on a $790,000 home.
Nationally, owned solar panels add roughly $5,911 per kilowatt installed, or about 4.1% of home value, per Zillow research. SolarReviews’ 2025 study found a higher average of 6.9%. A 7 kW system at the $5,911 kilowatt solar value rate adds approximately $41,400 in estimated home value.
Leased solar panels add no measurable value to a home and can complicate the sale because buyers must qualify to assume the remaining lease. A typical solar lease runs 20 to 25 years. Paying off or buying out the lease before closing costs $5,000 to $15,000 but eliminates the buyer qualification requirement entirely.
No. Homes with owned solar panels sell 13 to 20% faster and are 24.7% more likely to sell above asking price, per published research. Difficulty arises only with leased systems, where buyer qualification and lease-transfer paperwork can add 30 to 60 days to the transaction.
The 20% rule recommends sizing your solar system to produce 20% more electricity than your average monthly usage as a buffer for production losses. If your home uses 1,000 kWh per month, size the system to produce 1,200 kWh. The buffer accounts for shading, inverter efficiency losses of 15 to 20%, and seasonal demand variation.
Most appraisers use the comparable-sales method, but limited solar comps in most markets cause solar systems to be routinely undervalued in the solar panel appraisal process. NREL’s PV Value tool offers an income-approach alternative, calculating present value of future energy savings using local utility rates and the system’s actual production history.
Yes, solar panels increase home values in California by 5 to 10%, adding $39,500 to $79,000 on a $790,000 home, well above the national 4.1% average. The premium reflects high electricity rates, strong buyer demand, and the value of grandfathered NEM 1.0 and NEM 2.0 agreements that no new installation under NEM 3.0 can replicate.
Owned solar panels transfer to the buyer automatically at title closing with no additional paperwork. Leased panels require the buyer to assume the remaining contract through a 30 to 60 day leasing company approval process. Some sellers pay off the lease before listing to remove the qualification hurdle from the solar system transfer.
Systems older than five years can raise buyer concerns about replacement cost and remaining lifespan, potentially reducing the premium or triggering a renegotiation. Panels typically last 25 to 30 years with about 0.5% annual degradation. Providing current monitoring data showing actual production output mitigates most age-related objections before negotiations start.
Yes, homes in states with favorable net metering, especially those with grandfathered NEM 1.0 or NEM 2.0 agreements in California, carry measurably higher solar premiums. California’s NEM 3.0, effective April 2023, cut export compensation by roughly 75% for new installations. Grandfathered agreements earn more for excess production and represent a transferable financial asset a new buyer cannot otherwise obtain.
Homes with owned solar panels sell 13 to 20% faster than comparable homes without solar, per multiple real estate data providers. They are also 24.7% more likely to sell above asking price. Leased-panel homes show the opposite pattern, with the qualification and approval process adding 30 to 60 days to close.
The residential clean energy credit lets you deduct 30% of your solar installation cost from federal taxes through 2032, per the IRS. On a $20,000 system, the 30% credit equals a $6,000 reduction in your federal tax bill for the year the system is placed in service. The credit steps down to 26% in 2033 and 22% in 2034.
Adding solar makes financial sense only if you plan to own the home at least two more years before selling. In median markets, the roughly $15,000 home value premium approximately matches the after-credit install cost of $10,500 to $17,500, making the near-term economics roughly neutral. In California, Hawaii, or New Jersey, the premium typically exceeds cost; in low-electricity-rate states, the solar panel ROI rarely justifies installation before a near-term sale.
Sellers are generally required to disclose the solar system’s ownership status, age, any lease terms, and known defects in the seller’s disclosure statement. In most states, a leased solar system is treated as a fixture or encumbrance that must be disclosed. Providing documentation proactively, including warranty records, monitoring data, and utility bills, reduces the chance of an inspection-triggered renegotiation after contract.
