Do Solar Panels Increase Home Value? (2026 Data)

Yes — owned solar panels generally increase a home’s value, by roughly 4% on average according to multiple studies, and solar homes tend to sell faster than comparable homes without them. The research on this is fairly consistent across different markets and time periods. But there are important qualifiers: the premium depends on ownership, location, system condition, and how you present it to buyers and appraisers.

Here’s what the data actually shows and how 2026’s changed financial environment affects the calculation.

What the Research Shows

Two major studies are frequently cited on solar home value:

Zillow (2019): Homes with solar panels sold for an average of 4.1% more than comparable homes without solar. On a $400,000 home, that’s roughly $16,400. The study controlled for other factors like size, location, and renovation level — the premium was specifically attributable to solar.

Lawrence Berkeley National Laboratory (multiple studies, 2015–2022): Berkeley Lab found buyers paid roughly $15,000–$20,000 more for a home with a typical residential solar system. This closely tracks the system’s net cost, suggesting the market effectively values solar at close to what it costs to install. Updated studies found the premium persisting even as solar costs have declined — possibly because buyers value the ongoing savings rather than the replacement cost.

Speed of sale: Solar homes tend to sell faster as well. The Zillow study found solar homes sold about 20% faster on average than comparable non-solar homes. Buyers who are interested in solar are actively searching for it, creating a ready pool of motivated buyers.

Why Solar Adds Value

The underlying mechanism is straightforward: buyers value lower operating costs. A home that produces most of its own electricity is a home with predictable, lower monthly expenses. Given that utility rates have risen roughly 3% per year nationally over the past decade — and some years much faster — a fixed-cost energy source is genuinely attractive.

1. Reduced utility bills. A buyer who moves into a solar home and sees a $30/month electric bill (versus $200/month in a comparable non-solar home) is experiencing a direct financial benefit. That’s worth real money when aggregated over a 25-year ownership horizon.

2. Hedge against rising electricity costs. Solar locks in a large portion of your energy cost at whatever it cost to install. As utility rates increase — and they consistently do — the value of that locked-in production increases alongside them. Buyers understand and price this in.

3. Home modernity and energy efficiency signaling. Solar installations often co-occur with other efficiency upgrades (insulation, smart thermostats, LED lighting). But even on its own, solar signals a modern, thoughtfully maintained home — similar to how a renovated kitchen reads as “move-in ready.”

4. Climate and resilience value. In some markets — particularly in areas with frequent outages, wildfire risk, or strong sustainability culture — solar has added value beyond the financial. This is especially true when paired with battery storage.

The Big Catch: Owned vs. Leased

This distinction matters enormously, and it’s the most important factor beyond location.

Owned panels (paid cash or loan fully paid off): Add full value. They transfer to the buyer free and clear. The buyer gets all the benefits — reduced electricity cost, potential net metering income, no contract obligations.

Active solar loan (system owned but financing attached): The buyer typically assumes the loan or you pay it off at closing. Most buyers can handle this, but it adds a step. The home still qualifies for the solar premium; you may just need to negotiate how the loan is handled in the transaction.

Leased panels or PPA: This is where it gets complicated. The solar company owns the system, and any new buyer must qualify for and assume the lease contract — often a 20–25 year agreement with annual payment escalators. Many buyers are unwilling to take on a multi-decade lease obligation they didn’t choose. Studies show leased solar can reduce home value or make the home harder to sell. Lease buyout costs at time of sale are often $10,000–$30,000 depending on remaining term.

If you’re considering solar and care about resale value: own the system, not lease it. The ownership premium vs. leasing disadvantage can be a $20,000–$40,000 swing in how the home is received at sale.

How the 2026 Environment Affects the Home Value Question

One shift worth noting: the elimination of the 30% federal residential tax credit in 2026 means buyers cannot retroactively benefit from that credit on a used system. A buyer isn’t getting a new installation — they’re inheriting an existing one. The value they care about is the ongoing electricity savings, not what it cost to install.

This means the home value premium from solar depends more than ever on:

• Your local electricity rate — high-rate states (CA, MA, HI, CT) produce larger annual savings and command larger premiums
• How much useful life remains — a 2-year-old system at peak production is worth more than a 20-year-old system nearing end of warranty
• Panel output and condition — a system that’s underperforming or missing monitoring data will be harder to value

The research showing ~4% premium was conducted primarily in markets before the federal credit was eliminated. We don’t yet have post-2026 data, but the fundamental economic logic holds: buyers pay for future savings, and the future savings from a solar home haven’t changed just because the credit expired.

What Affects How Much Value You Actually Get

Location and electricity rate: The premium is larger in high-rate states because the savings are larger. A $200/year savings story is less compelling to buyers than a $2,500/year savings story. Check what solar homeowners in your specific market are seeing — a local real estate agent with solar transaction experience can give you ground-level data.

System age and remaining life: A 3-year-old system with 22 years of warranty remaining is worth meaningfully more than a 20-year-old system with 5 years left. The panel degradation curve (about 0.5% per year) means an older system produces less — buyers can and should factor this in.

Ownership status: As discussed above, owned > loan > paid-off-at-sale > lease.

Equipment quality and warranty transferability: Tier-1 panels with manufacturer warranties that transfer to new owners are more valuable than no-name panels with limited support. Ask your installer about warranty transferability before you buy.

Documentation: Appraisers and buyers can’t value what they can’t verify. If you have good records, the system is easy to value.

How Solar Is Appraised

Traditional home appraisers sometimes undervalue solar because they use the “cost approach” — comparing installed cost to depreciated replacement value. This often underestimates what buyers actually pay.

The Uniform Standards of Professional Appraisal Practice (USPAP) includes guidance on solar appraisal, and tools like the PV Value tool (developed with support from the National Renewable Energy Laboratory) let appraisers calculate value based on the income stream — what the solar production is actually worth over time at current utility rates. This approach better captures market reality.

What you can do to get a fair appraisal:

1. Request that the appraiser use the income approach for the solar component, or use the PV Value tool.
2. Provide a complete documentation package: install contract, equipment specs with model numbers, production data from the past 12 months, warranty certificates, and any net metering agreements.
3. Find comparable sales of solar homes in your area — “solar comps.” Your real estate agent can pull these.
4. If you’re refinancing (not just selling), ask your lender explicitly whether they’ll commission a solar-aware appraisal.

Selling a Solar Home: Practical Tips

Lead with the numbers, not the technology. Buyers respond to “this home’s electricity bills average $28/month” more than to “the home has a 9 kW solar array.” Translate the system into what the buyer experiences.

Get your monitoring data ready. Most modern systems have an app (Tesla Powerwall, Enphase Enlighten, SolarEdge) that shows production data. Print or export monthly production for the past year. This makes the savings story concrete and verifiable.

Disclose clearly and early. In most states you’re required to disclose the solar system’s ownership status, loan or lease obligations, and any HOA issues. Do this proactively — buyers who are surprised by a lease in the middle of escrow tend to back out or renegotiate.

Know your lease buyout cost if applicable. If you have a lease, find out the current buyout price. Some sellers decide to buy out the lease before listing to remove the complication entirely.

Work with an agent who has sold solar homes. They’ll know how to find solar comps, how to present the system’s value in marketing, and how to navigate the appraisal conversation.

Do You Need Battery Storage to Maximize Home Value?

Battery storage (like a Tesla Powerwall) adds value, but more modestly than panels and primarily in markets with frequent outages or high electricity rates. The home value premium for batteries hasn’t been as clearly documented as the premium for panels — but buyers in wildfire-prone California, hurricane-prone Florida, and storm-affected Northeast markets increasingly value resilience features.

If you’re adding storage for resilience reasons, it likely adds some value. If you’re adding it purely for home value, the math is less clear. Focus on panels first.

Bottom Line

Owned solar adds roughly 4% to home value on average — about $15,000–$20,000 on a typical system — and solar homes tend to sell faster. The keys: own the system (not lease it), keep good documentation, and know how to present the production data to buyers and appraisers.

In 2026, with longer payback periods due to the eliminated federal credit, the ownership advantage versus leasing is even sharper than before. Solar homes that are cleanly owned and well-documented continue to command premiums. Solar homes with lease complications continue to face headwinds at sale.

For the financial picture before you buy: run the solar savings calculator for your state, read how much solar costs in 2026, and review the financing options to understand the ownership vs. lease trade-off before committing to either.
