Owned solar panels generally add value to a home, and the research supports a premium of roughly $3 to $4 per watt, or $15,000 to $25,000 on a typical system, in markets where buyers understand solar. Leased and PPA systems are a different story: they can complicate the sale, shrink your buyer pool, and occasionally knock value down. The honest answer depends almost entirely on who owns the equipment, how old it is, and how well your local market knows solar.
What the Evidence Actually Says
The most cited research comes from Lawrence Berkeley National Laboratory, which analyzed roughly 23,000 home sales across eight states in its 2015 “Selling Into the Sun” study. Owned systems carried a premium near $4 per watt. Zillow’s 2019 analysis reached a similar direction, finding solar homes sold for about 4.1% more on average.
Both numbers get abused in sales pitches, so here’s the framing the pitches leave out. The LBNL data is from 2015, when solar was rarer and premiums may have reflected scarcity. Four percent of a median price means wildly different dollars in San Diego versus Des Moines. And a per-watt premium only produces a big number when the system is big, new, and owned outright. If a salesperson quotes you “$15,000 in added value” before asking a single question about your roof or your utility, treat it as marketing.
The defensible summary: owned panels usually recover a meaningful share of their installed cost at sale time, especially when electricity is expensive and the system is recent. They rarely recover all of it, because buyers discount for equipment age and transfer risk.
Why Estimates Vary So Much
Six variables explain almost all the spread between “solar adds nothing” and “solar adds $30,000.”
| Factor | Effect on resale value |
|---|---|
| Owned outright | Positive, typically $3-$4 per watt in solar-friendly markets |
| Leased or PPA | Neutral to negative; adds a contract buyers must assume |
| System age | Premium fades as panels, inverters, and warranties age |
| Local power rates | High rates amplify the savings story buyers can verify |
| Roof under the panels | New roof helps; a tired roof cancels the premium |
| Clean paperwork | Documented production and warranties speed the sale |
Ownership structure is the biggest. Owned systems add value. Leased systems add a contract the buyer must accept, which is a liability dressed up as an amenity.
System age matters because panels degrade about 0.5% per year and warranties transfer on a schedule. A 2-year-old system with 23 warranty years left reads very differently from a 14-year-old system a few years from an inverter replacement. Appraisers and buyers both price that.
Local electricity rates drive the savings story. Offset power at 35 cents per kWh in California is worth triple the same production at 12 cents in Texas.
Appraiser knowledge is a real bottleneck. Many appraisers have few solar comps and no green-design training, so they default to minimal or zero value. FHA guidelines allow appraisers to count owned panels but explicitly exclude leased ones from appraised value, which tells you how the industry defaults.
Condition of the roof under the panels shapes buyer psychology. Panels on a 5-year-old roof read as a package. Panels on a roof due for replacement read as a $4,000 removal-and-reinstall bill.
Perceived hassle shows up in days-on-market. Solar homes in solar-savvy markets sell fine. In markets where agents field confused questions about the lease every showing, some buyers just move to the next listing.
The Leased System Problem
If you lease your panels or signed a PPA, you don’t own them, so there’s nothing to add to your appraisal. What you have is a monthly payment with years left on it, often 15 to 20, and possibly a 2 to 3% escalator.
Selling means one of two things. The buyer assumes the lease, which requires qualifying with the lease company and accepting the payment schedule. Or you buy out the contract, which can run $10,000 to $20,000 depending on age, effectively paying off equipment a buyer may not have wanted. Either path adds friction at the exact moment a deal is most fragile. Buyer agents know this, and some buyers filter out leased-solar listings entirely.
Financed systems deserve a caution flag too. A solar loan secured by a UCC-1 filing, which most are, shows up in a title search like a lien. It must be paid off at closing, which is fine mechanically, but surprise liens discovered late in escrow have killed deals. If your loan has a UCC-1, disclose it early and have the payoff amount ready.
What Buyers Actually Ask
Prepare answers to these before you list, because they come up in nearly every showing of a solar home:
- Who owns the system, and is there any loan or lease attached to it?
- What did it actually produce last year? Twelve months of utility bills beat any projection.
- What warranties remain, and do they transfer to a new owner for free?
- How old is the roof under the panels?
- Is there a UCC-1 filing, and what’s the payoff amount?
- Who services it if something breaks?
A folder with the installation contract, production history, utility bills, warranty documents, and inverter model answers 90% of this in one move. We’ve heard repeatedly from agents that solar homes with clean paperwork sell like any other house, and solar homes with missing paperwork invite lowball offers, because the buyer prices the unknown.
Mistakes to Avoid
Don’t buy a system primarily to raise your resale value. Panels are a long-term energy play first, and our solar panel installation cost guide shows the payback math works over 11 to 15 years of ownership, not over a quick flip. If you might move within three to five years, solar is usually the wrong purchase right now.
Don’t lease because the monthly payment looks smaller. Run the full sale-scenario math before signing, including what assumption or buyout does to a future sale. And don’t let anyone talk you into a system sized for the neighbor’s roof; oversizing a home that exports most of its power makes a poor value story for both you and the next owner.
When you’re collecting bids for a new system, watch for installers who lead with resale-value promises. Inflated appreciation claims sit squarely among the contractor quote red flags we warn about. If your roof is the weak link in the value story, sort that first, and our roof repair vs replace guide walks through that call.
Bottom Line
Owned solar panels generally help your home’s value, with defensible premiums around $3 to $4 per watt in solar-friendly markets, but the number depends on system age, local rates, and appraiser knowledge, so distrust anyone quoting one figure at you. Leased and PPA systems usually work against you at sale time. The best thing you can do for resale starts the day of installation: own the system, keep every document, and make sure the roof under the panels is in long-service condition.
FAQ
Do solar panels increase property taxes?
Often yes, because a higher assessed value can mean higher taxes. Many states offer property tax exemptions for solar, so the added value goes untaxed, but the rules vary by state. Check your state’s treatment before assuming the premium is pure gain.
Do buyers really pay more for a house with solar?
In high-electricity-rate markets, usually yes, with owned systems showing premiums of roughly $3 to $4 per watt in the best-known research. In low-rate or solar-unfamiliar markets, buyers often pay little or nothing extra. The system must be owned, working, and documented for the premium to appear.
Is it harder to sell a house with leased solar panels?
Frequently, yes. The buyer must qualify to assume the lease or you must buy it out, and either step adds friction that some buyers refuse to accept. Agents in lease-heavy markets report filtered-out listings and slower sales for leased-solar homes.
Do solar panels need to be removed when selling a house?
No. Panels stay with the house. The only removal scenario is a buyout provision in some leases, or a buyer specifically demanding removal as a negotiation point, which is rare but does happen with contentious leases.
