Quick answer: Yes, owned solar increases a California home’s value, typically by 5 to 10%, or roughly $40,000 to $80,000 on an $800,000 home. But the premium is not automatic. It goes almost entirely to owned systems, not leases; it is larger in California than nationally because of high electricity rates; and in 2026 it is shaped by two things most articles ignore: the net metering grandfathering you hand the buyer, and California’s solar property tax exclusion, which expires January 1, 2027.
Key takeaways
- California owned-solar homes sell for about 5 to 10% more than comparable non-solar homes, higher than the national 4 to 7% because California’s electricity is so expensive.
- Only owned systems earn the premium. Leased and PPA systems show no measurable resale bump and can shrink your buyer pool.
- A pre-April-2023 NEM 2.0 system is a transferable asset: the buyer inherits your grandfathered retail-rate export credits, worth 4 to 8 times more than NEM 3.0.
- California does not reassess property tax on the value solar adds, but that exclusion sunsets January 1, 2027.
- With the federal credit gone for buyers in 2026, an existing owned system is more attractive to buyers, not less, because they cannot easily replicate it with incentives.
“Do solar panels increase property value” is the question I get from every homeowner who is thinking about selling in the next few years. The honest answer is yes, but the number depends on things a national blog post cannot tell you: whether you own the system, which net metering tariff it carries, and how your appraiser handles it. In California in 2026 those three levers matter more than the panels themselves. Here is how the value actually shows up at the closing table.
How much do solar panels increase home value in California?
Owned solar adds roughly 5 to 10% to a California home’s sale price, which outpaces the national range. The most California-specific evidence is a SolarInsure analysis of about 5,000 California home sales from 2020 to 2023, which found homes with owned solar sold for 5 to 10% more than comparable homes without. Nationally the effect is real but smaller: a 2025 SolarReviews study replicating Zillow’s methodology found a 6.9% average premium, about $29,000 on a median US home, up from Zillow’s older and endlessly-quoted 4.1% figure.
Why bigger in California? Because the premium tracks the electricity bill it erases. When power runs 35 to 46 cents per kWh, a paid-off system that wipes out most of that bill is worth real money to the next buyer. The same panels in a low-rate state save less, so they add less.
Table: What a California solar premium looks like in dollars, 2026
| Home sale price | 5% premium | 6.9% premium | 10% premium |
|---|---|---|---|
| $700,000 | $35,000 | $48,300 | $70,000 |
| $800,000 | $40,000 | $55,200 | $80,000 |
| $1,000,000 | $50,000 | $69,000 | $100,000 |
| $1,200,000 | $60,000 | $82,800 | $120,000 |
Ranges from SolarInsure (California, ~5,000 sales) and SolarReviews 2025 (Zillow-method replication). Actual premium varies by system size, ownership, and local rates.

Takeaway sentence for below the chart: every credible study points the same direction, and California sits at the top of the range because its electricity rates make a bill-killing system worth more to buyers.
Does owned vs. leased solar change the home value?
This is the single biggest lever, and it decides whether you get a premium at all. Owned systems, bought with cash or a loan you have paid off, transfer to the buyer as a clean asset with no strings, and appraisers can assign them value. Leased and PPA systems are a different story. The same California research that found a 5 to 10% premium for owned solar found no measurable premium for third-party-owned systems.
Worse, a lease can actively complicate the sale. The buyer has to qualify for and assume your contract, or you have to buy it out before closing. Plenty of buyers simply do not want a 15-year obligation attached to the house, which shrinks your buyer pool and can stall a deal. If resale value is part of why you are going solar, ownership is what preserves it. We lay out the ownership tradeoffs in our solar loans vs. leasing guide.
The asset nobody mentions: the net metering grandfathering you pass to the buyer
Here is the 2026 detail that almost no property-value article covers, and it can be worth thousands. In California, net metering grandfathering is attached to the home’s interconnection agreement, not to you as a customer. When you sell, the buyer inherits the remaining years of it.
If your system received Permission to Operate (PTO) before April 15, 2023, it is on NEM 2.0, grandfathered for 20 years from that PTO date, and per the CPUC that protection transfers with the property. This matters because NEM 2.0 credits exported power at close to the full retail rate, roughly 4 to 8 times what a new NEM 3.0 system earns. A buyer purchasing your home in 2026 cannot get NEM 2.0 anymore by installing their own system. They can only get it by buying a home that already has it. That makes a grandfathered system a genuine, and increasingly scarce, selling point.
Put a number on it. A home that exports around 3,000 kWh a year is earning perhaps $800 to $960 more per year in export credits under NEM 2.0 than the same exports would earn under NEM 3.0. With a decade or more of grandfathering left, that is well over $10,000 of inherited benefit the buyer would lose if they walked away and built new. Two cautions worth telling sellers: expanding the system by more than about 10% can reset it to NEM 3.0, and a NEM 3.0 home still conveys its system, it just does not carry the same premium export terms. For the mechanics, see our NEM 2.0 vs. NEM 3.0 explainer.
How do solar panels affect property tax in California?
In California, installing solar does not raise your property tax, because the state excludes the added value from reassessment, but that exclusion is expiring. The active solar energy system exclusion means that when solar raises your home’s value, the county assessor does not reassess it and does not bump your tax bill. This is unusual and valuable, and it is the direct answer the older version of this page got wrong by assuming solar always raises property tax.
The catch for 2026: the exclusion is currently set to sunset January 1, 2027. A system completed and placed in service before that date locks in the exclusion under current rules; systems added later may be treated differently unless the legislature extends it. If you are weighing an install partly for resale value, finishing in 2026 protects both the home-value premium and the property tax treatment. Verify current status, because this is exactly the kind of deadline that can move.
How does an appraiser value solar on my home?
An appraiser typically values owned solar using the income approach or the cost approach, and giving them the right documentation is what turns your system into appraised value rather than an ignored roof ornament. The income approach capitalizes the energy savings: a widely-cited Berkeley Lab and NREL framework values roughly $20 of home value for every $1 of annual bill savings, so a system saving $4,000 a year can support around $80,000 in value. The cost approach uses installed cost minus depreciation. Real-world premiums usually land between the two.
The practical lesson from our sellers: hand your agent and appraiser a simple packet, the paid invoice, system size and equipment, warranty documents, the PTO letter showing the net metering tariff, and 12 months of production and savings data. Appraisers cannot credit what they cannot see. An owned, documented, NEM 2.0 system with a transferable warranty appraises far better than an identical system with no paperwork.
Does the expired federal tax credit change resale value?
No, and if anything it slightly strengthens the case for an existing owned system. The federal residential tax credit (Section 25D) expired December 31, 2025, so a buyer who wanted to install their own solar in 2026 gets no federal credit and pays full price. That makes an already-installed, owned system on the home they are considering more attractive by comparison, because it delivers the savings without the buyer having to fund a system at post-credit prices. The resale premium is driven by the bill the system erases, not by the incentive you did or did not receive when you installed it. For current pricing context, see our California solar cost guide.
FAQ
Do solar panels increase home value in California?
Yes. Owned systems add about 5 to 10% to a California home’s sale price, higher than the national 4 to 7%, because the state’s high electricity rates make the bill savings more valuable to buyers. Leased systems show no measurable premium.
How much value does solar add to an $800,000 California home?
Roughly $40,000 to $80,000 at a 5 to 10% premium. The exact figure depends on system size, whether you own it, your local utility rate, and the net metering tariff it carries.
Do leased solar panels add home value?
Generally no. Research on California sales found no measurable premium for third-party-owned systems, and a lease the buyer must assume can shrink your buyer pool. Buying out the lease before selling restores the owned-system premium.
Will solar panels raise my property taxes in California?
No, not currently. California excludes the value solar adds from property tax reassessment. That exclusion is set to expire January 1, 2027, so completing a system in 2026 locks in the current treatment.
Does net metering transfer when I sell my solar home?
Yes. NEM grandfathering is tied to the property’s interconnection agreement, so the buyer inherits the remaining years. A pre-April-2023 NEM 2.0 system passes on retail-rate export credits worth several times more than a new NEM 3.0 system, which makes it a real selling point.
Do solar homes sell faster?
Research has generally found solar homes sell somewhat faster than comparable non-solar homes, though the size of that effect varies by market and study. In high-rate California markets, buyer demand for lower bills supports both a faster sale and a higher price.
