Owned solar panels may add meaningful value to your home—multiple studies point to an average premium of roughly 4–7% for homes with owned systems—but that figure comes with important caveats. The value lift varies widely by location, local electricity rates, system age, and, critically, whether you own or lease your panels. Treat solar as a strong potential upgrade, not a guaranteed windfall, and do the math for your specific home and market before committing.
How Much Do Solar Panels Typically Add to Home Value?
The honest answer is: it depends, but the research trend is encouraging for homeowners who own their systems outright. A 2025 SolarReviews study found that homes with solar panels sold for about 6.9% more on average than homes without solar. That's a meaningful premium—but it's an average drawn from a wide range of markets, system sizes, and conditions.
Other data points tell a similar, if slightly more conservative, story. A Zillow study found that homes with solar installations tend to sell for about 4.1% more than homes without. Some locations show a higher value add—5.4% for New York City—while others show lower, around 2.7% for Riverside, California. Meanwhile, a SolarInsure study of over 5,000 homes found that homes with owned solar panels tend to sell for 5–10% more than comparable homes without solar, reflecting buyer demand for long-term energy savings and stability.
Why do buyers pay more? According to the 2024 REALTORS & Sustainability report by the National Association of REALTORS Research Group, 44% of homebuyers found utility costs to be an important factor during the buying process, and 57% of real estate agents found promoting energy-efficient features somewhat valuable. Simply put, lower monthly electricity bills are a real selling point that informed buyers are willing to price in.
How Much Does a Solar System Cost—and Is That the Right Starting Point?
Before you can evaluate payback, you need a realistic cost baseline. For many homes, the total price of a solar installation falls somewhere between about $16,000 and $31,000 before incentives, with the average 12 kW system near $30,500. Larger homes, premium equipment, batteries, and complex roofs can push the number higher.
- System size: Larger systems generate more power but cost more upfront. Systems average about $2.60 per watt before incentives, though the number varies significantly by installer and region.
- Incentives: The federal Residential Clean Energy Credit (the 30% tax credit) expired for most homeowner-purchased systems after 2025. That does not automatically mean solar is a bad investment—it means your economics now depend more heavily on utility electricity rates, your self-consumption, local rebates, property tax exemptions, and whether you buy with cash, use a loan, or choose third-party ownership. Always verify current incentives with a qualified solar installer or your state's energy office before budgeting.
- Payback period: Solar panels typically have an average payback period of about 10 years, after which you can expect roughly 15 years of effectively free solar energy. Your market and usage will move that number up or down.
- State variation: Costs depend heavily on your state—ranging from around $13,958 in Arizona to $21,082 in Hawaii for installation alone.
The upshot: do not evaluate solar purely on the home-value premium. The full investment picture includes energy savings over the system's lifespan, local incentives, financing costs, and—yes—the likely effect on your sale price. All of those variables belong in one place.
Does It Matter Whether You Own or Lease Your Solar Panels?
Yes—ownership structure is arguably the single most important factor in whether solar adds resale value. Third-party-owned systems (leases and PPAs) do not consistently increase home value or resale value, as buyers may be wary of taking over contracts. An owned solar system—whether you paid cash or financed with a loan—is treated as part of the property you're selling, meaning its full value can be reflected in your sale price. In contrast, with a solar lease or Power Purchase Agreement (PPA), the panels are owned by a solar company; this arrangement can complicate a sale because potential buyers might hesitate to take over a lease contract, and since the homeowner doesn't technically own the system, leased panels typically don't boost the home's appraised value the same way an owned system would.
Leasing isn't automatically bad—lower monthly energy bills during your time in the home can be genuinely useful—but if resale value is a goal, ownership is what the data supports. Some newer prepaid lease and PPA products offer a path to ownership before you sell your home; if you buy out or complete payments on your agreement and own the system outright by the time you list, you may see the same property value increases as systems purchased from day one.
What Factors Affect How Much Value Solar Panels Add?
The 4–7% average is exactly that—an average. Several variables pull that number in either direction for any individual home:
- Location and local electricity rates: Residential utility bills averaged $144 per month in the U.S. in 2024. In states like Connecticut or Hawaii, where monthly costs exceeded $200, the increased savings from solar panels are more appealing to buyers—and command a larger premium. The highest premiums tend to be in states with expensive electricity and strong incentives: California, New Jersey, Massachusetts, New York, Florida, and Hawaii lead the way.
- System age and condition: The age of the solar equipment slightly affects the premium, with newer systems often adding more value; overall, the long-term savings from owned solar is what drives higher sale prices.
- System size: A system that meaningfully offsets a home's electricity use is more attractive than an undersized one that covers only a fraction of the bill.
- Market saturation: If comparable homes in your area don't have solar, yours stands out. If they do have solar, not having it could put your home at a disadvantage. In areas where solar is popular, buyers have come to expect the feature and may pay a premium for a house that already has panels installed.
- Documentation and maintenance records: A buyer's willingness to pay more for solar is tied to confidence that the system works. A clean service history, warranty paperwork, and performance reports remove doubt and support a stronger appraisal.
What About Property Taxes on the Added Value?
Higher home value typically means a higher assessed value—and potentially a higher property tax bill. That's a real consideration, but many states have put protections in place. As of 2025, 29 states offer property tax exemptions for residential solar installations, meaning that if you live in one of those states, the added value from your solar panels will not increase your property tax bill.
Based on the median home value in the U.S., homeowners in states without such an exemption can expect solar panels to increase their annual property taxes by between $160 and $630. That range is modest relative to the potential sale-price premium, but it's worth factoring into your payback estimate. Because tax impacts vary by situation, consult a licensed CPA or tax professional for guidance specific to your home—Cribfolio helps you track the records; your tax pro handles the tax strategy.
How Does Solar Compare to Other Home Upgrades on ROI?
Evaluated purely on resale return, solar often compares favorably to other common renovations—though the comparison is most favorable when you include energy savings, not just sale-price premiums. Solar outperforms many traditional home improvements with superior ROI, providing potential for 100%+ cost recovery plus ongoing energy savings over 25 years, compared to kitchen remodels (typically around 75% recovery) and bathroom additions (around 63% recovery) that offer no additional utility savings.
That said, no upgrade is a slam dunk in every market. The smart approach is to run the numbers for your home: What does installation actually cost in your ZIP code today? What does your utility currently charge per kWh, and what's your average monthly bill? How long do you plan to stay in the home? Payback math changes significantly if you sell in 5 years versus 15. The Cribfolio upgrade payback tool lets you model those estimated scenarios against your home's current value—so you're making a decision based on your numbers, not national averages.
How Do I Keep Track of My Solar System for Resale?
Good records are money in the bank when it's time to sell. Appraisers and buyers will want to verify what they're buying, and a well-documented system commands more confidence—and potentially a higher price—than an undocumented one. Here's what to keep organized:
- Installation contract and equipment specs — panel brand, wattage per panel, total system size (kW), inverter type and model.
- Warranty documents — most quality panels carry a 25-year performance warranty; the inverter warranty is typically 10–12 years. Keep both.
- Permits and inspection records — a permitted system is an appraiser-friendly system.
- Annual production reports — month-by-month kWh output history demonstrates the system performs as claimed.
- Maintenance and service records — any cleaning, inverter replacements, or repairs.
- Financing documents — if you have a solar loan, document that it's attached to you, not the property. If it's a PACE/property-assessed loan, a future buyer's lender needs to know.
Cribfolio is built exactly for this: you can store warranty docs, appliance records, receipts, and upgrade details in one place, and the app's Home Value estimate and Cribfolio Home Grade reflect your home's overall condition—including improvements like solar—so you always know roughly where you stand before you list.
Is Solar Worth It If You Own a Rental or Investment Property?
For landlords and investment property owners, the solar calculus is slightly different. Lower utility costs may make a unit more attractive to tenants (especially in a lease structure where the tenant pays electricity), but the resale premium math is identical to primary residences: owned systems in high-electricity-rate markets tend to add the most value. If you manage multiple investment properties, tracking each system's documentation, warranty status, and production history separately—and connecting that data to each property's estimated value—is the kind of organized record-keeping that pays off at refinance time as well as at sale.
Speaking of refinancing: if a solar installation has meaningfully improved your home's estimated value, that change may affect your loan-to-value ratio and open up refinance options worth reviewing with your lender. Cribfolio surfaces those kinds of refinance and insurance considerations so you don't miss them.
The Bottom Line: What Should You Do Before Installing Solar?
Here's a practical pre-installation checklist based on everything the research tells us:
- Plan to own, not lease — if resale value matters to you, own the system outright or via a solar loan attached to you personally.
- Check your state's property tax exemption — 29 states currently offer one; knowing this changes your net-cost math.
- Get multiple installer quotes — per-watt pricing varies enough that competitive quotes are worth the time.
- Estimate your payback period honestly — factor in your local electricity rate, your annual consumption, and how long you plan to own the home.
- Document everything from day one — permits, warranties, production data, service visits. Future buyers and appraisers will reward you for it.
- Check current incentives independently — federal and state programs change; verify with your installer and your state energy office before assuming any credit is still available.
