# Do Solar Panels Increase Home Value? Costs, ROI & What Buyers Really Think in 2025 By Opendoor Editorial Team | 2026-03-11 If you're weighing a solar installation—or preparing to sell a home that already has one—you're probably asking a straightforward question: do solar panels increase home value enough to justify the investment? The short answer is yes, and the data is surprisingly strong. Research consistently shows solar-equipped homes sell for more and often sell faster than comparable homes without panels. But the real answer depends on your system, your market, and how long you plan to stay. This guide breaks down the actual numbers, the studies behind them, the variables that shift the math in your favor (or against it), and what today's buyers genuinely think when they see solar panels on a listing. [Get your offer](#) ## How Much Do Solar Panels Increase Home Value? The most widely cited figure comes from Zillow's market analysis: **solar panels increase home value by an average of 4.1% nationwide.** On a median U.S. home worth approximately $420,000 in 2025, that translates to roughly **$17,220 in added value**—just from having panels on the roof. The Lawrence Berkeley National Laboratory (LBNL) found an even more specific metric. Their landmark study analyzed over 23,000 home sales and determined that buyers pay a premium of approximately **$4 per watt of installed solar capacity.** For a standard 6 kW residential system, that's a premium of about $24,000. In practice, appraisals in high-electricity-cost markets have shown premiums of **$20,000 to $30,000 or more** for larger or newer systems. Homes in California, Massachusetts, New York, Connecticut, and Hawaii consistently land at the top of that range. But these are averages, and averages can mislead. The premium your home commands depends heavily on several [factors that influence home value](https://www.opendoor.com/articles/factors-that-influence-home-value): - **System size and age** — A newer 10 kW system adds far more than an aging 4 kW setup - **Ownership structure** — Owned systems add real value; leased systems often don't - **Local electricity rates** — The higher the rates, the more valuable solar savings become - **Geographic market** — Buyer demand for solar varies significantly by region - **Net metering policies** — Strong net metering makes solar more financially attractive to buyers The critical takeaway: solar panels are one of the few home improvements that can potentially return 70–100% or more of their cost at resale—before you even factor in years of energy savings. That puts solar in rare company among [home improvements that actually increase property value](https://www.opendoor.com/articles/home-improvements-that-actually-increase-property-value). ## What the Research Actually Says (Key Studies Breakdown) Vague claims about solar and home value are everywhere. Here's what the most rigorous research actually found. ### Lawrence Berkeley National Laboratory (LBNL) Study The LBNL study remains the gold standard. Researchers analyzed **23,000+ home sales across eight states** and found a consistent premium of roughly **$4 per watt** of installed solar capacity. A typical 6 kW residential system correlated with approximately $24,000 in added home value at the time of the study. Key findings worth noting: - The premium held across different housing markets and home types - **Newer systems commanded higher premiums** than older installations - The premium was present whether the home was in a hot solar market or a state with modest adoption rates ### Zillow's Market Analysis Zillow's analysis drew from millions of transactions in their database and found that the **4.1% average increase** varied significantly by market. Some Midwest markets saw premiums as low as **2.7%**, while metro areas like New York, San Francisco, and Orlando showed premiums of **5.4% or higher**. This geographic variation tracks closely with local electricity costs and buyer demographics—markets where energy bills are painful and environmental awareness is high consistently show the strongest solar premiums. ### National Renewable Energy Laboratory (NREL) Findings NREL's research added another dimension: **speed of sale.** Their findings showed that homes with solar sold **20% faster** and for **17% more** than comparable non-solar homes in certain markets. The speed factor matters because [days on market](https://www.opendoor.com/articles/why-days-on-market-matter) directly affect your negotiating position and final sale price. NREL also identified energy cost savings as the primary driver of buyer willingness to pay a premium—not environmental sentiment, but dollars and cents. ### Appraisal Institute Guidelines The Appraisal Institute recommends the **income approach** for valuing solar installations, typically using the **PV Value® tool**, which calculates the present value of a system's future energy production. This method is considered the most accurate way to capture what solar panels are actually worth to a buyer. The problem? **Many appraisers still lack specific training on solar valuation**, which frequently leads to undervaluation. This is one reason homeowners should proactively provide documentation during the [home appraisal process](https://www.opendoor.com/articles/home-appraisal-process)—a point we'll return to later. ## Factors That Determine How Much Value Solar Adds to Your Home Not all solar installations are valued equally. Here's what moves the needle. ### Owned vs. Leased Solar Panels This is the single biggest variable. **Owned systems add significantly more value** because the buyer inherits a fully paid asset that reduces their electricity costs from day one with no ongoing obligation. **Leased systems are a different story.** When you lease solar panels or enter a power purchase agreement (PPA), the buyer must agree to assume the lease—and many won't. Some buyers view a solar lease as a liability rather than an asset. Real estate agents consistently report that lease transfer requirements can slow deals, reduce offers, or cause transactions to fall through entirely. If you're considering solar with resale in mind, purchasing the system outright (or financing it with a loan you'll pay off) is the strongest play for home value. ### System Age, Size, and Condition Buyers are essentially purchasing the **remaining useful life** of your solar system. The math is intuitive: - A **3-year-old system with a 25-year warranty** has 22 years of production ahead—that's a significant asset - A **15-year-old system** nearing the end of its warranty has far less value to offer - **Larger systems** that offset a greater percentage of the home's electricity bill command higher premiums System condition matters too. Panels that have been properly maintained, with clean production records and no damage, appraise better. Keep your maintenance records—they're part of the documentation that supports your home's value, similar to the [items that increase home appraisal value](https://www.opendoor.com/articles/home-appraisal-tips-and-what-is-home-appraisal-based-on) in any category. ### Local Electricity Rates and Solar Incentives The value equation is straightforward: **the more expensive electricity is, the more valuable solar becomes.** A system that saves $250/month in Hawaii or California is worth substantially more than one saving $80/month in a low-rate state. States with **strong net metering policies**—where utilities credit you at or near retail rate for excess electricity you feed back to the grid—make solar systems more valuable to buyers. States that have weakened or eliminated net metering see correspondingly lower premiums. Active local and state incentive programs also amplify perceived value, as buyers recognize the financial advantages of an already-installed system. ### Geographic Market and Buyer Demographics Solar premiums are strongest in markets where three factors converge: **high electricity costs, eco-conscious buyer pools, and high solar adoption rates.** Sun Belt suburbs, coastal California, and Northeast metro areas consistently outperform. In markets where solar is common, buyers are educated about its value and less likely to discount it or view it with skepticism. In areas where solar installations are rare, some buyers may have concerns about aesthetics, maintenance, or roof integrity—factors that can temper the premium. Understanding your [local real estate market fundamentals](https://www.opendoor.com/articles/understanding-fundamentals-of-real-estate-market) is essential for estimating how much solar will add to your specific home. ## Solar Panel ROI: Do You Actually Make Your Money Back? Let's look at the full financial picture. The average residential solar installation in 2025 costs **$20,000 to $35,000 before incentives.** After the **30% federal Investment Tax Credit (ITC)**, that drops to roughly **$14,000 to $24,500** out of pocket. Your return comes from two streams: 1. **Annual energy savings:** $1,200–$2,000/year on average, depending on system size and local rates 2. **Home value premium:** $15,000–$30,000 at time of sale, based on the research above Between these two streams, most homeowners reach **breakeven within 6 to 10 years.** If you sell before breakeven, the home value premium can close the gap—though it's not guaranteed to cover the full remaining balance. Here's how solar compares to other popular [home improvements designed to increase value](https://www.opendoor.com/articles/improvements-that-increase-home-value): | **Renovation** | **Average Cost** | **Average ROI** | |---|---|---| | Solar panel installation | $14,000–$24,500 (after ITC) | 70–100%+ | | Minor kitchen remodel | $15,000–$35,000 | 75–85% | | Bathroom remodel | $12,000–$30,000 | 66–78% | | New roof | $8,000–$15,000 | 60–68% | | Garage door replacement | $2,000–$5,000 | 100%+ | According to [Bob Vila's analysis of high-ROI renovations](https://www.bobvila.com/articles/home-improvement-value/), kitchen and bathroom updates remain popular choices, but solar stands out because the ROI calculation includes both the resale premium *and* years of cumulative energy savings—something no other renovation offers. For a deeper comparison of which renovations deliver the best returns, see our guide on [best home improvements to increase value](https://www.opendoor.com/articles/best-home-improvements-to-increase-value-where-to-spend-for-maximum-roi-in-2025). ## What Home Buyers Actually Think About Solar Panels Research and ROI tables are one thing. What matters at the closing table is whether buyers will actually pay more for your solar-equipped home. The data says they will—mostly. A 2024 Zillow survey found that **67% of homebuyers** rate energy-efficient features as "very important" or "extremely important" in their home search. The National Association of Realtors (NAR) ranks solar panels among the **top features buyers are willing to pay a premium for**, alongside updated kitchens and modern HVAC systems. There's a clear **generational divide.** Millennial and Gen Z buyers—who now represent the largest share of the homebuying market—are significantly more likely to pay a premium for solar than Baby Boomers. For younger buyers, solar isn't just about savings; it's aligned with their values around sustainability and long-term financial planning. That said, not every buyer is enthusiastic. Common concerns include: - **Roof condition underneath the panels** — Buyers worry about hidden damage or the cost of re-roofing with panels installed. Getting a [home inspection](https://www.opendoor.com/articles/home-inspection-checklist-for-buyers) that specifically addresses the roof is a smart move before listing. - **Aesthetic preferences** — Some buyers prefer a traditional roofline, particularly on historic homes or in HOA-regulated communities - **Lease transfer obligations** — As noted above, this is a genuine deal-killer for some buyers - **Perceived maintenance costs** — Though solar panels require minimal maintenance, buyers unfamiliar with the technology sometimes overestimate the upkeep The takeaway for sellers: solar is a net positive with most buyer pools, but how you present it matters. Highlighting annual savings, warranty coverage, and system performance data in your listing can turn a passive asset into a genuine selling point. Understanding [how to sell your house for the most money](https://www.opendoor.com/articles/how-to-sell-your-house-for-the-most-money) means knowing how to market every advantage your home offers. ## How Solar Panels Are Valued in Home Appraisals Here's where theory meets reality—and where many solar homeowners run into frustration. There is **no single standardized method** for appraising solar panel value, which means the premium often goes underreported. This is one of the most common ways homeowners lose money at the appraisal stage. Appraisers generally use one of three approaches: - **Cost approach:** What was spent on the system minus depreciation. This is the simplest method but often undervalues the system because it doesn't account for future energy savings. - **Income approach:** Calculates the present value of the system's future energy production. The **PV Value® tool**, endorsed by the Appraisal Institute, is the gold standard here. This method typically produces the highest and most accurate valuation. - **Comparable sales approach:** Compares your home to similar solar-equipped homes that recently sold. This works well in markets with high solar adoption but falls short where comps are scarce. **Practical steps to protect your value at appraisal time:** Provide your appraiser with a complete documentation package: installation receipts, system specifications, warranty terms, energy production data, and utility bills from before and after installation. The more data you provide, the harder it is for the appraiser to undervalue your system. For more on what appraisers look for, see our guide on [items that increase your home appraisal value](https://www.opendoor.com/articles/items-that-increase-your-home-appraisal-value-what-appraisers-actually-look-for). It's also worth noting that automated valuation models—the algorithms behind tools like Zillow's Zestimate or Redfin's Estimate—[may not fully capture solar panel value](https://listwithclever.com/real-estate-blog/home-value-estimate-websites/). These tools rely on public data and comparable sales, and they struggle with unique features like solar installations. Their accuracy limitations (median errors of 6–7%+ for off-market homes) mean they should be a starting point, not the final word on [how much your house is worth](https://www.opendoor.com/articles/how-much-is-my-house-worth-7-ways-to-find-out-your-homes-value). ## Does Solar Make Sense If You're Planning to Sell Soon? Your timeline changes the calculus significantly. **Selling within 1–2 years:** You likely won't recoup the full installation cost from the home value premium alone. However, when you combine the premium with the 30% federal tax credit and 1–2 years of energy savings, the math can still work—especially in high-electricity-cost markets. If you're already planning to [sell your house](https://www.opendoor.com/articles/how-to-sell-your-house), focus your listing marketing on the system's remaining warranty, annual savings, and transferable benefits. **Selling within 3–5 years:** Much stronger case. You'll capture most of the federal ITC benefit, accumulate meaningful energy savings, and the system will still be new enough to command a strong resale premium. This is the window where the combined financial return often exceeds the initial investment. **Staying 7+ years:** Almost always worth it financially. You'll likely hit breakeven on energy savings alone within this period, and the home value premium at sale becomes pure upside. This is the scenario where solar delivers its best returns. **Key practical consideration:** Solar installations typically take 1–3 months from contract to activation, including permitting and utility interconnection. Factor this into your selling timeline, especially if you're trying to maximize [how long closing takes](https://www.opendoor.com/articles/how-long-does-closing-take) and coordinate your sale. ## How to Accurately Estimate Your Home's Value with Solar Knowing your home's value—with solar factored in—requires more than a single data point. **Start with online estimators for a baseline.** Tools from Redfin, Zillow, and Realtor.com can give you a general range, but recognize their limitations. These automated valuation models rely on algorithms, public records, and comparable sales data. They're useful for establishing a ballpark but [may not fully reflect the value of unique features](https://listwithclever.com/real-estate-blog/home-value-estimate-websites/) like solar panels. For off-market homes, median error rates can range from roughly 6.5% to 7.5%—which on a $420,000 home could mean being off by $27,000 to $31,000. **For a more accurate figure, request a Comparative Market Analysis (CMA)** from a local real estate agent. A CMA is the gold standard for setting a list price because it incorporates local expertise, recent comparable sales, and knowledge of what features (including solar) are valued in your specific market. Most agents provide CMAs for free. Our guide on [how to accurately estimate your home's value](https://www.opendoor.com/articles/how-to-accurately-estimate-your-homes-value) walks through this process in detail. **If considering a cash offer or iBuyer route,** understand that these offers are typically below market value—companies need to account for their fees, repairs, and profit margins. These platforms may not fully credit solar panel value, so compare any offer against your CMA and online estimates before deciding. **Best practice:** Get 2–3 estimates from different sources and cross-reference them. Always provide your appraiser or agent with full solar documentation—installation receipts, production data, warranty information, and utility savings records. The more evidence you provide, the more accurately your home's value will reflect the solar investment. For additional methods, see our comprehensive guide on [how much your house is worth and seven ways to find out](https://www.opendoor.com/articles/how-much-is-my-house-worth-7-ways-to-find-out-your-homes-value). ## Top Questions People Ask About Solar Panels and Home Value ### Do solar panels add value if they're leased? Leased solar panels add **little to no resale value** and can actively complicate a sale. When panels are leased, the buyer must agree to assume the remaining lease payments—and many won't. Some transactions fall through entirely because of lease transfer friction. If the buyer views the lease terms as unfavorable (which happens frequently), it can become a negotiation obstacle rather than a selling point. If you currently have a leased system and plan to sell, consider buying out the lease before listing if the numbers make sense. A fully owned system is a clear asset; a leased system is, at best, neutral. ### Can solar panels actually hurt your home's value? It's uncommon, but possible. The most likely scenarios include: - **Outdated or poorly installed systems** that raise concerns about roof integrity or electrical safety - **Homes in markets with very low electricity costs**, where the savings don't justify the visual impact - **Historic homes or HOA-governed neighborhoods** where aesthetic uniformity is highly valued - **Systems that require a roof replacement** underneath—the cost of removing, re-roofing, and reinstalling panels can be a deterrent In the vast majority of cases, properly installed and owned solar systems are a net positive. But condition and context matter. Getting a [roof assessment](https://www.opendoor.com/articles/does-a-new-roof-increase-home-value-roi-appraisal-impact-what-sellers-need-to-know) before listing is wise if your panels are over a decade old. ### How much does solar increase home value per kW? Based on LBNL data, the premium is approximately **$3,000 to $4,000 per kilowatt** of installed capacity. A typical residential system ranges from 6 to 10 kW, which translates to a premium of roughly **$18,000 to $40,000** depending on the system size and market. Newer systems at the higher end of that per-kW range, older systems at the lower end. Markets with high electricity costs tend to push premiums toward the top of the range. ### How do I know how much my house is worth right now? There are several reliable methods, and combining them gives you the clearest picture. Online estimators from major platforms provide a starting point, but they have [known accuracy limitations for off-market properties](https://listwithclever.com/real-estate-blog/home-value-estimate-websites/). A free CMA from a local real estate agent offers more precision, especially for homes with features like solar that algorithms may miss. For the most definitive number, a professional appraisal—using the income approach for solar valuation—provides a figure that lenders and buyers will rely on. Our guide to home value estimator tools covers this in depth. ### Will renovating my house increase its value more than solar? It depends entirely on what you renovate. Solar panels typically deliver **70–100%+ ROI** when you factor in both the resale premium and cumulative energy savings. By comparison, a [minor kitchen remodel averages 75–85% ROI](https://www.bobvila.com/articles/home-improvement-value/), and a bathroom renovation returns 66–78%. A garage door replacement is one of the few renovations that consistently matches or exceeds solar's returns. The unique advantage of solar is the **ongoing savings** component. A kitchen remodel looks great but doesn't reduce your monthly expenses. Solar does both—it adds resale value and puts money back in your pocket every month. ### Is it worth renovating before selling, or should I invest in solar instead? The answer depends on your home's current condition and your timeline. If your kitchen is severely dated or your bathrooms need functional upgrades, those [improvements should likely come first](https://www.opendoor.com/articles/should-you-make-home-improvements-before-listing)—buyers expect baseline functionality. But if your home is already in good condition and you're choosing between discretionary upgrades, solar offers one of the strongest combined returns available. For a full breakdown of which improvements deliver the best value, see our guide on [what adds the most value to a home](https://www.opendoor.com/articles/what-adds-value-to-a-home-fences-decks-windows-landscaping-more-2025-roi-guide). ### How do cash offer companies factor in solar panel value? Cash offer companies and iBuyers use their own valuation models to generate offers. Because their business model requires accounting for fees, repairs, and profit margins, their offers are typically below what you'd get in a traditional sale. Solar panel value may not be fully credited in these offers because their algorithms prioritize speed and standardization over nuanced valuation of individual features. If you're considering a cash offer, it's smart to also get a CMA from a local agent so you can compare and understand [what you might expect to make](https://www.opendoor.com/articles/how-much-can-you-expect-to-make-when-you-sell-your-home) through different selling paths. ### Is buying a solar-equipped home worth paying a premium for? For buyers, the math is usually favorable. You're inheriting a system that immediately reduces your electricity costs, with no installation hassle or wait time. The premium you pay is typically less than what it would cost to install a new system yourself—and you start saving from your first month of ownership. The key is due diligence: verify the system is **owned (not leased)**, review the warranty terms, request energy production data, and confirm the roof is in good condition underneath. A home with a well-maintained, fully owned solar system is generally worth the investment. [Get your offer](#) ## Frequently Asked Questions ### Do solar panels increase home value? Yes. Research consistently shows solar panels increase home value by an average of 4.1% nationally, with premiums ranging from $15,000 to $30,000+ depending on system size, age, location, and ownership structure. ### How much do solar panels add to a home appraisal? Approximately $3,000–$4,000 per kilowatt of installed capacity, based on LBNL research. A typical 6–8 kW system can add $18,000–$32,000 to an appraised value when properly documented. ### Do leased solar panels increase home value? Leased panels add little to no value and can complicate sales, since buyers must assume the lease. Some deals fall through over lease transfer issues. ### Can solar panels decrease home value? Rarely, but it's possible with aging systems, poor installations, aesthetic concerns in historic or HOA communities, or in markets with very low electricity costs. ### How long does it take for solar panels to pay for themselves? Most homeowners break even in 6–10 years through combined energy savings and the federal tax credit. If you sell before breakeven, the home value premium can close the gap. ### What is the federal solar tax credit in 2025? The Investment Tax Credit (ITC) covers 30% of solar installation costs. On a $25,000 system, that's a $7,500 tax credit. ### Do solar panels make a house harder to sell? No—research from NREL shows solar homes sell 20% faster in many markets. The exception is leased systems, which can slow the selling process. ### How much does a solar panel system cost in 2025? Average residential installations cost $20,000–$35,000 before incentives, or $14,000–$24,500 after the 30% federal ITC. ### Are solar panels worth it if I'm selling my house soon? If selling within 1–2 years, the math is tight. Within 3–5 years, significantly better. Staying 7+ years makes solar almost always worth it financially. ### How accurate are online home value estimators for solar homes? Online tools may not fully capture solar panel value. Their median error rates for off-market homes range from roughly 6.5% to 7.5%. A CMA from a local agent is more reliable for homes with solar. ### Should I provide documentation about my solar system to the appraiser? Absolutely. Provide installation receipts, system specs, warranty information, production data, and before-and-after utility bills. This helps the appraiser use the income approach for the most accurate valuation. ### How does solar compare to other renovations for ROI? Solar delivers 70–100%+ ROI when combining resale premium and energy savings—outperforming most kitchen remodels (75–85% ROI), bathroom renovations (66–78%), and roof replacements (60–68%). ### Do solar panels affect property taxes? Many states offer property tax exemptions for solar installations, meaning the added home value won't increase your tax bill. Check your state's specific policies, as this varies. ### What's the best way to determine my home's overall value? Combine multiple estimates: start with online tools for a baseline, request a free CMA from a local agent for precision, and consider a professional appraisal for a definitive figure.
