As Arizona temperatures climb into the triple digits, many homeowners begin paying closer attention to their energy bills—and naturally, solar becomes part of the conversation. Whether a system was installed years ago or recently added, one of the most common questions appraisers receive is:
"How much value do my solar panels add to my home?"
The answer is often more nuanced than many homeowners expect.
Not All Solar Systems Are Valued the Same
One of the biggest misconceptions about solar is that every system automatically increases a property's market value. In reality, the type of solar ownership plays a significant role in how both the market and an appraiser evaluate the system.
Leased Solar Systems
In Arizona, leased solar systems are generally considered personal property rather than real property. Because the homeowner does not own the equipment outright, the system typically does not contribute measurable value to the real estate itself.
While a leased system may help reduce monthly utility expenses, that benefit is often viewed as a use benefit rather than a marketable ownership benefit. Buyers are frequently required to assume the lease agreement, which can influence how they perceive the property during a transaction.
For appraisal purposes, leased systems generally do not warrant a direct line-item adjustment solely for the presence of solar.
Owned Solar Systems
Owned systems are evaluated differently because the homeowner owns the equipment as part of the real property.
However, determining contributory value involves much more than knowing the original installation cost. Appraisers analyze system specifications and market evidence to understand how buyers react to solar-equipped homes compared to similar non-solar properties.
Key system characteristics may include:
System size and production capacity
Module and inverter warranties
Estimated degradation rates over time
Array configuration and roof placement
Tilt and orientation toward the sun
Inverter specifications and efficiency
Overall age and condition of the system
Like a roof, HVAC system, or pool, solar panels experience depreciation over time and do not necessarily return dollar-for-dollar what was originally invested.
What Arizona Buyers Are Looking At
Arizona's climate creates a unique environment where energy efficiency often carries greater buyer interest than in many other parts of the country.
Throughout the Phoenix metropolitan area, buyers are typically purchasing the benefit of lower operating costs rather than purchasing solar panels themselves. The market ultimately determines how much value those benefits contribute to a property.
Why Solar Value Is Not One-Size-Fits-All
Two homes may have solar systems with dramatically different impacts on market value depending on factors such as:
Ownership structure
System age and production capability
Local utility rates and energy costs
Property price range and market segment
Buyer preferences within a specific neighborhood
A newer, fully owned system with strong production and transferable warranties may receive a very different market reaction than an older system approaching the end of its useful life.
This is why appraisers rely on market-supported analysis rather than broad assumptions or installation costs alone.
Understanding Solar in the Arizona Market
As energy costs remain a topic of discussion across Arizona, solar will likely continue to be a feature many homeowners and buyers evaluate when comparing properties.
Understanding the distinction between leased and owned systems—and recognizing that value is driven by market reaction rather than installation cost—can help set realistic expectations during a sale, refinance, estate settlement, divorce proceeding, or litigation assignment.
At OnPoint Appraisals, every assignment is analyzed within the context of the local market, buyer behavior, and property-specific characteristics. Whether evaluating a suburban residence, luxury home, acreage property, or energy-efficient residence, the goal remains the same: providing credible valuation analysis supported by market evidence.
