Does Solar Increase Home Value? Zillow & Redfin Market Data

One of the most common questions homeowners ask is: "Will I get my money back if I sell my house before the solar panels pay for themselves?" According to comprehensive real estate transaction data from Zillow and the Lawrence Berkeley National Laboratory (LBNL) study "Selling Into the Sun", the answer is generally yes.

Studies show that homes with solar panels sell for an average premium of 4.1% compared to similar homes without solar. For a $400,000 home, that represents a value increase of roughly $16,400. In many cases, this home value increase almost entirely offsets the net out-of-pocket cost of installing the system, allowing homeowners to recoup their investment immediately upon sale.

However, there is a massive catch that real estate agents and appraisers emphasize: **this premium only applies to owned solar systems.** If you purchased your solar panels with cash or a solar loan, they are considered an asset attached to the real property. The buyer inherits a system that generates free electricity, which justifies the higher home price.

In contrast, if your solar system is leased or under a Power Purchase Agreement (PPA), it is legally owned by the solar company. In this scenario, the solar panels are often viewed as a liability. To sell the home, the buyer must agree to take over the monthly lease payments and pass a credit check. If the buyer refuses, you may be forced to pay off the remaining balance of the 20-year lease (which can cost $15,000+) just to close the sale.

Furthermore, the value increase varies by geography. Solar panels add the most value in states with high electricity rates (like California, New York, and Massachusetts) and active solar markets. In these areas, homebuyers are already familiar with solar and actively seek out homes with lower monthly utility bills.
