8 Questions to Ask Before Buying a House With Solar Panels

Key takeaways

• Buying a house with solar panels can offer long-term savings and added property value when properly evaluated.
• Always confirm whether the solar panels are owned or leased before making an offer.
• Review system documentation, including installation date, warranty details, and utility savings.
• Understand how solar agreements may affect financing and insurance requirements.

With solar panels now on roughly 7% of homes in the U.S., it’s becoming more common for buyers to consider homes that already come equipped with this energy-saving upgrade.

These devices could be a great addition, whether you’re in the market for a home in Plano, TX, or have put an offer on a home in Los Angeles, CA.

While solar panels can be a huge perk, they also come with a few things you should look into before making an offer. This guide will walk you through questions to ask, key benefits, and potential challenges when buying a house with solar panels.

1. What are solar panels and how do they work? 

Solar panels are devices designed to capture sunlight and convert it into usable electricity for your home. They’re made up of photovoltaic (PV) cells that absorb energy from the sun and turn it into power your home can use.

Most solar systems are mounted on the roof, where they get the most sun exposure. The number of panels depends on the home’s energy needs, and some setups include a battery to store extra power for nighttime use or outages.

For homebuyers, solar panels can mean lower utility bills and a reduced carbon footprint. They’re a clean, renewable energy option that makes a home more efficient—and possibly more appealing down the line if you decide to sell.

2. Why should you consider buying a home with solar panels? 

Buying a house with solar panels already installed can be a great move, especially if you are looking to lower utility costs or reduce your environmental footprint. Solar panels offer clean energy and may increase the overall value of the home. They can also provide long-term savings by cutting down on monthly electricity bills. For many buyers, it feels like getting a head start on energy efficiency without having to invest in the installation yourself.

3. Will you own or lease the solar panels? 

One of the most important things to ask early in the buying process is whether the solar panels are owned outright or if they are leased. This detail can significantly impact your decision.

If the homeowner owns the panels, you will typically not have to worry about additional monthly payments or transferring a lease. The value of the panels is usually factored into the sale price.

If the panels are leased, you may be required to take over the lease agreement. This could affect your financing or debt-to-income ratio. Make sure to review the lease terms and find out if the provider allows for a smooth transfer of the agreement. You will also want to confirm how much longer the lease lasts and what maintenance responsibilities fall on you as the new owner.

4. What’s the condition of the panels and roof? 

Solar panels are built to last, often with warranties ranging from 20 to 25 years. Still, it is important to inspect the system’s current condition. During the home inspection, request that the inspector look closely at the roof and the solar equipment. You may also want to ask the seller for documentation that shows the installation date, manufacturer details, and maintenance history.

If the system includes a solar battery for energy storage, ask about its condition and remaining lifespan. Replacing a solar battery can be expensive, so it is helpful to know if this is something you will need to budget for.

5. How do solar panels affect your financing and insurance? 

Some lenders may view solar leases or power purchase agreements as a form of debt. That means the monthly payment associated with the solar agreement could be counted when calculating your loan eligibility. If the panels are owned, this typically will not be an issue.

You will also want to let your home insurance provider know about the solar system. In many cases, insurance can easily cover solar panels that are attached to the home, but it is best to verify this upfront so there are no surprises later.

6. Will you actually save on energy costs? 

Not all solar panel setups are created equal. A home’s energy savings will depend on panel size, system efficiency, local climate, and your own energy usage. Ask the seller for recent utility bills so you can compare them with similar homes in the area.

If the house includes a net metering agreement, you may be able to earn credits for excess energy that the system sends back into the power grid. This can lead to even more savings, but it is important to check with the local utility company to understand how it works in your area.

7. Can you upgrade or expand the system? 

Maybe you are planning to add an electric vehicle or just want more coverage. If you think you might want to upgrade the solar system in the future, make sure to ask whether the current setup allows for it. This may include checking if the inverter has capacity for additional panels or if the roof can support more solar equipment.

8. What are the pros and cons of buying a house with solar panels?

Buying a home with solar panels already installed can seem like an attractive perk. After all, solar energy promises environmental benefits and potential savings on your energy bills. However, before getting too excited, it’s smart to weigh the advantages against the potential drawbacks.

FAQs: 

Who installed the solar system, and when?

Ask for the name of the installer and the installation date. Knowing who installed the system can help you verify its quality, and the timeline gives you an idea of how much life is left in the equipment.

Do solar panels transfer to the new owner?

Is there a warranty in place, and is it transferable?

Most solar panels come with a manufacturer’s warranty that can last 20 years or more. Make sure to ask if the warranty still applies and whether it will transfer to you after the sale.

What are the terms of the lease or agreement if the system is not owned?

If the panels are leased or under a power purchase agreement, review the full contract. Find out how long the agreement lasts, how much the payments are, and whether the lease can be transferred smoothly to a new owner.

How much have the sellers been paying for electricity since installing solar?

Request recent utility bills to understand the actual savings. This can help you see how well the system performs and whether it meets your energy needs.

Is it really worth it to get solar panels for your house?

For many homeowners, yes. Solar panels can lower energy bills, increase home value, and reduce your carbon footprint. However, factors like sunlight, roof condition, and whether you buy or lease panels will impact the overall value. If you plan to stay in the home long-term, they are often a smart investment.
