Buying a house is a big step. You’re not just choosing where to live, but also how you’ll power your home. Today, many houses come with solar panels. This means they use energy from the sun to make electricity.

It’s cool because it can save money and help the planet. One fact about this topic is that owning solar panels might add up to 4% value to your home.

Our article will guide you through everything you need to know if you’re thinking about buying a house with solar panels. We’ll cover important questions to ask, the pros and cons, and how solar impacts things like your mortgage and home’s resale value.

Essential Questions to Ask Before Buying a Home with Solar Panels

Asking the right questions about solar panels can guide you to make a smart choice. Keep reading to learn what those key questions are.

Who owns the solar panels?

Sellers might not own the solar panel system even if it’s on their roof. Always ask about ownership before buying a house with solar panels. It’s essential to know if the panels are owned outright or under a lease or power purchase agreement (PPA).

Ownership affects your property taxes, options for financing, and how you can use and maintain the system.

Find out who owns the solar panels as your first step. If they are leased or part of a PPA, understand the terms. This includes knowing how long the lease lasts and if there are any costs to take over the agreement.

Owned solar panels can increase a home’s value and offer more freedom in usage and maintenance but check all details first.

Who installed the solar panels?

A professional installation company usually puts in the solar panels. This is key for buyers to know because it can affect quality and warranty. The company can give important details about the system’s condition, maintenance needs, and energy production.

Asking for the installer’s name lets you check their reputation. You can see if they have good reviews and if they follow standards. This helps ensure the panels are set up right and will last a long time.

What is the condition of the roof?

Checking the roof’s condition is key when buying a house with solar panels. Roofs in poor shape or covered by trees might not be right for solar panels. It’s smart to see if the roof can hold up under solar panel weight and last as long as the panels do.

Find out if there are any signs of damage or wear that could cause problems later on. Ask about recent repairs or replacements to make sure the roof is ready for solar installation.

This step ensures your home stays safe and maximizes the benefits of solar energy.

What are the maintenance needs?

After ensuring the roof’s condition can support your solar panels, it’s vital to understand their maintenance requirements. Solar panels typically need care two to four times a year.

This routine varies based on location and specific panel types. Most often, they require cleaning to remove dirt and debris that accumulates over time. Regular upkeep is essential for maximizing efficiency and power output.

If the home has leased solar panels, the good news: the leasing company usually handles all maintenance needs. You won’t have to worry about scheduling cleanings or fixing any issues yourself.

For homeowners with purchased panels, understanding how to maintain them properly becomes crucial for long-term savings on energy bills and keeping emissions low.

What is their average output versus the home’s average usage?

Solar panels on a house aim to cover most or all of the home’s energy needs. The number of panels installed usually matches the average electricity use of the house. This means if a home uses around 900 kilowatt-hours (kWh) per month, the solar panel system will be designed to generate close to this amount.

To find out if the system meets your needs, compare its average output with your expected usage. If you have an electric car or plan to install a solar-powered water heater, your energy needs might increase.

Knowing how much power the panels produce helps you understand if they will fully support your lifestyle or if you’ll still rely on the grid for some electricity.

What is the production guarantee?

A production guarantee is a promise from solar panel companies. It assures you that the panels will produce a certain amount of energy over time. If they don’t meet this promise, the company will pay you back for the difference.

This makes buying a house with solar panels less risky.

Most warranties cover both the performance and longevity of the panels, helping reduce your carbon footprint without worry. Knowing there’s a safety net encourages more people to switch to renewable energy.

Now let’s explore purchasing a home with solar panels: pros and cons.

Purchasing a Home with Solar Panels: Pros and Cons

Buying a house with solar panels can save you money on electricity bills. But, it also means considering their maintenance and the roof’s condition.


Owning a home with solar panels can lead to big savings on energy bills. Homes with these systems sell for 4.1 percent more than those without. This makes solar homes a smart investment.

Solar power reduces the need for electricity from the grid. It cuts down on greenhouse gas emissions too.

Solar panel owners enjoy long-term savings and renewable energy benefits. Consumer Reports says buying a house with owned solar panels saves more money than leasing them. These houses offer lower electric bills and less dependence on utility companies.

Solar energy is clean, reducing your carbon footprint while saving money each month.


Buying a house with solar panels might bump up the home’s value if you own the system, but not so much with a power purchase agreement (PPA). This can make selling your home more complicated.

The initial cost of a solar setup isn’t small either. You might face high upfront costs for the solar system itself. Plus, energy production drops on cloudy days or during winter months because solar energy needs sunlight to work well.

Also, keep in mind that financed solar panels could tangle up the home-selling process. You’ll need to sort out who owns the system and any loan agreements attached to it before you can sell your house.

Financing and closing on a home with solar panels can affect overall costs and complicate things further.

Next comes “The Impact of Solar Panels on Mortgage and Resale Value.”

The Impact of Solar Panels on Mortgage and Resale Value

Homes with solar panels can sell for about 4% more than homes without them. This bump in price is because solar panels provide long-term energy savings, making these homes more attractive to buyers.

Studies by Zillow confirm that not only do these homes fetch a higher selling price, but they are also more likely to be sold compared to those lacking solar installations.

For homeowners thinking of refinancing or taking out a mortgage, having solar panels could play a favorable role. Lenders like Rocket Mortgage see the added value in energy-efficient upgrades like rooftop solar systems.

This means you might get better loan terms due to the increased home value from your solar setup. Solar-powered houses stand out in the real estate market, offering both financial benefits and an edge over properties without renewable energy sources.


Buying a house with solar panels offers unique advantages like lower utility bills and potential tax benefits. Ask the right questions about ownership, condition, and efficiency to make a smart choice.

Consider both the pros and cons to see how they align with your needs. Solar panels can increase home value, but understanding all aspects ensures you’re making the best investment for your future.

Always consult with experts to help guide your decision in this exciting step towards sustainable living.
