U.S. residential solar panel adoption has grown significantly, with about 7% of homes now equipped with solar installations, according to the Solar Energy Industries Association (SEIA). The number of residential solar installations is expected to double to 10 million by 2030 and triple to 15 million by 2034. This shows that household solar energy is becoming more and more popular, and people are increasingly accepting household solar panels. When buying a home with solar panels, one of the most attractive benefits is the potential increase in property value. Homes equipped with solar systems often appeal to eco-conscious buyers and those looking to save on energy costs.
The Pros of Buying a Home with Solar Panels
Reduced Energy Bills
One of the most immediate benefits is the reduction in electricity bills. Solar panels generate electricity from sunlight, decreasing your reliance on the grid and leading to lower monthly utility costs. In some cases, homeowners may even achieve net-zero energy consumption, significantly reducing or eliminating electricity expenses.
Increased Property Value
Studies from the National Renewable Energy Laboratory (NREL) show that homes with solar panels tend to sell 20% faster and for about 4% more than comparable non-solar homes. Buyers are increasingly looking for energy-efficient properties, which positions homes with solar panels as more valuable on the market.
Tax Incentives and Rebates
In many regions, homeowners can take advantage of tax credits and local rebates for having solar systems installed. For instance, the U.S. federal solar tax credit (Investment Tax Credit) allows homeowners to deduct 30% of the installation costs from their federal taxes, making solar homes even more financially attractive.
Energy Independence
Generating your own electricity provides greater independence from the local power grid, enhancing energy security and reducing vulnerability to power outages. This is particularly beneficial in areas prone to grid instability.
Key Factors to Check Before Buying a Home with Solar Panels
Before purchasing a home with solar panels, there are several critical factors to review to ensure you’re making a sound investment. These considerations can affect the system's performance, ownership responsibilities, and long-term benefits.
Who Owns the Solar Panels?
If the system is owned by the current homeowner, it will transfer to you upon purchase, and you’ll enjoy the full benefits of lower energy bills without additional payments. However, if the system is leased or financed, you may need to assume the existing lease or loan agreement.
Leased systems, in particular, can complicate the sale of a home. According to a report by the U.S. Department of Energy, some buyers may be hesitant to take on a solar lease, potentially slowing down the sale process. If the panels are leased, carefully review the contract to ensure it’s manageable for your situation.
Who Installed the Solar Panels?
If the panels were installed by a certified solar installer, the system is covered under a manufacturer’s warranty. Most certified installations come with warranties that last between 10 and 25 years for the panels, inverters, and other components.
If the system was installed as a DIY project, the warranties may be voided, leaving you responsible for any repairs or replacements. Be sure to ask for documentation on the installation and check if the installer is recognized by organizations like the North American Board of Certified Energy Practitioners (NABCEP), which certifies high-quality solar installations.
How Old is the Solar System?
Solar panels typically have a lifespan of 20 to 25 years, and their efficiency decreases slightly each year. If the system is nearing the end of its lifespan, it may not provide the full energy savings expected.Before buying, verify the age of the solar panels, and if they’re approaching their expiration date, consider the cost of replacing or upgrading the system in the near future.
How Much Energy Does the System Produce?
A key consideration is the solar system’s energy output. You can request data from the homeowner or their utility company on the system’s historical energy production to see if it meets your household’s energy needs.
The National Renewable Energy Laboratory suggests that a properly installed solar system should generate around 1,500 kWh per year for every kilowatt of installed capacity. Compare this output to your current or projected energy usage to determine if the system will effectively reduce your electricity bills.
What is the Current Condition of the Roof?
If the roof was in poor condition before the panels were installed, or if the installation caused any damage, you could face costly repairs down the line. Have a professional inspector assess the roof's condition to identify any potential issues.
If the roof needs to be replaced soon, the panels will need to be removed and reinstalled, adding to the expense. Make sure the roof has at least as long a lifespan as the solar system.
Are the System Components Still Under Warranty?
Solar systems come with warranties that cover various components, such as the panels, inverters, and mounting hardware. Panels generally have 20-25 year warranties, while inverters might only be covered for 10-15 years. Make sure to verify which parts of the system are still under warranty. Having coverage can save you significant costs if any components fail or need replacement after the purchase.
Warranties also provide peace of mind that the system will continue to operate effectively, ensuring that your investment remains sound. Always ask for copies of the original warranty documents to understand the coverage and its limitations.
Conclusion
Buying a home with solar panels can offer significant benefits, from reducing energy bills to increasing property value, and even contributing to environmental sustainability. With proper research and due diligence, purchasing a solar-equipped home can be a smart investment that delivers both financial and environmental rewards.
