Installing solar panels for your home is an opportunity to live more sustainability. It’s also a mark of independence, allowing you to generate your power rather than solely relying on the utility company’s grid. Solar panels are also a good investment in the long term, as they can pay for themselves over time by generating electricity from a renewable resource.

Solar panels are more affordable than ever, but the upfront cost is still steep for most people. The average solar energy system costs around $11,000 to $15,000. To cover that upfront cost, you can get a solar panel loan. Multiple lenders offer loans to people interested in installing solar energy systems in their homes.

Most of these loans are unsecured personal loans, which allow you to cover the expenses associated with installing solar panels while letting you pay it off over time — all while the panels save you from the cost of a typical energy bill.

What to look for in a solar loan

When looking for a solar loan, there are a number of factors that you should be paying close attention to. Your needs will vary based on your financial situation and the type of solar energy system you want to install. Still, the loan conditions to look for remain the same:

  • APR and loan terms: Your actual cost when taking out a solar panel loan is dictated by the APR and the loan length. A higher APR and longer loan term will make your total cost higher, though the cost will be spread out over more payments so that the financial stress might be lower.
  • Consider solar-specific loans: Personal loans can be used for various purposes, including installing solar panels. But solar-specific loans may offer additional incentives, including help with financing from the panel manufacturer.
  • Factor in your savings: The goal of installing solar panels, aside from achieving sustainability and reducing carbon footprint, is saving money on your electric bill. Make sure you factor in that savings into the math when considering a loan — and remember you may be able to sell excess energy to the utility company in some cases, too.

Solar panel tax benefits

Another factor to consider when securing a loan for installing a solar energy system is the tax benefits available at the state and federal levels. For federal taxes, an incentive program allows you to deduct 30% of the system’s cost if installed between 2022 and 2032. It will decrease to 26% in 2033 and 22% in 2034.

Similarly, states offer a number of solar incentives designed to encourage homeowners to install solar panels. This will vary by state but typically allow you to deduct between 10-20% of the cost of your solar energy system.

Other types of solar loans

Aside from getting a loan to cover the cost of your solar panels, several alternatives are available to secure the funds needed to fund the project.

  • Cash-out refinance: If you have equity in your home, you can undergo a cash-out refinance, which requires changing the terms of your remaining mortgage while allowing you to turn your existing equity into cash. You will have to pay closing costs on refinancing, which can be steep depending on how much you have left to pay.
  • Credit card: You can pay for the cost of your solar panels on a credit card. However, this payment will be subject to your credit card’s terms, which likely means a high APR.
  • Equipment lease: Some companies allow you to lease solar panels, paying monthly without needing a large up-front payment. The downside is that you don’t own the panels, can’t claim tax incentives, and likely will be paying off the lease for up to 25 years.
  • Financing from solar company: Some solar companies offer financing options that cover the installation cost. These terms usually offer much lower APR but have much longer repayment periods. Interest rates may add up over time.
  • Home equity loan: A home equity loan is a secured loan in which you borrow against the value of your home. It offers a lower interest rate because your home is offered as collateral, but you do run the risk of losing your home if you fail to make payments.
  • Home equity line of credit: Similar to a home equity loan, a home equity line of credit allows you to borrow against the value of your property. However, instead of a lump sum, it is made available as a line of credit that is available as needed. Rates for this may vary and can be higher than a loan.
