Whether you're hoping to save money each month, decrease your eco-footprint, or increase the value of your property, solar panels -- and a personal loan -- can help. Here, we'll discuss the cost of solar panels, how the best personal loans work, and other options for covering the unwelcome expense.

How much solar panels cost

According to EnergySage, the average U.S. home requires about 11 kilowatts (kW) of home solar to cover its electricity usage. That means homeowners pay just shy of $21,000 to install a system after federal tax credits.

Getting a solar panel loan

Personal loans can be an ideal way to fund solar panels. Solar panel loans allow homeowners to pay off the cost of a solar panel installation over several years rather than paying out of pocket.

How a personal loan for solar panel loans work

A personal loan is money you borrow from a lender and repay with interest, typically in monthly installments. There are two types of personal loans -- unsecured and secured. An unsecured personal loan means you don't have to put up collateral for the loan. A secured loan requires you to put something of value up as collateral.

Pros and cons of personal loans

If you're considering a personal loan to purchase solar panels, it's wise to weigh the pros and cons.

Pros

  • You may be able to borrow the entire amount required to install solar panels.
  • Since personal loans may be secured or unsecured, you can choose which type of loan works best.

Cons

  • You must pay interest on the loan, and if your credit score is low, your interest rate may be high.
  • You'll need to work a new monthly payment into your budget.
  • If you decide to take out a secured loan to qualify for a lower interest rate, you risk having the asset used as collateral repossessed if you miss payments.

Take the time to decide whether it's the right move to take out a personal loan to cover the cost of solar panels, based on these points.

Getting a low-interest solar panel loan

As with all loans, the goal is to land the lowest possible interest rate. Here are some of the factors that go into deciding your rate.

Your credit score

The higher your credit score, the better your chances of landing a low interest rate. If your credit score is on the low side, consider taking steps to boost it before applying for a loan, such as paying down debt and checking your credit reports for errors.

Employment and income

Lenders routinely ask for proof of employment status and how much money you earn. When checking your income, they want assurance that you can afford monthly payments.

Secured or unsecured

Taking out a secured loan means putting something of value up as collateral. However, it also means you risk losing the collateral if you miss payments. Still, because lenders know there's a valuable asset on the line (meaning less risk to them), you're likely to be offered a lower interest rate.

Your repayment timeline

Lenders consider longer-term loans riskier because there's more time for things to go wrong. They offset the additional risk by charging a higher interest rate.

The workaround is to choose the shortest loan term you can afford to repay. Not only will you be rid of the loan sooner, but you'll likely pay a lower rate and less interest overall.

How to apply for a solar panel loan

Here's how to apply for a personal loan.

1. Check your credit score

High credit scores are rewarded with lower interest rates and loan fees. Before proceeding, check your credit score and order a copy of your credit report. If it's low, take steps to raise it.

2. Decide how much you want to borrow

Work with your contractor to learn how much money you'll need upfront to pay for your new solar panels.

3. Rate shop

Check several lenders, remembering that interest rates only tell part of the story. Also, look at the APR, which includes interest, fees, and other charges. If a potential lender conducts a hard credit inquiry during the prequalification process, your credit score may drop by a few points. However, making regular, on-time payments will help your score to rebound.

5. Decide on a lender

Complete a full loan application after you've shopped lenders and know which offers the lowest APR and best repayment terms. Once approved, read over the loan agreement and ask questions of the lender if there's anything you don't understand. Sign the loan agreement, await loan proceeds, and get ready to make your first payment approximately one month later.

Alternatives to a personal loan

Taking out a personal loan is not a one-size-fits-all solution. Here are two other options worth exploring.

Government loan

The FHA's PowerSaver Loan from the Federal Housing Administration allows homeowners to finance cost-effective, energy-saving improvements, including solar and renewable energy systems in their homes. You can borrow up to $25,000 for as long as 20 years.

Home equity loan

A home equity loan allows you to borrow money from the equity in your home to finance renewable energy. Because your property serves as collateral, you are likely to snag a decent interest rate. But remember: It also means the bank has the right to repossess your home if you fail to pay the loan.

A note about solar leasing: If you decide to lease solar panels rather than purchase them, ask questions -- lots and lots of questions. Here's why: You cannot claim solar tax credits when you lease solar panels. Despite what you might be told during a sales pitch, the company that owns and leases the panels gets all tax savings. Allowing someone to make money from you while also reaping the benefits of tax credits negates one of the most substantial benefits of going solar.

Final thoughts

When deciding how to finance solar panels, you may be nudged toward one type of lender or another. Do not rush into a solar loan. If you decide to move forward with the purchase, let your salesperson know that you plan to rate shop first.

A difference of as little as one percentage point in interest can save you (or cost you) thousands over the life of your solar loan.

FAQs

  • You decide how much to borrow. However, the more you borrow, the more interest you'll pay -- and those interest payments may be better used elsewhere, like building your nest egg.

  • Your credit score impacts whether you're approved for a loan and determines how much you'll pay in interest and loan fees. Boosting your credit score is not only a great personal accomplishment, but it can also save you thousands of dollars over your lifetime through lower interest rates.

  • According to Boston Solar, breaking even on upfront costs typically takes between eight and 12 years, although the numbers can vary dramatically. It depends on factors like how much you spend on the initial solar installation, the cost of electricity in your area, and the credits available to you.
