Top 6 solar financing companies

Find out what solar panels cost in your area

The easiest and most cost-effective way to get solar is to pay off your entire solar panel system in cash. However, this isn’t possible for many homeowners since solar systems can cost tens of thousands of dollars.

That’s where solar financing comes in. Financing options like solar loans let you gradually pay off your system in monthly payments. According to the U.S. Department of Energy, about 85% of residential solar systems in the U.S. are financed. 

Many times, homeowners find financing through companies that specialize in solar loans. Finding the right financing company can be tricky, but we’re here to help. 

With the help of hundreds of solar installers, we were able to narrow down six of the most popular solar financing companies: 

  • Mosaic

What is a solar loan?

Solar loans are the most popular way to go solar. Borrowers can secure a loan from solar financing companies, typically via their solar installer, that covers the amount needed for a home solar system.

Solar loans are structured pretty similarly to any other type of loan but have a few key features you should be aware of, including:

  • Dealer fees

  • Interest rates

  • Term lengths

  • Balloon payments

  • Down payments

  • Monthly payments

Financing solar usually starts with some type of application process. Once the borrowed amount is finalized,  you’ll have a monthly payment to the financing company.  The monthly payment will comprise of principal and interest, as well as additional fees. You can pay through a checking account or credit card, typically via online banking.

Solar loans typically have interest rates of around 6% but vary quite a bit depending on your FICO credit score, the installer you choose, and any dealer fees involved. The term length of your loan also determines your monthly payment. Most solar loans range between 15 to 20 years to pay back, but 25-year loans are becoming increasingly common.

Solar tax credit and solar loans. The federal solar tax credit is the most popular solar incentive available today. Most solar loans require you to pay the value of your tax credit to the financing company no later than 18 months after you start loan payments. If you don’t pay the value of your 30% tax credit, your loan payments will increase after 18 months.

What other solar financing options are available?

Other solar financing options exist if you can’t pay in cash or take out a loan. 

These are called solar leases and power purchase agreements (PPAs). With solar leases and PPAs, you don’t have to pay any upfront costs. Instead, a solar developer owns the system on your roof, and you submit a monthly payment to them for using the energy the solar panels create. The solar payment is usually cheaper than your monthly electric bill without solar.

For solar leases and PPAs, most incentives and rebates, such as the 30% federal tax credit, are entitled to your solar developer, not you.

Going solar with a lease or a PPA does save you money upfront, but they usually result in lower long-term savings than if you purchased the system with cash or a loan.

Popular solar lease and PPA companies: SunPower and Sunrun

If you’re curious about solar leases and PPAs, you’ll probably want to look at SunPower and Sunrun.

Sunrun is considered one of the pioneers in third-party-owned solar systems. Its PPA and lease offerings include a full-coverage warranty and no money down on solar systems. When leasing through Sunrun, you are given a performance guarantee that your solar system will never operate below 95% of the estimated energy output. If your panels produce below 95%, Sunrun will refund you the difference. The average cost of financing through Sunrun is $4.50 per watt.

SunPower third-party-owned systems also have a production guarantee that varies depending on your system. SunPower’s responsibility to your system includes maintenance, insurance, and monitoring. The average cost of financing through SunPower is $4.89 per watt, but it uses premium-level products and often comes with better customer service than Sunrun.

Solar loans are the best option for most homeowners. However, rising interest rates and dealer fees make loans way more expensive, making solar leases and PPAs look more attractive to homeowners than they have in the recent past. In general, though, you can still get a better return on your investment by using a solar loan. 

Solar leases and PPAs are the best choice if you want to go solar, but you can’t qualify for a loan or the federal tax credit. Maybe your credit score isn’t great, or you don’t have taxable income. A lease or a PPA can be the best choice in either of these scenarios. 

You can also seek personal loans, like a home equity line of credit, to pay for your solar system. Depending on your finances, you could get a lower interest rate than you could through a solar loan provider, and you wouldn’t have to worry about dealer fees. However, personal loans come with their own rules, so make sure you understand all the costs and benefits before you choose this route.

We recommend getting quotes for both the cash purchased price and the financed price offered by a solar installer so you can get a sense of which financing option is best for you - getting your own financing or taking the solar loan.

Solar financing: Red flags to look out for

Investing in a solar system is a huge financial decision, and finding the right company can seem pretty labor-intensive. To help you narrow it down, here are a few things you should avoid when financing your solar system.

  • High interest rates and dealer fees: Dealer fee percentages are higher if your interest rate is low. You should run the numbers if both your interest rate and your dealer fee are high. It might not be a good deal, and you may want a personal loan or HELOC to pay for your solar system

  • Claims of “free” solar panels: If any financing company you use advertises solar loans as “free solar panels”, this is a major red flag. There is no such thing as free solar panels. This is a common sales tactic to lure in customers with no upfront costs. One thing is for sure: you will have to pay for solar one way or another. 

  • A low minimum credit score requirement: When it comes to financing, you’ll need a good credit score to be lent money. Companies that hand out money with a low or no minimum credit score might have high-interest rates or fees that could result in an issue for you to make monthly payments. This is a large reason why PACE financing has gotten a bad reputation.

Finding the right solar financing company

To find the right financing company for your solar energy system, you first need to find the right solar installer. 

We advise anyone interested in switching to solar to get quotes from multiple local solar companies and check out their reviews on SolarReviews to see what solar installer is best for you.
