Solar is now cheaper than it’s ever been, but it’s still a significant upfront cost for the average homeowner.
Luckily, there are many solar financing companies that offer loans, leases, and power purchase agreements so homeowners in the United States can easily make the switch to solar and start saving on their electricity bills.
We put together this guide to help find the best financing company for you.
There are three main solar panel financing options if you don’t have the cash on hand for an upfront purchase: a solar loan, a solar lease, or a solar power purchase agreement (PPA).
A solar loan works like other personal home improvement loans - you take out a loan from a lender for the purchase of the system and make monthly loan payments to pay back the loan.
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 monthly payment is usually lower than what your electric bill would be without solar.

How it works: SunRun is the largest residential solar company in the U.S., installing a new solar system every 2.3 minutes on average. When you take out a loan with SunRun, they take care of all paperwork, permits, design, and installation of your solar installation.
Solar lease/PPA: SunRun offers solar leases and PPAs with $0 down payment and 20-year terms. Their solar leasing payments are a flat payment, whereas the solar PPA payments are based on how much energy the solar panels produce. SunRun will install and maintain the panels - all you have to do is pay your monthly lease or PPA payment.
Solar loan: SunRun’s solar loan, called Bright Advantage, allows borrowers to purchase a home solar system even if they don’t have the money for an upfront payment. Bright Advantage is an unsecured loan, so you don’t have to use your house as collateral. If you qualify, SunRun will partner you with a lender that offers competitive interest rates. You will be responsible for maintaining the system.

How it works: SunPower is one of the most popular solar energy companies in the U.S. SunPower serves as a one-stop-shop for solar solutions: they will assist you in finding an installer, designing a system, and finding financing options.
Solar lease: SunPower solar lease contracts have terms of 20 years, during which SunPower is responsible for all maintenance and repairs. Monthly payments will either be fixed or include a yearly price escalator, which is determined on a case-by-case basis. Solar system performance is guaranteed for 20 years. SunPower owns the system and therefore receives any solar rebates, however, the homeowner can still take advantage of net metering.
Solar loan: SunPower’s zero-down loan has repayment terms ranging from 10 to 20 years, with interest rates as low as 3.99%. Because it is a loan, the homeowner will be the owner of the system, and therefore can take advantage of incentives like the solar Investment Tax Credit (ITC).

How it works: Sungevity acts as the middleman between you and the company financing your system. They will connect you with a finance partner or loan lender that is within Sungevity’s network.
Solar lease: Sungevity’s solar lease payments for a 6.5 kilowatt system would range between $65 to $155 per month, with a 20-year performance warranty. Lease payments will increase each year between 0-2.9%. If the panels produce less than Sungevity’s estimate, they will pay you the difference. The lease provider owns the system and is responsible for repairs and maintenance.
Solar PPA: With Sungevity’s PPA, referred to as their ‘Pay As You Go’ plan, they will connect you with a Sungevity finance partner that owns and maintains the system. The homeowner pays a fixed rate per kilowatt hour of solar power the panels produce. Although the homeowner does not directly get the federal solar tax credit, the savings get passed onto you through a lower per-kilowatt hour rate.
Solar loan: Because Sungevity itself is not a loan lender, there is no set estimate on what kind of terms or interest rates you can expect. However, they will connect you with loan lenders in your area to help you get a competitive rate. When you get a solar loan with the help of Sungevity, you will have 24/7 monitoring of your system through Sungevity, plus a 20-year warranty on the system.
