What Are the 3 Most Common Solar Panel Financing Options?
When buying solar panels, there are generally three ways for homeowners to pay for their systems from a solar company: cash, loan or lease. Although paying for your solar panels in cash upfront will maximize your savings and allow you to start saving on your energy bills right away, it’s not a realistic option for most homeowners. Instead, many homeowners take out a loan to finance their solar panels. With a good solar loan, homeowners will still see energy savings and be able to pay off their solar panels over time. Just make sure that your loan conditions, including origination fees and the interest rate, are suitable.
We do not recommend solar leases for most homeowners. Unlike paying for your panels in cash or with a loan, with a solar lease, you will not own your solar panels. Instead, you will be paying monthly “rent” for your solar equipment.
So which solar financing option is best for you? Keep reading to learn more about the pros and cons of each.
SunPower designs and installs industry-leading residential solar and storage solutions across all 50 states. With a storied history of innovation dating back to 1985, no other company on this list can match SunPower’s experience and expertise.
SunPower earns its position as the top national installer on our list for a handful of reasons: It installs the most efficient solar technology on the residential market, offers the most expansive service area and backs its installations with a warranty well above the industry standard. All the while, SunPower pioneers sustainability efforts within the industry.
If that weren’t enough, SunPower systems come packaged with products all manufactured in-house by its sister company, Maxeon. This means that your panels, solar cells, inverters, battery and EV chargers are designed to work together and are all covered under the same warranty.
SunPower’s biggest downside? Its high-efficiency panels are considerably more expensive than most of its competitors’ products. However, its powerful panels are workhorses that make up for the initial cost with more backend production (think about this like spending more money for a car that gets more miles per gallon).

Blue Raven Solar
We like Blue Raven Solar because it understands that, for most homeowners, the cost of solar presents the biggest barrier to entry.
For that reason, Blue Raven Solar developed an innovative solar financing plan that offers in-house, flexible, zero-money-down options. The results speak for themselves, as Blue Raven Solar is now one of the fastest-growing solar companies in the nation and was recently acquired by SunPower. Its BluePower Plus+ plan (exclusive to Blue Raven) mimics the flexible structure of a lease while still providing the greatest benefits of owning your system.
Eligible homeowners enjoy 18 months of solar power before having to pay their first bill. When coupled with the federal solar investment tax credit (ITC), the initial energy savings can offset more than a third of the overall cost of a system before requiring a dollar down.
In contrast, other installers can only offer similar financing through solar leases, PPAs or third-party providers (such as Mosaic or Sunlight). Third-party loan providers can complicate the process, while opting for a loan or PPA will disqualify you from some of solar’s biggest benefits (additional property value, federal solar tax credit and local solar incentives).

ADT Solar sets the industry standard for warranty coverage by including a multifaceted guarantee, making it one of the top installers for homeowners who want added peace of mind.
Its warranty coverage includes all of the following for 25 years:
- Power Production Guarantee: Also known as a performance guarantee, this ensures your solar system will produce the amount of electricity that’s outlined in your proposal, or ADT will write you a check for the difference.
- Labor Guarantee: This covers any issues with the installation of your system and is also known as a workmanship warranty.
- Panel Module Performance Guarantee: This is what ADT Solar refers to the manufacturer warranty as, and it ensures that any manufacturing defects are repaired or your ineffective panels replaced.
- Enphase Microinverters Guarantee: This backs the performance of your inverters.
Though in recent years other solar companies have started to offer similar guarantees, ADT Solar has been at it since 2008, performing over 30,000 installations across the country.

Paying for Solar Panels in Cash
For homeowners who wish to maximize their savings, paying in cash is the optimal way to go. After all, by buying a residential solar power system outright, you’re essentially paying in advance for 25 to 30 years of electricity to use in your home.
This means your home energy rates are locked in for decades, and you don’t have to worry about inflation or rising utility costs. The big problem with paying in cash is that the upfront system cost of solar power equipment tends to be fairly high.
Even when you take into account incentives like federal tax credits and rebates, you’re looking at an investment of at least $10,000 to $15,000. This isn’t going to be feasible for every homeowner.
Solar Panel Loans
Another option is to borrow money from a solar lender, using it to finance your solar installation, then paying it back over time. The most common types of solar loans include unsecured personal loans, home equity loans (or home equity lines of credit), home improvement loans, and in-house financing through your solar panel installation company.
If you choose a loan as your solar financing route, pay special attention to your annual percentage rate (APR), origination fees and loan terms. How much you pay in interest, fees, and your repayment period will often increase the overall cost of your renewable energy system.
However, rest assured that homeowners who finance their systems with a loan are still eligible for the federal government’s solar investment tax credit (ITC), which may make it a bit easier to pay off that loan. Some states and local governments have low-interest rate loan programs for clean energy systems that you can take advantage of, such as Property Assessed Clean Energy (PACE) loans.
Borrowers sometimes have solar programs as well, like Fannie Mae’s HomeStyle® Energy mortgage. If you’re interested in paying for a solar installation via a loan, make sure you research all low-interest financing options available to you.
Additionally, with congress recently passing the Inflation Reduction Act, there will be a significant expansion in government loans for solar energy systems.
Leasing Solar Panels
Homeowners may also choose to either lease their solar panels or participate in a power purchase agreement (PPA), through which you buy the electricity the panels on your roof are producing. Solar leases and solar PPAs are pretty similar, but with one significant difference:
A solar lease means you’re making fixed monthly payments to use solar panels and other solar equipment, whereas a PPA means you’re making monthly payments simply for the electricity produced by solar panels. Naturally, the amount of electricity may fluctuate quite a bit from month to month.
Solar leases can seem attractive at first, but for most homeowners, they don’t make much financial sense. One reason for this is that homeowners in PPAs or leases are not eligible for the federal solar tax credit. Another thing to note is that solar leases don’t enhance your property values, which can be one of the big financial incentives of a residential solar system. Other financing options will allow you to save a lot more money in the long run.

How Do These Solar Financing Options Compare?
Solar panels can be expensive, and deciding whether to pay with cash, choose solar financing or sign a solar lease can be confusing and a bit stressful. The short answer is that all of these options have their upsides and drawbacks, so it’s up to you to decide which is right for you.
Generally speaking, cash purchases are the best option because they save you the most money in the long run. Solar loans are a great alternative, and signing a solar lease should typically be avoided, although they do have their place in the solar industry.
In the following sections, we’ll explain some of the pros and cons of the different solar financing and payment options to help you decide which options work for you and which don’t.
Paying in Cash: Pros & Cons
As you can see in the chart above, paying cash for your solar panels provides the greatest long-term value. However, it also requires the most significant amount of money upfront, so many people are unable to go this route.
The average cost of solar panels is around $23,940 before the federal solar investment tax credit (ITC) or $16,758 after the 30% credit is applied. This is assuming the national average cost of solar panels of $2.66 and the average solar system size of 9 kilowatts (kW).
If you’re able to afford this upfront cost, you stand to save thousands of dollars that would otherwise cover the interest over the lifetime of a solar loan. Paying in cash also allows you to begin saving money right away with your solar production rather than waiting for your monthly energy savings to cover your loan payments. Below, we’ll include some pros and cons of paying for your solar system with cash.
- No interest paid, meaning lower overall costs
- Start saving money right away on your monthly electric bills
- Maximize your return on investment (ROI)
- Take advantage of solar tax credits
- Boosts your home value
- High upfront cost
Financing Solar Panels: Pros & Cons
Most homeowners choose to finance their solar power systems rather than pay with cash due to the high upfront cost of installing solar. Solar panel loans let you defer the total price of your solar panel system and pay it back over a period of several years, usually between five and seven years.
The primary downside to this option is that you’ll end up paying interest every month, which means you stand to save less over time than if you paid with cash.
Of course, solar loans come with major upsides, too, like far less money required upfront, which has lowered the barrier to entry for most homeowners. Those who purchase a system via a loan still maintain eligibility for solar tax credits, including the federal solar tax credit. We’ll briefly list the benefits and drawbacks of securing a solar loan below.
- Minimal money required upfront
- Lower barrier to entry than a cash purchase
- Allows you to invest your money elsewhere
- Still lets you take advantage of tax credits
- Boosts your home value
- You’ll pay interest on your loan, which prolongs your solar payback period
- You’ll end up paying more for your system over time
Leasing Solar Panels: Pros & Cons
Solar leases were once a popular option because they require little to no money down and still let you support the adoption of clean energy sources. However, they’ve increasingly become considered a last-ditch effort to convert to solar for many homeowners because they typically save you the least amount of money.
Solar leases also tend to be sold by less reputable companies trying to make a quick buck. The majority of complaints toward solar companies come as a result of low-quality solar leases.
Here’s another key disadvantage of leasing your system: The company you lease from maintains ownership of the panels, which means it cashes in on any available tax credits and rebates rather than you benefitting from them.
Because you don’t own the system, solar leases also won’t add to your home value like solar loans and cash purchases do. In fact, solar leases can complicate the process of selling a home, as not all home buyers will want to assume the lease, and it can cost thousands of dollars to terminate your lease early.
- No down payment required
- Minimal barrier to entry
- Allows low-income families to support clean energy
- No maintenance required
- Doesn’t increase your home value
- Can complicate the process of selling a home
- You lose eligibility for solar tax incentives
- Sometimes sold by unethical companies
- Often come with hefty cancellation fees
Before we move on, let’s take another look at the biggest advantages and disadvantages of each option.
Which Solar Panel Financing Option Is Right for You?
Ultimately, the way you choose to pay for your solar panel system will depend on a number of factors, including your expendable income, your credit score and ability to get a good loan rate, and more. Here’s a breakdown of which type of solar panel financing may be right for which homeowners:
|Solar Financing Option||Who it May Be Right For|
|Solar lease or PPA||
What’s a Good Interest Rate When Financing Solar Panels?
Solar loan interest rates typically range from around 3.99% to up to 16.99% (with the highest interest rate possible being 24.99%). As is the case with any loan, the lower your interest rate, the better the deal and the less money you’ll pay in interest over time. Lower interest rates help reduce your repayment timeline, ultimately allowing you to save more money in the long run.
The average interest rate for a solar loan is between 3.99% and 5.99%, so we recommend searching for an interest rate below 6%. We’ll discuss some tips for reducing your APR below.
Is Interest From Solar Loans Tax Deductible?
Yes, interest from solar loans is tax deductible, so going solar with solar financing will benefit you when it’s time to do your taxes.
Installing solar equipment — provided you don’t opt for a solar lease — is considered a capital improvement, so it will bump up your home value. Since all capital improvement payments and interest charges are considered tax deductible by the IRS, your solar loan interest will also be tax deductible.
Many states also have sales and property tax exemptions on solar equipment, meaning your property taxes will not increase after solar installation despite it being an improvement. Solar sales tax exemptions can also shave a few thousand dollars off of your installation if you live in a state with sales tax.
Taking advantage of these tax incentives can be a bit confusing, but tax programs — like HR Block and TurboTax — or an accountant can help guide you through the process to ensure the maximum savings on your investment.
Which Banks Are Best for Solar Loans? (And Where to Apply)
Countless lenders now offer solar loans, so you’ll have plenty of options to choose from. In many cases, your solar installer will have relationships with specific solar loan providers, but you can always choose an outside lender for your solar system. As such, it’s wise to shop around and see which company offers you the lowest solar loan rate and the best terms.
We recommend applying to one or two of the big names that service your area in addition to the companies your solar installer offers. This way, you get a better sense of the options available to you.
We’ll include some information on specific banks for solar loans below, as well as some tips for finding the lowest rate available.
Best Solar Financing Banks
The most popular solar loan providers in most areas throughout the country include Mosaic, LightStream Financial, Sunlight Financial and GoodLeap. These companies have relatively low credit score requirements and can lend between $1,000 and $100,000 for your solar system, depending on your home and eligibility.
You can also turn to the bank or credit union you use for your checking or savings accounts. Many major banks and lenders — including Chase and Bank of America — don’t offer solar-specific loan products, but others — like Wells Fargo and Fannie Mae — do.
You might be eligible for a lower interest rate or more appealing terms if you choose to finance your solar panels with your primary banking institution.
How to Apply to Get the Best Rates
Just like when buying a house, it’s important to get as low an interest rate as possible on your loan. Lower interest rates can make the difference of several thousand dollars in the long run. There are a few things you can do to land more appealing solar loan terms.
- Improve your credit score: Lenders look favorably on borrowers with higher credit scores, and they’re often willing to provide a lower APR to those individuals. It might take some time, but improving your credit score — especially if you’re in the 600-700 range — can do wonders for your solar loan interest rate. To do this, you can pay off credit card debt and ensure you’re not missing any monthly payments.
- Shop around rather than settle for the first rate you get: Different lenders have varying tolerances for risk, which means one lender might offer you a significantly lower rate than another. We recommend getting two or three APR estimates from different top lenders to see which one can serve you best while saving you the most money.
- Choose a secured loan over an unsecured loan: A secured loan, sometimes called a home equity loan or a home equity line of credit (HELOC), utilizes collateral — meaning you’d borrow money against the value of an asset like your home — as a guarantee that you’ll make your monthly payments. Secured loans show you have more “skin in the game,” which lenders see as a sign of commitment and will often lower interest rates for.
- Offer a higher down payment: For the same reasons mentioned above, a higher down payment shows your lender that you’re committed to owning your solar system. Interest rates tend to drop as down payments increase.
- Opt for a fixed interest rate over variable loan options: Loans with fixed interest rates are more predictable and generally a better option than variable rates.
- Have someone co-sign your loan: A co-signer agrees to secure your loan using their own credit score and reputation, so having a co-signer with a high credit score and good credit history is likely to land you a better rate.
How Long Is a Typical Solar Loan?
Like all other loans, solar loans can vary quite a bit in their length. Most fall between 10 and 20 years, but you could find a lender for a three-year loan or a 30-year loan, depending on your specific situation.
The average length of a solar loan is around 15 years, which is longer than most solar systems take to pay for themselves. Keep in mind that longer loan terms tend to decrease your interest rate, but they also lead to higher overall payments for your system.
What Credit Score Do You Need for a Solar Loan?
Generally speaking, you’ll need a credit score above 550 to secure a solar loan. However, there are exceptions to that rule of thumb, and your loan approval or denial is really based on your individual situation.
We’ll explain what you can reasonably expect as far as an interest rate and overall loan experience based on different credit scores below.
Solar Financing for Credit Score Below 550
If you have a credit score below 550, you’re very likely to have some trouble securing a solar loan. You might be able to find a lender who will make an exception, especially if you provide collateral for the loan — via a secured solar loan — and offer a large down payment.
However, at this credit score, it’s likely a better option to opt for a solar lease or, better still, to work to improve your credit score before applying for a solar loan.
Rates for Credit Scores Between 550 and 650
If your credit score is between 550 and 650, you shouldn’t have too much of an issue finding a mainstream lender to approve a loan for you. Lenders like Upgrade, PenFed, Alliant, BestEgg and LightStream have been known to approve loans in this range.
Keep in mind that if your credit score is in this range, your APR on a solar loan will likely be above the average of 6%.
Financing Solar With a Credit Score of 650+
Once your credit score surpasses 650, you’ll have many options available to you and no shortage of lenders that will approve loans at reasonable annual percentage rates.
In addition to the companies mentioned in the previous credit score range, a 650+ credit score will open you up to loans from SoFi, Mosaic, Discover, SunLight Financial, SunPower Financial and GoodLeap.
Your APR will likely be under 10%, with higher credit scores moving you closer to the 6% average or the lowest rates around 4%.

How Can You Save Money When Going Solar?
While the initial solar investment can be steep, there are options available to homeowners who wish to save money on their solar installation.
- Federal solar tax credit: Currently, installing a solar system qualifies you for a tax credit that’s worth 30% of the total equipment and installation cost.
- Local utility rebates: Many municipal utility companies offer rebates (such as a property tax exemption) to homeowners who go solar. Research your local utility providers to learn more.
- Net metering: Also see if there is a net metering program available in your area. Net metering gives you the opportunity to funnel any surplus energy you generate back into the electrical grid, in exchange for a credit from your utility company.
- Shopping around: Finally, remember that not all solar installers are created equal. Shop around and compare quotes to ensure you’re getting the best value.

Wrap Up: Is Financing Solar Panels Worth it?
As we’ve mentioned, purchasing solar panels with cash upfront will provide the best long-term returns — but we understand that won’t be feasible for most people.
However, for many homeowners, financing solar panels is absolutely worth it. With a solar loan, you get all the same perks of system ownership that you would if you paid in cash but with a minimal down payment — or none at all. Think about it as renting-to-own.
Here are a few of the biggest advantages of financing a system:
- Minimal or zero money down
- Maintains eligibility for the federal tax credit and local rebates
- Boosts your property value
Financing your solar panels will require you to pay more in the long run than you would with cash, as you’ll have the total system cost plus the interest you pay on your loan. However, most homeowners repay their loans within five to 10 years using the energy savings provided by their solar panels.
In closing, solar financing has become an excellent way to convert to renewable energy, minimize your upfront payment and still receive all the tax incentives and energy-saving benefits that come with owning a system.
