How to Buy Solar Panels

Buying solar panels is something homeowners do once, maybe twice, in a lifetime. As such, the process can be a little intimidating and it can be tough to know where to begin.

So, in this article we’ll break down the basics of buying solar panels for your home. We’ll cover:

Let’s jump right by exploring the two main ways to buy solar panels.

How to buy solar panels: Cash vs loan

If you plan to buy solar panels, one of the first things to consider is whether you’ll purchase them with cash or finance them with a loan.

While a cash purchase leads to greater lifetime savings, financing with a solar loan can lead to more immediate savings. Typically, about half of customers chose to pay cash and the other half chose to finance with a solar loan.

Cash advantages Loan advantages
Greater lifetime savings More immediate savings
No interest payments Zero down payment
Not subject to loan approval qualifications Steady, predictable electricity costs

In the example below:

  • Paying cash (purple line) leads to ~$4,500 in additional energy cost savings, but it takes around 7 years to break even
  • The 12-year solar loan (pink line) offers immediate monthly savings, but includes ~$4,500 in interest payments

How you choose to buy solar panels depends on your financial situation and your savings goals.

Buying solar panels with cash

Paying cash is the simplest way to buy solar panels and offers the greatest return on investment. Cash purchases are typically made in 3-4 installments.

For example:

  • Down payment/deposit – An initial deposit upon signing a contract in order to lock in an installation date
  • Due upon delivery of materials – A second installment around 50% of the remaining balance is due when equipment is delivered and/or installation begins
  • Due upon final inspection – The remaining balance is due once your system is installed and passes city building inspection

Of course, the exact payment schedule varies by installation company, but now you have a basic idea of what to expect.

While cash provides the greatest long term cost savings, there is typically a 6-10 year payback period before you recoup your upfront investment. Given that solar panels are warrantied for 25 years (and last much longer) that leaves plenty of time to accumulate savings.

Buying solar panels with a loan

Let’s face it, not everybody has $20,000 to $30,000 in cash laying around – but that doesn’t mean you can’t buy solar panels.

Solar loans offer a steady monthly payment that can front-load your solar savings. For example, if your average electricity bill is $125 a month and your solar loan payment is $100 a month, you’re saving $25 a month ($300 per year) right off the bat.

The great thing about solar loans is that they are incredibly versatile. There are two types of loans – combo and reamortizing – and loan terms range from 8 to 20 years. In addition, most solar loans do not require a down payment, although you can make one to lower your monthly payments.

So, by mixing and matching the type of loan, the term, and your down payment, you have a lot of control over your monthly electricity costs.

As a rule of thumb:

  • Longer loan term equals lower monthly payments but more money spent on interest
  • Shorter loan term equals higher monthly payments and less money spent on interest

A majority of customers that finance their solar system choose a 12-year loan as it provides a balance of low monthly payments and substantial lifetime savings.

Where to get a solar loan

There are a few ways to find a lender for your solar loan.

Keep in mind, not all lending institutions have the combo and reamortizing loans designed specifically for financing solar systems. So, having an Energy Advisor on your side to shop for loans can be a huge help.

Solar loan qualifications

Like a mortgage or a car loan, you’ll need certain qualifications to be approved for a solar loan.

Loan qualifications vary by lender, but typically you’ll need:

  • A FICO credit score above 650
  • A debt-to-income (DTI) ratio below 50%
  • The primary borrower on the loan must have their name on the title of the home getting solar panels

It’s worth checking to see if you meet these qualifications before going too deep in the solar process. If you need a little boost, adding a co-borrower with a strong credit score and DTI can help you qualify.



Leasing vs Buying Solar Panels

Now that we know the basics of buying solar panels, let’s explore the advantages of buying versus leasing your solar system.

The major difference is who owns the system.

  • If you buy solar panels – either with cash or a loan – you own them
  • If you lease solar panels, someone else owns them

In previous decades, solar leases were more common because buying solar panels was too expensive for most homeowners. However, between the plummeting cost of solar panels and the federal solar tax credit, buying a solar system is much more affordable and accessible.

Advantages of buying solar panels Advantages of leasing solar panels
Greater energy cost savings No maintenance
Increases home value
You claim tax credits and other incentives
Easier to transfer in home sale

Leases are often advertised as “free solar panels” or “zero-down solar.” First of all, there is no such thing as free solar panels. Second, you can just as easily purchase solar panels with a zero-down solar loan.

Like a solar loan, solar leases offer a flat monthly payment to replace your utility electricity bill. However, the major difference is that solar loan payments stay consistent over time, while lease payments increase each year.

Solar leases typically have an escalator that increases your monthly payment by around 3% each year. Over 20 to 25 years, the monthly payments end up being much greater than loan payments, and can even outpace the rate of energy inflation.

The graph below shows how a lease (green line) may be the most attractive option up front, but ends up having the highest overall cost with none of the benefits of owning the system.

The bottom line: Solar leases had their heyday, but today they are considered a last resort for going solar as the savings and benefits of ownership are far greater.

Where to buy solar panels

In most cases, residential solar panels are bought through an installation company, just like kitchen cabinets are typically ordered through a contractor.

In 2023, there were over 800 different models of solar panels available through’s network of installers. By easily comparing quotes from local installers, homeowners have access to a tremendous variety of solar panels, inverters, and batteries.

While it is possible for homeowners to buy solar panels themselves, either used or directly from the manufacturer, there are a few reasons buy them through an installer.

  • Solar installers have relationships with manufacturers that allow them to get better pricing than homeowners
  • Unlike used panels, new solar panels come with 25-year warranties that are crucial to protecting your investment
  • Installers have reliable shipping methods and will deal with shipping and handling issues if they arise

Buying a house with solar panels

The back way into buying solar panels is buying a house that already has solar panels installed.

According to Zillow, homes with solar panels – and other energy efficient features – sell faster and for more money than comparable homes without.

And why wouldn’t solar panels be an attractive feature? You’re essentially buying a house with incredibly low electricity costs and saving money on energy the day you sign the deed.

There are a few things to consider when buying a house with solar panels:

  • Is the system owned or leased? If the home has a leased system, are you prepared to take over the lease payments, or would you rather have the owner pay off the lease and remove the system?
  • Is the roof in good condition? One of the drawbacks of rooftop solar is that the system needs to be removed in order to re-roof the house, which costs money. If the roof seems old, it may be worth negotiating over.
  • Will the system cover your electricity needs? If you will use substantially more electricity than the previous owner (say, by charging an EV at home), then the existing system won’t cover 100% of your consumption. That shouldn’t be a deal-breaker, but it’s worth considering.
  • Will the warranties transfer over? In most cases, the performance and product warranties will transfer in a home sale and continue protecting the system. However, it’s worth establishing that during the sale.

Buying a house with solar panels is getting more common and routine, and is an excellent back door method of buying solar panels.
