With more than 2 million people who have already made a switch to solar, it is no doubt proof that going solar is an investment worth the while.

Solar financing is a means to assist homeowners intending to go solar with loan and lease programs that would help them come up with the funds required to buy and set up a solar system which includes panels, inverters, batteries and installation equipment.

This post is aimed at looking through the different solar financing options and how they work and operate.

Solar Financing

How Does Solar Financing Work

Solar financing is an option for individuals to own solar panels and its equipment by paying in cash, taking a loan or leasing it. These are the channels deployed to come up with the funds needed to purchase a solar system. 

You can choose to pay in installments over time instead of out-of-pocket upfront at the time of purchase. Or either take a loan and pay the amount and accumulated interest monthly. The amount you will pay monthly is estimated or calculated based on the interest and other factors like your income, credit, lender’s rate, existing debts and so on.

There are a number of financing partners available through EnergySage, Greenage Technologies Power Systems Limited and other platforms and works fine for so many people. If you don’t have the funds handy, it is best you contact solar companies like Greenage, your credit union, bank and solar installers.

The Interest rates of these companies on solar loans range from about 5% to 36%. Banks and credit unions can also help you purchase solar panels.

3 Solar Financing Options

Financing your solar switch is dependent on your readily available income, income taxes, your location, and your credit score.

There are 3 main types of solar financing options. They are:

  1. Cash purchase option
  2. Solar loan option
  3. Solar lease/Power purchase agreement option.

1. Cash purchase option

The cash purchase option is the best option for homeowners looking to maximize their solar savings. 

Purchasing a solar system is a significant purchase with a heavy investment capital required and if you already have enough cash to do this then you’re taking the best solar financing option.

How is it the best?

When you buy a residential solar system upfront, you have automatically bought 100% of your electrical needs for the next 25years in advance.

What this means is that you will not have to worry about the subsequent hikes in electricity bills.

This financing option also qualifies you for tax incentives associated with going solar. A good example is the Federal Tax Credits and Rebates.

2. Solar loan option

The emergence of solar loans has made solar financing easier, especially for homeowners who can not make an upfront purchase at once.

With the solar loan option, you have the opportunity to go solar with little or no money down. But, if you decide to finance your solar through the solar loan option then you would need to pay extra attention to some key things like;

  • The annual percentage rate
  • Origination fee
  • Loan terms
  • Interest fees and rate 
  • And the overall payment period.

Two types of Solar Loan

There are 2 main types of loans. They are;

  • Secured solar loan
  • Unsecured solar loan.

Secured solar loan

A secured solar loan would require the borrower to present collateral to the lender. This collateral acts as a form of security for the lender and as such would attract a lower interest rate for the borrower.

Unsecured solar loan

The unsecured solar loan type does not require any form of collateral and puts the lender at a higher risk.

This in turn attracts a higher interest rate on the borrower.

3. Solar lease/ Power purchase agreement (PPA)

A solar lease involves you paying a fixed amount of money periodically ( say monthly ) to a solar company for using their panels and other related pieces of equipment that would be installed on the roof.

While in a power purchase agreement, you pay for the electricity being produced by the solar system i.e you pay for the exact amount of electricity you consume.

A solar lease would at first look very attractive especially since you will not need any money down to make an initial down deposit but, leasing a solar system will not qualify you to receive any incentives associated with using solar energy as all incentives would be giving to the solar company leasing you the panels.

These lease payments might also include a percentage with which there would be a yearly increase in the amount of money you pay monthly. This inclusion is known as an escalator.

The periodic payments in your solar lease program do not consider how much energy you must have consumed as payment amounts are always fixed. As such you might end up paying for more than you consumed.

The pros and cons of the different solar Financing options

Making the switch to solar energy can be quite expensive, this is why it is essential to properly look into the different solar financing options. 

This would help you identify which one you’re more suited for.

1. Cash purchase

Cash purchase stands as the best solar financing option because it provides the largest long-term value.


✓ You do not have to pay any interest rates

✓  You can begin to save on your monthly electric bills immediately

✓ It increases the value of your home

✓ It makes you eligible for solar incentives


✓ You are solely responsible for the maintenance of your solar panels.

✓ It requires a large upfront capital

2. Solar loans

Solar allows you direct ownership of the solar system without having to make any down payments as well as helps you spread the payment for the solar system over a period of time letting you pay back in bits.


✓ It requires little or no cash as upfront payment

✓ It allows you to make other investments elsewhere whilst investing in solar energy

✓ Solar loans still make you eligible for solar incentives

✓ Helps to increase your home value


There’s an interest rate on every payment which would make you end up paying more than the actual worth of the solar system.

3. Solar lease/ PPA

This solar financing option helps you use clean renewable energy sources without owning the solar system.


✓ It requires zero down payment

✓ Requires zero maintenance

✓ Makes room for low-income families to support clean energy


✓ Brings zero increase to the value of your home

✓ Does not help in maximizing your return on investment

✓ It does not qualify you for any solar incentives
