Guide to Choosing the Best Solar Panel Loan

What Is a Solar Loan and How Do They Work?

A solar loan isn’t a type of loan, but rather a way to use a personal loan. Many personal loan lenders and point-of-sale financing providers offer personal loans that can be used to purchase and install solar panels.

A personal loan provides you with a lump sum of money upfront in exchange for fixed monthly payments over time. You need to apply for a personal loan, and lenders approve you based on your credit score, income, and other factors.

The following table highlights the average cost of installing solar panels in certain cities across the United States.

Where to Get a Solar Loan

You can get a solar loan through your contractor or solar system provider, or you can apply directly for a solar loan from a bank, credit union, or online lender. Financing through your contractor or SunPower will generally offer the lowest APRs and the longest terms.

If you want to choose a contractor that doesn’t offer financing, or if you want to use the loan money for other home improvement needs as well, consider credit unions and online lenders, both of which tend to offer lower rates than banks. 

Comparing Solar Loans

According to Investopedia’s 2023 Personal Loan Borrower survey, funding major home improvements was the second most common reason cited for getting a personal loan, only after debt consolidation. 

When choosing a lender, you’ll want to weigh various pros and cons with each loan. Many borrowers favor loans with the lowest interest rate, which can save you money over time. But there are other factors to keep in mind as you compare loans:

• Availability: Make sure the lender offers loans in your state. 
• Restrictions: Check that the loan can be used for solar panels. 
• Requirements: Narrow down your options to lenders you’re eligible for based on your credit score, income, and debt-to-income ratio. 
• Borrowing costs: Consider the interest rate along with origination fees. Compare the APR, which expresses the annual cost of borrowing as a percentage, across lenders. Pay attention to late payment fees and avoid lenders that charge prepayment penalties. 
• Terms: Some lenders offer longer terms than others. Figure out the shortest term that has a monthly payment you can comfortably afford, and find a lender that offers that term or something close. 
• Co-signers and co-applicants: If you intend to apply with help from a friend or family member who has good credit, narrow down your options to lenders that allow co-signers or co-borrowers. 

How to Qualify for and Apply for a Solar Loan

Lenders typically ask that you meet eligibility criteria before you apply. Here are a few of the most common things that lenders consider from potential borrowers:

• Your age: Lenders cannot discriminate based on age. However, some states require that borrowers meet minimum age requirements before they can enter a legal financial contract with a financial lender.
• Legal residency: Just like age, lenders can't turn you down because of your national origin. They may ask you about your residency status to determine whether you can pay back the loan. Keep in mind that non-residents and non-citizens may still qualify, but it may be tougher to be approved.

To qualify for a personal loan, you’ll need:

• Fair credit: Most personal loan lenders require at least fair credit, while some require good or excellent credit. You’ll need a high credit score to get the lowest advertised rates. The lender will also check your payment history for missed or late payments.
• Sufficient income to cover your debts: Some lenders have minimum annual income requirements. Lenders will also check your existing debts to make sure you’re not overextended. Some may have a maximum debt-to-income ratio, which is the share of your income that you spend making your minimum monthly payments. 

If you think you meet the general requirements, here’s how to apply:

1. Pre-qualify. Get a few rate quotes from lenders that allow you to pre-qualify with a soft credit inquiry. 
2. Choose a loan offer. Choose the loan with the APR and term that best meet your needs. 
3. Formally apply. Accept the loan offer, which will trigger a hard credit check, and submit any additional required documentation.
4. Sign your loan documents. If you’re approved, make sure the final APR offer is acceptable. Review your loan agreement carefully before signing. 
5. Receive the funds. Wait for the money to arrive in your bank account. 

Alternatives to a Solar Loan

You have other ways to potentially finance solar panels if you don’t want to take out a personal loan. They include:

• Rebates and grants: If you meet the income limits, you may qualify for grants or rebates for solar panels from your state, city, or utility company. These can help you save money on your solar installation or cover the cost entirely. Research programs in your area. 
• Solar leasing: Solar leasing has low upfront installation costs, but you’ll pay the company that owns and operates the equipment a monthly fee for a term that typically lasts 20 to 25 years. You won’t own the solar system like you would if you purchased it with a loan. 
• Home equity loan: A home equity loan allows you to borrow against your home equity and receive the funds as a lump sum. The loan is secured by your home and typically repaid in fixed monthly payments over five to 30 years. Home equity loans tend to come with low APRs, but they also require you to pay closing costs. 
• Home equity line of credit: A HELOC is a revolving line of credit, like a credit card, that allows you to tap your home equity up to a limit. You may pay upfront closing costs when opening the line, but then you can make multiple withdrawals during the draw period without reapplying. Most HELOCs have variable interest rates, and monthly payments are often low during the draw period. Like a home equity loan, a HELOC is secured by your home equity, and the lender can foreclose on your home if you default. 

How Solar Panel Tax Credits Work

A tax credit reduces the amount you would otherwise owe in taxes for that year. For solar PV systems installed between 2022 and 2032, you'll receive a federal tax credit equal to 30% of the cost of installing the equipment, after any utility rebates and before state rebates.

For example, if you paid $24,000 for your system in 2023, you would owe $7,200 less in taxes for 2023. If you only owed $5,000 in taxes for 2023, you could carry over the remainder of the tax credit to 2024. 

Other tax incentives may be available from your state or city, including sales tax exemptions. Rebates and grants may also be available from your city, state, or utility company.
