Bad credit narrows your solar options but doesn't close them off. The simple version: solar loans usually want a FICO score of 640 to 660 or higher, leases and Power Purchase Agreements typically accept scores in the low 600s, and below that you're looking at PACE financing (no credit check, secured against your home) or community solar (a no-install subscription option in roughly 20 states). Each path has real trade-offs, and the right one depends on your specific score, whether you own the home, and whether you can wait six months to improve your credit before applying.
What your score actually means for solar financing
Solar lenders treat credit scores in tiers, and your tier determines both whether you qualify and what you pay. Roughly:
- 740 and above: excellent. You'll see the lowest APRs (often 6–8%), full loan amounts, and your pick of lenders.
- 680–739: good. Most major solar lenders approve at competitive rates (typically 7–10%).
- 640–679: fair. You can still qualify for most solar loans, but APRs run higher (10–14%), and some lenders may require a co-signer or larger down payment.
- 600–639: limited. Traditional solar loans become hard to get. Specialized lenders may approve at high APRs (12–16%), and leases or PPAs become the more realistic path.
- Below 600: loans unlikely. Lease/PPA, PACE financing, or community solar are typically the only options.
The reason the threshold lands around 640–660 is that solar loans are unsecured, long-term, and large (typical loan amount $15,000–$30,000 over 10–25 years). Lenders price that risk heavily on credit history. The rate you get is roughly the difference between solar being a financial win and an expensive break-even.
The lease and PPA trade-off (read this before signing)
Leases and Power Purchase Agreements are pitched aggressively to homeowners with credit challenges because they have lower qualification thresholds. They're also pitched because they're the most profitable financing structure for the installer. Both things can be true at once. The honest version of the trade-off:
With a lease or PPA, you don't own the system. The leasing company owns it and you pay them monthly. They claim the 30% federal Investment Tax Credit (consult a qualified tax advisor about how the credit interacts with your specific tax situation), not you. Lease and PPA payments typically escalate 1–3% per year, so a payment that starts at $120/month can be $160 or more by year 20. You don't get the resale premium that owned solar adds to home value. When you sell the home, the buyer has to qualify to assume the lease or you have to buy it out, which can run $20,000+ depending on years remaining.
None of that makes leases evil. For someone who genuinely can't qualify for a loan, can't use the tax credit (no federal tax liability), or doesn't have the cash, a lease or PPA can still produce some monthly savings versus the utility. But it's the lowest-value way to do solar. If a six-month focus on improving your credit could move you from a 620 to a 680 and qualify you for a loan, that's almost always the better path.
PACE financing: an underused option
PACE (Property Assessed Clean Energy) is a state-level financing structure where the cost of a solar system is repaid through an additional assessment on your property tax bill, typically over 10–20 years. Approval is based on home equity and property value, not your credit score, which makes it accessible for homeowners with bad credit who own their home.
PACE is currently available for residential solar in California, Florida, and Missouri (with more states adding programs over time). The advantages are real: no credit check, no upfront cost, you own the system (so you get the federal tax credit), and the assessment transfers with the property if you sell.
The disadvantages are also real. The PACE lien is attached to the property, which can complicate selling or refinancing the home. Some mortgage lenders (Fannie Mae and Freddie Mac in particular) have at various times restricted or refused loans on PACE-encumbered properties, so check whether your future refinancing plans are compatible before signing. PACE assessments also tend to carry interest rates higher than traditional solar loans, often 6–9%.
For homeowners with bad credit and meaningful home equity, PACE can be the right answer. For homeowners planning to sell or refinance in the next few years, it usually isn't.
Community solar (if you can't install at all)
If credit is a real barrier and you don't want the complications of a lease or PACE, community solar is worth knowing about. It's a subscription model where you pay for a share of a local solar farm and receive credits on your utility bill in exchange. There's no install on your roof, no credit check in most programs, and no long-term commitment in many cases.
Community solar is available in roughly 20 states with active markets, including New York, Massachusetts, Minnesota, Illinois, Colorado, New Jersey, and Maryland. Savings are usually modest (5–15% off your electricity bill), but the financial commitment is minimal and the qualification barrier is essentially zero. If your state has it and you can't qualify for a loan, this is often a better option than a lease.
The case for waiting six months
The most common mistake we see is homeowners with mid-600s credit signing leases when six months of credit improvement would have qualified them for loans. Going from 620 to 680 is achievable for most people in six to twelve months with three focused moves: pay down credit card balances below 30% of your limits, dispute any errors on your credit report, and don't apply for new credit during the prep period.
The financial difference is large. A 25-year solar lease versus a 15-year solar loan on the same $20,000 system can be a $25,000–$40,000 lifetime savings difference, depending on rate escalation. The federal tax credit alone is worth roughly $6,000 on a typical system, and you only capture that with ownership. Six months of credit work is almost always worth the wait.
The exception is if a credit-improvement timeline doesn't apply: bankruptcy still on your record, foreclosure history, or a credit score that's already as high as it can realistically go. In those cases, lease/PPA/PACE/community solar is the right answer, not waiting.
What to do next
Start with your actual credit score. Pull your free reports from AnnualCreditReport.com and check your FICO score through your bank or a free service. Knowing where you sit is the first step.
Then estimate what a system would actually cost and save on your roof, so you know what financing terms you're shopping for. Our solar calculator gives you a system size and savings estimate based on your address. When you're ready, compare quotes from pre-screened local installers who can walk through the financing options realistic for your specific credit profile.
Frequently asked questions
What credit score do I need for a solar loan?
Most solar lenders look for a FICO score of 640 to 660 or higher to approve a loan, with the best APRs reserved for scores above 700. Scores in the 600–640 range can still qualify, but expect higher interest rates and possibly a co-signer requirement. Below 600, traditional solar loans become difficult and lease/PPA financing is usually the realistic alternative.
Can I get solar with a 580 credit score?
It is difficult through traditional loans. Most solar lenders draw the line around 600–640. With a 580 FICO, you can usually still qualify for a solar lease or Power Purchase Agreement, which underwrite based on payment history rather than credit score, but you give up the federal tax credit and the long-term savings ownership provides. PACE financing and community solar are other no-credit-check options.
Do solar leases check credit?
Yes, but their thresholds are lower. Most solar lease and PPA providers approve customers with FICO scores in the low 600s, and some specialized programs accept scores as low as 580. The trade-off is that you don't own the system, you don't receive the 30% federal tax credit, and your monthly payment usually escalates 1–3% per year for the life of the contract.
What is PACE financing for solar?
PACE (Property Assessed Clean Energy) is financing repaid through an assessment added to your property tax bill rather than a traditional loan. Approval is based on home equity and property value rather than a credit check, which makes it accessible for homeowners with poor credit. The trade-off is that the PACE lien is attached to the property, which can complicate selling or refinancing the home.
How can I improve my credit score before applying for a solar loan?
The fastest moves are paying down credit card balances to below 30% of your limits, disputing any errors on your credit report, and making every payment on time for six to twelve months. Hard credit inquiries (multiple loan applications) hurt scores temporarily, so wait until you're ready to apply before shopping. Going from a 620 to a 680 score often shifts you into significantly better solar loan terms.
