Credit requirements for solar loans vary more than people expect, and a lower score doesn't always mean no options.
There's no single universal credit requirement
Different lenders set different minimum credit score thresholds for solar loans — some programs have served a fairly broad range of credit profiles, while others require stronger credit for the best rates. There's no substitute for checking current requirements with specific lenders rather than assuming a fixed industry-wide number.
Credit score affects APR more than eligibility, for many lenders
Even among borrowers who qualify, a higher credit score typically unlocks a lower APR — see the loan APR calculator for how even a modest rate difference compounds into meaningfully different total interest over a loan term.
Options beyond a traditional solar loan
- Home equity loan or HELOC — sometimes offers more favorable terms if you have home equity, though it puts your home more directly at stake as collateral.
- Lease or PPA — some programs have more flexible credit requirements than a purchase loan since you're not financing equipment ownership; see our lease vs buy comparison for the trade-offs.
- Cash purchase — sidesteps credit requirements entirely if it's financially feasible, though it requires the full upfront capital.
A co-signer or joint applicant can help
Some lenders allow a co-signer with stronger credit to help a primary applicant qualify or get a better rate — worth asking about directly if your own credit profile is a limiting factor.
Frequently asked questions
Can I get solar financing with fair or below-average credit?
Some programs have historically served a broad credit range, though terms (APR, down payment) are typically less favorable than for strong credit — check with multiple specific lenders rather than assuming based on a general credit tier.
Does applying for solar financing affect my credit score?
Initial pre-qualification checks are often a soft pull that doesn't affect your score, while a full application typically involves a hard pull that can have a small, temporary impact — confirm which type of check a specific lender uses before applying broadly.
