Does a Solar Loan Affect Your Credit Score?
July 1, 2025

Quick Answers
Applying for a solar loan typically involves a hard credit inquiry from the lender, which can cause a temporary, minor dip in your credit score.
Once approved, the new loan is added to your credit report, which can initially impact factors like your credit mix and the average age of your accounts.
Making consistent, on-time payments on your solar loan demonstrates creditworthiness and will positively build your payment history, strengthening your credit score over time.
What Is a Solar Loan?
A solar loan is a financial product that allows homeowners to purchase a solar energy system for their property. Unlike a lease or power purchase agreement (PPA), this type of financing results in direct ownership of the panels upon installation or loan maturity. This means you can claim any available tax credits and incentives directly, rather than them going to a third-party company.
Similar to other significant financing, such as a mortgage or auto loan, lenders will review your credit score to determine your eligibility and interest rate. A stronger credit history typically qualifies you for more favorable terms, which can lower the overall cost of your system. Consistently making on-time payments for your solar loan can also contribute positively to your credit history over the life of the loan.
How a Solar Loan May Impact Your Credit Score
Like any significant financing, a solar loan can influence your credit score. Understanding the process helps you navigate the temporary dips and leverage the long-term benefits for your financial health.
- The Hard Inquiry: When you apply, lenders perform a hard credit inquiry to review your financial history. This can cause a minor, temporary dip in your score, which is standard for most loan applications.
- New Account and Debt Load: Upon approval, the loan appears as a new account on your credit report. This increases your overall debt and can initially lower your score slightly by affecting your credit utilization ratio.
- Building Payment History: Consistently making on-time payments is crucial. A positive payment history is the most heavily weighted factor in your credit score, helping it to recover and improve over time.
- Diversifying Your Credit Mix: A solar loan adds an installment loan to your credit profile. Having a mix of credit types, such as revolving credit and installment loans, is generally viewed as a positive for your score.
- Long-Term Impact: Over the life of the loan, successfully managing the debt demonstrates creditworthiness. Paying it off completely leaves a positive history on your report, which can benefit your score long-term.
How Much Will a Solar Loan Affect Your Credit Score?
A solar loan can impact your credit score in several ways, both initially and over the long term. Here are the key factors to consider when financing your solar panel system.
- Hard Inquiry. When you apply for a solar loan, lenders perform a hard credit check. This can cause a small, temporary dip in your credit score for a few months.
- New Debt Account. A new loan increases your total debt and can lower the average age of your accounts. These factors might temporarily lower your score until you establish a payment history.
- Payment History. Consistently making on-time payments is crucial for building good credit. A strong payment history on your solar loan will positively impact your score over the loan's life.
How You Can Avoid a Solar Loan Affecting Your Credit Score
Pay with Cash
The most straightforward way to prevent any impact on your credit is to pay for the solar system with cash. This approach completely bypasses the need for a loan, eliminating credit checks and new debt, thus leaving your credit score entirely unaffected by the purchase.
Use Home Equity
Another option is leveraging your home's value through a home equity loan or a Home Equity Line of Credit (HELOC). While this is still a form of debt, it is secured by your property, which can sometimes result in more favorable terms than a dedicated solar loan.
Explore a Lease or PPA
With a solar lease or a Power Purchase Agreement (PPA), you don't own the panels. Instead, you pay a monthly rate to use the energy they produce. These arrangements often have less stringent credit requirements and don't typically appear as installment debt on your credit report.
Ways to Improve Your Credit Score
Your credit score plays a crucial role in your financial life, but it's not set in stone. Whether you're aiming to boost your FICO® score or VantageScore, there are proven methods to improve your creditworthiness over time.
- Monitor your credit reports. Regularly check your reports from all three major bureaus to spot and dispute inaccuracies, which also helps you track progress and detect identity theft.
- Automate your bill payments. Since payment history is the most significant factor in your score, setting up automatic payments ensures you never miss a due date.
- Lower your credit utilization ratio. Aim to use less than 30% of your available credit by paying down balances or requesting a credit limit increase.
- Become an authorized user. Being added to the credit card of someone with a strong payment history can help you build your own credit file.
- Diversify your credit mix. Lenders like to see that you can responsibly manage different types of credit, such as credit cards and installment loans.
- Limit hard inquiries. Applying for too much new credit at once can temporarily lower your score, so be sure to space out your applications.
The Bottom Line
A solar loan will likely cause a temporary dip in your credit score due to the initial hard inquiry. However, consistent, on-time payments can help improve your credit history over the long term.
