What changes your rate / answer
- Credit Profile: A higher business credit score generally unlocks lower APRs, reducing the total cost of capital. Even small improvements in credit can significantly impact your interest savings over a 60-month term.
- Loan Term: Shorter terms increase monthly payments but decrease the total interest paid over the life of the loan. Balance this against your current monthly revenue predictability.
- Collateral: Utilizing the equipment you are purchasing as collateral can sometimes secure better rates compared to unsecured working capital for solar installers, which often carry higher interest rates due to the lack of physical security.
- Down Payment: Increasing your upfront contribution reduces the principal amount financed, directly lowering your monthly obligation and potential interest charges.
How to use this
- Loan Principal: Input the total cost of the solar hardware, including any relevant tax, shipping, and installation fees. Do not include future maintenance costs in this initial figure.
- Interest Rate: Adjust this based on current market trends. If you are unsure, start with 9–12% for a realistic view of current rates for established contractors.
- Loan Term: Select a timeline that aligns with the expected revenue generation of the new equipment. Consult our apply page to see standard term limits for different asset types, including racking, inverters, and heavy machinery.
- Interpreting Results: Use the output to stress-test your monthly cash flow. If the number exceeds your buffer for quiet sales months, consider adjusting the term or increasing your down payment. By adjusting these variables, you can simulate how different lending products impact your bottom line. We recommend testing your scenarios against at least two different interest rate brackets to ensure your project remains profitable even if market costs shift slightly.
