The Marketplace Median, and What Moves It
EnergySage’s marketplace puts the median quoted solar loan rate at 7.5%, with a median loan term of 25 years. That median is not the rate any individual homeowner should expect, it moves with the borrower’s credit score, the specific lender, whether the loan is secured against the home or unsecured, and the term chosen, so the actual quote a homeowner receives can sit well above or below it.
Why the Advertised Rate Alone Can Mislead
Solar loans frequently bury an origination or dealer fee inside a lower advertised interest rate, meaning a loan quoted at a lower headline rate can still work out more expensive once that fee is priced in than a loan with a higher stated rate and no fee attached. That mechanic connects directly to a number already well documented on this site: the average solar loan dealer fee runs roughly 22% in 2026, adding more than $5,700 to a typical loan balance. APR, which factors in both the rate and any embedded fees, is the only number that lets a homeowner or a sales team compare two loan offers on equal footing. The advertised rate by itself does not.
Which Lenders Show Up Most in 2026 Quotes
Credit Human, Climate First Bank, Dividend Solar, Atmos Financial, and EnFin Financing appeared most often in installer-generated loan quotes on EnergySage’s platform as of 2025, a named lender roster broader than the three brands most commonly referenced in general solar-financing coverage. Knowing which lenders actually show up in current quotes is a more useful starting point for a rate conversation than assuming any single named brand dominates the market.
The Numbers
The median quoted solar loan rate on EnergySage’s marketplace is 7.5%, with a median loan term of 25 years.
Actual solar loan rate depends on the borrower’s credit score, the specific lender, whether the loan is secured or unsecured, and the chosen term.
A lower advertised solar loan rate can still be more expensive overall once an embedded origination or dealer fee is counted, which is why APR is the only apples-to-apples comparison number.
The average embedded solar loan dealer fee runs roughly 22% in 2026, adding more than $5,700 to a typical loan balance, the mechanism most likely to distort an advertised rate.
Credit Human, Climate First Bank, Dividend Solar, Atmos Financial, and EnFin Financing were the lenders most frequently quoted on EnergySage’s platform as of 2025.
