The latest readings stay below early-2026 peaks, but they continue to run above historical levels in the near term.

- Year-over-year, annualized net losses climbed 121 basis points and late-stage delinquencies increased 30 basis points, while early-stage delinquencies improved by 4 basis points.

September index performance trends
As reported by KBRA, citing Kroll Bond Rating Agency, annualized net losses in its Solar Loan ABS Index increase 25 basis points month over month to 4.20%. Early-stage delinquencies, defined as loans 30 to 59 days past due, edge down 1 basis point to 0.92%, while late-stage delinquencies, covering loans 60 days or more past due, rise 6 basis points to 1.75%.The increase in late-stage delinquencies marks the second straight monthly gain after five months of improvement. The combination suggests that while some near-term payment stress eases slightly, more severe borrower distress remains a pressure point for the sector.
Market implications for U.S. solar ABS
On a year-over-year basis, annualized net losses remain significantly elevated, up 121 basis points, and late-stage delinquencies rise 30 basis points.

Our earlier article on how higher interest rates are reshaping private equity and credit markets explained that investors are placing more emphasis on cash flow, pricing discipline, and operational improvements as the credit cycle shows early signs of strain. We noted that higher-for-longer rates are creating opportunities in stressed capital structures and complex restructurings, particularly for experienced distressed-debt investors with patient capital.
