Amid a shifting landscape for green energy policy, the US residential solar sector is bracing for a prolonged downturn that could last a decade. According to reports from Bloomberg New Energy Finance (BNEF), residential solar installations are not expected to recover to the record levels seen in 2023 within the next ten years. This slump is primarily driven by the sunsetting of a key federal tax credit and elevated interest rates, which have severely damaged the underlying economics of rooftop solar projects.

Sign InThe pessimistic outlook is compounded by high borrowing costs that have deterred homeowners, with the MBA 30-year mortgage rate standing at 6.6% per market data on June 10, 2026. Peer companies such as SunPower and Enphase Energy are facing significant margin pressure as payback periods for solar investments lengthen. This trend is exacerbated by US annual inflation reaching 4.2% in June, which continues to strain consumer budgets for high-cost home improvements compared to previous fiscal cycles.
In the equity markets, ENPH closed at $52.40 and RUN at $12.47 as of June 15, 2026, while SPWR remained at a distressed level of $0.7811. Traders should closely monitor upcoming housing market data, as any further weakness in residential activity could act as a negative catalyst for solar demand. The combination of high financing costs and reduced incentives remains the primary hurdle for a sector recovery in the near term.
