Rising borrowing costs are hitting solar stocks harder than almost anything else in the market Thursday, and the reasons behind the selloff reveal deeper vulnerabilities across the entire renewable energy sector.

Solar stocks are sliding sharply Thursday as elevated borrowing costs add pressure to an industry that depends heavily on project financing. First Solar (NASDAQ:FSLR | FSLR Price Prediction) stock is down 8% to $177.45, while SolarEdge Technologies (NASDAQ:SEDG) stock is falling 5% to $31.76 and Enphase Energy (NASDAQ:ENPH) stock is down 3% to $32.04.
The selling is broad across the solar industry, with Invesco Solar ETF (NYSE ARCA:TAN) down 4% to $43.23 while SPDR S&P 500 ETF Trust (NYSE ARCA:SPY) is down 0.54% to $763.69. Higher interest rates can make new solar installations and upgrades more difficult to finance, potentially slowing private investment even when demand for renewable power remains intact.
Solar projects often require substantial upfront capital before generating revenue or reducing energy costs, making financing conditions particularly important for First Solar, SolarEdge and Enphase Energy. Higher borrowing costs can raise the required return on new projects and make some planned installations less attractive to developers, businesses and homeowners.
First Solar stock is facing the steepest decline among the three major solar names Thursday, although the immediate catalyst remains unclear. The broader weakness in First Solar stock, SolarEdge stock and Enphase Energy stock suggests that investors are also responding to macroeconomic concerns rather than a single company-specific development.
The financing pressure can affect different parts of the solar industry in different ways. First Solar supplies utility-scale solar modules, while SolarEdge and Enphase Energy provide technologies used in solar installations, meaning higher financing costs can ultimately affect equipment demand if developers delay projects or customers reduce spending.
First Solar has benefited from U.S. manufacturing incentives and demand for domestically produced solar modules, but First Solar stock can still be sensitive to changes in clean-energy policy and project economics. First Solar’s large utility-scale exposure also means financing conditions can influence the timing of projects even when the long-term demand outlook remains constructive.
Another issue surrounding First Solar is the company’s decision to withdraw its Section 337 complaint involving certain TOPCon solar manufacturers. The move has generated discussion among traders about competitive conditions in the solar-module market, although the immediate relationship between the legal development and Thursday’s First Solar stock decline isn’t clear.
First Solar’s position as a major U.S. solar manufacturer gives First Solar a different business profile from SolarEdge and Enphase Energy. That distinction could matter as investors weigh the effects of financing costs, U.S. clean-energy incentives, module pricing and project demand across the solar industry.
SolarEdge stock is down 5% to $31.76 as the broader solar selloff continues. SolarEdge has faced a difficult operating environment as residential solar demand, inventory levels and financing conditions have pressured the solar equipment market.
Enphase Energy stock is also under pressure, falling 3% to $32.04 despite Enphase Energy’s focus on microinverters, batteries and energy-management systems. Higher financing costs could make residential and commercial solar-plus-storage installations less attractive at the margin, particularly when customers are already weighing higher equipment and borrowing costs.
The weakness in SolarEdge stock and Enphase Energy stock also highlights the difference between equipment suppliers and utility-scale manufacturers. SolarEdge and Enphase Energy can be affected by installation volumes and customer financing conditions, while First Solar can be more directly exposed to the economics and timing of large utility-scale projects.
U.S. clean-energy policy remains another source of uncertainty for First Solar, SolarEdge and Enphase Energy. Changes to tax credits and other incentives could alter project economics, while uncertainty can cause developers and customers to delay investment decisions as they assess the financial benefits of new solar installations.
The 4% decline in the Invesco Solar ETF puts Thursday’s weakness into broader industry context, while the smaller 0.54% decline in the SPDR S&P 500 ETF Trust suggests solar stocks are experiencing substantially more pressure than the wider market. Investors can watch for signs that higher borrowing costs are slowing project commitments, while First Solar stock, SolarEdge stock and Enphase Energy stock could also respond to changes in policy, demand and financing conditions.
The combination of elevated interest rates, policy uncertainty and company-specific concerns leaves the solar sector with several factors to balance. Investors should consider keeping their position sizes modest as First Solar stock, SolarEdge stock and Enphase Energy stock remain sensitive to financing conditions and shifts in expectations for renewable-energy investment.
