California, once a pioneer in fostering the US solar industry, is now facing a significant slowdown in rooftop panel sales, posing a threat to widespread adoption.
Job cuts among installers and a surge in bankruptcies are becoming more prevalent.
Even established companies like Enphase Energy Inc., a key player in the sector, have announced a 10% workforce reduction and the closure of two contract factories, attributing the decision to California’s challenges in a letter from CEO Badri Kothandaraman to the staff.
This downturn is a result of recent regulatory changes in California that reduced the earnings for solar homeowners selling excess electricity to the grid.
Compounding the issue, higher interest rates have made solar systems more expensive.
According to research firm Ohm Analytics, which monitors the solar market, private residential installers in the state have seen sales plummet by 67% to 85% since the regulatory change took effect in April.
The decline in sales, particularly in a state that leads in US solar installations, poses a setback for a crucial source of green energy just as President Joe Biden aims to expedite the country’s shift toward clean energy.
California is not the only state facing this issue; more than a dozen others have reduced their subsidies, citing concerns that they contribute to higher utility rates for homeowners unable to afford solar systems.
Consequently, the rapid nationwide growth of rooftop solar in recent years is likely to decelerate.
Residential solar installations in the US experienced an average annual increase of 32% from 2019 to 2022, as reported by BloombergNEF. However, the research firm now anticipates a 5% annual growth rate for the remainder of the decade.
“I’m very concerned about whether or not we’ll make it through winter,” said Ross Williams, CEO of the San Diego-based installer HES Solar.
His sales have plummeted to about 20% of 2022 levels, and he’s laid off more than half of his 75-person staff. “It’s been pretty dramatic for us going through this process.”
