In a profound policy shift, the California Public Utilities Commission made a decision in late 2022 to reduce the rate that utilities pay homeowners with new solar panels by about 75% for selling surplus power to the grid. The new rate structure came into effect in April 2023, causing a significant decline in consumer demand for residential solar installations. This decline not only threatens the state's efforts to combat climate change but also jeopardizes Governor Gavin Newsom's vision of making clean energy affordable to disadvantaged communities.

The immediate impact of the rate changes has been felt by the solar industry, with solar companies being pushed to the edge of closure. According to industry estimates, as many as 17,000 solar workers in California may have lost their jobs by the end of 2023. The decline in residential solar applications has been staggering, with a 90% drop in May 2023 compared to the previous year. From May to November 2023, there were about 82% fewer applications for solar connections.

The decision to reduce reimbursement rates has raised concerns about how California will meet its climate change goals without a thriving residential solar market. Solar power is essential to achieving California's ambitious targets of 90% carbon-free electricity by 2035 and 100% by 2045. It is projected that large-scale and rooftop solar will provide over half of the state's grid power by 2045.

Deepak Rajagopal, an energy economist at UCLA's Institute of Environment and Sustainability, stated that the decline in demand for rooftop solar was to be expected after the "generous" reimbursement system was changed. He believes that the demand for rooftop solar may slow down in the short term and increase again over time, but the overall effect remains uncertain.

The reduction in reimbursement rates has had a particularly significant impact on low- and middle-income homeowners who were starting to adopt solar systems to lower their utility bills. As costs for solar installations have come down, more homeowners of modest means have been able to afford solar systems. However, with the new rates, it may take them 10 years or more to recoup their investment, compared to the previous 6 to 8 years.

The job losses within the solar industry are also cause for concern, particularly for communities where clean energy jobs serve as a pathway to economic stability, especially for women and people of color. Solar industry executives argue that the rate changes disproportionately affect low-income households that can't afford solar panels and undercut the progress made in bringing clean energy to underserved communities.

While the utilities commission defended the rate changes as a means of ensuring fairness and shifting to a more sustainable model, critics argue that the policy negatively impacts the growth and accessibility of solar energy. The new rates only apply to new solar installations for customers of Pacific Gas & Electric, Southern California Edison, and San Diego Gas & Electric. Additionally, the commission plans to expand the lower payment rates to commercial businesses and multifamily dwellings that install solar panels.

The fate of California's residential solar market remains uncertain, and both utilities and solar companies are left waiting to see if the decline in demand is temporary or permanent. Many industry experts and stakeholders have expressed the need for a reevaluation of the state's solar policies, emphasizing the importance of finding a balance between affordability, sustainability, and equity in the transition to clean energy.

As California grapples with the implications of the decision to slash solar reimbursement rates, the future of the state's clean energy landscape hangs in the balance. The pressure is on policymakers to reassess and calibrate their approach to ensure a sustainable and equitable transition to a carbon-free future.
