When California undercut its personal rooftop photo voltaic market one yr in the past, it surrendered a essential instrument for reaching its bold local weather objectives.
For the final 20 years, California set the nationwide customary for clear power coverage. Governor Arnold Schwarzenegger, a Republican, jumpstarted the rooftop photo voltaic trade in 2006 along with his Million Solar Roofs initiative, and championed binding carbon discount objectives with AB32, which guides the state to this present day. Successor Jerry Brown signed into legislation a deadline to change to a zero-carbon electrical energy system by 2045. Now the state is working to chop the fossil fuels it depends on for practically 40 p.c of its electrical energy, particularly when the nation’s largest photo voltaic fleet goes to sleep for the night time.
Solar kinds the tip of the spear for California’s local weather agenda; it’s the biggest supply of recent power development within the state, simply as it’s for the nation as a entire. Until one yr in the past, California supported each types of photo voltaic improvement: the massive or utility-scale selection, which connects large fields of panels to the utility-run grid, and small or distributed photo voltaic, which clients add to their properties and companies to economize and complement the grid’s clear power provide.
Then, on April 15, 2023, Governor Gavin Newsom’s handpicked utility regulators on the California Public Utilities Commission (CPUC) formally stripped away the net-metering coverage that had helped incentivize the small-scale photo voltaic buildout to this point. They changed it with NEM 3.0, a new coverage that slashed compensation for the solar energy that particular person clients delivered to the grid by upwards of 70 p.c and pegged the a lot diminished rewards for that energy to a novel and inscrutable metric known as the avoided-cost calculator.
The calculator “is so convoluted, the typical buyer and the typical photo voltaic contractor can’t simply determine what the affect could be, whether or not the client’s invoice will go down,” mentioned price design skilled Ahmad Faruqui, a vocal critic of the fee’s choice.
Since then, California’s distributed photo voltaic trade has reported plummeting gross sales and widespread job losses. New gross sales in January had been the bottom for that month since 2014, mentioned Bernadette Del Chiaro, govt director of the California Solar and Storage Association trade group (CALSSA).
In different phrases, California’s local weather governor has overseen a reversal in fortune for the once-favored rooftop photo voltaic trade simply when the state wants all of the clear power it might probably get.
“The long run injury that we’ve sustained now could be what this has accomplished to California’s trajectory for assembly our clear power objectives, assembly our local weather objectives, preserving the lights on as we electrify and preserving prices down,” Del Chiaro mentioned.
Now the rooftop market is in freefall, placing the state susceptible to changing into extra depending on a centralized, utility-driven buildout that’s already plagued with backlogged infrastructure upgrades and ballooning grid prices for purchasers.
Small-scale photo voltaic grew to become a massive local weather answer
It’s true that large-scale photo voltaic has far cheaper unit costs, due to economies of scale. It prices much less to mobilize a work crew and erect photo voltaic panels so far as the attention can see than it does to go rooftop to rooftop. Both sorts of photo voltaic in the end produce an equivalent product: clear electrical energy within the hours when the solar shines.
Monopoly utilities and their allies seized on this truth to counsel that rooftop photo voltaic subsidies are unfair to the rate-paying public: They argued that the entire buyer inhabitants, together with everybody who can’t entry their very own rooftop photo voltaic, was pressured to pay photo voltaic house owners extra for his or her extra manufacturing than it was value to the grid. By railing in opposition to this purported “price shift,” the utilities that cost among the many highest charges within the nation forged themselves as crusaders for the poor households struggling to pay their payments.
The wonky battle over whether or not rooftop photo voltaic forces unfair prices onto these with out it has raged for years. Suffice it to say, operating {an electrical} grid throughout assorted terrain requires the socialization of any variety of prices, which occurs day by day with out protest as long as the outcomes serve some social good. Since the Schwarzenegger period, California policymakers have agreed that tons extra rooftop photo voltaic is a good factor for the state. It would create jobs and assist particular person households management their power prices whereas pushing the entire state towards its local weather objectives.
The numbers bear out that principle. The nationwide Solar Energies Industry Association shared knowledge with Canary Media exhibiting that utility-scale provides as much as 55 p.c of California’s complete 45,605 megawatts of put in photo voltaic capability, as measured by the top of 2023; rooftop, business and group photo voltaic, identified collectively as distributed technology, make up the remaining 45 p.c. All these little rooftops put collectively rival the may of the big photo voltaic fields blanketing the Central Valley and the Mojave.
The tempo of deployment issues tremendously, since California should set up massive numbers of panels yearly for the following 20 years to attain carbon neutrality by 2045. It seems, distributed photo voltaic has a constant monitor document right here, too. Distributed photo voltaic installers constructed extra megawatts than their utility-scale counterparts in three of the final 10 years (2017, 2018, and 2021). In two different years (2019 and 2022), utility-scale eked out a win by lower than a share level. In 2023, large-scale photo voltaic beat distributed photo voltaic by simply 2.5 share factors.
Crucially, photo voltaic is the principle engine of California’s carbon-free power development. New nuclear isn’t taking place, new wind has been largely stalled for years, offshore wind in deep Pacific waters requires navigating a thicket of regulatory and technical hurdles. California’s near-term clear power development is determined by photo voltaic, and lately, distributed photo voltaic has confirmed itself roughly coequal to utility-scale in sheer megawatts positioned into service.
For a ballpark sense of simply how rather more work must be accomplished, a California Air Resources Board research from 2022 notes that the state wants so as to add 72 gigawatts of utility-scale photo voltaic by 2045, and 29 gigawatts of distributed photo voltaic, to hit its clear electrical energy goal. That would entail properly greater than doubling the full present put in small-scale photo voltaic capability.
Newsom’s hand-picked utility regulators didn’t drop a proverbial anvil on a clear power sideshow, however on one in all their two headliners.

When California’s utility regulators voted to finish web metering, they gave the trade simply 4 months discover to organize for the seismic shift, precluding a measured transition. That violated the precept of gradualism that ought to apply when the federal government makes an attempt to restructure a whole trade, Faruqui mentioned.
The outcomes had been each predictable and predicted. As clients retreated from the brand new uncertainty, the photo voltaic trade shed 17,000 jobs, 22 p.c of its California workforce, by the top of 2023, in accordance with estimates from CALSSA late final yr (a brand new survey is at present underway).
“The job losses have been large and extensive ranging,” Del Chiaro informed Canary Media. “There’s barely a firm in California that hasn’t been touched by job layoffs and different price controls.”
The Newsom administration, in distinction, insists the brand new photo voltaic guidelines aren’t a downside. The governor’s press workforce referred Canary Media to California Public Utilities Commission (CPUC) spokesperson Terrie Prosper, who mentioned in an e mail that the brand new coverage is efficient at incentivizing photo voltaic installations.
“California has accomplished extra for the photo voltaic trade than some other state within the nation by offering billions in rebates and incentives since 2006 to drive adoption,” Prosper mentioned. “Now, we’re targeted on modernizing applications and insurance policies to advertise photo voltaic and battery storage, strengthen grid reliability, and curb electrical energy prices for all Californians.”
Prosper cited knowledge that photo voltaic gross sales rose in 2023 in comparison with 2022. This is true: rooftop photo voltaic hit its excessive water mark the yr net-metering died, to the tune of about 2.3 gigawatts per the SEIA knowledge (business photo voltaic added one other 640 megawatts). But 2023 included the three-month scramble when clients raced to purchase their photo voltaic panels earlier than the previous guidelines went away and new, much less profitable ones kicked in. The yr’s document numbers had been pushed by the final gasps of the previous photo voltaic guidelines.
