A fight over the future of California’s rooftop solar industry is intensifying, as state officials contemplate comprehensive reforms to a program that pays homeowners for clean power they share with the electric grid.


Lawmakers and utility company regulators are weighing whether to sharply reduce bill credits that residents with solar panels attached to their homes receive in exchange for excess energy they generate. Officials are also considering imposing a new monthly charge on them, as well as other changes to the program known as net energy metering.

The proposals’ supporters say residents who have solar panels are being overpaid for their excess energy, allowing them to avoid electric grid costs that run into the billions of dollars statewide. They contend that forces everyone else, including people with fewer means, to foot the bill.

But opponents say many of the policy changes would be little more than a profit grab by investor-owned power companies that could devastate the rooftop solar industry, hampering efforts to decentralize the grid and make it more resistant to wildfire risk and blackouts.


The debate is playing out on multiple fronts. The most immediate is AB1139, which needs to pass out of a key fiscal Assembly committee by Friday to advance through the Legislature. Critics of the bill say its provisions, which include new charges and lower credits for power shared with the grid, could ruin California’s rooftop solar market.

“Under no uncertain terms, AB1139 kills rooftop solar,” said Bernadette Del Chiaro, executive director of the California Solar & Storage Association. “It moves us to a time at which only the extremely wealthy can afford to go solar. It moves us back in every possible way: climate change, equity, grid reliability, wildfire abatement.”

Assembly Member Lorena Gonzalez, D-San Diego, who is carrying the bill, said the idea that she’s trying to destroy the rooftop solar market is “ridiculous” and “a silly argument.” In her mind, AB1139 tries to right-size an unfair burden faced by those who don’t have solar panels.

Gonzalez said she has solar panels on her home and believes the current net metering program pays her too much. She said her most recent electric bill was negative, meaning she owed no money and doesn’t have to pay fixed costs for the electric system that her neighbors without solar can’t escape.

“I actually hope we continue to grow rooftop solar,” Gonzalez said. “We just have to be realistic with people about the actual cost.”

Established in 1995 and modified in 2016, net metering has been a huge factor fueling the growth of California’s rooftop solar industry — more than 1 million homes across the state have panels. Under the program, solar customers are compensated at the retail price of electricity for the extra energy their panels send to the rest of the power system. But they still have to pay certain charges that support public programs, such as low-income bill assistance, and they’re charged a one-time fee — usually $75 to $145, depending on the utility — to connect their panels to the grid.

Independent of AB1139, regulators at the California Public Utilities Commission are already considering changes to net metering. Pacific Gas and Electric Co. and Southern California’s large investor-owned electric companies submitted a proposal in March that would accomplish some of the same goals as the bill. A proposed decision should be ready for commissioners to consider by December, with a vote likely early next year.

Gonzalez said her bill’s changes to net metering would not take effect if the commission adopts its changes by February and they’re implemented by the end of 2023.

Still, some solar supporters worry that the bill’s passage could motivate regulators to adopt far-reaching changes, including monthly charges of about $70 that utilities have proposed for new solar customers. Dave Rosenfeld, executive director of the Solar Rights Alliance, said he viewed the bill as “instructions to the CPUC on what to do.”

Rosenfeld was particularly alarmed by a proposal in AB1139 to switch existing rooftop solar customers to the newer, less favorable net metering system 10 years after their panels were installed. He said that could create marketplace chaos as the state’s current policy guarantees residents’ solar investments for 20 years, the standard lifetime of rooftop panels.

“Nobody’s going to trust this stuff,” Rosenfeld said.

Moreover, Rosenfeld thinks rooftop solar panels are being misconstrued as a major reason for California’s steep electricity prices, when other factors like utility profit motives are far more to blame.

“The premise of this bill is based on a lie,” he said.

Off-Grid Living Systems

Water | Power | Waste Water Treatment | Heating/Cooling

The systems of a building. These are the systems that go into the structural shell of the building for occupancy. Some or all of these systems can be used instead of the conventional methods to provide utilities to buildings. This can make the build more sustainable, secure and healthy than only using conventional utilities.

All systems can have automated conventional backups. All systems can be added to existing conventional buildings as a renovation project.

Living with sustainable off-grid systems enhances our lives, secures our lives and is a better investment than conventional buildings.

This increases both psychological and physiological comfort.
