The Brief

On a sunny, early summer morning, Matthew Milner waited in his driveway in the Berkeley hills. It was his solar install day, and he was excited. He greeted the installers and walked them around to the back of his house. But instead of pointing to his roof, he pointed to his wooden backyard fence. That is where these solar panels would go, tilted, with their bottom edge on the ground, and top leaning against the fence’s wooden planks.

The installation wrapped up in two hours, demanded minimal paperwork, and damaged Milner’s wallet only marginally, as far as solar installations go. By noon, he plugged in an electrical cord that snaked from the panels into an outlet on the outside of his house. Immediately, solar power coursed toward his electrical panel and then flowed back through his home.

With that, he was offsetting his home’s energy use.

Milner is one of the solar-curious, who are testing the waters by purchasing a small, portable, plug-in display.

“We’d wanted to get rooftop solar, but it’s so expensive,” said Milner, a scientist. The price of rooftop solar in California ranges widely and can cost tens of thousands of dollars. “This allows us to dip our toe in a little bit without having a huge financial cost and see how it works for us.”

Plug-in solar, also called balcony solar, is a new take on an old technology. For years, panels that turn sunshine into electricity have been bolted onto rooftops and limited to people who own homes, have well-maintained roofs in prime positions, and a decent amount of cash or good credit.

But plug-and-play solar can hang from an apartment balcony, out a window, or be tented in the backyard — the smaller, more affordable displays offer an attractive alternative for renters and people with no roof at all. They may even appeal to Californians who would have bought rooftop solar but are hesitant after state regulators reduced how much someone can earn by selling excess power back to the grid.

For a long time, the economics of rooftop solar penciled out, said Bernadette del Chiaro, senior vice president for California at Environmental Working Group, who headed California’s trade association for rooftop solar for years. “I think it’s very different now for a consumer.”

On top of this, Congress’s recent budget bill reduced or eliminated solar tax credits.

Now, del Chiaro said, consumers are more likely to say: “‘I’m just going to install my own system, hang it on my own balcony and PG&E never needs to know.’”

Californians, struggling with soaring electricity bills, are eager to adopt the technology.

Advocates believe the state’s market has massive potential. They’re motivated by two examples: Utah, which recently passed legislation allowing the technology to take off once additional safety measures are implemented, and Germany, where millions of solar panels dot balconies across the country.

But there are clear hurdles, and fuzzy ones too. Utility PG&E said its customers must register the technology before they plug it in. But small solar advocates argue the registration process should be faster for these systems than it is for rooftop solar. It’s time-consuming, costly, and exactly the type of bureaucracy they’re trying to cut out.

A nonprofit called Bright Saver installed Milner’s system — it’s one of the many start-ups championing the small arrays. The organization is hoping to create a movement and plays an umbrella role for companies, policymakers and safety certification organizations.

Bright Saver’s first product is two solar panels and accessories, which can power about a fifth of the average Californian’s energy needs: covering lights and small electronics, maybe even an efficient refrigerator. It can produce 800 watts and costs $2,100, but the founders think the costs will drop in the coming years.

The organization estimates it will take Milner, who purchased his system at a discounted rate of $1,700, four to five years to make back the upfront investment in the panels through bill savings. That’s about three times faster than how long it takes to recoup the investment from rooftop solar.

Milner was motivated to try out solar because, as a father of two young kids, he wants to take action on climate change. And like most Californians, his energy bills are high, about $75 to $80 per month.

“It fixes our energy cost a little bit, because rates keep rising,” Milner said.

As easy as buying an IKEA-style table

Pranav Myana, 21-year-old founder of Zoltux, an energy company based in San Francisco, is working on his own version of this technology: a shippable set of two lightweight panels, just millimeters thick, together about the size of a medium dining room table top. Myana said you can assemble it in five minutes.

He calls it an “instant solar pod” and is pricing it at $1,199, which he estimates will pay for itself in three to four years. The company is taking pre-orders now and plans to ship the product in early fall.

Myana was inspired to build Zoltux after visiting his family’s homeland in India, a town called Sircilla, where the main industry is weaving with electric looms. When power became expensive and inconsistent, mounting debts led to many suicides that, Myana said, included some of his family members.

“It showed me just how fundamental energy was to everything we do,” he said.

Some companies like Bright Saver employ staff to install their panels, but a goal is to cut out professionals altogether. That’s because roughly half the price of getting solar is in labor and “soft costs” like permitting.

The dream is for plug-in solar to be purchased off the shelf and set up by the customer, IKEA-style.

Already, plug-in solar companies are working to add a small battery to their setups to gather extra power, store it and deploy it when the sun goes down.

But plug-in solar has risks, like most appliances. Without safety measures or proper equipment, wires could overheat and ignite a fire, or the systems could send power back to the grid when there’s a power outage, endangering a line worker sent out to make repairs.

Start-ups address these by plugging into a dedicated circuit, using a “smart plug” that can shut the solar panels off if there’s excessive current on the system, or a sensor to shut it off when the larger grid goes down.

Why isn’t plug-in solar already everywhere?

For one thing, there’s no safety standard for a complete plug-in solar system. Safety standards are typically shown by a “UL” stamp, or similar marking, on the back of products, indicating they’ve met requirements set by Underwriters Laboratories, an independent testing organization.

These exist for individual parts of the system only, which some companies assemble and view as sufficiently safe. UL said they are working on a safety standard for a full system.

Plug-in solar does not fit easily into layers of national, state and local electric code and operates in a regulatory gray area in California, where utilities want customers to register the product as they would a rooftop system.

“There’s these big gaps where it’s certainly not that you can’t do this, but it’s also not clear that you can absolutely do this,” without registering the system, said Kevin Chou, a co-founder of Bright Saver.

To stay within California rules and skirt filling out an interconnection agreement with utilities, Bright Saver’s technology prevents excess power from feeding back into the grid.

PG&E representatives said registration costs roughly $100 to $800 and shouldn’t take much time at all: just an hour if you have all your documents ready to go, with a standard approval time of three days.

Spokesperson Paul Doherty said the utility “supports new technology to make interconnecting [distributed energy resources like plug-in solar] to the utility grid as easy as possible,” but added that “it is essential” for customers to apply for an interconnection agreement, citing safety and reliability.

“They tell you you should, but they do not provide a practical means for it,” said Rupert Mayer, another Bright Saver co-founder. In Germany, customers register their name, address, system size and meter number, he added. It allows a utility to plan its electric load for a neighborhood.

“That is legitimate for the power company to want to know. But if you require someone who plugs in a single solar panel to go through the whole very bureaucratic interconnection process that they would need to go with rooftop solar,” Mayer said, as is the current case in California, “you basically make it prohibitive and put up an unnecessary hurdle.”

As his organization has grown more aware of PG&E’s interpretation of state rules, Mayer said Bright Saver has paused installations like Milner’s, at least in California, and is focused on education instead.

A breakthrough in Utah, inspired by Germany

One way to cut through the gray areas surrounding rooftop solar is to allow it, very clearly, in writing.

That’s what Utah state Rep. Raymond Ward did.

Ward wrote legislation to allow balcony solar after reading an article about its ubiquity abroad.

“I’m interested in anything that helps move towards more abundant energy,” said Ward, a Republican. “Anything that moves towards more clean power, with how that relates to the climate, is important to me.”

He championed legislation allowing people to plug in small solar arrays without a permit or utility fee, so long as they comply with the national electric code and third-party product safety standards. Products with certified components are already on the market.

The bill passed Utah’s state legislature with unanimous, bipartisan support in March. It was quickly signed into law by Republican Gov. Spencer Cox.

“It has turned out to be pretty important, right? A lot of people were watching,” Ward said.

Christian Ofenheusle is one of the architects of Germany’s plug-in solar movement. When he started in 2017, he estimated there were around 40,000 plug-in solar installations. He struggled with many of the problems facing plug-in solar in the U.S. now.

But movement leaders have made the process of getting plug-in solar straightforward through concerted effort. The product is even on sale at IKEA. Now, there are one million documented, and several million more running without formally registering with the government, Ofenheusle said.

Collectively, those panels generate the same amount of electricity as a small power plant that did not have to be built.

But even if there is widespread adoption of this technology, in terms of overall power needs, “balcony solar is a small, small piece” of overall demand, cautioned Dan Kammen, an energy professor at UC Berkeley.

Still, Kammen said plug-in solar matters, in part because “every bit helps.” And also, because panels hanging off your balcony are a talking point.

“A lot of what we do is not just signaling to others, but it’s signaling to ourselves,” he said. And it’s a way to take tangible action.

“The more you learn about solar panels for your home purchases, the more that you can translate that into the business world. And that education is invaluable,” Kammen said.

A new analysis of alerts sent during the Eaton Fire found “no failure” by emergency officials to issue timely evacuation orders to areas west of Lake Avenue in Altadena.

The timing of alerts to neighborhoods west of Lake, where all but one of 19 deaths in that fire occurred, has been under scrutiny since the January 2025 fire.

The independent report by Citygate Associates was commissioned by the L.A. County Fire Department at the start of this year and was released Monday.

Its conclusions are similar to those of after-action reports from other firms — that officials did the best they could amid unprecedented fire conditions and strained resources.

“While the report provides an honest account of our operations, we recognize that no investigation can truly capture the horror and tragedy residents endured,” said L.A. County Fire Chief Anthony Marrone in a prepared statement. “My focus is to ensure that the lessons learned from the Eaton and Palisades fires are turned into lasting changes that will better protect our residents and neighborhoods into the future.”

Altadena resident Zaire Calvin — whose sister died in the fire and whose own home burned down — said the report feels like another “slap in the face.” He said he wanted to see details on any mistakes that may have been made. But reading the report, he felt blame was once again largely placed on unprecedented fire conditions.

“A  community that's already down, a community that's fighting for their lives, a community that's fighting all of the people trying to take property from them — at some point you just want accountability,” Calvin said.

L.A. County Supervisor Kathryn Barger, who represents Altadena, said in a prepared statement that the “investigation should not be interpreted as dismissing the experiences of residents. Public trust requires both accountability and a willingness to learn from every aspect of a disaster response.”

Citygate Associates, which produced an after-action report on the 2018 Woolsey Fire, used interviews, operational records, dispatch records and internal communications to analyze decisionmaking between 9 p.m. on Jan. 7, 2025, and 6 a.m. the following day.

Some of the main findings include the following:

• With aircraft grounded by  high winds, “Incident Command was forced to fight a fire while blind to its movements.” 
• Evacuation decisions were not based on “race, age or socioeconomics.” 
• “Evacuation planners who created the evacuation zone areas well before the fire tried to use, where possible, major north/south and east/west streets. … Thus, Lake Avenue was a natural, very long street that could be utilized as an anchor for creating evacuation zones.” 
• Other fire timeline reviews cite reports of fire moving westward between 11 p.m. and just before midnight, but Citygate staffers write that strained resources were focused on the eastern front of the fire at that time, which was the direction the fire was initially spreading, and that “fire progression maps … do not show the the Eaton Fire directly impacting western neighborhoods at that time.” 
• The fire initially spread westward more slowly, and did not escalate significantly until early in the morning on Jan. 8.
• Reports of fires before 1 a.m. west of Lake Avenue were likely a result of downed power lines.
• By 2 a.m., radio reports indicated embers were being cast deeper into Altadena. 
• Discussions to expand evacuation orders west started at 2:18 a.m., with evacuation orders being sent to residents west of Lake by 3:25 a.m. 
• The main fire front crossed west of Lake Avenue by about 5:15 a.m.

Huntington Beach must pay $50,000 for each month it continues to fail to comply with the state’s mandate to zone for more housing, according to a recent court ruling. For several years now, the city has been waging a court battle against the state's order to make way for 40,000 new homes.

The judge ruled that the city should be penalized $10,000 per month going back to January 2025, and then fined $50,000 per month, starting next month, until the city gets a compliant housing element approved.

The backstory

State law requires California cities and counties to plan for enough housing to meet the expected demand over an eight-year time period, including for low-income housing. Huntington Beach, citing its independence as a charter city, has fought its most recent housing allocation all the way up to the U.S. Supreme Court, which declined to review the case last year.

Does the state require cities to actually build that many homes?

No. Cities are not required to actually build housing, but rather to make sure their zoning and land use codes accommodate the amount of housing assigned to them through what’s known as the Regional Housing Needs Assessment (RHNA).

What does the city say?

In a statement, Casey McKeon, the city’s mayor, said the city “strongly opposes these penalties and will continue fighting for the rights of our residents and for the principle of local control against ongoing efforts by the Attorney General to centralize land use authority in Sacramento.”

Is Huntington Beach an outlier?

Yes. Huntington Beach is an outlier in its aggressive fight against the state housing mandates. More than 90% of California’s 539 jurisdictions are in compliance with the state requirement to plan for the amount of housing assigned to them through the latest RHNA cycle.

What’s next?

The city recently posted draft revisions to its housing plan — for the first time since 2021. That’s significant because the city’s efforts to come into state compliance have been paused for years.

One complication with compliance: Huntington Beach residents voted to require any major changes to the city’s zoning, including its state-mandated housing plan, to be put up for a public vote. That could mean more delays in coming into state compliance, and consequently, more fines, at a time when the city is facing a budget crunch.

During a press conference following a shooting at the San Diego Islamic Center, San Diego Police Department Chief Scott Wahl confirmed three adult victims at the center and the two suspects are dead.

Police said the suspects were found dead in the vehicle nearby. They were 17 and 19 years old. The motivation behind the shooting is unknown at this time.

Wahl said in 28 years, this is the most dynamic and impressive response he's seen in policing with help coming from agencies all over the county.

Imam of the Islamic Center of San Diego Taha Hassane said the center stands in solidarity "with all of the families in our community here and all the mosques and places of worship" in San Diego.

"This is something that we never expected, and I would also like to thank all the people who contacted us from all over the country and overseas to offer their condolences."

San Diego Mayor Todd Gloria was also present at the news conference.

"We will do anything it takes to make sure you feel safe in this city," Gloria said.

In a statement, the Council on American-Islamic Relations-San Diego Executive Director Tazheen Nizam said:

“We strongly condemn this horrifying act of violence at the Islamic Center of San Diego. Our thoughts are with everyone impacted by this attack. No one should ever fear for their safety while attending prayers or studying at an elementary school. We are working to learn more about this incident and we encourage everyone to keep this community in your prayers."

The active shooter situation was reported at 11:43 a.m. at ICSD in the 7000 block of Eckstrom Avenue in Clairemont, according to SDPD.

The department is asking people to avoid the area.

A reunification location for those impacted by the incident has been established at 4125 Hathaway Street.

According to our news partner ABC 10News, authorities shut down northbound and southbound Interstate 805 at Balboa Avenue due to the law enforcement activity.

The San Diego Unified School District confirmed several campuses were placed on lock down. SDUSD spokesperson James Canning said lockdowns are gradually being lifted but schools closest to the Islamic Center will be the last to have their lockdowns lifted.

The Islamic Center is the largest mosque in San Diego County. The center holds five daily prayers.

In California’s upcoming June primary election, you’ll have the opportunity to cast your ballot for any of the candidates for governor, regardless of which party you’re registered with. The top two vote-getters advance to the general election.

Known as a “jungle primary,” this system is different from how most states handle their primary elections.

This year, Democrats raised the alarm that two Republican gubernatorial candidates may move to the general election, locking out Democrats despite outnumbering Republican registered voters almost two to one. That’s because the crowded field of Democratic candidates threatens to split the party’s vote. Until recently, multiple polls have shown the two Republicans, former Fox News host Steve Hilton and Riverside County Sheriff Chad Bianco, polling at the top of the race.

Driven in part by these concerns, critics of the top-two primary have now filed a ballot initiative that would repeal this system and return California to party-based primaries, potentially as early as 2030.

But how does this top-two arrangement work? Why does California do things this way? And what are the chances of voters choosing between two GOP candidates for governor in November?

How does California’s top-two primary system work?

In a traditional closed primary, such as in presidential races, voters can only choose among candidates from their own party: That is, say, registered Democrats could only vote for Democratic candidates.

But in a top-two primary, all candidates from all parties appear on a single ballot open to any registered voter. The two candidates with the most votes in that primary then move on to the general election, even if they’re from the same party.

Kim Alexander, president and founder of the California Voter Foundation, said this is an even bigger concern for third parties in the state.

“One of the unfortunate byproducts” of California’s jungle primary system, Alexander said, is how “it’s really shut out a lot of minor parties from the general election and they run the risk of being kicked off the ballot altogether.”

“Because if you don’t have candidates appearing on ballots at a certain pace, then you can’t remain an official party,” she said.

Does this really mean Californians might not get a Republican vs. Democrat race for governor in November?

That’s correct: Under the top-two primary system, the November contest could be an intraparty fight.

That scenario has worried many California Democrats. With seven top Democrats crowding the field, there’s a risk of fracturing their party’s vote. Meanwhile, if enough Republican voters back both Hilton and Bianco to push them both into the top two, California could be locked into an all-Republican general election for governor.

“California’s leadership on the world stage is significantly harder if a Democrat is not elected as our next Governor,” Hicks wrote in an open letter.

None of the contenders heeded his plea.

However, the likelihood of Republicans shutting Democrats out of the November election has decreased since President Donald Trump endorsed Hilton in April. A clear front-runner could unify Republican voters behind Hilton and open the door for a Democrat to claim the second spot in the runoff.

Plus, the most recent Emerson poll now shows former Health and Human Services Secretary Xavier Becerra in the lead with 19% of likely voters for the first time in the race. Hilton and Democrat Tom Steyer are tied for second with 17%.

Becerra’s surge came after former East Bay Rep. Eric Swalwell — who was regarded as a front-runner for the gubernatorial primary — exited the race last month amid sexual assault and misconduct allegations.

Why does California have this top-two system?

Historically, California required a two-thirds vote in the Legislature to pass the state budget instead of a simple majority vote.

In 2009, Democrats needed to court Republican votes to pass the state budget. Then-state Sen. Abel Maldonado, a Republican, agreed to vote yes — but only if the Legislature put a measure on the ballot to create the top-two primary system.

Voters approved that measure, Proposition 14, in 2010, amending the state constitution.

Then-Gov. Arnold Schwarzenegger backed the measure as a way to transform state politics, forcing candidates to appeal to voters across party lines and ultimately boost more moderate politicians.

“He liked to talk about living in a post-partisan political climate,” Alexander said. “He liked the idea of candidates having to appeal to more voters than just voters of their own party, and to face competition.”

The system was also designed to give more influence to California’s no party preference voters, who make up 23% of registered voters in the state, just behind Republicans at 25%.

Which political offices in California are decided using this system?

The top-two primary applies to “voter-nominated” offices: governor and other statewide positions like lieutenant governor, attorney general, secretary of state, state treasurer, state controller, insurance commissioner and state board of equalization members.

It also covers state Senate and Assembly seats and U.S. congressional offices.

The jungle primary system does not apply to presidential elections, local and nonpartisan offices such as city council, school boards, judges, district attorneys or the superintendent of public instruction.

Which other states use this system?

Washington state was the first to adopt a top-two primary for congressional and state-level elections in 2004, but not for governor.

Unlike California, Washington allows write-in candidates in the general election — a safety valve for scenarios where one party is locked out.

A handful of other states use variations of the system. Nebraska’s legislature is nonpartisan, so it uses a top-two primary for state legislative races.

Louisiana uses a majority-vote system for statewide executive offices, state legislative seats and local offices. If a candidate receives a majority of the vote in the primary, they win outright. If not, there is a second round of voting with the top two vote-getters in November.

Alaska adopted a top-four primary in 2020 for state executive, state legislative and congressional races. An effort to repeal the state’s top-four primaries was narrowly defeated by voters in 2024 but will be on the ballot again this year.

If I’m a ‘no party preference’ voter, can I even vote in the California primary?

Yes: Any registered voter, including those with no party preference, can vote for any candidate in voter-nominated races like the governor’s contest.

The top-two primary system draws no distinction based on a voter’s party registration.

Are there any efforts to get rid of California’s jungle primary?

Driven in part by concerns that Democrats could be locked out of this year’s governor’s race, a new ballot initiative seeks to repeal California’s top-two primary system.

Democratic strategist Steven Maviglio filed the initiative, called “Undo the Top Two,” with the attorney general on May 8.
He called the jungle primary a “failed experiment.”

“The prospect of having to vote for a candidate who’s not from your party in November has really woken up a lot of voters in the state about the dangers of the top-two primary,” Maviglio said. “The chance that a Democrat would have to choose between Chad Bianco or Steve Hilton is sending a chill up the spine of a lot of Democrats.”

However, even if successful, Maviglio’s initiative won’t impact the 2026 election — since he hopes to place the measure on the 2028 ballot, with any changes taking effect no earlier than the 2030 elections.
