Rooftop solar energy is essential to helping California meet its goal of generating 100% clean electricity by 2045.

Re: Support for AB 2256 (Friedman): the true value of rooftop solar

We as the undersigned write in enthusiastic support of Assembly Bill 2256 (Friedman).

We have the power to harness abundant renewable energy from the sun by installing solar panels on California’s rooftops. While we lead the nation in rooftop solar capacity, we’ve only taken advantage of 10% of the state’s rooftop solar potential so far. Rooftop solar energy is essential to helping California meet its goal of generating 100% clean electricity by 2045.

California’s highest court granted review to a lawsuit challenging a “regressive” rooftop solar policy called NEM 3.0.

A controversial rooftop solar rulemaking decision has risen to the Supreme Court of California, with the state’s highest court granting review for a petition filed by the Center for Biological Diversity.

The case involves the state’s NEM 3.0 net metering scheme and the rate structure that went into effect in April 2023. The California Public Utilities Commission (CPUC) approved a request by the state’s largest investor-owned utilities to cut compensation to customers that export excess solar generation to the grid, a process called net energy metering.

California ranks as the “greenest” state in America according to a report released Wednesday by the WalletHub personal finance website.

California ranks as the “greenest” state in America thanks to rooftop solar, water conservation and electric vehicles, according to a report released Wednesday by the WalletHub personal finance website.

“Eco-friendliness and personal finance are related,” noted Miami-based WalletHub in its introduction to the ranking. “Our environmental and financial needs are the same in many areas.”

States were ranked on environmental quality, eco-friendly behavior and contribution to climate-change using 25 metrics ranging from water quality to LEED-certified buildings to greenhouse gas emissions.

Elevated metro stations may highly benefit from rooftop solar power generation combined w/ battery storage, new research from China suggests.

Researchers from the Xi’an Jiaotong University in China have investigated how rooftop solar and battery storage may help cover energy demand in elevated metro stations and found this combination may achieve a self-sufficiency rate of up to 54% and a payback time of 10.2 years.

“Our work is the first study focusing on the PV potential of elevated subway stations based on real energy loads,” the research’s lead author, Haobo Yang, told pv magazine. “Our findings are based on measured hourly load demands and include the impact of battery energy storage on PV system performance.”

In the study “Technoeconomic analysis of rooftop PV system in elevated metro station for cost-effective operation and clean electrification,” published in Renewable Energy, Yang and his colleagues said their work is intended to provide a benchmark for cost-effective operation and clean electrification in urban metro networks.

India is renewing its push to add rooftop solar to meet the needs of a fast-growing nation that's hungry for energy.

Just a few years ago, someone who wanted to install a rooftop solar connection in India faced getting multiple approvals, finding a reliable company to install the panels and spending heavily before seeing the first surge of clean energy.

But that’s changing. The government has streamlined the approvals process, made it easier for people to claim subsidies and pushed mountains of cash — including $9 billion announced this month — to encourage faster adoption of technology that’s seen as critical for India to reach its clean-energy goals.

VNEM incentivises builders to adopt rooftop solar and share the benefits – both financial and environmental – back to renters.

Most large cities in the US are facing a tri-fold crisis of housing, energy, and affordability including cities in New York State, California, Colorado, and others. Many residents in these cities face a lack of available housing combined with income inequality, which is exacerbated by the rising cost of basic expenses, particularly detrimental for renters. Plus, it’s no secret that Americans across the nation bear the brunt of an aging energy infrastructure, experiencing more frequent power outages and high energy bills due to rising and volatile energy prices.

The good news is that there’s a single existing programme that can help tackle all three of these issues: Virtual Net Energy Metering (VNEM).

After CA gutted how much households are paid for excess solar power, Puerto Rico preserves net metering for clean energy & resilience.

As states across the country roll back how much they pay rooftop-solar owners for the surplus electricity they send back to the grid, Puerto Rico is bucking the trend, protecting its generous solar credits until at least the end of the decade.

California, Arkansas, Idaho, Indiana, and North Carolina have all taken recent steps to change or get rid of these payments, which are known as net metering. But Governor Pedro Pierluisi signed a bill last month extending the U.S. territory’s program. The reason, advocates say, is that net metering is too essential to the archipelago’s clean energy goals, and the security of its people.

Three groups challenge an appeals court ruling that upheld the California Public Utilities Commission’s NEM 3 decision.

Despite being turned back by the California Public Utilities Commission and an appeals court in San Francisco, three groups have taken their fight to overturn recently passed rules regarding rooftop solar to the California Supreme Court.

The San Diego-based Protect Our Communities Foundation joined the Environmental Working Group and the Center for Biological Diversity in filing a petition for review Monday afternoon with the high court.

The groups argue that a decision issued last month by the First Appellate District wrongly upheld the utilities commission’s vote that overhauled net energy metering guidelines, which determine the compensation that solar customers receive when their systems generate more energy than they consume.

According to forecasts from Wood Mackenzie, California’s residential solar market will see a 40% decline in 2024.

California’s rooftop solar and storage market is changing, and the industry is learning to operate in this new reality.

California has been America’s top solar market for over a decade, installing more solar capacity than any state every year until Texas took over in 2021. While California reclaimed the number one ranking in 2022 and installations look strong in 2023, the shift in 2021 may be a preview of what is to come.

In late 2022, after years of debate, the California Public Utilities Commission (CPUC) unanimously approved a new way to compensate rooftop solar customers for the excess energy they generate. This decision moves the state from retail rate “net metering” to a new “net billing” structure that cuts the value of rooftop solar credits by about 75%.

A new 1.5-megawatt solar array will be installed atop a warehouse in Panorama City that will generate renewable energy to power 200 homes.

With a flip of a ceremonial switch, Los Angeles elected officials, business leaders, and community partners celebrated one of the largest rooftop solar panel systems to be installed in the Northeast San Fernando Valley – a new 1.5-megawatt solar array atop a warehouse in Panorama City that will generate enough renewable energy to power 200 homes.

The Valley project is the latest to take advantage of the Los Angeles Department of Water and Power’s (LADWP) Feed-in Tariff (FiT) solar program, which enables building owners to create solar power plants on their rooftops and sell the power they generate to the Department for distribution on the city’s power grid.
