Fire at California’s Moss Landing battery plant triggers evacuation

The cause of the fire has not yet been determined, but an investigation will begin once the fire is extinguished.

The impact of wildfires on PV power generation

Scientists have quantified the impact of wildfires on the availability of direct normal irradiance and global horizontal irradiance at the state, regional, and national levels in the United States. They have found that direct irradiance is more sensitive to smoke than the PV-relevant global horizontal irradiance.

California winery installs solar with dual-axis tracking

A winery California will cover 95% of its electricity needs with a solar array that tilts on two axes to follow direct sunlight through the day.

‘High electricity prices in California have nothing to do with renewables’

Stanford University professor Mark Z. Jacobson spoke to pv magazine about recent research work showing that California could easily rely on a wind-water-solar-dominated large grid. He says the state’s current electricity prices are high because of several reasons that have nothing to do with renewables. These include high fossil gas prices and the cost upgrading aging transmission and distribution lines, among others.

The Hydrogen Stream: US government, ABI Research predict lower H2 costs

The US government says electrolysis could reduce clean-hydrogen production costs to $1/kg by 2031, while ABI Research claims the global levelized cost of hydrogen (LCOH) will become cost-competitive by the end of this decade, dropping to $2.50/kg.

Enphase Energy rolls out software to prevent busbar overload

Enphase Energy has released new software to help homeowners install larger solar and battery systems without major electrical panel upgrades. It uses real-time measurements from current transformers to make immediate decisions.

California’s new community solar program still isn’t working

pv magazine USA spoke with Aaron Halimi, founder and president of Renewable Properties, and Derek Chernow, Western Regional Director for the Coalition for Community Solar Access, about the impact of California Public Utilities Commission’s final decision on the state’s community solar projects.

California utilities scapegoat rooftop solar for high electricity rates

Utilites in California and nationwide are fighting rooftop solar, the major threat to their effective monopoly on the electricity market, said the California Solar and Storage Association (CALSSA).

Solving the UV problem of n-type solar

Laboratory testing has revealed that some negatively-doped, “n-type” tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) solar modules are susceptible to ultraviolet (UV) light-related damage and degradation. That could mean trouble down the line, if modules in the field begin to show UV-related performance loss. Manufacturers are implementing solutions at cell and module level.

Powering restaurants with rooftop PV, reversible fuel cells

Researchers have simulated the operation of bifacial PV and proton exchange membrane reversible fuel cells across restaurants in five different US states. Taking into account varying rates of bifacial PV’s rearside gains, they found that LCOE was as low as $0.029 per kWh.
