Also on the rise: Sunrun fined for worker rooftop safety violation. DC Grid debuts off-grid DC solutions to address growing power demand. And more.

Residential solar installer Sunrun was penalized for its failure to adhere to OSHA roof safety practices.

These Missouri and Texas projects contribute to the growing portfolio between Meta and DESRI.

A letter to California Governor Gavin Newsom addresses the state’s electricity affordability crisis – and a misconception that rooftop solar is to blame for the high costs.

Primergy Solar’s 100 MW solar project in Ashley County, Arkansas is fully operational.

With manufacturing based in Texas, the company reports that this is the first foundation system to meet 100% domestic content standards, thus potentially qualifying for the domestic content adder.

Also on the rise: Perovskite-silicon solar cell achieves 28.6% efficiency, ready for mass production. Energy experts urge California Governor to reject anti-rooftop solar executive order. And more.

South Korean manufacturer Qcells has developed a perovskite-silicon tandem solar cell with a 28.6% efficiency, noting that it was “fabricated by exclusively using processes that are feasible for mass production.”

Newly formed NuVision Solar is a U.S.-owned and operated manufacturer with plans to produce HJT solar cells and modules.

Also on the rise: Solar and storage on military bases. Survey captures wide-spread optimism for solar’s future, but respondents divided over AI. And more.

The newly launched Mountain View, California startup is betting its DC modules can help circumvent interconnection queues.

Firms building datacenters to train artificial intelligence models could power the centers with high-solar microgrids in the southwest U.S., researchers found. The power demand for such datacenters is estimated at 15 GW to 150 GW by 2030.

The big milestone comes on the back of a record month for electric vehicle sales and strong battery energy storage system (BESS) deployment. However, EV demand remains far behind BESS with the latter’s impressive growth reaching a year-on-year increase of 175% and cumulative 19.4 GWh deployed in November alone.

Anti-dumping, countervailing duties on battery materials could have serious effects on the EV and energy storage markets, as the battery material and manufacturing markets in the U.S. are still in very early stages.

The Arizona Corporation Commission approved a nominal grid access fee for rooftop solar customers. The charge is a few dollars each month – but utility APS said it wanted the charge to be as high as $88 per month.

The proposed cell is based on indium gallium phosphide (InGaP), indium gallium arsenide (InGaAs) and germanium (Ge) and has an active area of 0.25 mm2. It can be used for applications in micro-concentrator photovoltaics (CPV).

By using a “robust” approach to planning for new renewable and storage capacity to meet future energy demand, stakeholders can identify low-cost portfolios that can be quickly tested against various cost scenarios, said Derek Stenclik of Telos Energy.

As the heavy majority of the U.S. energy grid approaches the end of its lifecycle, the time is now for a public-private task force to develop a comprehensive strategy to harden the grid and enable technologies that maximize the benefit of targeted investment in the most vulnerable areas.

SunTrain is hoping to ship renewable energy via battery-powered trains, charged from solar and wind, using rail networks.

New patents to integrate artificial intelligence into global grids have grown sixfold over the past few years, with China driving overall innovation momentum. The European Patent Office, co-authors of the report, called for Europe to renew its efforts.
