Tesla was once the unquestioned leader in the U.S. residential rooftop market with a market share of around 33 percent, but today, the company is No. 3, and its market share during the first quarter was a little more than 6 percent.

According to new research, metal chalcogenide perovskites can be used as a thermoelectric material than can convert thermal energy from the sun to usable electric power. These materials, which can also be used to develop perovskite PV cells, are known for their high thermal and aqueous stability, along with their nontoxic elemental composition.

In what has been a crazy year for Nevada, the Public Utilities Commission is ending on an equally insane note by proposing 1 GW of energy storage to be deployed across the state by the last day of 2030.

With almost a decade having passed since electric vehicles hit public roads, the price of battery packs has dropped 87% since 2010, according to a report by Bloomberg New Energy Finance. With rising efficiency and evolving supply chains, the market research group suggests cumulative demand will bring prices down to parity with internal combustion engine vehicles by 2024.

The solar project, southeast of Seville, will power Amazon Web Services data centers and logistics locations, and is expected to start generating next year. The company has launched its Climate Pledge with the aim of complying with the Paris Agreement 10 years early by neutralizing carbon emissions by 2040, and of operating with 80% renewable energy by 2024 and 100% renewable energy by 2030.

The U.S. business built and sold record-setting gallium-arsenide solar cells but its parent has seemingly run out of patience. Having failed to give its workers notice of the move, Hanergy is either in contravention of U.S. employment law, ‘faltering’ or subject to ‘unforeseen business circumstances’.

pv magazine group welcomes Eric Wesoff as the new editorial leader of the U.S. platform. With two decades of experience working in the renewable energy industry, Wesoff brings a plethora of expertise in solar power, advanced batteries, clean technology investing and finance, utility structures, and the electric grid.

Black Hills Energy is seeking 200 MW of solar power or wind plus energy storage capacity as part of a request for proposal, driven by summer 2019 bids for solar+storage of $0.024/kWh and $0.036/kWh and looming cuts to the 30% investment tax credit.

Researchers at the U.S. Argonne National Laboratory have applied a combination of machine learning and artificial intelligence to help narrow down a list of 166 billion molecules that could be used to form the basis of a battery electrolyte. The technique, say the researchers, offers a way to greatly reduce the cost of narrowing down such an enormous data set, while still providing a precise understanding of each molecule and its likely suitability.
