Microinverter supplier Enphase is slipping in share price as revenues dip. It has announced a $1 billion stock buyback program.

Weidmüller USA, a manufacturer of electrical connectivity solutions, has introduced new PV DC Combiner Box models for large-scale PV systems in the US.

A Colorado farmer has installed vertical bifacial solar, leveraging greenhouse albedo to increase output. The installation demonstrates promising generation during winter months, while maximizing limited land space.

The world would have been a different place today had John Goodenough accepted the Shah of Iran’s $7 million offer, in 1974, to carry out solar research. Instead, he secured a job as the head of inorganic chemistry at the University of Oxford. During his tenure, he made a lithium-ion battery discovery that would affect the lives of almost everyone.

First Solar has revealed plans to open its fifth factory in the United States. The new facility is expected to add 3.5 GW of annual production capacity at a cost of $1.1 billion.

AES Indiana filed for a 200 MW/800 MWh battery project, which is slated to be the largest in the US state of Indiana. It will be located at the site of a partially decommissioned multi-unit coal plant that is now transitioning to gas.

Researchers at Argonne National Laboratory and the US National Renewable Energy Lab (NREL) have found that renewable energy can reduce the cost and emissions of electricity in remote parts of Alaska.

Meyer Burger plans to start a 2 GW cell factory in Colorado in the fourth quarter of this year.

NREL researchers used acoustically spalled gallium arsenide substrate that reportedly reduces electrical shunting, resulting in potentially lower manufacturing costs. The cell achieved an open-circuit voltage of 1.061 V, a short-circuit current density of 29.9 mA/cm2, and a fill factor of 84.9%.

Georgia Institute of Technology researchers have used aluminum foil-based negative electrodes with engineered microstructures in an all-solid-state lithium-ion cell configuration. They have reported hundreds of stable cycles with practically relevant areal capacities at high current densities.
