Install grid-connected solar, rinse, repeat
Will a redeployable solar and energy storage solution be the answer to unreliable grid electricity across much of Africa, as its developer proposes? Or will it merely be a temporary solution that will see cash-strapped utilities kick the can of universal energy access further down the road?
Longi claims 33.9% efficiency for perovskite-silicon tandem solar cell
The US Department of Energy’s National Renewable Energy Laboratory (NREL) has confirmed Longi’s achievement of a world record-breaking efficiency rating of 33.9% for a perovskite-silicon tandem solar cell.
Solar cell prices plunge to all-time low
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Ensuring a just and inclusive energy transition for the Global South
Amid calls for an immediate transition to renewable energy, it’s important to ensure that aspects such as domestic resource utilization, the cost of transition, and the impact on the population are not overlooked.
HDF Energy to produce fuel cells in France, hydrogen in 30 countries
HDF Energy has expanded its operations to make fuel cells in France. It says it plans to produce green hydrogen infrastructure for low-carbon hydrogen production and non-intermittent renewable electrical power in 30 countries throughout the world.
Sharp claims 33.66% efficiency for silicon tandem solar cell
