Two projects in California will fill part of the 1,600 MW of long-duration energy storage that state regulators have said is needed by 2026.

Scientists in the United States have fabricated a solar cell using antimony selenide films with favorable crystalline properties. They achieved the remarkable conversion efficiency for this early-stage PV material by focusing on the selenization temperature.

Twenty large-scale renewable energy infrastructure projects are under construction in New York state, paving the way for it to meet its goal of sourcing 70% of its electricity from renewable sources by 2030.

In an earnings call, the company said that storage deployments grew 71% YoY and solar installations were its strongest in 2.5 years.

CS Energy and a unit of Goldman Sachs have said that their eight-project portfolio will be one of the first utility-scale solar portfolios in upstate New York, once the projects reach commercial operation in late 2021.

Scientists demonstrated two new approaches to improving the stability of perovskite solar cells. By both incorporating rubidium into the structure of the perovskite, and adding a film of two-dimensional perovskite as a capping layer, they were able to demonstrate a significant reduction in the cell’s sensitivity to moisture. The group says its research will open up new routes to improved performance and stability in perovskite PV.

The integrated power producer will sell solar power from a plant located in Gujarat to its licensed distribution business unit at a price of INR 2.22/kWh ($0.03/kWh).

A solar racking system’s strength is determined in part by the metal racking, but it also depends on the roof’s underlying structure. Rafters and any supporting structures must be strong enough to withstand your region’s maximum wind and snow loads.

A 90% clean grid with a transition to EVs would achieve lower electricity costs than one without, the study shows. Transmission investments would mainly be spur lines to new renewable generation.

The solar energy projects are expected to offset around one-third of the electric demand of Baltimore’s public buildings.
