CS Energy, Goldman Sachs bring more than 200 MW of PV to New York
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.
Doping and capping promise perovskite stability
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.
Torrent Power secures PPA for 300 MW solar capacity in India
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).
Solar 101: Attaching your PV system to your roof
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.
Add electric vehicles, not bulk transmission, for a low-cost, clean grid: UC Berkeley study
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.
SunPower builds two brownfield solar projects in the US
The solar energy projects are expected to offset around one-third of the electric demand of Baltimore’s public buildings.
GM and LG Energy plan a $2.3 billion electric vehicle battery plant
The automaker’s future Ultium-powered EVs are designed for Level 2 and DC fast charging. Most will have 400V battery packs and up to 200 kW fast charging capability.
Pollinator-focused solar parks
Researchers in the US ascertained that the partial shading provided by solar parks creates a microclimate that favors the abundant growth of more varied flowers and pollinators. They also found that partial shading increases bloom abundance by delaying bloom timing, increasing forage for pollinators during the hot and dry late season.
US start-up secures distribution agreement for nickel-hydrogen battery technology
EnerVenue signed its first major distribution agreement with Hong Kong’s Towngas. The deal will pilot the company’s nickel-hydrogen battery technology and serve as an audition for future deals to come.
Walmart adds 6.5 MW of rooftop and canopy parking solar to California stores
The $10 million portfolio was developed by Sol Customer Solutions and will deliver energy to seven stores across the state.
