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.
Maintaining quality, reliability and durability in the solar supply chain
At the pv magazine Roundtables US 2023, four experts weighed in on the importance of testing, inspection, standardized data and more, in the never-ending quest to build a reliable and resilient solar industry.
Sunrise brief: Annual U.S. clean energy investment grows 37%
Also on the rise: Plus Power raises $1.8 billion to advance construction of five energy storage facilities. Solar power purchase agreement prices rise 21% year over year. And more.
New opportunities for 4-hour-plus energy storage
Energy storage with more than four hours of duration could assume a key role in integrating renewable energy into the U.S. power grid on the back of a potential shift to net winter demand peaks, says the National Renewable Energy Laboratory (NREL).
Grid-forming inverters will enable a high-renewables grid
As renewable generation increases, so does the need for grid-forming inverters to provide the same functionality that rotating synchronous generators provide. The UNIFI Consortium is coordinating industry progress on the new inverter technology.
Sunrise brief: New website provides automated engineering stamps for residential solar
Also on the rise: Building not your average dream home. APsystems releases AC-coupled residential battery charger. And more.
Large solar projects have no negative impact on property values, study says
A study commissioned by Conservative Texans for Energy Innovation, Advanced Power Alliance and the Solar Energy Industries Association looked at market trends near six utility-scale solar projects.
Sunrise brief: Utility-scale project updates for booming Texas solar market
Also on the rise: Toledo Solar and First Solar reach agreement in lawsuit. Massachusetts can save 4.6 million metric tons of carbon by changing solar development strategy. And more.
Virginia utility’s resource plan needs more solar and storage, says trade group
The trade group Advanced Energy United called on Virginia regulators to reject Dominion Energy’s proposed resource plan because it lowballed renewables and storage. The Sierra Club said 15 GW more solar and 5 GW more storage by 2038 would be optimal.
HVDC transmission serves mostly wind and hydro power, not solar
A report from The Brattle Group and DNV recommends clearing barriers in the U.S. to high-voltage direct current (HVDC) transmission. HVDC transmission projects show many cost-saving use cases, but so far, transmitting solar power is rarely among them.
