World record efficiency for Longi’s PERC mono, Jinko’s p-type PERC and bifacial solar panels
Solar module efficiency records continue to fall. Longi claims a 22.38% efficiency world record for a PERC mono panel, while Jinko has achieved conversion efficiencies of 21.82% and 22.49% for its p-type PERC and n-type HOT bifacial panels, respectively.
Morning Brief: Virginia fills third-party pilot, S.C. House calls for Santee Cooper to go clean
Hello one and all and welcome to the first morning brief of your work week. Today we have BoxPower delivering microgrids to earthquake-affected communities in Puerto Rico, and Sullivan Power winning an award for its UC Irvine installation.
Dan Shugar, NEXTracker CEO, on solar trackers in wind and the terror of torsional galloping
In the final part of our interview, Dan Shugar, goes into detail about a subject NEXTracker has studied in depth — static and dynamic evaluation of wind impacts on single-axis trackers. We include video of trackers (and a bridge) caught galloping in the wind.
Kresge Foundation backs solar+storage for buildings housing low-income residents
To help safeguard residents’ health and comfort during an extended power outage, a new program will provide loan guarantees for solar+storage installations that could keep cooling systems, medical equipment and refrigerators running.
Hawaiian Electric plans for 70% renewables by late 2020s, exceeding targets
To integrate an increasing percentage of renewables, Hawaiian Electric has turned to a standard solar+storage framework, matching all new solar capacity with an equal capacity of storage with four-hour duration.
A desert solar farm can actually improve desert tortoise habitat
With tortoise-sized openings at the bottom of the fence, and improved growth of plants vital to tortoise survival, a solar farm in Nevada can provide better habitat than the surrounding desert. First Solar found similar habitat gains in California.
Not just for outer space: NREL has a path to cheaper GaAs solar cells
A team at the U.S. National Renewable Energy Laboratory has come up with a new process that would reduce the production cost of highly expensive – and highly efficient – gallium arsenide cells.
Photo gallery of Tesla solarglass roof tile installations: Will 2020 be the year of the solar roof?
Tesla shipped a record number of electric vehicles in the most recent quarter and started production at its new China factory. However, 2019 was not “the year of the solar roof,” despite Elon Musk’s aspirations. Your humble narrator tracked down some solar roof installations to witness Tesla’s solar glass in the wild. We’ve got pictures.
Battery roundup: funding for zinc-based storage, improved lithium-ion, new solid-state batteries
Venture capital is still flowing to energy storage startups and the march to improve a wide variety of battery chemistries continues.
US scientists claim clear-sky irradiance model provides better results for module testing
Researchers at the American Institute of Physics have used the clear-sky irradiance model developed by the National Renewable Energy Laboratory to measure the degradation rates of solar panels at a testing field in Germany over five years. The scientists say the model, when combined with real-world data, offers an efficient tool to evaluate the aging of PV technology.
