Panasonic claims 16% efficiency for lightweight perovskite solar module
The device has an area of 802cm² and thickness of 2mm. The manufacturer claims it improved module performance through an inkjet coating method and a reduction in weight by using thin glass substrates.
Dirt-eating solar panel coating wins government funding
Swift Coat has won a $1 million grant from the DOE to develop a solar glass coating that combines industry standard anti-reflective properties with photocatalytic titanium dioxide that breaks down organic materials on solar modules, potentially increasing energy generation by 3% over standard panels.
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.
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.
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.
Shutdown continues at Hanergy-owned Alta Devices, high-efficiency PV pioneer
Alta Devices has not located a white-knight investor to save the company and resume its PV cell production. That means no health care or COBRA for its furloughed employees.
Ten research teams aim for long-duration storage at 5¢/kWh
To get long-duration storage costs down to 5 cents per kilowatt-hour, research teams funded by ARPA-E are pursuing breakthroughs in flow batteries, hydrogen storage and other technologies—even thermovoltaics.
