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.

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.

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.

Is First Solar stalled in innovation and growth? Markus Beck, a thin-film solar expert and former chief scientist at First Solar, provides an industry perspective on the fate of thin-film PV in the U.S.

Venture capital is still flowing to energy storage startups and the march to improve a wide variety of battery chemistries continues.

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.

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.

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.

Certain articles at pv magazine strike a chord with readers and spark greater discussion among the community. Here are the most discussed articles of 2019 at pv magazine USA.

Lora Kolodny at CNBC uncovered a recently granted building permit that allows Tesla to put up “two canopy covers” over its new “solar test houses.” Earlier this year, Tesla CEO Elon Musk announced that 2019 was “the year of the solar roof.”
