pv magazine video: How quality can lower solar risk and insurance rates

This year’s pv magazine Quality Roundtable USA looked at extreme weather, and how resiliency can be built through modern O&M. Representatives from DuPont, Stäubli, Nextracker and RETC took to the virtual stage to discuss weather-related damages, and how to harness quality materials and workmanship to industry’s advantage, particularly when it comes to insurers. Ariel Re and NovaSource, meanwhile, looked at issues like risk management insurance solutions and asset stabilization. Case studies and presentations on the field performance of PV modules, and extreme hail and fire, were also included.

A solar module stress test for all seasons

Scientists led by NREL have developed a new stress testing protocol for PV modules, one designed to simultaneously expose modules to multiple stresses, as they likely would be in the field. Putting modules through this test, the researchers have already been able to reveal new information regarding backsheet degradation, and they promise new insights into other degradation mechanisms.

Shoals, solar balance-of-system player, had a strong 2020 and sees an even stronger 2021

Dean Solon of Shoals Technologies Group: “The short version is that it’s been a damned good year.” An interview with Shoals covers the growth of large solar projects in the U.S., high AC/DC ratios and the real costs of using cheap components.

While climate change divides Democrats and Republicans, renewable policy unites

A new interactive map created by the Yale Program on Climate Communication shows the difference in responses and opinions between America’s two political parties across questions of climate change, renewable education and utility procurement.
