Every solar panel company makes bold claims about its panel efficiency, maximum wattage availability, temperature coefficient and other specs in optimal conditions. Anyone who does product testing ...

NASA’s Lucy spacecraft has successfully completed thermal vacuum testing of both solar panels, the final step in checking out these critical spacecraft components in preparation for launch this fall.

In 2024, researchers at Fraunhofer ISE analyzed the stability of TOPCon, passivated emitter and rear cell (PERC), and heterojunction solar cells under UV irradiation and found that all three cell ...

The solar industry has fought for decades to earn its reputation as the fastest, cheapest way to decarbonize the grid. But in 2025, as deployment accelerates and policy support wanes, the industry ...

The US-based developer of copper indium gallium selenide thin-film PV products said its modules will be tested without modifications by companies developing marine PV and power beaming applications.

“Four years ago, that was at 50% and it’s steadily increased since,” said Tristan Erion-Lorico. Image: Kiwa PVEL. A total of 83% of module manufacturers have had at least one test failure in the Kiwa ...

The reliable performance of PV modules is heavily influenced by the climate conditions in deserts, which include factors such as irradiance, temperature, humidity and dust soiling. Image: DEWA R&D. A ...

Solar panel efficiency determines how much sunlight your panels can turn into electricity and how much you’ll save on bills ...

Technicians dismantled the vintage 10-square-meter 1-kilowatt solar array last year, running the solar panels through rigorous lab testing per international standards and finding impressive results.

The U.S. solar industry has entered a high-stakes era where policy compliance and supply chain integrity are just as critical as project economics. Day 2 of pv magazine USA Week 2025 dives into this ...
