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 ...

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 ...

“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 ...

As the solar industry pushes for ever-lower costs, larger module sizes and greater energy output, the structural integrity and long-term performance of modules have become critically compromised.

Scientists at the European Commission Joint Research Centre tested two single-junction perovskite modules outdoors for one year and reported overall stable performance, supported by a new ...

If you stop to think about it, it’s a marvel that we can harness energy from the sun. But we do, thanks to solar panels equipped with photovoltaic cells that convert sunlight to electricity. That’s no ...
