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 ...

Ryan Mayfield led an informative discussion on the history of the NEC PV Hazard Control System rules and the latest changes to the UL 3741 standard.

The researchers found that the 50-50 recycled modules performed as well as the panels made with virgin glass. Image: Solarcycle US solar PV recycling firm, Solarcycle, has produced a pilot module ...

Once considered isolated incidents, spontaneous glass breakages in solar modules are becoming more frequent, highlighting the limits of some manufacturing choices and the need for closer quality ...

“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 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 ...

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.

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 ...

We tested 20 solar generators to find the most versatile devices that can provide emergency backup power and fuel off-grid activities. Three came out as the best.
