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 ...

A research group in Japan identified a correlation between damp heat test of 1,000 hours to 3–6 years of field exposure in humid areas and changes in acetic acid concentration in photovoltaic modules.

“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 ...

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.

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.

Portable solar panels neatly ride the line between fallback options during a power outage and convenient sources of electricity on the go. Solar power is the fastest growing source of electricity in ...
