PVEL

Looking into the cracks

A white paper published earlier in December by PV Evolution Labs investigates the formation of performance damaging cracks in PV cells, based on mechanical stress testing of more than 40 commercially available PV modules. While the lab warns that susceptibility to cracking will change according to the specific bill of materials making up each module, certain technologies are shown to perform better than others.

Nextracker inks 1 GW supply deal and claims up to 12% bifacial yield gain

The 1 GW fifth phase of the Mohammed bin Rashid Al Maktoum Solar Park in Dubai will feature NX Horizon trackers with the deal announced after the manufacturer published new bifacial yield gain claims.

A common language for bifacial PV

This week pv magazine was in Amsterdam for the sixth edition of the BifiPV workshop, where the discussion focused on the impressive achievements made by bifacial solar modules and the challenges the technology faces as it moves toward mainstream adoption.

The weekend read: Inverter issues

PVEL’s inaugural inverter scorecard is showing up the need for much more scrutiny on the reliability of inverters. But are developers and EPCs even paying attention?

Battle of the module reliability rankings

While PV module makers are attempting to get the best possible scores for their products on 3rd party tests, 3rd-party testing providers are also offering competing products to rank products. We look at what’s similar and what’s different in the tests.

PVEL looks at the risky business of inverters

The testing company’s first inverter scorecard found widespread failures of basic tests in UL- and IEC-tested products.

PV Evolution Labs to go it alone again outside DNV GL

The PV panel testing company has left the fold four years after being acquired by DNV GL. Insiders have stressed the move should not be problematic as PVEL was allowed a degree of independence after it was acquired.
