A total of 247 module types from 35 manufacturers have been named “Top Performers” by PV Evolution Labs (PVEL) in its 2023 Module Reliability Scorecard, more than doubling last year’s numbers and the highest ever.

PV Tech speaks to PVEL’s Tristan Erion-Lorico about the latest solar module performance trends, supply chain concerns and early TOPCon indications.

According to DuPont Photovoltaic and Advanced Materials latest ‘Global PV Reliability Study’ that focuses on field inspection and analysis of 6.5 million modules, 355 installations and 1.8GW of total power, PV backsheet material defects have increased by a significant 47% from the 2018 report.

Outsourcing in the various stages running up to module assembly versus having one’s entire supply chain in house was a major theme at PV ModuleTech 2017. PV Tech caught up with Nick Strevel, director, global technical sales, at vertically-integrated thin-film PV manufacturer First Solar, to discuss the benefits of having all in house production and the drivers for high expenditure in R&D.

DuPont, an industry leader in high-performance materials for photovoltaic panels, shares Bill of Materials (BoM) specification recommendations based on extensive field observations and laboratory testing.
