Choosing representative strings for measuring power loss

Analyzing monitoring data does not always accurately identify under-performing assets; and when investigating supposed power loss with IV-curve measurements, a representative sample via thermography should be selected. These are two conclusions drawn from a case study, which will be discussed during the upcoming asset management session at the pv magazine virtual roundtable Europe 2020.

Designing super-strong solar modules for the tropics

An international research team has defined the operational parameters needed to design and manufacture crystalline silicon PV modules for tropical climates. The group proposed a back-junction, back-contact cell tech with a selective laser soldering technique it claims offers the best potential to yield such robust panels.

Filling in the (micro)cracks

Whether caused by improper production processes, poor treatment in transport and installation, climate conditions or any other issue, performance reducing microcracks are a major source of stress for PV developers and project owners. Now, an EU funded research project has found that a different type of stress could provide a solution, and even “heal” some existing cracks.
