Before a PV Lifetime system is installed all the modules are characterized indoors on a flash simulator at standard test conditions (STC). Every year afterwards a sample of modules are removed from the arrays and re-characterized. All this data will eventually be made available. Guidelines for determining the relationship between sample sizes and uncertainty in…

Introduction Started in 2016, the PV Lifetime Project is measuring PV module and system degradation profiles over time with the aim of distinguishing different module types and technology. Outdoor energy monitoring in different climates are supplemented with regular testing under repeatable test conditions indoors. The focus is the PV module, as well as other hardware…
