Monitoring degradation for 13 module types

In a study that began in 2016, US scientists purchased 834 PV modules, representing seven manufacturers and 13 module types, and installed them in various climate conditions to observe their performance over time. The results show that, while plenty of opportunities still exist to extend module lifetimes and reduce performance loss in the field, reductions in the manufacturing cost of PV have not come with an increase in their degradation rate.Any change to the contents of a PV module - whether moving to an entirely new cell technology, or simply changing the thickness of the glass in front of ...
