How accurate are temperature measurements of PV modules to estimate the cell temperature?
conference paper
The aim of this work is to investigate how representative module temperatures at the rear side of a photovoltaic (PV) module are of the cell temperatures within the modules deployed in the field. To assess the in-situ cell temperature, in-situ optical sensors based on the Fibre Bragg Grating (FBG) principle were embedded into the module using the novel PV-sense packaging [1] and compared to thermocouples at similar positions at the back of the module. Combined with full weather and environmental data, we could then draw a valid comparison.
