Joule heating estimation of photovoltaic module through cells temperature measurement

Module temperature has a role in determining PV module's performance. The purpose of this paper is to estimate the Joule heating photovoltaic (PV) module by comparing during PV-On (electricity generation) and PV-Off (without electricity generation). was less evaluated due simplifying formulation, which easier implement experimental observation as proposed work. experiment collected distributions PV-Off. distribution follows normal curve irradiation uniformity pattern solar simulator slight ≤0.3 oC difference between slightly increased 0.53 K/A, proportional irradiances. almost seven times from 2.65 W at 700 W/m2 18.07 1000 W/m2. might increase overall thermal conductivity decrease resistances. It affect heat transfer. This research may improve procedures prediction or photovoltaic-thermal (PVT) collector considering heating.
