Abstract

We address the problem of modeling the thermal behavior of photovoltaic (PV) cells that, due to their being exposed to shading, may experience a dramatic temperature increase (a phenomenon referred to as hot-spot) with consequent reduction of the provided power. Our proposed model has been validated against experimental data, and constitutes a first preliminary step towards the development of shading-tolerant approaches, while also highlighting a counterintuitive PV cell behavior useful to energy efficient PC array design.
