Analysis of Hot-Spots Effects on the Performances of a Photovoltaic System Used in Romania

Abstract

This article presents an analysis of hot-spots effects onevr the performances of a photovoltaic system in use. IV and P-V characteristics are analyzed considering different cases of degradation for the photovoltaic module (few hot-spots, large number of hot-spots and highly damaged module). Simualtions and experimental data are presented and analyzed considering the energetical performances.
