Analysis of Photovoltaic Modules Characteristics

Abstract

Nowadays, photovoltaics is one of the most popular and interesting areas, especially in the economy. This paper presents an analysis of characteristics of photovoltaic modules. The comparisons between the characteristics provided by the manufacturers and characteristics obtained by measurements, under the real time conditions are accomplished. The temperature dependence of power and the actual energy production are also presented. Measurements are obtained directly from the module without the inverter.
