Abstract

The easiest and most accurate way to determine the amount of incident solar energy is a measurement of the intensity of solar radiation in the given location. Necessary data on the availability of solar radiation and its energy can in principle be obtained by pyranometric measurements. An important prerequisite for results of measurements of solar radiation necessary to describe the actual relevancy of solar radiation on the site is that the measurements represent averages for a long time, as recorded by pyranometer with digital recording devices with the possibility to collect suitable number of samples in chosen time period. This work presents a system for monitoring parameters and working conditions of PV systems in real time with a perspective for monitoring of photovoltaic panels in real time application. Keywords: intensity of solar radiation, pyranometer, open circuit voltage, realtime
