Sizing and Testing of Stand Alone Photovoltaic Systems

Based on the analysis of a 43 years irradiation data serie (Dresden) sizing rules for stand alone PV systems are presented. Values of sizing irradiation and system autonomy are derived from the statistical analysis, taking into account realistic properties of the PV system components. These data seem to bee applicable to larger regions of Gemany and middle Europe. The sizing rules are compared with experimantal results and with results of simulations.
