Performance Study of Solar Power Source for Wireless Systems

Photovoltaic (PV) technology is an attractive power source for systems with no wired connections to any network. Because of seasonal variations of solar irradiation, designing such a system requires careful analysis in order to provide required level of reliability. In this paper we present results of 16-month measurements of experimental PV system located in Poland. Obtained irradiation values have been verified with reference data from independent sources. The results of this work may be helpful in forecasting the performance of similar PV systems in the same region and allow to make more precise forecasts of power system performance than based only on average monthly irradiation tables.
