摘要: Abstract The standard efficiency of photovoltaics (PV) often deviates from the one achieved under real outdoor conditions. This paper presents relevant data collected using a small multi-crystalline photovoltaic array at an experimental facility located north Athens. Measurements during summer and winter periods were used to quantify PV performance operating characteristics. Several correlations are provided in order facilitate estimation actual with readily available local parameters (e.g. ambient air temperature, wind speed). was found be about 18% lower than that laboratory test conditions, similar mean annual 8.7%.
