The PV grid-connected demonstration system of University “Politehnica” of Bucharest

In 2006, at University Politehnica of Bucharest, in the framework of the European demonstration project PV-enlargement, and of the Romanian project ldquoPV gridrdquo, a rooftop grid-connected photovoltaic power generation system of 30 kWp has been installed. This is a double array PV system containing two kinds of silicon modules: crystalline and amorphous. The installed power of crystalline modules is of 27.36 kWp and that of amorphous modules is of 3.24 kWp. This paper gives a survey of amorphous silicon array performances during 12 representative working months under specific operational and environmental conditions of Bucharest geographical location.
