In this first progress report of the analytical monitoring of the titlesystem the results of the measurements in the period 5 September 1997 - 1 December 1997 are presented. During the measuring period the photovoltaic (PV) system did not break down. The nominal capacity of the 44 PV-modules is 2090 Wp. The inverter capacity is 1500 W, which is underdimensioned. In case of high solar radiation the generated capacities do not correlate with the intensity of the solar radiation because of the limited inverter capacity. The annual energy yield is 2.1% lower compared to a non-underdimensioned inverter. The performance ratio is circa 0.81. The average efficiency of the inverter is 89%, the low radiation losses are 5.1%. The problem of the measurement of the inverter efficiency in case of high solar radiation has not yet been solved.
