Performance of a Grid-Connected BIPV System at Jiangsu Province, China

This paper summarizes the operational performance results of the grid-connected building integrated photovoltaic (BIPV) system installed on the top of Yiwu international trade city in Gejiang province after ten days of monitoring. One subsystem of the BIPV system was monitored by a data acquisition system. The following parameters were measured or derived: DC current and voltage, AC current and voltage, DC and AC power, output energy, module temperature, array yield (Y_A), final yield (Y_f), reference yield (Y_f), performance radio (PR), etc. The data of solar radiance in the inclination plane of the panels and environment temperature were also collected. During the ten days of this system´s operation, the subsystem generated about 5079.6 kWh. The average AC output power per day was 508.0 kWh. The AC power generated by the inverter is proportional to the irradiance intensity. Yf ranged from 0.36 to 6.12 h/d and PR range from 0.75 to 0.89.
