Performance Analysis of the BIPV of an Industrial Park in Wuhan

Abstract

The performance of BIPV system is a crucial factor for its development. This paper chooses PV arrays installed on an industrial park buildings in Wuhan as a research object. The performance of PV array has been investigated at different tilt angles and orientations on the meteorological conditions of Wuhan. The performance of the amorphous silicon BIPV system and that of the polysilicon BIPV system are presented. The two BIPV systems are both 30 kW, with a tilt angle of 20° and facing south. The performance analysis shows that average monthly output energy of the polysilicon system and that of the amorphous silicon system are 2440.85kWh and 2209.14kWh respectively. The performance of amorphous silicon BIPV system is better in May, June, July and August. The maximum monthly output energy can be obtained in August (3768kWh and 3308kWh).For the amorphous silicon BIPV systems facing south and with different tilt angles of 20° and 10°, more output energy can be obtained from the amorphous silicon BIPV system with a tilt angle of 20°. The performance of the amorphous silicon BIPV systems oriented facing south with a tilt angle of 10° and that of the amorphous silicon BIPV systems oriented facing north with the same tilt angle are also analyzed respectively in this paper. These analyzes will provide a reference for the development of BIPV in Wuhan.
