3-D curved composite façade elements with PV: Results of a pilot project
article
This paper describes the design, manufacturing, installation and monitoring of a BIPV system that consists of coloured 3D structured façade elements, mounted on an existing office building at the High Tech Campus in Eindhoven. The façade elements contain thin film CIGS modules, which adopt the curved structure of the ele ments. The encapsulation of the PV modules into the façade elements, the colouration and the curvature led to a relative loss of about 10 % of the efficiency. The PV façade consists of 48 elements with a STC capacity of 5.8 kWp. Each element was equipped with a power optimizer, enabling individual monitoring of each façade element. The elements have been installed at the east and south façade of the building. The monitoring presented in this paper comprised a period of 5 months: the summer and autumn of 2023. The DC performance ratio during that period was 75 % for the elements on the East façade and 80 % for the elements on the South façade; which is in accordance with simplified model predictions. The result is a visual attractive retrofitted PV façade contrib uting to zero emission strategy of the Eindhoven High Tech Campus.
