Picture: EMSD Install Hong Kongs Largest Solar Array

A 350kW solar photovoltaic installation at the Electrical and Mechanical Services Department Headquarters has been installed on the roof of their new headquarters in Kowloon Bay. The installation, being the largest PV installation in Hong Kong, comprises of a solar array made up of more than 2,300 PV modules which together has a total area of around 3,180 m2, and a smaller system made up of PV glass laminates.

Each PV module in the solar array is constructed in the form of a rectangular panel and consists of 72 series-connected mono-crystalline silicon PV cells. The panels are mounted on supporting racks in an inclined manner and facing southwards so as to receive maximum solar irradiation during the year.

In addition to these, PV glass laminates are installed on the viewing gallery on the roof of the building. There are totally 20 sets of PV glass laminates, each consisting of 100 series-connected mono-crystalline PV cells sandwiched between two sheets of glass.
