Soltech Energy, a Swedish PV system integrator and solar product supplier, is building several PV facades in its home market. It recently installed a 646.6 kW solar facade on a newly built garage with 300 EV\u2013charging posts in Gothenburg, Sweden, by adopting a special design it has developed for buildings with particular airflow patterns.<\/p>\n\n\n\n

The flow of air in the garage is important because of exhaust from the vehicles. The facade is open so the air exchange does not need to be measured, as it is far beyond the required levels for garages, according to the company. It also claims that the air flow is beneficial for the temperature of the panels.<\/p>\n\n\n\n

\u201cThe facade is being built with semi-transparent modules that requires a certain tilt angle and, at the same time, it is placed on a building wall that needs a high exchange of airflow between its inner and outer parts,\u201d the company\u2019s chief innovation officer, Anna Svensson, told pv magazine<\/strong>.<\/p>\n\n\n\n

\u201cFor these reasons, we decided to use a prefabricated, 11-meter hot-dipped galvanized steel construction built by our unit Fasadsystem, which allows the deployment of the panels with the required tilt angle before the structure is attached to the wall, and also the necessary air passages for the garage walls through interstices present between the horizontal rows of panels.\u201c<\/p>\n\n\n\n
