The photovoltaic panels have been installed and the bridge is being installed
A bridge crossing the Pò river in San Mauro Torinese, in northern Italy, is set to host a 300m long PV system designed to rely on special mounting structures and full-black modules. . This research evaluates whether the deformations due to temperature load on bridges can be minimised by incorporating photovoltaic solar panels on the bridge surface. The panels can be attached to the bridge truss, piers, and the periphery of the deck excluding the pavement, i., excluding bridge superstructure elements under direct traffic load to avoid wear and tear of the solar panels. The local administration said the bridge was chosen as the rooftops and surfaces available are all located in. . Weather-conscious equipment selection and design for photovoltaic (PV) systems can result in a longer PV lifetime and improved system durability. Since the 2016 edition of NFPA 1, access pathways have been required on roofs to facilitate fire service access as well as egress. .
