Abstract/Summary:


The Photovoltaic Laboratory (PV LAB) at Bern University of Applied Sciences BFH in Burgdorf, Switzerland, developed its own remotely-controlled IR Multicopter Drone. The aim was to economically optimise the quality-control of predicted energy yields from PV-installations in the Swiss PV monitoring network as operated by the PV LAB since the 1990s. The work is carried out within the SCCER FURIES project and in collaboration with Swiss industry partners. The drone system was assembled in a Bachelor thesis and extensively tested on the PV LABs own roof-top PV-installation. Application to two large Swiss PV-installations (football stadium “Stade de Suisse“, Bern / 1.3 MWp and open-field “Mont Soleil” in the Jura Mountains / 554.5 kWp) confirmed the economic benefit of remotely-controlled drone inspection as compared to manual thermographic examination. The IR Multicopter Drone now allows a rapid thermal survey of operating PV-modules at all installations in the Swiss PV monitoring network. As the system is electric, it offers an added value for thermal inspection of PV-installations where no disturbing emissions are allowed. This is a requirement at the world’s highest research facility at Jungfraujoch (3 454 m asl) where the PV LAB measures the longest energy yield record from PV in the Swiss Alps.
