    Norwegian startup Over Straightforward verified the wind resistance of its vertical PV system for roofs by utilizing computational fluid dynamics (CFD) simulations. The simulations, carried out by the IFI Institut für Industrieaerodynamik GmbH, show that the system doesn’t expertise elevate, even at wind speeds of as much as 47 meters per second.

    Picture: Extra Straightforward

    Norwegian startup Over Straightforward studies the preliminary outcomes of a collection of computational fluid dynamics (CFD) simulations of its vertical bifacial rooftop PV system, which makes use of specifically designed photo voltaic modules.

    The IFI Institut für Industrieaerodynamik GmbH in Germany supported the corporate in measuring the wind resistance of the system.

    “Wind tunnel assessments on a 1:50 mannequin with 360 strain faucets had been carried out in a big boundary layer wind tunnel laboratory at IFI Aachen,” CEO Customs of Trygve Mongstad pv journal. “Exams had been carried out for various heights of the constructing and at completely different angles of assault on the constructing. “

    The German institute proved that the vertical system has no elevate, even with robust winds of as much as 47 meters per second, based on Mongstad.

    “All measurements and analyzes are in accordance with the German Requirements DIN EN 1991-1-4:2010-12, DIN EN 1991-1-4/NA:2010-12 and the wind tunnel testing guideline of the German/Austrian/ Swiss Wind Engineering Affiliation, WtG, in addition to EN 1991-1-4: 2005,” he mentioned. “As well as, they adjust to worldwide codes equivalent to ASCE 7-22 and ASCE 49-21.”

    Simulations confirmed the system may work with out ballast or roof attachment, based on his assertion.

    The corporate at the moment makes use of PERC cells with a bifaciality of 77% to 81% or HJT cells with a bifaciality of 90% in its demonstrators. The PV system, which features a mounting system and photo voltaic panels, is available in a pre-assembled package deal, which makes them straightforward to mount. Every unit measures 1,600 mm x 1,510 mm x 350 mm, weighs 24.5 kg, and has an IP68 enclosure ranking and three.2 mm double tempered glass.

    Over Straightforward plans to work with manufacturing companions in China and Spain to start manufacturing photo voltaic modules. At present, it makes use of photo voltaic cells from undisclosed Asian producers.
