A consortium shaped by Germany-based mounting system supplier K2 Techniques and Swiss EPC contractor Solarmotion has deployed a vertical PV system on a bypass highway within the municipality of Teufen within the canton of Appenzell Ausserhoden, Switzerland.
The array is situated on a 75-degree retaining wall and has a capability of 325 kW. It makes use of 756 glass-glass full black photo voltaic modules from an undisclosed supplier.
In line with K2 Techniques, the mounting answer used for the set up is predicated on its “K2 BasicRail” mounting rail mixed with HUS screw anchors. Lichtestein-based Hilti supplied the mechanical dowels for the venture.
Within the system configuration, the PV system’s components, in addition to the K2 constructing safety mat as a substrate, have been anchored on and within the masonry utilizing an adhesive method. The businesses needed to take into account that an anchoring depth of a most of 90 mm couldn’t be exceeded, so as to not have an effect on the statics of the retaining wall.
An engineering workplace from the Swiss highway inspectorate checked all static calculations in the course of the planning section.
The businesses accomplished the venture in two months. Attributable to its proximity to the asphalt, the K2 mounting system remains to be topic to distinctive corrosion necessities and its parts are lined with anodized aluminum for cover. The parts of the fastening system are product of aluminum and A2 chrome steel.
The photovoltaic system is scheduled to be formally inaugurated in December. It’s anticipated that the vertical array will produce good yields, particularly in winter. General, the annual solar energy technology is predicted to be round 230,000 kWh.
The system is injecting energy to the grid of native power supplier St. Gallisch-Appenzellische Kraftwerke AG (SAK) beneath Switzerland’s feed-in tariff regime.
