About SL Rack
SL Rack GmbH, based in Haag in Upper Bavaria, develops and markets photovoltaic mounting systems (substructures) for pitched roofs, flat roofs, ground-mounted installations, façades, carports and agri-PV. The products are tailored specifically to the needs of installers and include, among other things, roof hooks, trapezoidal and RAIL systems, module clamps, roof replacement panels, steel and plastic hammering profiles, purlin and rafter systems, and complete system solutions such as SL Fast Flat, Flat Roof Generation 2.0, SL Energy Wall and the SL Tracker. Installation is carried out using a modular system of just five components; few pre-assembled parts minimise storage and logistics costs. Materials are steel and a special plastic. Planning services include the SL Planner and Solar.Pro.Tool tools as well as training via the SL Rack Academy with webinars and hands-on training sessions.
