Abstract: The world’s first solar ski lift has a 60 kW PV system that is tracked in one axis. The robust design of the mechanical system requires less material than usual: less than 100kg of steel per kW nominal PV module. To achieve this goal the steel cables function as the support structure for the PV modules. Generally, it is assumed that the electricity production of solar tracking systems increases by about 30% compared to non-tracked installations. The yield achieved by the solar ski lift is 78% higher than the yield of a fixed plant in the same region for an average January. This is attributed to the fact that the panels are not covered by snow and to the high reflectance values of the snow cover of the surroundings, especially in the morning and evening. In the following months this high value decreases and, as the snow melts, it reaches around 34%. It is possible to obtain high yields PV even in the winter in the Alps. Commonly obtaining high PV-yields in a region like the Alps, is known to be a systemic problem of PV in snowy region, but can be overcome by a tracking-system.
