Power yields of an alpine photovoltaic pilot plant

Solar power in the Alps during winter months

At a glance


With the photovoltaic test facility in Davos-Totalp, the influence of the alpine region (altitude, snow cover of the surrounding area, snow cover of the modules, etc.) on the photovoltaic yield in the mountains is being investigated. During the several years of operation, different configurations (module technology, framed/unframed modules, tilt, etc.) on the yield situation over the day (focus on marginal hours) and over the course of the year (focus on winter electricity share) are investigated and documented every six months.
