The new monocrystalline panel Leo Sol with a size of 1,169 mm x 1,607 mm x 17 mm and a peak output of 345 watts consists of 96 half cells. By using half-cells with 10 busbars, Aleo minimises the series resistance and thus maximises the efficiency of its solar panel. Instead of a flat wire, thin, round wires are used so that more light hits the cells. The division of the cells and the closely spaced busbars also ensure that the panels last longer, as additional current paths are created.
With the Solrif in-roof PV mounting system from Ernst Schweizer, which has been tried and tested for over 20 years, Leo Sol is laid overlapping and tension-free on the pitched roof instead of being clamped. The solar roof tile is laid directly on the supporting battens just like conventional clay roof tiles. In addition to partial roofs, full roof coverings are also possible: Solrif blind modules offer design options for integrating corners and edges around chimneys, skylights or dormers homogeneously into the roof. Due to the free lower edge of the panels, the Solrif system is self-cleaning and requires virtually no maintenance.

The planning software Solar.Pro.Tool from Schweizer allows the system configuration with Leo Sol to be planned easily and, taking into account statics and electrics, safely. Leo Sol has been tested and certified as a hard roofing system for fire protection, is free of snail tracks and can withstand hailstones of up to 40 mm. (mfo)
