The premium panels in aleo’s new LEO series are also available as solar roof tiles. With LEO Sol, aleo is launching a high-performance half-cell panel. LEO Sol can be integrated into the roof surface using the Solrif in-roof photovoltaic mounting system from Ernst Schweizer AG. The glass-foil panel with black back sheet is larger and higher-yielding than its predecessors. When mounting with Solrif, the classic roof tile is replaced by the solar roof tile, creating a high-quality and homogenous appearance on the roof.
New efficiency class for proven system
The new monocrystalline premium panel LEO Sol with a size of 1,169 mm x 1,607 mm x 17 mm and a peak output of 345 W consists of 96 half cells. By using half-cells with 10 busbars, aleo minimises the series resistance and thus maximises the efficiency of its LEO premium panel. Instead of 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 panles 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.
Simple planning, comprehensive testing
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.
Solar aesthetics Made in Europe
With its uniform appearance, the solar roof tile Solrif is also suitable for use on listed buildings and for aesthetically demanding new construction and renovation projects. “As the global market leader in in-roof photovoltaic installation, we have particularly high demands on the performance and aesthetics of our solar roof tiles. Together with aleo and LEO Sol, we offer an in-roof PV solution that combines the latest technology with a chic look,” says Helge Hartwig, Sales Manager Solrif at Ernst Schweizer.
Quality as well as sustainability go hand in hand in the production of both system components: The premium panel LEO Sol is produced at aleo in Prenzlau using 100 percent renewable energy and comes with a product and performance guarantee of 25 years. Ernst Schweizer produces the Solrif mounting system with durable aluminium directly in Switzerland. Since the solar roof tile replaces the classic roof tile, both materials and work steps are saved during installation. And thanks to short transport routes within Europe, the LEO Sol-Solrif system combination causes fewer greenhouse emissions during delivery.
William Chen, CEO at aleo: “Our new LEO series is the most powerful that aleo has produced to date. The LEO Sol panel meets the high quality standards of the new series. The black back sheet completes the elegant look of the panel. Together with the Swiss mounting system Solrif, we are bringing a high-quality and sustainable in-roof photovoltaic solution `Made in Europe` to the market that is something to be proud of.”
