6. Rooftop installation
(interlocking tile, plain tile)
Distribute all roof hooks supplied evenly over the width of the collector
array to spread the loads applied. For this, position the roof hooks as
near to the rafters as possible.

Max. snow load when installing flat-plate collectors on end with an inclination of 30° to 45°
This calculation takes a factor of 0.8 according to DIN 1055-5 into consideration (corresponding to a roof
inclination of 0° to 30°). We recommend roof integration where higher snow loads prevail.
