4.6.1 Low Slope Surfaces
Low slope surfaces present special cases in terms of setting
up flat roof holders.
If the collectors are to be installed on low slope surfaces
(roof slope angle in relation to horizontal = ) using flat
roof holders, a flat roof holder installation angle (= ) of a
maximum of 20° is permitted. The overall slope of the
collector in relation to horizontal may not exceed 60°.
