2. Cutting Locks / Edges:
Depending on the length of the roof, the distance of the overlap
(the point where one Root.solar panel joins another) may vary.
The overlapping area must be a minimum of 200 mm. Due to
thermal expansion, subsequent Root.solar panels which extend
to the overlapping area should be 3 mm away from the previ-
ous panel.
2.1 Cutting higher lock is shown accordingly in Figure 4, 4 a and
4 b. Starting from line where the Root.solar module overlaps with
the next one, the cut should start from outside of the lock with
the angle of approximately 30 degrees as it is shown in Figure 4 a,
till it reaches the edge. Then, the cut continues perpendicular to
module alignment until it reaches the end of upper part of the
lock. After that, the cut continues till the upper part of the lock is
completely cut out as it is shown in Figure 4 b.
