Root.solar Double Seam Panel
Root.solar panels are building integrated photo-
voltaic (BIPV) construction elements which replace
conventional roong and facade materials.
A Root.solar panel has two parts: an overlapping area and
an ‘active PV area’. The overlapping area on top of the panel is
designed to ensure a waterproof connection between the two
adjacent panels on the roof. The overlapping area on the roof
must be a minimum of 200 mm.
Electricity is produced in a thin active photovoltaic layer that covers
the most part of the panel.

1. Installation of Purlins
and Rafters
1.1 Installation of battens which are the most common support
structure in metal roof installations, plays an important role when
installing Root.solar panels. Wooden blanks should be laid on
top of the anti-condensation lm covering the roof base accord-
ing to both the angle of the roof and the snow load.
1.2 Double seam installation is applicable for roof inclination that
exceeds 10 degrees (Fig. 1); the battens should be laid every
250-300 mm, parallel to the rst fastened row (Fig. 2).

1.3 If the snow load is high, battens can be laid more closely
together on the lower side of the roof. However, the cables
of the Root.solar panels must run between the battens,
so the battens must be installed accordingly.
1.4 The junction boxes under each panel must t between two
battens, without touching either (Fig. 3). The junction boxes
are located behind the Root.solar panels, starting from the edge
of the ‘active PV area’ and ending 50 mm below the ‘active PV
area’ edge.

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.

Cutting higher lock is shown accordingly in Figure 5 and 5 a.
Starting from the line where the next Root.solar module comes,
the cut starts continues vertically to module alignment, until the
upper part of the lock reached to an end (Fig. 5 a)
Then, the cut continues parallel to alignment until all upper part
of the lock is cut o.

3. Installation of First Column
Since Root.solar has an active PV area that must
not be bent or folded, the rst column touching the
gable border should consist of regular metal panels.
3.1 After the installation of the rain shadow border, the rst Root.
solar panel should be installed running from right to left, perpen-
dicular to the rain shadow line and parallel to the gable channel.
3.2 The joining edge of the Root.solar panel must be cut from
the locks till the ‘active PV area’ in order to enhance fastening
on the overlap as it was shown in Section ‘Cutting Locks/Edges’
3.3 The bottom of the lowest Root.solar panel that extends
to the eave cannot be cut and folded like a regular metal panel.
The ‘active PV area’ on Root.solar panels provide excellent
water-tightness and prevents metal expansion due to tempera-
ture increase.

3.4 Junction box cables should be in reachable position before
fastening the panels to the battens. The Root.solar panels on the
roof will form electrically one or several series-connected strings
whose ends are connected to the inverter (Fig. 6). Make sure
that the cables are engaged till the very end and ‘clicked’.
3.5 The cable dust caps, which provide protection from mois-
ture and the outside environment, must be removed immedi-
ately prior to making the click connection between the MC4
connectors (Fig. 7).
3.6 After placing the bottom part on the rain gutter, higher lock
(right side) of the rst column will be fastened by using
fastening clamps to the battens. The clamps will be laid in
approximately every 400 mm (Fig. 8).
