NOTE
The solar module heats up during operation. Ensure that there is sufficient rear
ventilation to avoid reductions in yield. Also ensure that no flammable gases
can escape or accumulate close by.
In regions with particularly high snowfall, the pressure load calculated in accordance with
the standard based on local snow load information may be significantly exceeded due
to snow overhang or build-up on the solar modules, which could result in above-average
stress on the bottom frame edge. Solarwatt therefore tests its modules above and beyond
the standard IEC 61215 and in accordance with additional standards, taking into account
additional loads in the event of snow overhang or build-up to reflect the actual loads en-
countered in practice and to ensure that our products work safely throughout their entire
service life.
For system documentation, note the positions of the modules and their serial numbers.
Before commissioning, a final inspection of the entire system is mandatory in accordance
with EN 62446 and must be documented.
The following tables show for each installation situation and module type:
•
the way of fastening (screws, clamps, insertion system)
•
the frame areas, approved for fastening
•
the maximum permitted pressure- and suction load on the modules
Information on the tightening torque of the clamping screw can be found in the
documentation of the clamp manufacturer. Fastenings must not deform the solar mo-
dules. Clamps must not touch the front glass. Exceptions to this are the imprints in the
module frame caused by clamps with a pin for potential equalisation.
The module clamps must be completely positioned in the clamping areas shown. If the
module clamps are not all within the clamping area approved for one maximum load, the
lower permitted load applies.
The solar modules can be installed both vertically (portrait) and horizontally (landscape).
