Collector protection
against
lightning, hail, frost, overheating
Must be performed by an autho-
rized service technician/service
shop for such operations.
Our warranty does not cover dam-
age from extremely strong acts of
nature. We recommend that dam-
age of collectors be included as a
clause in your building insurance.
•
Collector protection against
lightning
. The lightning rod should be 1.5
meter
higher and 3 m
eter
far away from
the solar collectors.
•
Collector protection against hail,
strong wind and snow mass
.
Each solar
collector is
tested for resistance to harsh
weather conditions:
- Hail resistance: size up to
25 mm
/1”
when collector mounting angle is ≥40°.
In areas with frequent hailstorms it is
recommended to install a protective net
over collectors.
- Strong wind resistance: wind speed up
to 120
km/h
In areas with strong, steady winds it is
recommended to further strengthen the
collector support fixation to the building
structure, as well as frequent inspection
to prevent any loosening of connections.
- Snow mass resistance: load up to
30 cm
– 1.25 kN/m
