Insurance
Viessmann photovoltaic modules are
tested to be impact-resistant, including
against hail, according to DIN EN 61215,
DIN EN 61730 and EN 61646.
Nevertheless we recommend that the
user insures against extreme weather
conditions and includes the photovoltaic
modules on their building insurance. Our
warranty excludes damage due to such
conditions.
Care, inspection and maintenance
Please observe the service
instructions supplied when clean-
ing or servicing the system.
■ Remove dirt and snow from the pho-
tovoltaic modules. Increased contam-
ination lowers the efficiency of the pho-
tovoltaic system.
■ Have your photovoltaic system serv-
iced regularly to ensure trouble-free,
energy-conscious and environmen-
tally safe operation. We strongly
advise you to arrange an inspection
and maintenance contract with your
local contractor.
