Potential equalization of the solar generator is
prepared in the factory and is recommended. It
can be carried out using the existing grounding
bores on the long sides of the frame in accor-
dance with the valid local regulations.

It is advisable to install lightening protection in exposed locations. The solar modules
should be incorporated in existing lightening protection equipment. For this, take into
account the relevant valid regulations (e.g. EN 62305 and VDE 100).
NOTE
Maintenance and servicing
A photovoltaic system needs practically no
maintenance, as the solar modules are cleaned
by the rain at the recommended minimum ang-
le of 15°. To avoid reductions in yield, we do,
however, recommend carrying out a regular vi-
sual check on the module surfaces. Particularly
heavy soiling (e.g., leaves) can cause shades
which reduce performance and should there-
fore be removed. Clean the glass surface with
water, a water-ethanol- or water-isopropanol
intermixture and a soft nonabrasive cloth only.
In exceptional cases, a conventional cleaning
agent may also be used in the recommended
dose. Do not use aggressive cleaning agents
or metal objects, as they can be particularly
damaging to the hardened glass surface. The
electric cables should (where accessible) be
checked regularly for damage, corrosion, and
firm hold. Pay particular attention to DGUV
regulation 3 and DIN VDE 0105-100.
Disposal
Dispose of defective or old solar modules pro-
perly; they should never be disposed of with
domestic waste. The disposal of solar modules
is regulated in the EU Waste Electrical and
Electronic Equipment Directive (WEEE). Old
solar modules can be mostly returned in usual
commercial quantities to nearby municipal
collection sites and local civic waste collec
-
tion points at no charge. The WEEE Directive
is nationally oriented, meaning that each EU
Member State has its own legal regulations
and practical handling for the sale and return
of PV modules.
Contact us by e-mail at [email protected]
and specify the number and type of modules
to be returned. We will then coordinate all
further details for returning your modules.
