Liability
Since observance of these installation instructions and the conditions and methods of installation, operation,
use and maintenance of the Suntub® mounting system is not checked or monitored by SolarWorld AG,
SolarWorld AG accepts no liability for damage arising through improper use or incorrect installation, operation,
use or maintenance. Moreover, SolarWorld® assumes no liability when SolarWorld®, its representatives or vicar-
ious agents are accused of gross negligence or intent. The previous restrictions do not apply to damage relating
to death, body or health, as well as in cases applicable to other laws, such as the liability for assumption of
guarantee, liability according to the German Product Liability Act (Produkthaftungsgesetz) or in the case of
infringements of important contractual obligations (cardinal obligations).
Regardless of the previously described limitations of liability, SolarWorld® assumes no liability for infringe-
ments of patent law or of third party rights arising from the use of the modules and the mounting system,
as is present under the regulations previously described.
The text and figures in this manual are in compliance with the state of technology at the time of printing
and are subject to change.
The warranty period is based solely on the usability of the Suntub® itself, and only on that component;
no liability is accepted for loss of yield or for assembly and disassembly costs in case of damage.
Maintenance/Cleaning/Liability
D
The installation company is responsible for ensuring professional grounding of the system and components.
No External lightning protection
A ground is recommended, and often required by local code, for PV-module frames and mounting racks.
Connect all electricity conducting parts with measures suited to this purpose and connect with the earth
(ground) circuit connector (PAS) with at least mm² (copper).
External lightning protection
PV-Module frame and mounting frame must be included in the protection against the direct strike of
lightning. If necessary, consult a lighting protection expert.

Grounding
Maintenance and cleaning
It is generally not necessary to clean the modules (rainfall will have a self-cleaning effect).
In case of heavy contamination (capacity reduction), we recommend cleaning the modules using plenty
of water (from a hose) without cleaning agents, along with a gentle cleaning brush or sponge. Dirt
must never be scraped or rubbed away when the modules are dry as this may cause micro-scratches,
which have a negative effect on the module performance
The generator field should be inspected at regular intervals for flawless condition (visual inspection).
The modules and the Suntub® must be inspected annually for correct position and secure mounting!
