4. Maintenance
Solar plants have to be maintained in regular intervals (at least once a year), to ensure an optimal
functioning and to meet the warranty requirements. At least once a year a visual inspection of the
profiles and fixing materials regarding damage or corrosion should be carried out and also a random
inspection of the connection points (screws, nuts) should be performed.
Especially after heavy weather occurrences like storms there should be additional inspections with
special emphasis on the exposed or outer areas of the project site where wind influences can cause
damages.
Damaged parts of the system have to be repaired or replaced. Loose screw connections have to be
tightened again using the torque information given in this manual (§1.3).
In case of polluted modules, we recommend to clean them for optimal performance. Module cleaning
should be performed by professional companies following the manufacturer’s instructions.
In case of major damages to the mounting system or to electrical parts, be advised to contact a
professional company. We point out that there are risks to health and life performing this work.
5. Surface treatment and corrosion
Oberhauser mounting systems are made of aluminium and/or galvanized steel. Depending on the
project location, the atmospheric conditions may vary.
The surface treatment also depends on the chemical characteristics of the soil. These must be provided
by the client by means of appropriate expert opinions when the contract is awarded.
The company Oberhauser Bau - Systeme GmbH certifies surface lifetime of 25 years within the scope
of and in accordance with all general terms and conditions of Oberhauser Bau - Systeme GmbH and
the following conditions.
1. The scope of the surface guarantee is limited, at our discretion, to the assumption of the costs
of repairing the defective profiles or the delivery of defect-free profiles at our expense to the
customer's place of business so that the customer can replace the defective profiles himself.
These must be profiles with the same or higher properties and of the same type.
2. The surface guarantee does not apply to transport damage or damage to the profiles during
installation. Profiles that are driven into the ground must be re-galvanised by the customer or
the appointed installation company. Post-zinc coating cannot be compared with a zinc coating
produced by the factory and must therefore be checked regularly and reworked if necessary.
3. The guarantee cannot be transferred to third parties
4. The surface guarantee is valid for 25 years for installations in areas with normal atmospheric
conditions with regard to corrosion (corrosion classes C1 to C3 according to EN ISO 12944-2).
Systems in more aggressive environments C4 - CX must be considered separately. Additional
corrosion protection is recommended in this case.
5. The surface guarantee does not apply to areas with heavily polluted air or closer than 2 km
from the sea coast and/or to areas where the installations frequently come into contact with
fresh or salt water.
