2.2 Requirements
Installation Site
Please note the following guidelines that apply to the installation
site:
■
Solar modules are not explosion-proof and are not suitable for
use in explosive environments.
Do not operate solar modules near highly flammable gas and
vapors (e.g. gas tanks, gas stations).
Do not install modules in enclosed space.
Do not install modules in locations where they may be
submerged in water (e.g. floodplains).
Do not use modules as a substitute for the normal roofing (e.g.
modules are not watertight).
Do not install modules in close proximity to air conditioning
systems.
Do not install modules above 4000 m (13120 ft) altitude above
sea level.
Contact with saline water (e.g. spray water from the sea) and
salt aggregation on the modules must be avoided.
Do not bring any chemical substance (e.g. oil, solvent etc.) into
contact with any part of the panel. Only substances, which are
released by Qcells, are allowed to be used during installation,
operation and maintenance.
Any installation of modules on surfaces of water is prohibited.
This includes installations on floating as well as pile-based
platforms. Qcells may extend the coverage of its warranty to
such installations, based on a case by case assessment of
the system design and location. A prior written consent by the
warrantor is required in any case.
The solar modules are designed for the following applications:
■
Operating temperatures from –40 °C to +85 °C
(–40 °F to +185 °F).
■
Pull loads up to max. 4,000 Pa and push loads up to max.
8,100 Pa (see chapter "Mounting options").
■
Installation using a mounting structure for solar modules.
Prevention of Shadowing Effects
Optimal solar irradiation leads to maximum energy output:
For this reason, install the modules so that they face the sun.
Avoid shadowing (due to objects such as buildings, chimneys
or trees).
Avoid partial shading (for example through overhead lines, dirt,
snow).
Mounting Structure Requirements
The Modules shall be installed and operated on mounting
structures that comply with any applicable laws and stipulations
as well as with the following:
■
Conform to the necessary structural requirements.
■
Compliant with local snow and wind loads.
■
Properly fastened to the ground, the roof, or the façade.
■
Forces acting on the module are relayed to the mounting
substructure.
■
Ensures sufficient rear ventilation of the module.
■
Avoid the usage of different metals to prevent contact
corrosion.
■
Allows for stress-free expansion and contraction due to
temperature fluctuations.
Ensure that no additional forces are applied through the
mounting system into the module except for the wind and snow
loads. Additional forces and moments of torque at the mounting
positions caused by torsions, displacements or vibrations in the
mounting system are not allowed.
Ensure that the clamps and the mounting frame are compatible.
Clamp System Recommendations
Use customary clamps that satisfy the following requirements:
■
Clamp width: ≥ 40 mm.
■
Clamp height compliant with a 32 mm frame height.
■
Clamp depth: 7-12 mm. (applicable for all CL clamping mounting
options at section "2.3 Mounting options")
■
Clamps are not in contact with the front glass.
■
Clamps do not deform the frame.
■
Clamps that satisfy the structural requirements based on the
conditions of the installation site according to the applicable
regulations and technical standards.
■
Long-term stable clamps that securely affix the module to the
mounting frame.
Module Orientation Requirements
■
Vertical or horizontal installation is permitted.
Ensure that rain and melting snow can run off freely. No water
accumulation.
Ensure that the drainage holes in the frame are not covered.
No sealing.
75°
3°
Maintain the permissible angle of inclination.
■
Minimum angle of inclination: 3°
■
Inclination angles above 75° may be limited by
local regulations
Standing water on the modules glass needs to be
avoided.
