Make sure no other system components impair the
mechanical or electrical function of the solar modules.
• Only work in dry conditions with dry solar modules and dry,
electrical isolated tools.
• Do not drill any holes into the module frame or the glass
surface and do not carrying out any welding work on or in
• the direct vicinity of the solar module.
• To avoid burns do not touch solar modules under load
without wearing gloves.
• Never touch solar modules with cracked or broken cover
glasses or damaged back sheets without wearing gloves.
• Comply with the applicable occupational health and safety
regulations (e.g. regarding protective clothing).
• Carry out the entire installation in the presence of a second
person so that assistance can be provided in case of an
accident.
• Keep a copy of this installation manual in the immediate
vicinity of the system for the whole lifetime of the system.
• Make sure that nobody will kneeling, standing or walking
on the modules and that no other punctual loads happened
to the front- or backside of the solar module. Point loads
can lead to micro cracks, thus risk of yieldloss and potential
electrical hazard will increase.
3. Installation
3.1 General installation instructions
Make sure that all locally applicable standards, construction
regulations and accident prevention regulations are complied
with.
• Select an installation location with the maximum sunlight
at all times of the year. Avoid shaded areas. Shading all year
round of larger areas or single modules or cells is reducing
annual yield and potentially reducing bypass-diodes
lifetime.
• In northern latitudes, orient the solar modules to the south.
• Make sure a minimum module inclination of 5°, otherwise
self cleaning effect will be severely limited, thus parts of
cells can be shaded and will reduce yield significantly.
• Always mount the solar modules with the same orientation
and tilt angle. Otherwise you will have to use a separate
inverter or separate DC input.
• Maintain an adequate distance between adjacent solar
modules to allow for expansion in case of changing thermal
conditions.
