4.2

 

Installing the module 

Make sure that the installation is carried out safely. 

Protect  yourself  and  other  persons  from  falling,  do  not  carry  out  the  installation  in  heavy  winds  and 

eliminate  the  risk  of  falling  objects  as  much  as  possible.  Secure  the  work  area  in  order  to  avoid  the 

endangerment or injury of persons. 

In order not to exceed the max. System voltage at -10 °C, the MBF-GG60 and MBA-GG60 modules must not 

be connected in series with more than 22 modules. 

Additionally, the requirements of the inverters must be observed. In any case, specific checking have to be 

done by the designer, considering the modules working temperatures.  

4.3

 

Observe the allowable maximum mechanical loading: 

Do not exceed the maximum mechanical loading and avoid local pressure. Make sure to consider location-

specific  loads  such  as  wind  or  snow.  Remember  that  the  module  might  sag  when  loaded  under  certain 

circumstances.  In  order  to  avoid  damaging  the  module  by  pointed  or  uneven  structures,  do  not  place 

fasteners or cable ties between the rear of the module and the cross section. 

 

4.4

 

Make sure that the surroundings are suitable: 

Make  sure  that  after  installation  the  module  is  neither  subjected  to  artificially  concentrated  sunlight, 

immersed in water or continuously splashed with liquids. By all means make sure that the module is not 

subjected  to  abnormal chemical  exposure.  Exposing  the  module  to  extreme  levels  of  salt  or sulphur  may 

lead to corrosion

 

4.5

 

The correct location for installation: 

 Beside  the  module  itself,  the  mounting  system  must  also  be  suited  to  the  expected  conditions  at  the 

location of installation (snow, wind) and withstand them easily. The bottom side of the module frame (if 

present)  features  holes  for  draining  precipitation  water.  Make  sure  during  installation  that  these  holes 

retain their function. For portrait mounting, the junction box may be mounted facing up or down on the 

underside of the module but it’s preferable to be mounted facing upwards on the underside of the module. 

 

4.6

 

Yield maintenance through optimal alignment and inclination: 

We advise you to familiarize yourself with the appropriate alignment and inclination of the modules prior 

to  installation  in  order  to  ensure  an  optimal  system  yield.  The  ideal  conditions  for  the  generation  of 

electricity are accomplished when the sun rays reach the generator surface perpendicularly. For modules 

connected in a series, make sure that all modules have the same alignment and inclination in order to avoid 

performance losses.
