Modules produce the most power when they are pointed directly at the sun. For installations where the Solar 
Modules are attached to a permanent structure, the Modules should be tilted for optimum winter 
performance. As a rule, if the system power production is adequate in winter, it will be satisfactory during the 
rest of the year. The module tilt angle is measured between the solar Modules and the ground. Optimal tilting 
of module is almost the same as the latitude of installation location.

XDISC S.A. recommends using typical aluminium clips designed for framed modules.  

ASOL-250P-WSR module mounting configurations must meet the following requirements: 

-

 

Clearance of 7mm or more between modules is required to allow for thermal expansion.  

-

 

Modules must not be subjected to wind or snow loads in excess of the maximum permissible loads and 
must not be subjected to excessive forces due to thermal expansion of the support structure.
