Rust on the circuits and welding of the photovoltaic cells: they are normally due to humidity entering the 
module through breaks in the encapsulation layers occurring during the installation or transportation. 

CONNECTION AND WIRING CONTROLS 

Every six months, check the tightness of terminal screws and the general condition of the wiring. Also, check to 
be sure that mounting hardware is tight. Loose connections will result in damage for array. Do not touch live 
parts of cables and connectors. Use appropriate safety equipment (insulated tools, insulating gloves, etc.), 
when touching them. Cover the front surface of the Module by an opaque or other material when repairing. 
The ASOL-250P-WSR modules when exposed to sunlight generate high voltage and are dangerous.
