cable diameter must be maintained. The
cable must be routed in a way that tensile stress on the conductor
or connections is prevented. The pictures are as below:

The maximum number of series connected modules depends
on the system design, the type of inverter used and environmental
conditions. According to the system voltage (1000V) of the IEC
standard. Under normal conditions, a PV module is likely to experience
conditions that produce more current/voltage than reported at STC.
Accordingly, Isc and Voc must be multiplied by 1.25 (for C-Si or
non-C-Si) we recommend
the maximum number of series connected
modules for each module series as stated below:
