Five adjacent panels in parallel (12V systems)500W
Five solar panels is the maximum amount of panels that can be connected in parallel if they 
are adjacent to one another, without using extra cabling. Fig. 9 above shows the arrangement 
for connecting five solar panels in parallel. Remember that this arrangement is applicable if 
the five solar panels are to be mounted adjacent to one another. This connection requires four 
(4) pairs of MC4 Y- Branch Connectors. When one or multiple panels are mounted at 
different locations- that is, separated by a distance, the panels need to be extended with MC4 
Extension Cables (sold separately).
