Multiple Panels/Strings in Parallel
Two adjacent panels in parallel (12V systems) 200W
A parallel connection is achieved by joining all of the positive (+) and negative (-) nodes
together. When placing panels in parallel, it is recommended that the voltage levels are
within specification. In other words, the Vmp (maximum power voltage) of the panels must
all be within 10% of each other. Typically, connecting panels in parallel is achieved
through using identical panels. A simple way to place panels/strings in parallel is by using
a branch connector, shown in Figure 5.

Remember to always use the recommended gauge size based on the total array
current. Sizing the cable incorrectly may result in melting wires and/or fire.
