A second solar panel can be connected in parallel with the panel provided in the kit to increase the current
output at the same output voltage. Fig. 3.4 above shows the arrangement for connecting the second solar
panel in parallel using the Solar Panel Connecting Wire Kit Model SCW-20-2 supplied with this kit, and MC4
Branch Connector Kit (SBC-2), sold separately. This arrangement is applicable if the two solar panels are to be
connected in parallel and are mounted adjacent to each other.
The output wires of the two solar panels are first connected in parallel using the MC4 Male and Female Branch
Connectors. The outputs of the Branch Connectors are then connected to the SCW-20-2 wires for connecting to
the external PV circuit.
