SERIES AND PARALLEL CONNECTIONS
SERIES CONNECTIONS
Connecting two identical Panels (of the same wattage) in series will multiply
the system voltage by 2 and keep the output current at the same level. Series
connections can be made by connecting the positive connector of one Panel
to the negative of the next
