Electrical Connections
The connectors used in these panels allows for modules to be connected in series or parallel. However, connecting the panels in this manner can put the by-pass diode in
the panel and the battery at risk for damage and could create a safety issue. Please read the DANGER! note below.
Series Connection
Connecting the panels in series increases the voltage of the system, so the two panels produce double the voltage as compared to one panel. This high voltage
can cause damage to the battery and could cause a safety issues. Please read the DANGER! note below.
To connect panels in series, connect the negative (-) plug of panel #1 to the positive (+) plug of the panel #2. See Figure1 left.
Parallel Connection
Connecting the panels in parallel increases the current of the system, so the two panels produce double the current as compared to one panel. This high current
may cause damage to the battery and the by-pass diode in the junction box and cause a safety issue. Please read the DANGER! note below.
To connect panels in parallel, connect the positive (+) plug of panel #1 to the positive (+) plug panel #2 Connect the negative (-) plug of panel #1 to the negative (-)
plug of panel #2. See Figure 1 Right. In this configuration, cable adapters will be needed.

. Electrical parameters are measured at Standard Test Conditions (STC).
The series fuse must have an interrupting rating that is equal to or greater than the maximum fault current that the fuse is required to interrupt, including contributions from all
connected sources of energy.
DANGER!
Connecting panels in series will double the voltage output of the panels, reaching voltages as high as > 40V. If attached to a low voltage
battery, e.g. a 12V battery, this high voltage could cause damage to the battery and could cause a safety issue. Please check the charging
characteristics of the battery in use.
Connecting panels in parallel will double the current output of the panels, reaching currents as high as > 12amps. If attached to a battery for
charging, this high current may cause damage to the battery and cause a safety issue. Please check the charging characteristics of the battery
in use. Additionally, if one of the panels were to go into reverse bias, for example by shading, damage to the by-pass diode in the junction box
may occur. Avoid shading either panels. SunPower does not recommend connecting these panels in parallel if shading will occur.
