Attach the second Pyranometer to your array. The sensor should be attached so top
of the sensor is in the same plane as the PV panels. The sensor comes pre-attached
to a bracket for easy installation.
Attach the PV panel temperature sensor so it registers the temperature on the
backside of a PV panel. See
mounting considerations.
Connect the sensor(s) to the proper location on the circuit board. Connect the
Pyranometer cable to terminals Pyranometer #2 and GND. Connect the PV Panel
temperature sensor cable to the two terminals labeled PV Temp #1.
