Mount SolSensor
Attach SolSensor to a PV module frame using the provided bar clamp. It must face in the
same direction as the PV module itself.
Remove the black rubber cover (like a lens cap) that protects the irradiance sensor (the
small white disc). Never touch this disc, it is a highly sensitive optical instrument.
If there is dirt anywhere on the top or sides of the small white irradiance sensor disc, hold
the body of SolSensor in your hand, rotate it so the irradiance sensor facing downward,
spray up at the irradiance sensor with purified water, and let the water carry the dirt
downwards, away from the irradiance sensor. Then use the special microfiber cloth to
wipe away the excess moisture. A spray bottle of purified water and a microfiber cloth
are provided in the SolSensor gear pouch.
Attach SolSensor thermocouple
You will need to use a thermocouple on the backside of the PV module even if you are
using the SmartTemp temperature measurement method.
Unwind the thermocouple and straighten the lead. Avoid kinking the lead.
Insert its yellow plug in the T1 socket at the end of SolSensor.
Straighten the last few inches of the thermocouple lead. The tiny ball at the end is where
temperature is measured.
Place the last few inches of the thermocouple wire against the back of the PV module.
Choose a location that is away from the cooler outer edges of the array.
Apply the green disc of high temperature tape to the tip of the thermocouple. Role your
thumb over the disc to work out any wrinkles. The tip should be near the center of the
disc and in firm contact with the back of the module. Do not use ordinary electrical tape
or duct tape, because these will sag with the heat of the module and allow the tip of the
thermocouple to pull away from the backside of the module. This causes large
temperature errors.
Turn on the I-V Measurement Unit, and connect wirelessly to your PC
Press and release the pushbutton LED.
When the PVA-1000S or PVA-600+ connects to the wireless USB adapter plugged into
your PC, the Status indicator in the upper right corner of the PVA software displays
Ready.
The PVA-1500xx creates a Wi-Fi hotspot. Find and connect to that hotspot in the
network list of your PC.
