PANEL TEST PROCESS (FOLLOWING)
CURRENT TEST IN SHORT-CIRCUIT
This test must be done with important irradiance conditions. The values displayed by a cloudy and grey weather
are thus irrelevant.
Set the multimeter on the A DC (continuous current) range corresponding to the panel intensity.
•
Connect the red cable to the « A
» port (intensity) and the black to the “COM” port (common).
•
Connect the cables
to the panel’s connectors (red –
red, black
–
black).
•
Place the solar panel perpendicular to the sun.
Result:
The displayed value must be equivalent (+/-20%) to the intensity in short circuit (Isc) of the panel. This value
can change according to the position to the sun.
You can find the Isc value in the technical specifications of this manual and in the back of each panel.
This test is valid if the displayed values match with the intensity of the panel (+/-20%).
