The best, quickest, and easiest way to test a solar module is to check both the open circuit voltage (Voc) and short circuit current (Isc). Depending on the reason for testing; the test can be done: at the controller; at the combiner box (if …
The Isc Test should be done on the module or string level, as the currents should be kept to 10A or less. The test should be done on a sunny day, and the measured value should be linear with the sunlight conditions available. An insolation or solar radiation meter can be very helpful in determining the sunlight conditions.
A couple of simple measurements are a great way to quickly troubleshoot and isolate possible problems in a solar array. Testing PV Modules is efficiently done by checking both the open circuit voltage (Voc) and short circuit current (Isc) in full sunlight conditions.
To perform the Voc Test, simply measure the voltage between the positive and negative terminals. This voltage should be within ~10% of the rating on the data sheet under most sunlight conditions. Sign: A negative voltage number would indicate a reverse polarity of the wiring.
Therefore, values from either the Standard Test Conditions (STC) table, or Nominal Operating Cell Temperature (NOCT) table should work. To perform the Voc Test, simply measure the voltage between the positive and negative terminals. This voltage should be within ~10% of the rating on the data sheet under most sunlight conditions.
Solution: Confirm diode orientation or replace diode in module. If accessible, you will need to remove the Junction Box cover on the back of the solar module. Sign: A voltage number that is lower than the expected value. Cause: Check any wiring, if present, to make sure there are no wiring mistakes or bad connections.
