Find the voltage (V) and current (A) ratings of your panel. These can normally be found on the back of your solar panel system. Check the sunlight conditions are suitable to produce readings on your system. Ideal conditions are bright clear sunlight directly on the panel. Remember safety first when testing your solar panels.
The solar panel should be clean and free from dust. Ensure you do your test in full sunlight without any obstructions. Angle the solar panel towards the sun at the correct pitch. If the weather is bad, redo the test on a clearer day. The panels aren’t the only components you have to test to make sure your system is in good condition.
Detect solar panel quality defects without testing equipment? There are dozens of possible solar panel quality defects that we come across at solar module manufacturers in Asia. Some defects can only be detected by using advanced testing equipment, such as electroluminescence (EL) testers, sun simulators, thermal cameras or resistance testers.
If you encounter an issue with the values during your test, you may want to check the following: The solar panel should be clean and free from dust. Ensure you do your test in full sunlight without any obstructions. Angle the solar panel towards the sun at the correct pitch. If the weather is bad, redo the test on a clearer day.
To do it, turn the knob to the ohms or Ω setting. Once set, connect the probes to the resistor leads and check for the reading. Avoid holding both leads because your skin can affect the result. If the ohms value is between zero and one, your solar panel is functioning well. A measurement of one and above means your solar panel’s cord is broken! 4.
Turning off for cleaning solar panels may affect the testing process. Shutting down the panels can interrupt the flow of energy and impact the accuracy of performance testing. It’s important to carefully schedule panel cleaning to minimize disruptions to the testing process and ensure accurate results.
