Solar cells are wired together and installed on top of a substrate like metal or glass to create solar panels, which are installed in groups to form a solar power system to produce the energy for a home. A typical residential solar panel with 60 cells combined might produce anywhere from 220 to over 400 watts of power. Depending on factors like …
In direct sunlight, you should see a voltage close to the Voc rating. For example, a monocrystalline panel typically shows 20-40 volts, while a polycrystalline panel might be closer to the lower end of that range. Next, you’ll want to test the current (amps) your panel is producing. Set your multimeter to measure amps (current).
Follow these steps to test your solar panel: Turn off the solar panel system to ensure your safety. Set the multimeter to measure DC voltage. Connect the positive and negative leads of the multimeter to the corresponding terminals of the solar panel. Place the solar panel in direct sunlight and take a reading of the voltage output.
Nevertheless, individual panels can fail faster than that. If you can do so safely, check the panels occasionally for any obvious signs of problems; for example, discoloured areas on the solar cells (usually a 'hot spot', where the panel overheated and was damaged).

The installer should supply the instructions to you, but you can always look them up on the manufacturer's website. A simple way to check on the health of your system is to look at the colour of the lights shining on the box on a sunny day, when the system should be busily generating solar power.
To determine if your solar panels are generating sufficient energy, there are several key indicators you can rely on. Electric Bills: Regularly monitor your electricity bills to observe any significant decrease in your energy expenses, indicating that your solar panels are effectively offsetting your electricity usage.
As you can see this defect can be easily spotted by performing a visual inspection. Also, the problem is visible during an EL test. Your quality inspection person on-site can trace the exact cause and correct it for future shipments. Below is an example of a broken/ chipped solar cell:
