Firstly, you need to remove the solar panels safely to fix a roof leak under the solar panels. Inspect the area for damage or loose fittings. Replace or repair any damaged components, such as flashing or seals. Make sure the solar panels are properly reinstalled and apply a waterproof sealant. Finally, conduct a thorough leak test.

Check the solar system performance data on the app and website, if available. Check the solar panels for dirt, leaves, mould, or shade issues.
If you notice that your solar panel is not producing as much energy as it used to, it could be a sign that something is wrong. Another sign to look out for is physical damage to the panel, such as cracks or scratches. In some cases, a bad solar panel may also cause your inverter to display an error message.
Check the solar system performance data on the app and website, if available. Check the solar panels for dirt, leaves, mould, or shade issues. Check the solar inverter for any warnings or faults. Check that the isolators are all on and that the circuit breakers have not tripped off.
To determine whether your system has solar panel cracks, look for hairline fissures under the angled light, and check for slight discoloration and a white, web-like snail trail pattern. Even if you buy the perfect solar panel and place it on a suitable roof, you are not immune to solar panels breaking.
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.
The test signal amplitude is kept below a few volts, so the testing principle is very gentle on the solar cells. At low frequencies below 5-10 kHz, we normally do not measure any noteworthy impedance in fully illuminated solar PV panels, and the series resistance of the string dominates the spectrum.
