6 Frequently Asked Questions about “How to diagnose whether the solar panel is normal”

How do I know if my solar system is working?

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.

How do I know if my solar panel is bad?

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.

What should I do if I don't have solar system monitoring?

If you do not have solar system monitoring installed, the first step is to check for any obvious issues with the solar panels, such as a build-up of dirt, dust, mould, or leaves. Maybe a good wash with a soft broom and water is all that they need. Also, check no nearby trees have grown significantly and are shading the panels.

How do I know if my solar panels are generating enough energy?

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.

What should I do if my solar panel is not working?

Before picking up the phone to call for solar panel maintenance (“Hello, my solar panels are not working…”) you can perform a few quick checks to further diagnose the issue: See if a circuit breaker tripped on your electrical panel. Restart your inverter, as this can sometimes clear out any faults in the system.

How do I know if my solar system is leaking?

Unfortunately, it is very difficult to detect an earth leakage without specialised equipment, and often, even a trained solar professional can have trouble diagnosing an earth fault. Check the solar system performance data on the app and website, if available. Check the solar panels for dirt, leaves, mould, or shade issues.
