Solar panel fault-finding guide including examples and how to inspect and troubleshoot poorly performing solar systems. Common issues include solar cells shaded by dirt, leaves or mould. Check all isolators are all on, and the circuit breakers have not tripped off. Check the grid voltage on the inverter display or app for over-voltage issues.
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.
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. Check the grid voltage on the inverter display or app for over-voltage issues. Hire a solar professional or electrician to inspect the solar system.
Some solar panel quality defects can not be detected without testing equipment, such as electroluminescence (EL) testers, sun simulators, thermal cameras, or resistance testers. However, there are also several defects that can be identified visually.
It’s important to regularly check your solar panels for any signs of damage, such as micro-cracks or broken wires.
Keep in mind that monitoring your electric bill IS NOT a foolproof way to determine if your panels are working. Your solar panels may be working correctly, but your electric bill could still be high if you’re using a lot of electricity. It’s going to depend on how much, if any, of your home is stilled tied to your city’s electrical utility.
