6 FAQs about [What to do if there are spots on the photovoltaic panels]

How to detect hot spots in solar panels?

You can detect an emerging hot spot with an infrared camera only. Eventually, hot spots in solar panels become visible to the eye: the problematic cell becomes brownish. Hot spots lead to a faster solar panel degradation and can even start a fire on your roof. To avoid that, clean your panels from dirt every now and then.

What causes hot spots on solar panels?

Hot spots, one of the most common issues with solar systems, occur when areas on a solar panel become overloaded and reach high temperatures relative to the rest of the panel. When current flows through solar cells, any resistance within the cells converts this current into heat losses.

What should I do if I have problems with my solar panels?

If you encounter problems with your solar panels, contact the professionals to examine and resolve the issues. Keep in mind that this comes at a cost, so it's a good idea to shop around for value.

How do you clean a solar panel?

Any mould or lichen growth should be removed using water and a soft brush. To reduce the adverse effects of dirty solar panels, it is recommended that panels be thoroughly cleaned at least once a year or more frequently in dusty environments. Cleaning solar panels should be done using only water and a soft broom.

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 panel is bad?

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.
