Strings of solar panels operate at high voltages, up to 600V or higher. Operating at these elevated voltages over many years can, in some cases, allow a current leak to develop through the cells to the aluminium frames of the solar panels and into the earth, resulting in a significant performance loss.
Here are some common reasons your solar panels might be underperforming: The Dirt: Just as plants need clean leaves to photosynthesize effectively, your solar panels need clear surfaces to catch the sun’s rays. Dirt, dust, leaves, or even bird droppings acting like a layer of shade could be the culprit.
Loose connectors and improperly seated terminals can cause low voltage or current output. Junction boxes should be checked for tight screws or properly crimped connections. Rare manufacturing defects may require panel replacement. Micro cracks in solar panels can lead to power loss over time.
This could be caused by a lightning strike or power cut which has tripped the solar circuit trip switch. "The first port of call should be checking the distribution board or consumer unit to ensure that the solar circuit's trip switch is in the 'up' position. If not, pushing the trip switch up will resolve it," Mr Robinson explains.
The most common cause of low power output in solar panels is obstructions or shadows on the array. Checking Voc (voltage open circuit) and Isc (current short circuit) measurements can help diagnose panel issues. Loose connectors and improperly seated terminals can cause low voltage or current output.
Blown bypass diodes - Permanent failure often due to severe localised shading or overheating. Earth leakage is a common problem with older solar panels that is often caused by backsheet failure leading to water ingress or PID or potential induced degradation. Strings of solar panels operate at high voltages, up to 600V or higher.
