As the solar panels are exposed to the environment, various foreign objects such as dust, leaves, bird droppings and other materials can accumulate on the panel surface, reducing the electricity production. As such, the accumulation of dirt on the solar panels should be removed to ensure optimal power generation.
From a safe distance, it may be possible to detect obvious signs of dirt, cracks or foreign objects on the panels. However, it is not recommended to climb on the roof to inspect the panels. Instead, it is advisable to schedule roof cleaning in accordance with the roof inclination, local environment, rain exposure and the manufacturer’s recommendations.
Some solar PV generators may require minimal cleaning efforts whereas others may benefit from regular cleaning. In either case, it is important to ensure that the removal of dirt does not damage the panels. In addition, roof cleaning should be performed by qualified solar PV professionals if the roof access presents a fall hazard.
It is also essential to inspect the panels for physical damage such as glass breakage, exposed equipment or damaged frames. In the event of any irregularity, it may be necessary to contact a solar panel specialist rather than attempting to remove the foreign objects or cracks.
Checking Inverter Performance and System Output
The inverter is often the central part of a solar PV generator. It enables the conversion of electricity generated by the solar panels into a voltage that can be used by the home or redirected to the grid. As such, a defective inverter can result in reduced electricity production or total power loss.
Depending on the brand and equipment, the inverter can warn of potential issues within lights or messages on the inverter or monitoring software. As such, inverter maintenance is essential to detect minor irregularities before they cause system failures. During the maintenance, the service provider can inspect the status of the inverter, investigate any warning signs and verify the performance of the generator in accordance with historical electricity production. For the latter, it may also be necessary to consult the monitoring application, if available. While at it, the professional can also recommend further actions depending on the findings.
If possible, it is advisable to document the findings on the monitoring software and the approximate timing of the warning signs. This can facilitate the identification of the root causes during the inspection. Nonetheless, it is important to leave the electrical cabinet closed and do not attempt to inspect the inverter internally. Rather, it is advisable to rely on professional solar PV service providers to identify and resolve electrical concerns. In particular, inverter maintenance can be scheduled in accordance with the manufacturer’s recommendations to ensure the continued operation of the solar PV generator.
Identifying Wiring and Electrical Faults
Various electrical components, connections, protection devices, and other equipment are necessary for the proper operation of a solar PV generator. As such, exposed wires, damaged cable insulation, faulty protection equipment or other irregularities can also impede electricity production and should be addressed as soon as possible.
Similarly to other equipment, electrical faults can present a wide range of warning signs, including random power loss, inverter concerns or warning messages.
