While the photovoltaic panels installed on your rooftop may have no moving parts to become worn, much like the roof ties upon which they are mounted, they can sustain damage as the result of local weather conditions. In practice, however, one of the most common explanations for diminished system performance is simply an accumulation of dirt on the glass panels that are designed to protect the PV cells beneath, and it is cleaning rather than professional solar repairs that will be required. Any cells shielded from the sun’s rays will produce no current and the overall output of the system will be correspondingly reduced.
In regions where severe hailstorms may tend to occur, panels could sustain physical damage but, in many areas, the greatest threat comes from the animal world. Birds, especially the large gulls found in coastal areas, will often cause damage to panels, while it is quite common for squirrels and other small rodents to attempt to make their nests beneath the panels. Given that they also have a tendency to chew through any cables that happen to be accessible extensive solar repairs can sometimes be necessary.
Sometimes, even pristine clean and undamaged panels may fail to produce the expected output, even though the wiring and all subsidiary components are fully functional – leaving an owner scratching their head in frustration. Once again, Mother Nature may hold the answer. If your garden contains deciduous trees, they might have caused no problems during the winter months, but once regaining their leaves, they could be blocking the sunlight from your panels. To fix it will not require a solar repair company, but a garden service.
Although PV panels are extremely durable and should, typically, have a life expectancy of at least 25 years, some might occasionally prove faulty or develop micro-cracks that could permit the entry of rainwater and interfere with power generation. They are complex structures and damage to one panel can sometimes affect the entire installation. In those relatively rare cases where solar panels may require actual repairs rather than just cleaning, this is a task that should be left to an expert. The same applies to the installation. Be sure to engage a well-established company, as there are plenty of opportunists out to make a few bucks from this rapidly growing technology.
That said, the most frequent problems with a PV installation tend to be with the attached components rather than the panels. Where these occur, it will most often be the inverter that is not performing as it should. If it displays a red light and a screen error while it is switched on, then you will need a solar specialist to repair or replace it. The inverter plays a pivotal role in the operation of your system, enabling it to distribute power via your domestic circuitry to run your appliances.
The amount of electricity produced by your PV system can be monitored by a generation meter. If your system has one and it displays a red warning light even during bright sunlight, the installation is not producing power. This will require the attention of an expert to track down and fix the underlying cause. Once again, be sure to use a reputable, specialised service provider for all of your solar repairs.
In practice, it pays to be just as particular when sourcing a company to supply and install your system. When dealing with PacB Group, for example, you can be assured of top-quality components backed up by many years of experience in the development and implementation of innovative power generation solutions. Generous warranty conditions, affordable service contracts, and prompt service are guaranteed, whether for expert installations, routine maintenance, or professional solar repairs.
