Recent studies have revealed that a dirty solar panel can lose up to 50% of its efficiency when compared to a clean one. A study conducted by the U. S. National Renewable Energy Laboratory (NREL) found that solar panels that are properly maintained can work 3.5% more efficiently.
In the US, panels can lose around 30% of their efficiency if they are not cleaned regularly. The location of the solar panels will determine the amount of dirt that accumulates and the ease of cleaning them. Most solar system warranties do not require or specify that you clean the panels regularly to maintain the warranty. However, you will get much more benefit from this than from spending time or money on cleaning solar panels.
While DIY methods and professional services can help keep your panels clean and in good condition, the solar industry is also constantly coming up with new ideas for easier maintenance. Dust and dirt will settle on the panels and then be blown away or washed away by the wind, without you having to lift a finger or worry about the efficiency of the solar panels.In most parts of Australia, even in some dry areas such as Adelaide, solar panels are naturally cleaned by plenty of sun, rain and wind. The combination of cicada rain (from sap), pollen and dust has been reported to cause hard debris to form on solar panels, which is very difficult to remove. The Clean Energy Regulator recommends that solar panel systems only be inspected and maintained by an authorized electrician or solar panel system installer accredited by the Clean Energy Council. Some of this black dust will settle on rooftop solar panels, but for the most part it will be blown away or washed away by the climate before it becomes a problem.
Cleaning the solar panels of a home in Brisbane requires a clean sponge and a mild detergent to effectively remove dirt. Most solar panel cleaning professionals are not qualified to perform an official inspection, but they should be able to detect any obvious problems for you. While many homeowners want to keep their costs down and prefer to do it themselves, solar panel cleaning services offer professional service and follow industry safety protocols. If there are a lot of tree branches near the roof, the wind can blow pollen, flowers, leaves and other debris onto the solar panels. It is clear that keeping solar panels clean is essential for optimal energy production.
Regular maintenance is necessary to ensure that your system is running at its best and producing as much energy as possible. Cleaning your solar panels regularly will help you get more out of your investment in renewable energy.
