Solar Panel Cleaning
Photovoltaic panels are constantly exposed to various types of weather and are thus a target for dirt, dust, industrial residues, atmospheric pollution, algae, moss, bird droppings, etc. Chemicals used by un-professionals to clean solar panels are also responsible for the deterioration of the surfaces. These form an excellent attraction for dirt and accelerate the deterioration process, with negative repercussions on the appearance and, above all, the function of the structure. The presence of these elements on the panel’s surface prevents the sun’s rays from filtering onto the panel’s photovoltaic cells completely, reducing the solar performance and, therefore, efficiency.
We do not use any chemicals! We only use purified water when cleaning solar panels.
Accumulated dirt residue reduces efficiency and may damage the material the panels are made from. Cleaning is, therefore, an indispensable part of the maintenance of these structures, and the frequency of the cleaning depends on the geographic area and climate. Industrial areas may require more thorough maintenance than rural areas.
An important part of having a trained professional do the job is that they can check other aspects that can affect the health and performance of your solar system. These include potential fire safety issues, cracks, hot spots, and nests from uninvited guests like birds.
Another reason to go professional is safety: Getting on your roof can be a dangerous business, especially without proper safety gear. Without the right equipment and experience, you could put yourself at risk or potentially injure yourself.
How often should I clean my solar panels?
As you can see from the pictures, solar panels get dirty quickly. We recommend cleaning solar panels at least two times a year - usually in March and September since the winter has too much rain for a cleaning to last, and in the summer, the cleaning can take longer because of the speed at which the water evaporates. You can ensure that your solar panels are functioning at top efficiency by putting your system on a regular cleaning schedule. Let us know if you’d like to be put on an annual, biannual or quarterly cleaning schedule. In most instances, you don’t even need to be home, so you can book and forget.
