Solar Panels Cleaning  - City CleanSolar Panel Cleaning

Many residents have been sold the cost/benefit analysis for solar payback based on the optimum performance output of those panels.  Unfortunately what they didn’t tell you at the time was that these panels need to be cleaned to achieve those results.  Did you know an unclean panel’s efficiency can reduce its power generating output by to 25%?  The good news is that the cost of the cleaning will be more than offset by the increased efficiency of your panels.

You made a great investment that will cut the costs of your heating and electricity bill and help to protect the environment. Solar panels are made to last at least 30 years, or more. Over the course of time though, bird droppings, dust and pollution can get baked in on the glass and actually lower the output.

So, how do you increase the output? If your solar panels are dirty the answer is by having them cleaned. Google conducted a study on their office solar panels.  They measured the output before and after the cleaning, and the results were phenomenal! (36% increase in output after cleaning).  You can see the study done by clicking the link Google Study.

Many suggest to use just a garden hose and rinse the dust off. While this is effective to some degree, the problem is the TDS (total dissolved solids) in the water. Just running regular hose water will not clean the glass on the surface, only rinse the dust off the glass.

The process to cleaning your solar panels is very much the same as it is for window cleaning. After all, the photovoltaic cells are protected by a glass window. You cannot clean the windows with a garden hose, you know what will happen; it’s going to leave a bunch of spots. This in the long run will reduce the output just as it would if your panels were dirty.

The best possible way to clean those panels is by using a pure water system and a water fed pole. Purification systems bring the TDS of the water to zero, and the water fed pole can clean the angled panels from the ground in most cases removing all contaminants (if regularly maintained). On roofs or areas where the panels lay flat or at a slight angle, the same system is used, which makes the cleaning fast, efficient, Eco friendly and affordable.  Alternatively traditional window cleaning methods can be used.

Ultimately the cost of cleaning is more than offset by the increased power generating return.
