Is Solar Panel Cleaning Worth it in California?
When discussing solar panel cleaning, the average owner of solar panels will say that it is not worth getting your solar panels cleaned. This is mainly due to the fact that rain does a decent job of removing some dirt and debris from your panels.
Now, I ask you Ventura County, when was the last time that we had a day of solid rain? Not the kind of rain that makes your car look blotchy because the dirt pooled up and then dried shortly after. A study published in Renewable and Sustainable Energy Reviews found that the dust accumulated on solar panels affects the overall amount of energy created by the solar panels on a daily through annual basis.
Places on the East coast that receive a much higher amount of rainfall per year see an average of 1% degradation of power due to dust and debris, with the highest reaching 4.7%. In Southern California and especially Ventura County, not only do we see a worse average degradation of power but we also see higher degradation of powers up to 6.2%.
6.2% degradation over each panel will accumulate to greater losses in energy production and a greater loss in potential money saved. Having your solar panels cleaned by companies like Kelly Cleaning will ensure that you are making the most out of your solar panels.
With California and Ventura County’s seemingly annual drought and sadly more than common wildfire, these factors play a role in your potential energy production. We recommend that you clean your panels yearly in order to reset your panels to from-factory levels of production. Go look at your solar panels or see your monthly energy production to see if there is a difference from when you first had them installed. If they are in need of cleaning or if you are ever in doubt Kelly Cleaning will visit your location and recommend the best cleaning solution for your panels.
