It’s been a controversial topic of discussion for some time now and plenty of research has been contributed by scientists and economists all over the world. So, is there any real benefit to regularly cleaning your solar panels?
Based on recent studies performed by Google at their solar farm in California it was shown that solar panels that were in operation for a period of 15 months without cleaning vs after being cleaned showed a whopping 50% increase in their electricity output. This figure is genuinely higher than even we believed. The study showed that rain is not satisfactory in washing away fallen debris and contaminants found on the panels and that even after rain the panels still failed to produce their highest output and lost 12% in electricity production.
Studies also found that using a hose to clean panels either on the roof or from the ground left a residue on the panels which is caused by hard water. The hard water leaves a residue once dried which actually blocks more light than dust and can actually make the problem worse. Solar panels should only be cleaned using de-iodised water and a solution to prevent streaking and residue.
Unbeknownst to most solar panel owners, they are actually required to have their panels cleaned on a regular basis to honour their warranty. If a fault or problem is found with the panels and they haven’t been cleaned based on the requirements of their warranty they could jeopardise their ability to have the panels replaced by their manufacturer. You can check with the manufacturer of your system by contacting them directly or checking the information provided to you following the purchase of your panels.
So there you have it. Solar panel cleaning is a big tick and will effectively:
