Common Mistakes And Misconceptions

Mistake/Misconception	Correct Viewpoint
Solar panels do not need cleaning because they are self-cleaning.	While it is true that solar panels have a self-cleaning mechanism, it may not be enough to keep them clean all the time. Dust, bird droppings, and other debris can accumulate on the surface of the panel over time and reduce its efficiency. Therefore, regular cleaning is necessary to maintain optimal performance.
Cleaning solar panels is dangerous and should only be done by professionals.	While there are risks involved in cleaning solar panels, such as falling off a ladder or damaging the panel itself, it can be done safely with proper precautions and equipment. Homeowners can clean their own solar panels if they follow safety guidelines provided by manufacturers or seek professional help if needed.
Using soap or detergents when cleaning solar panels will damage them.	It is important to use mild soap or detergent when cleaning your solar panel as harsh chemicals could cause damage to the glass surface of your panel which could lead to scratches that would affect its efficiency negatively over time.
Rainwater will effectively clean my solar panels for me.	Although rainwater helps remove some dirt from your panel’s surface but this isn’t always enough especially in areas where rainfall isn’t frequent enough so you might still need to manually clean your PV system regularly even after rainfall events.
I don’t need to worry about maintaining my PV system since it has no moving parts.	Even though photovoltaic systems have no moving parts doesn’t mean they don’t require maintenance like any other electrical appliance at home; dust accumulation on top of modules reduces energy output hence reducing overall performance thus making routine maintenance very crucial for optimal operation of these systems.
