Skilancer solar — Automatic Solar Panel Cleaning System

Power gain vs frequency of cleaning: It is a known fact that cleaning of solar module is important. But it is necessary to understand what exactly should be the cycle time as cleaning cycle is usually associated with a cost. The outcome of the cleaning cycle is that the energy output of the cleaned array (and/or the power plant)increases which would lead to increase in revenue. However it is important to understand whether such increase in revenue would offset the cost of cleaning. Additionally it is also important to understand how often the cleaning cycle is required and would such regular cleaning offset its cost. The energy gain vs the no. of cleaning cycle is shown in Figure below, it is clear that there would be more than 25% of energy lost if no cleaning cycle is undertaken for a month. For one biweekly, one weekly and twice weekly cycle the energy output increases accordingly. For a country like Abu Dhabi where the local climatic conditions are dry and dusty, it makes sense to clean the solar panel once or twice in a week however for country like India, once in a week or two week cleaning cycle is fine.
