How to deal with the dust around photovoltaic panels
The new system uses electrostatic repulsion to cause dust particles to detach and virtually leap off the panel’s surface, without the need for water or brushes. To activate the system, a simple electrode passes just above the solar panel’s surface, imparting an electrical charge to the dust particles, which are then repelled by a charge .

Dust on solar panels reduces their output significantly, so they need to be kept clean. But what’s the best way to do that? Scientists at the Massachusetts Institute of Technology (MIT) say.
To reduce the impact of dust on solar panel surface, a robotic arm-based self-automated dust removal system was designed and developed using IR sensor. The proposed robotic arm was also capable of doing clean under different modes of operations based on day and night time along with temperature monitoring to avoid overheating.
Ultimately, a detailed strategy for dust prevention in PV panels is proposed, involving real-time monitoring, assessment of dust deposition, mathematical modeling for predicting performance losses, and informed decision-making regarding optimal cleaning measures to enhance panel efficiency.
The methodology is built around two central questions, which are (1) What are the impacts of dust on PV panels, and (2) What are the techniques used to mitigate, and clean, dust accumulation on PV panels?
