New Delhi: Atmosphere is changing at present. People are facing many difficulties as the global temperature is rising and the natural sources of water are constantly declining. According to environmentalists around the world, the biggest conflict in the near future will be over water. Researchers at the Massachusetts Institute of Technology have developed a method to conserve natural water resources, with efforts to alleviate such conditions. Which will be used to clean the solar panel. With the use of which the saved water will be able to provide drinking water to 20 lakh people.
- 10% of the world’s population is using solar energy
- 10 billion gallons of water are spent cleaning solar panels
- Dust accumulating on the solar panel reduces its efficiency by 30% in a month
- Failure to do so could result in a loss of about લાખ 200,000 per year
Currently, 10 percent of the world’s population is getting light from solar energy. While about 10 billion gallons of water are used every year to clean these solar panels. These solar panels are usually installed in desert areas where sunlight is abundant. The dust present on these panels reduces the efficiency of these photovoltaic panels by 30% in a month. It is cleaned at short intervals so that its capacity is not reduced and more water is used to clean it. Properly covered, it will withstand a great deal of adverse conditions.
To solve this problem, MIT researchers have found a way to automatically clean these panels without using a single drop of water. The water that will be saved by this new discovery will provide drinking water to 2 million people. Researchers have used electrostatic repulsion to clean the panel without water. It is a method that will use electrostatic force to remove dust particles. Which will be able to clean the dirt and dust on the surface of the panel. The special thing about this method is that it does not require any kind of brush or water for cleaning, it will clean itself. For this process an electrode will be passed on the surface of the solar panel which will give an electrical charge to the dust particles present on the surface and thus the dust particles will be removed from the panel.
Researchers estimate that about 10 percent of the cost of installing a solar panel comes from cleaning it. Researchers believe that this new system requires only electrodes, including a simple metal rod. As it passes over the panel it will generate an electric field from which the dust particles will separate. Researchers say the system is working successfully in the laboratory. The experiment was performed using it at a humidity of 5 to 95 percent. Researchers found during the experiment that it is difficult to remove dust particles when the humidity is low. After the experiment, the researchers recommended that both sides of the panel be covered with rods. This allows the electrode on the panel to rotate and the whole process is automated.
