Experimental Study on the Impact of Airborne Dust Deposition on PV Modules Using Internet of Things

The increasing demand for Various energy sources have emerged as a result of energy and alternatives, but PV systems have shown to be the most efficient. This level of reliance on solar power is obvious given with reliable power supply and minimal adverse effects. There are still other problems that have an adverse effect on the operation of PV systems, including as temperature-induced voltage drops that cause solar power to be lost and dust buildup (soiling). Dust accumulation has a major impact on the optical properties of PV modules, which lowers the output of generated photocurrent. The performance of solar cells is influenced by both inner and external considerations, including location, manufacturing processes, wind, dust, humidity, and other environmental factors. The efficiency of solar systems is influenced by a variety of elements, including temperature, ageing, wind, radiation, pollution, shade, and cleanliness. Dust is a type of minute particles that are released into the air by building sites, windstorms, and industry pollutants. Either it is visible or it is not. This project’s goal is to employ thing speak web server to analyzed how dust affects the performance of the PV system at SRM University in Chennai. The characteristic curve was used to compare all the significant characteristics (output power, short circuit current, open circuit voltage, etc.) relevant to the two panels. After 45 days, there was a 7.5% drop in the soiled panel’s ability to generate electricity.
