Abstract
Worldwide photovoltaic power generation is affected by deposited dust on photovoltaic (PV) systems, which creates soiling losses. In this work, factors that have a detrimental influence on dust deposition and an impact on PV systems performance were reviewed. The different ways that dust deposition can be a barrier for India’s energy security plan involving PV were also discussed. Different available cleaning techniques were also introduced. The nature, size, and morphology of dust particles vary with geographical location. Any increase of the PV tilt angle, or high wind speed and heavy rain showers reduce dust deposition. Deposited dust reduces the incident transmitted light on the PV, which has an adverse impact on the reduction of short circuit current. However, the open-circuit voltage has a reduced effect due to dust deposition. The enhancement of temperature caused by dust-covered PVs is still a debatable area. A universal cleaning technique is required to eliminate the soiling losses from PV. India has a solar mission to generate 100 GW of PV power by 2022. However, India’s poor air quality can undermine efforts to achieve this target.

Energy security entails access to energy resources at an affordable price and without interruptions.The term energy security was first developed during the 1970 oil crisis period, and for the last 40 years, the international community has tried to create a uniform definition for energy security
An experiment showed that the module efficiency of a mono-crystalline silicon, polycrystalline silicon, and amorphous silicon (a-Si) PV cell based system was decreased by 26% as dust deposition increased from 0 to 22 g/m2 [88]
Summary
Energy security entails access to energy resources at an affordable price and without interruptions. Global energy security for different countries came from coal [2] and crude oil [3]. These energy sources produce energy by polluting the environment. The major benefits of using renewable solar sources are benign and noise-free power generation from PV systems, low greenhouse gas (GHG) emissions, and the increasing energy security of a country in a sustainable way [13,14,15,16,17,18,19]. Through the Jawaharlal Nehru National Solar Mission (JNNSM), India has developed a plan to generate 100 GW of PV power by 2022, which will help the country to become an energy secure country.
