In this chapter, a detailed review of soiling prevention methods is presented to increase solar panels' energy capture. We describe both semiautomatic water-based solutions and automatic water-free cleaning solutions. The technical details of an indigenously developed automated, water-free cleaning device to remove soiling of the solar panels are discussed. We compare the energy-capture levels, over the course of a month, for PV panels regularly cleaned using automated solar panel cleaning solution, with that of soiled panels in a local solar-panel installation. The increased yield is measured. One of the most important aspects of the solar-power system, for example, in rooftop solar systems, is the cleaning of the solar panels. There are significant losses due to dirt and soiling of the solar panels. So, it becomes very important to keep the solar panels clean.
