Solar industry has been paying lots of attention to coating technology in the past 10 years. Solar energy is considered the future of alternative energy sources. It has been recognized as one of the most widely used renewable sources of energy in the few recent years for its non-polluting characteristics which combats the Greenhouse effect on global climate created by the use of fossil fuels, figure 1.6. The generation of solar power is done by converting the solar energy into electricity by using either photo-voltaic (PV) solar cells (direct method) or concentrated solar power (CSP). Photoelectric effect is used by PV cells to convert solar energy into electric energy. With the rapid growth of solar energy harvesting as a clean source of power, the enhancement of solar cell efficiency grabs more attention nowadays. Figure 1.6 Qatar foundation smart grid (GreenGulf, 2015) Solar panel conversion efficiency is reduced by dust, grime, pollen, and other particulates that accumulate on the solar panel. Due to excess dirt, the whole panel can be switched off in certain situations (see figure 1.7). The solar industry recognizes this as a major issue and recommend cleaning photovoltaic panels every few weeks or more regularly in dirty environments. Cleaning dirty panels with commercial detergents can be time-consuming, labor intensive, costly, hazardous to the environment, or even corrode the solar panel frame. Besides, in most of the solar panel sites especially in middle east
