Solar PV panels, also called photovoltaic panels, are instruments designed to convert sunlight into electricity through the photovoltaic effect. They are made up mostly of countless solar cells of silicon that, when the sun shines on them, blend light and release electrons (creating an electric current). Solar PV panels are green power sources. With zero emissions, they are nature's donation later savored by mankind as a kind of electricity without pollution and operating problems: with 26 gays cottony and an expected life-cycle return rate above 99%. Technical features of these panels generally include high efficiency levels, strong durability, and an anti-reflective coating to absorb maximum sunlight rays. They are widely used in Western developed countries as well for poverty alleviation; they in addition serve as needed backup supplies in hospitals, traffic lights, water systems etc. Solar PV panels are an environment friendly and sustainable alternative to satisfy the power demands of our modern world.
