To begin with, solar panels are made out of an array of photovoltaic cells. It is mainly used as a part in a larger photovoltaic system to produce electricity for commercial and residential applications.
Solar panels come as clean and environmentally sound devices, making use of renewable energy from the sun. These panels being environment friendly in nature, can make use of the sun’s energy, available in abundance on our planet and convert it using the advanced technology.
The basic mechanism of solar panels is to use light energy (photons) from the sun to generate electricity through the photovoltaic effect. Most of the modules use wafer-based crystalline silicon cells or a thin-film cell based on cadmium telluride or silicon. The Crystalline silicon used for the purpose is derived from silicon, a commonly used semi-conductor. For the cells to be used for practical applications, they must be connected electrically to one another and to the rest of the system. It has to be ensured that they are protected from mechanical damage during manufacture, transport or installation. Lastly they must be protected from moisture, which corrodes metal contacts and interconnects,thus decreasing performance and longevity.
Being encouraged by the government, people today are opting for solar panel based systems, setting up solar power plant. Solar Products such as Photovoltaic Modules, Silicon Cells, Silicon Wafers, Lanterns, Street Lighting, Solar Powered Fans, Air Coolers, Cooking Systems, Solar Water Pumps and Solar Water Heater are coming into existence by and by.
