Generation of electricity by improving dual axis solar tracker using Arduino

Abstract

Using a range of technologies such as photovoltaic, thermal electricity and etc solar cell (also called a photovoltaic cell) is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. A solar panel is a set of solar photovoltaic modules electrically connected and mounted on a supporting structure. The majority of modules use wafer- based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural member of a module can either be the top layer or the back layer. Electrical connections are made in series to achieve a desired output voltage and in parallel to provide a desired current capability. Several types of solar cells are available.silicon solar cell,thin film solar cell,multijunction solar cell and new technologies including organic solar cell.
