Photovoltaic Systems with Sun Tracking Position

Abstract

This paper describes the work of solar photovoltaic systems and the types of photovoltaic panels. Solar energy can be transformed in many ways into electrical, and the simplest way is through photovoltaic cells. The work principles of photovoltaic cell is based on photoelectric effect. Solar panels can be fixed, or mobile panels with one or two rotation axis. Mobile systems can be optimally positioned in relation to the sun, no matter where the sun is in the sky.
