Rotating Prism Array for Solar Tracking

Solar energy has become one of the most promising renewable energies being the most widespread used nowadays. In order to achieve an optimum performance, both photovoltaic and solar thermal applications require the use of some kind of solar tracking technique. Every solar concentration system has to constantly reposition itself according to the Sun's position changes throughout the day. This movement must be done in the most effective way as possible to avoid a high negative impact on the system efficiency.
