Even though these structures are set to collect a high proportion of available noon-time energy, they still fail to generate the same amount of energy during early mornings or evenings, due to missalingment caused because of the suns position in relation to these structures. Thus, in order to get maximum genartation of a solar system, solar tracking becomes necessary solar tracker is a technology that is designed to harness the maximum amount of solar energy from the Sun, by orienting or aligning the payload towards the sun. Apart from being used to focus the arrays of photovoltaic (PV) solar cells directly to the sun, they are also used for focusing mirrors, reflectors or lenses that are used for concentrated solar power units.
Through the day the sun keeps changing its angle constantly. These trackers help the PV arrays, mirrors, reflectors and other devices track the sun and minimize the angle of incidence by ensuring that the sun’s rays fall in a more or less perpendicular angle.
These devices use energy generated from the solar power plant itself, to continually orient the solar device towards the sun, however this energy input is more than offset by the increased efficiency gained through the use of the tracker. Trackers help in producing more energy as the Solar Panels or Mirrors (CSP) will be fully exposed to sunlight. Tracker performs the tilting and turning operation by following the sun movements using Astrological Predictions. The tracking system helps in collecting energy from the sun for the longest period of the day ensuring the most accurate alignment to the sun, which shifts with the season.
