Solar trackers are the devices used to orient photovoltaic panels toward the sun to harness more sunlight. Solar trackers are devices which enable solar modules to remain in the best position to accumulate maximum energy from the sun. These trackers are installed in residential, commercial and utility scale solar projects. Solar tracker comprises of numerous components and parts including sun tracking algorithms, control unit, positioning system, drive mechanism system, sensing devices, wind guard, tubes, and rods. Based on the forecast for the coming years, Europe is expected to show a decline in demand for solar trackers. China, the U.S., India and Japan are expected to be the major driving forces for generating the demand for solar trackers. Going beyond the local market is the current trend in the industry and hence, the market is becoming truly global. Key players such as Mecasolar, DEGERenergie, and Titan Tracker are following this trend. Flat-panel photovoltaic (PV), Concentrated Photovoltaic (CPV) and Concentrated Solar Thermal (CSP) are key technologies where solar trackers are applied. Solar trackers have unique functionalities in each application such as minimizing the angle of incidence between the photovoltaic panel and the incoming sunlight in PV applications and orienting the optics in CPV and CSP systems. At present CPV is an emerging technology in the solar energy industry. The CPV system produces low cost solar power due to low manufacturing cost and fewer raw material requirements. Around 85% to 90% solar panels can be recycled due to usage of glass and aluminum as raw materials.
