Solar trackers are devices that orient various payloads, whether they be solar photovoltaic (PV) panels or reflectors, toward the sun. In flat-panel PV applications, trackers are used to minimise the angle of incidence between the incoming light and a PV panel. This increases the amount of energy produced from a fixed amount of installed power generating capacity. In standard PV applications, trackers are used in around 85% of commercial installations greater than 1MW.
In concentrated PV and concentrated solar thermal applications, trackers are used to ensure the sun enters the optical components of these systems, otherwise they do not work.
Spanish manufacturer and a leader in the solar tracking field, Titan Tracker, has just finished a new generation of dual-axis solar trackers which it estimates can achieve a cost reduction of about 30%.
The firm is specialised in the design, manufacturing and commercialisation of dual-axis trackers not only for conventional flat-plate PV but also for concentrating PV and concentrating solar power (CSP) tower and Stirling applications.
“These new products also include the highest performance and technological advantages of the TITAN concept, for instance more energy yield up to 45% more than fixed systems (30º tilt to South) in 40º North latitude in conventional PV or extreme accuracy better than 0.01 degrees in concentrating PV and CSP Stirling and tower,” explained the company in a recent press release.
