The horizontal single-axis tracker system (HSAT) moves collectors changing the East-West orientation to track the sun´s position during the day. However, as a limitation, it requires a higher area than the fixed tilt system (SAF) for the same power. Recently, HSAT with backtracking (HSAT-B) has been developed to increase the ground cover ratio (GCR). By backtracking, modules move such that no mutual beam shading occurs. As Cuba is a small country with land constraints for construction of new solar farms, the authors compared the HSAR-B with the SAF and. the East-West orientation system (SEO), and concluded that, facing land restrictions and taking into account the specific characteristics of the site, the backtracking is other technology to assess.
