Es un sistema idóneo para los sitios de baja latitud. Sin embargo, una de sus limitaciones es que requiere una mayor superficie que el sistema de ángulo fijo (SAF) para una misma potencia. Para aumentar el índice de ocupación del terreno (GCR) desde hace unos años se han desarrollado HSAT con seguimiento retrasado (HSAT-B). Mediante esta tecnología, cuando debiera comenzar el sombreado mutuo de los módulos, el seguimiento se retrasa para evitar el sombreado de la radiación directa. Como Cuba es un pequeño archipiélago con limitaciones de áreas para la instalación de parques fotovoltaicos, los autores comparan esta tecnología con el SAF y con el sistema de doble orientación Este-Oeste (SEO), y concluyen que, ante limitaciones de terreno y de acuerdo a las características del sitio, el seguimiento retrasado es otra alternativa a evaluar.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT 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.]]></p></abstract>
