Il devient de ce fait possible d'éliminer le problème des ombres des panneaux solaires individuels générées pendant la poursuite, d'installer les panneaux solaires de façon compacte et d'augmenter la quantité d'énergie produite par unité de surface. En plus du fait que le système suit les changements de la hauteur du soleil, il est possible d'améliorer significativement l'efficacité de production énergétique. La base étant amenée à tourner à l'aide d'un moyen de rotation unique, il existe également un effet réducteur de coût.
