Design of Light Compensation System for Agriculture under Solar Panel
Keywords:solar farm, light compensation, dual land use
In this research, a controller was designed for a light compensation system under a solar panel. The shadowed areas under the panels are compensated by the light compensation system created for the research. The shadowed areas under the panels and the efficiency of the light compensation system were studied as well. It was found that the shadowed area increased from morning until noon (9.00 A.M. – 1.00 P.M.) and then decreased until evening (1.00 P.M. – 4.00 P.M.). The largest shadowed area, amounting to approximately 66.30%, was achieved at noon. However, 97.88% of the shadow could be compensated by adjusting the tilt angle and the sweep distance of the mirror; every single shadowed area was compensated for approximately 21.83 minutes per hour. The primary energy consumed by the system was approximately 0.42 watts. These results could be useful for dual land use to achieve good efficiency, especially for a short-day plant.
