With agricultural lands utilized diversely, there would be no pollution left for our offspring. Agricultural lands, with solar panels built over them, will lack for the sunshine which affects the growth of crops below those panels, thereby influencing the operation of farms. Moreover, due to the government’s latest regulation, agricultural lands were demanded to reach at least seventy percent of the utilization rate of agricultural land. This urged us to discover a brand new solution for both the energy policies and agricultural policies. This research was related to designing an optical system to realize a situation where we are capable of transferring the energy, which is redundant to the crops since they have had enough illumination, to solar panels generating electricity, therefore enabling farmers to exploit their lands in a more economical way. A designed optical system was discussed about its optical performance at a different time in a year, and optimized in a condition where direct rays were taken into consideration. Making use of Fresnel lenses, we could alter the directions of direct rays. Furthermore, generating electricity of solar panels was achieved by putting several mirrors into use. With mirrors controlled properly, we could decide whether crops would be shined or not and make the whole system perform in the way we want.
