Abstract In this study, we aimed to attempt the output improvement of PV Cell by Solar Energy Collecting System with Flesnel Lens (SEC system). We examined installation requirements of PV cell and the Fresnel lens, and tested SEC system. We used a convex type and a linear type Flesnel lens. Because a convex type had caused the decrease in the output because of the shadow with the frame of the lens, installation requirements were examined for linear type. The results are as follows: (1) We derived the formula for the determination of best installation distance between PV cell and linear type Flesnel lens. (2) The effect of the PV cell output improvement by SEC system is larger than the decrease of PV cell power output by rise of the temperature. (3) It was clarified that it was more effective to set up the linear type Flesnel lens in the range of low quantity of solar radiation.
