FRESNEL LENS FOR CONCENTRATED PHOTOVOLTAIC POWER GENERATION DEVICE, CONCENTRATED PHOTOVOLTAIC POWER GENERATION SYSTEM, AND METHOD OF MANUFACTURING FRESNEL LENS FOR CONCENTRATED PHOTOVOLTAIC POWER GENERATION DEVICE

摘要

A Fresnel lens for a concentrated photovoltaic power generation device (32f) is provided with: a glass substrate portion (61) having a disc-shaped first angular portion (613, 618); and a synthetic resin portion (62) which covers one surface of the glass substrate portion (61), has the same radius as the first angular portion (613, 618), and includes a disc-shaped second angular portion (623, 628) coaxially overlapping the first angular portion (613, 618).
