<P>PROBLEM TO BE SOLVED: To provide a condensing type photovoltaic power generation unit and device, in which reduction of condensing efficiency and deterioration of sealability are difficult to occur although a resin lens and a metallic case are used. <P>SOLUTION: One condensing type photovoltaic power generation unit 1 where a homogenizer 3 and a photovoltaic power generation element 4 are assembled in a holding member 5, a Fresnel lens 2 is assembled to block an opening at an upper end of the case 6 and the holding member 5 is assembled to block an opening at a lower end of the case 6 so as to store the photovoltaic power generation element 4 internally can be manufactured. One Fresnel lens 2 is assembled at every case 6 so as to make it a unit. Thus, the other condensing type photovoltaic power generation unit 1 is not affected even if warp and distortion occur in the Fresnel lens 2 due to a thermal expansion difference between the resin Fresnel lens 2 and the metallic case 6. <P>COPYRIGHT: (C)2012,JPO&INPIT |
