PROBLEM TO BE SOLVED: To obtain a condenser for a transmission-type condensing method solar power generating system which can be formed into a large-sized thin body with high accuracy and high transfer property without deformation due to influences of moisture absorption and which has excellent transparency and weather resistance, by using a polymer resin having an alicyclic structure to constitute the condenser. SOLUTION: This condenser for a transmission-type condensing method solar power generating system is made of a polymer resin having an alicyclic structure. The resin has excellent transparency and weather resistance, hardly causes pyrolysis or hydrolysis in a molding machine even when the resin is molded at a high temp., and a large-sized thin condenser can be formed with good accuracy. Since the resin is excellent in fluidity in a fused state, transfer defects are hardly caused when projections to condense light are formed. The molded product hardly causes deformation by moisture absorption and is hardly causes cracks or warpage. Therefore, when the product is used for a solar power generating system, it hardly causes shift in the focus point on solar cells and high energy conversion efficiency can be maintained. |
