This document describes a 10 tube solar collector system with CPC (compound parabolic concentrator) technology. The collector uses a vacuum tube design with a coaxial copper heat exchanger inside each glass tube to efficiently transfer heat. Key features include high insulation, an impact resistant double wall glass tube, and a CPC concentrator to maximize efficiency from diffuse sunlight. The collector is suitable for roof or facade mounting and produces over 1200W of peak power.
