Abstract
ECOSun project has as main objective a cost reduction of electricity and heat co-generation via a Concentrated Photovoltaic/Thermal (CPV-T) system by applying low-cost materials and advanced industrial manufacturing methods. In the CPV-T system, the solar radiation is captured in parabolic through concentrator based on a novel support structure fabricated by injection moulding and focused on a Co-Generation Absorber Module (CAM), where special c-SiPV-cells are operated under concentration. In this work, a preliminary assessment of the energy produced by a polygeneration system (in summer conditions) based on this technology coupled with an absorption chiller is carried out based on system simulations. The calculations are performed using NEST numerical platform, which allows the linking between the different components (solar collectors, pump, valves, heat exchangers, etc.), with high flexibility in the configurations. The simulations give information on the principal performance indicators of the systems, e.g. solar fraction, collectors’ efficiency, PV modules’ efficiency, and thermal and electrical COP of the absorption chiller. The simulations also estimate the electrical expenses of the auxiliary components (pumps, fans, etc.). From the cases simulated, the electrical expenses resulted in up to 25% of the electricity produced.
