Photovoltaic and Thermal Solar Concentrator Integrated into a Dynamic Shading Device

Abstract

The paper addresses the problem of designing efficient shading devices for buildings. The novelty of this project is a dynamic design for shading devices, new in the market of photovoltaic and concentrator systems, that changing orientation and configuration, allows the best lighting comfort in buildings while producing energy.This device consists of a series of linear low concentrator with monoaxial sun tracking and a semi-parabolic profile reflector providing the solar radiation concentration into a string of mono-crystalline cells PV, with 5,5x concentration factor. The thermal energy production is achieved through the cooling system of the device whereby hot water is produced.The contribution of this study is a new concept and developments in solar thermal concentrator systems revealing new trend for the technology to be integrated into architecture, especially in dynamic solution for shading devices.
