Design and Practical Evaluation of the PVT Concentrator System Concept

Abstract

The purpose of this work is to propose a novel and effective photovoltaic-thermal hybrid solar system (PVT) with thermal and electrical output for small households. Such design allows the use of standard industrial photovoltaic modules in areas with low solar irradiation. The base of the system is a parabolic solar concentrator that increases the density of an irradiation flow on the photovoltaic module surface. To prevent the system from damage caused by overheating, redundant thermal energy can be used in a house heating system or should be removed by a cooler, boiler, etc. The proof of concept has been realized as a standalone PVT system with thermal and electrical output and successfully tested under natural conditions.
