Roofing Solar Panels of Planar and Concentrator Designs

Abstract

Solar roofing panels fulfill both building protective functions and energy generating ones. The composition of the substrate of the solar roofing panel includes secondary raw materials, which has a positive effect on the environment. To increase the electrical efficiency and also to obtain thermal energy in the form of warm water, it was proposed to create a photovoltaic thermal roofing panel. For this purpose, the presented article describes the method of creating a three-dimensional model of solar photovoltaic thermal modules in a computer-aided design system. The article also proposes a method for manufacturing a prototype body for a solar roofing panel, manufactured using additive technologies, which will significantly reduce costs at the initial stage of creating a prototype due to the possibility of operational changes to a three-dimensional model followed by printing a modified and optimized model. To reduce the number of photovoltaic cells and the cost of a solar roofing panel, it is proposed to use a solar concentrator in the panel.
