Asymmetric concentrating photovoltaic photo-thermal system capable of realizing fixed installation

Abstract

The invention belongs to the technical field of utilization of solar energy, and especially relates to an asymmetric concentrating photovoltaic photo-thermal system capable of realizing fixed installation. The system comprises asymmetric prism type composite paraboloid condensers, solar batteries and miniaturized heat exchangers, wherein the bottom portions of the asymmetric prism type composite paraboloid condensers are connected with the solar batteries, and the solar batteries are fixed on the outer wall of a building through the miniaturized heat exchangers. Compared to the prior art, the asymmetric-structure prism type composite paraboloid condensers are brought forward innovatively, such a structure can reduce the material cost of a concentrating structure, the purpose of concentrating is realized by use of refraction and reflection of the condensers, and the optical efficiency is quite high. The asymmetric prism type composite paraboloid condensers can ensure that a light receiving angle can meet a requirement during installation with the wall, realize fixed installation to the building and do not require a complex tracking apparatus.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to an asymmetric concentrated photovoltaic photothermal system that can be fixedly installed. Background technique [0002] With the continuous development of human society and the improvement of living standards, people's demand for energy is also increasing. In particular, building energy consumption is still growing at a high speed. It is foreseeable that in the future society, building energy consumption will reach a very large level. As an inexhaustible and inexhaustible clean energy, solar energy can solve a large part of human energy needs if it is well utilized and combined with buildings. [0003] At present, because the price of photovoltaic modules remains high and the cost recovery period is very long, in order to realize the effective utilization of solar energy, many experts and scholars have proposed the comprehensive utilization of Conce...
