Polygonal mirror type light concentrating photovoltaic photo-thermal integrated device

Abstract

The invention provides a polygonal mirror type light concentrating photovoltaic photo-thermal integrated device comprising a receiver (1), a light concentrating unit (2) and a tracking unit (3). The light concentrating unit (2) reflects and concentrates solar energy to the receiver (1). The monocrystalline silicon cell (1-1) of the receiver (1) directly converts the solar energy into electric energy, and cooling water is piped into the cooling channels (1-3) to cool the monocrystalline silicon cell (1-1) so that the cooling water of certain temperature is acquired and heat and power cogeneration can be realized. As for the light concentrating unit (2), fine adjustment of the position of the plane mirror (2-1) can be performed by adjusting the position of the adjusting nuts (2-3). The receiver (1) and the light concentrating unit (2) are installed on the tracking unit (3) so as to realize the solar light concentrating function.

Description

technical field [0001] The invention relates to a multi-mirror type concentrating photovoltaic photothermal integrated device, in particular to a multi-mirror type concentrated photovoltaic photothermal integrated device, which belongs to the technical field of solar heat collection. Background technique [0002] As a clean, non-polluting renewable energy source, solar energy is considered an important part of the world's energy strategy for its development and utilization. Solar photovoltaic power generation systems have been built on a large scale, but the cost of photovoltaic power generation has been high, restricting its development. Concentrating technology is to use cheap mirrors to partially replace batteries, thereby reducing the cost of photovoltaic power generation. [0003] Concentrating photovoltaic systems use cheap concentrating mirrors to partially replace expensive batteries, thereby reducing the cost of photovoltaic power generation systems. The photoelec...
