Abstract
Description
technical field
[0001] The invention relates to a solar power generation device, in particular to a plane reflection mirror combined light concentrating module used for making a concentrator. Background technique
[0002] Concentrating solar photovoltaic power generation can greatly reduce the cost of photovoltaic power generation. With the continuous improvement of the efficiency of new high-efficiency concentrating cells, concentrating power generation systems will become more and more important in the field of solar photovoltaic power generation. There are many forms of concentrating optical systems. At present, the main application is the parabolic reflective point focusing system. The advantages of this unit are: simple structure, convenient maintenance; easy to upgrade (you can replace the battery with higher efficiency); Variable (multiple combinations can be realized by replacing the flat mirror unit); low cost (low mirror cost, high light-gathering multiple, and re...
Examples
Embodiment Construction
[0012] see figure 1 , figure 2 , the planar reflector combined light concentrating module of the present invention includes a quasi-planar substrate 1 and a plurality of planar reflectors 2 installed on the substrate.
[0013] see figure 2 , the bottom surface 11 of the quasi-planar substrate 1 in the present invention is a plane, and the installation surface 12 for installing the plane reflector has an array composed of a plurality of inclined protrusions 121, and the inclined surfaces of each inclined protrusion 121 have different inclinations respectively. Direction and angle, so that each plane mirror installed on it also has different inclination directions and angles. When assembling the plane reflector combined light concentrating module and the sunlight receiver into a concentrated power generation device, it can be ensured that each plane reflector in the plane reflector combined light concentrating module can concentrate the incident sunlight to the sun. The out...
