Abstract
The utility model provides a sunlight collecting template, which is characterized in that edge strips of which the sections take a shape of triangle are distributed on the surface of the sunlight collecting template. The sunlight collecting template has the advantages of capability of capturing sunlight omni-directionally, increasing light transmittance, better light collection performance, increasing of daily electric energy production and high stability.
Description
[technical field]
The utility model relates to a kind of photovoltaic power generation system, particularly a kind of sunlight light harvesting template.
[background technology]
General photovoltaic power generation system, its surface all is that glass or plastics are that basal disc constitutes flat surfaces, it is near horizontal direction that dull and stereotyped light sees through, because the light angle of one day sunlight is all changing, angle of sun rays throughout the year also can constantly change, therefore light penetration greatly lowers and is unstable, thereby causes day energy output little and unstable.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of sunlight light harvesting template, and light penetration increases, and day energy output is big and stable.
The technical problems to be solved in the utility model is achieved in that a kind of sunlight light harvesting template, it is characterized in that: it is leg-of-mutton rib that the surface of described sunlight light harvesting template is covered with the cross section.
Described rib the cross section be highly for the isosceles triangle of μ meter level.
The plastics that described sunlight light harvesting template is high printing opacity are made.
Advantage of the present utility model is: this sunlight light harvesting template, can comprehensive seizure sunlight line, and light penetration increases, and catch rate is greatly improved, thus the light harvesting better performances, day energy output increases and is more stable.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of the utility model sunlight light harvesting template.
Fig. 2 is the light harvesting theory structure schematic diagram of the utility model sunlight light harvesting template.
Fig. 3 is the light harvesting theory structure schematic diagram of the utility model sunlight light harvesting template.
[embodiment]
See also shown in Figure 1, it is leg-of-mutton rib 12 that the surface of sunlight light harvesting template 1 of the present utility model is covered with the cross section, arbitrary rib all has one first side 121 and one second side 122, and this first side and 121 and second side 122 is the inclined-plane can comprehensive seizure sunray.Described rib 12 the cross section be highly can be the isosceles triangle of μ meter level, and this sunlight light harvesting template can make with the plastics of high printing opacity, but not limit by this.
Operation principle of the present utility model:
As shown in Figure 2, the incident light of the normal direction of this sunlight light harvesting template is because the initial face of accepting is second side 122 of described rib 12, because this second side 122 is the inclined-plane, so a part is incident to the inside of rib 12 by this inclined-plane, part reflection back is incident to the inside of adjacent rib 12 to the normal direction of first side 121 of adjacent rib 12.Final this sunlight light harvesting template comprises reverberation and incident light can capture efficient more than 99.9%.
Again as shown in Figure 3, sunlight more than 60 ° the time, its be relative rib 12 first sides 121 near vertical incident, at this moment also have 96% light incident.This flexion light produces total reflection in second side 122 of rib 12 inside.Remove beyond the reverberation that the initial face of accepting is first side 121, also can capture 96% outer light catch rate in the crystal face.Therefore, in angle of incidence of light ± 60 degree scopes, has the light harvesting performance more than 99%.
In sum, sunlight light harvesting template of the present utility model, the catch rate of light sharply rises in comprehensive angle scope.And light penetration increases, and catch rate is greatly improved, thus the light harvesting better performances, and day energy output increases and is more stable.
