Abstract
The utility model discloses a solar energy collecting system formed by Fresnel lenses. The solar energy collecting system mainly comprises a first Fresnel lens, a second Fresnel lens and a solar energy photo-electricity conversion device, wherein the upper surface of the first Fresnel lens faces the sun rightly, the second Fresnel lens is mounted below the focus point of the first Fresnel lens, and the solar energy photo-electricity conversion device is mounted below the second Fresnel lens. The utility model adopts a transmission-type optical receiving mode, takes the advantages of the gathering effect of the Fresnel lenses, collects the sunlight, and utilizes a specific optical element or a component group to shape the converging beam of the Fresnel lenses, thereby ensuring that most lights are emitted by changing to be parallel lights or lights approximate to parallel lights and irradiate on the solar battery in a vertical manner or an approximately vertical manner, thereby decreasing the usable space of a photocell and increasing the photoelectric conversion efficiency.
Description
Technical field
The utility model relates to a kind of solar energy utilization system, particularly relates to the solar energy gathering system that a kind of Fresnel Lenses is formed.
Background technology
The form that present solar power generation is adopted is with after the solar panel arrangements, forms the solar energy solar cell array.Solar cell has a variety of, but the price of the sort of solar cell all is very expensive.So a lot of people are exploring under the constant prerequisite of energy output, reduce the usable floor area of cell panel as far as possible.For this reason, people are installed the solar energy gathering system additional in solar panel the place ahead.The solar energy collecting system of commonly using is reflective solar gathering system (as showing 1 intention) mostly, and sunlight projects on the solar panels 3 ' after reflecting plate 1 ', 2 ' reflection.The gathering system capacity usage ratio of this form is not high, and the price of gathering-device itself is also higher.
The utility model content
The purpose of this utility model is to provide a kind of solar energy gathering system that reduces the Fresnel Lenses composition of photronic usable floor area, increase electricity conversion.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of solar energy gathering system of being made up of Fresnel Lenses, and it mainly is made up of first Fresnel Lenses, second Fresnel Lenses and solar energy photoelectric converting device; The described first Fresnel Lenses upper surface is over against the sun, second Fresnel Lenses is installed in first Fresnel Lenses focus below, solar energy photoelectric converting device is installed in second Fresnel Lenses below, is used to receive directional light or approximate directional light from second Fresnel Lenses.
Described first Fresnel Lenses is different with the focal length of second Fresnel Lenses.
Described solar energy photoelectric converting device is a solar panel.
After adopting such scheme, the utility model adopts transmission-type light-receiving mode, utilize the effect of converging of Fresnel Lenses, collect sunlight, utilize specific optical element or element group to finish shaping to Fresnel Lenses institute converging beam, make most light become directional light or the ejaculation of approximate directional light, vertical or near normal shines on the solar cell.Because the utility model can be converted into the sunlight that is received high-intensity directional light or approximate collimated light beam, thereby has reduced photronic usable floor area, increase electricity conversion.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the reflective solar gathering system of commonly using;
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2, the utility model is the solar energy gathering system that a kind of Fresnel Lenses is formed, and it mainly is made up of first Fresnel Lenses 1, second Fresnel Lenses 2 and solar energy photoelectric converting device 3.
Described first Fresnel Lenses, 1 upper surface is over against the sun, and second Fresnel Lenses 2 is installed in first Fresnel Lenses, 1 focus below, is used for sunlight is converted into directional light or approximate directional light; Solar energy photoelectric converting device 3 is installed in second Fresnel Lenses, 2 belows, is used to receive directional light or approximate directional light from second Fresnel Lenses 2.
In the present embodiment, described first Fresnel Lenses 1 is different with the focal length of second Fresnel Lenses 2.
Described solar energy photoelectric converting device 3 is a solar panel 3.
Emphasis of the present utility model just is: utilize specific optical element or element group to finish shaping to Fresnel Lenses institute converging beam, make most light become directional light or approximate directional light and penetrate, thereby vertical or near normal shines on the solar cell.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
