Abstract
The utility model relates to a sunlight board spotlight solar energy cell device, comprising a transparent lighting roof board and a solar cell panel. The bottom surface of a sunlight board in the lighting roof board is made into a straight line type Fresnel lens. A plurality of solar cell panels are straightly tiled on a plane. The plane is arranged under the sunlight board and is positioned on the position with a certain distance away from a focus belt of the Fresnel lens. The distance leads the sunlight after focalizing to irradiate on the solar cell panel. The spotlight width is two to three times of the array of the solar cell panels. The spotlight belt is emitted on the solar cell panel, thus improving the utilization efficiency of the solar cell. The device also can ensure that light strips can fall on the solar cell panel for longer time by day, and has the advantages of low cost and long service life.
Description
Technical field
The utility model relates to the solar energy power generating field, particularly a kind of solar battery apparatus with beam condensing unit.
Background technology
Solar energy is a kind of clean energy resource, and it is free from environmental pollution; The solar energy mankind relatively is inexhaustible, so the utilization of solar energy has broad prospects.Countries in the world are all in the research and development of greatly developing solar energy with utilize technology, by solar energy alternative ore production of energy electric energy.But present solar energy generation technology also exists many problems, though the manufacturing application technology of solar-energy photo-voltaic cell reaches its maturity, can only reach about 18% but the solar cell photoelectric transformation efficiency is the highest at present, and costing an arm and a leg of solar panel can't be realized commercial operations and large-scale development.
Relevant research has been found that, solar cell can bear the light intensity higher than normal sunshine, if improve the receiving light power of solar cell by optically focused, electricity conversion just can further improve, the relative cost of solar cell can obviously reduce, thereby reaches the target of solar electrical energy generation commercial operations.Improve the efficient of solar electrical energy generation by optically focused, some reports had been arranged both at home and abroad, such as utilizing concentrator and solar tracking system is set, but more improved the cost of solar electrical energy generation like this.Consider at present domestic various daylighting tops in senior office space, large-scale hotel art zenith, industrial factory building, public daylighting facility and civilian sunlight room, bicycle shed, propaganda board etc. locate to be extensive use of, some light transmittance has reached 90%.And various sunlight board production technologies are ripe, if directly utilize sunlight board optically focused, can improve the electricity conversion of solar cell under the prerequisite that does not raise the cost.
The utility model content
The purpose of this utility model is to provide a kind of low-cost sunlight board concentrating solar cell device that improves solar energy generating efficiency.
The technical solution of the utility model is: a kind of sunlight board concentrating solar cell device, comprise transparent daylighting top and solar panel, straight burr type Fresnel Lenses is made in the bottom surface that it is characterized in that sunlight board in the daylighting top, the polylith solar panel with the strip tiling in one plane, this plane places the sunlight board below, the focus band that is positioned at Fresnel Lenses is up and down on the position of certain distance, this distance makes the sunlight behind the optically focused become a band shape to be radiated on the solar panel, and the optically focused bandwidth is 2～3 times of solar panel array.
The utility model has the advantages that: the sunlight board bottom surface is manufactured Fresnel Lenses, become the optically focused sunlight board, the sunlight band behind the optically focused is radiated on the solar panel, has improved the intensity of illumination of solar cell, has promptly improved the utilization ratio of solar cell.Because daylighting top area is generally bigger,, can make the sunlight behind the optically focused reach natural 2～3 times much larger than the cell panel column width.In addition, along with the deflection of the sun, this device can guarantee that the long by day time all has light belt to drop on the solar panel.It is few that solar panel in this device is influenced by the nature wind and rain, long service life.Owing to be that the original daylighting top of building is improved, this device also has advantage with low cost.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an A place amplification assumption diagram among Fig. 1.
Fig. 3 is an optically focused effect schematic diagram.
Description of symbols among the figure: 1 sunlight board, 2 supports, 3 solar panels, the optically focused rib of 4 Fresnel Lenses, the focus band of 5 Fresnel Lenses.
The specific embodiment
With reference to Fig. 1, Fig. 2, straight burr type Fresnel Lenses is made in the bottom surface that is used to build the sunlight board 1 of daylighting top, promptly make optically focused rib 4 with many different angles, optically focused rib 4 is for directly to arrangement, make solar ray collecting on a linearity focus, this technology is the widely used known technology of existing Fresnel Lenses.
Polylith solar panel 3 with the strip tiling in one plane, this plane places sunlight board 1 below, particular location is in conjunction with shown in Figure 3: solar panel 3 is positioned on the position of focus band certain distance about in the of 5 of Fresnel Lenses, present embodiment is placed on the top of focus band 5 with solar panel 3, also can be placed on the below of focus band 5 when specifically implementing as required.
5 distances that have of solar panel 3 and focus band make the sunlight behind the optically focused become a band shape to be radiated on the solar panel, rather than a line, burn to prevent solar panel.
The optically focused bandwidth is 2～3 times of solar panel 3 arrays, as shown in phantom in FIG..
As shown in Figure 3, the sunlight band behind sunlight board 1 optically focused is radiated on the solar panel 3, has improved the intensity of illumination of solar cell, has promptly improved the utilization ratio of solar cell.Because the daylighting top area of building is generally bigger, promptly sunlight board 1 is much larger than the width of solar panel 3 arrays, can make the sunlight behind the optically focused reach natural 2～3 times.
Because the optically focused bandwidth is 2～3 times of panel array, along with the deflection of the sun, this device can guarantee that the long by day time all has light belt to drop on the solar panel.
