Description
Technical field
The utility model belongs to technical field of solar, relates to a kind of device that reduces solar power system tropical island effect.
Background technology
Because solar cell is just to produce electric energy by the irradiation of sunlight, so in the time having barrier to block the sunlight of solar photovoltaic assembly, the performance of solar module will be subject to serious impact, even if appearing at, slight shade on solar panel, also may make the performance of solar panel reduce by 80%, therefore reduce and to eliminate the shade of various barriers extremely important in the mounting design of solar photovoltaic assembly.Now; for eliminating or avoid the impact of the shade of barrier; after choosing the place that solar components is installed, also to confirm whether condition below can meet: in any one month in 1 year, the sunlight on solar module can not blocked by other barrier; Within the time of solar photovoltaic assembly efficiency operation, be between the 09:00-15:00 of every day, solar photovoltaic assembly must not be subject to the impact of shade, if cannot get rid of the factor that produces shade in reality, can consider so solar module to move to suitable place in addition.Cause like this waste in place, the waste of resource, totally unfavorable to the popularization of solar power generation.
In addition, the illumination of sunlight is throughout the year constantly to change, and this has brought very big inconvenience also to the installation of solar module, because the energy-storage battery capacity of solar energy is certain, when the maximal illumination of the some day of solar components in 1 year of installing, energy output can not exceed the heap(ed) capacity of energy-storage battery.But also to meet the requirement of the minimum energy output of user.Solar power generation daily output unlike thermal power generation, hydroelectric power generation is stable, and is subject to the impact of weather also very large, and this just requires solar power system energy output will have certain stability, and every daily generation fluctuation can not be too large.
Summary of the invention
The utility model, for above-mentioned the deficiencies in the prior art, utilizes optical principle and the method that electronics technology combines, and has proposed a kind of device that reduces solar power system tropical island effect.
A kind of device that reduces solar power system tropical island effect of the utility model comprises convex lens, concavees lens, a sunlight positioning servo tracking system and a set of solar cell power generation system.
Along the direction of propagation of solar light, described convex lens, concavees lens, solar cell power generation system is fixed in sunlight positioning servo tracking system successively, photoelectric conversion unit on solar cell power generation system is arranged in circle, and described photoelectric conversion unit, concavees lens, convex lens coaxially arrange;
Wherein the radius of convex lens is that r will meet:
for the irradiance of the sun,
the conversion efficiency of solar panel converting unit when having barrier, p is cell panel capacity;
The radius of concavees lens is greater than the radius of converting unit; Concavees lens are in one times of focal length of convex lens, and cell panel is in one times of focal length of concavees lens
As preferably, convex lens are that focal length is 60cm, the glass lens that diameter is 100cm;
As preferably, concavees lens are that focal length is 8cm, the glass lens that diameter is 50cm;
As preferably, photoelectric conversion unit arrangement scope is the circular flat of diameter 40cm.
Beneficial effect: the utility model is by dwindling the irradiated area of sunlight, and the area that dwindles the shades such as leaf makes the suffered solar irradiation of cell panel approach homogeneous, stable characteristic, avoid birds droppings, the impact of the veils such as leaf on solar power system, be conducive to extend the useful life of solar cell, eliminate the tropical island effect of cell panel.
Brief description of the drawings
Fig. 1 is the design principle figure that the utility model reduces solar power system tropical island effect;
Fig. 2 is the solar power system schematic diagram of eliminating tropical island effect described in embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated: present embodiment case is with the prerequisite that is designed to of the reduction solar power system tropical island effect that the utility model proposes, but protection range of the present utility model is not limited to following execution mode and case.
As shown in Figure 1, a kind of device that reduces solar power system tropical island effect of the utility model comprises convex lens, concavees lens, a sunlight positioning servo tracking system and a set of solar cell power generation system.
Along the direction of propagation of solar light, described convex lens 1, concavees lens 2, solar cell power generation system 4 is fixed in sunlight positioning servo tracking system successively, photoelectric conversion unit 3 on solar cell power generation system is arranged in circle, and described photoelectric conversion unit 3, concavees lens 2, convex lens 1 coaxially arrange;
The convex lens of using in this device are that focal length is 60cm, the glass lens that diameter is 100cm.Concavees lens are that focal length is that 8cm diameter is the glass lens of 50cm, and the photoelectric conversion unit photoelectric conversion unit arrangement scope of solar panel is the circular flat of diameter 40cm.Solar energy orientation positioning servo tracking system should meet cell panel should face the sun, allows very little error, and the angle of sunlight and cell panel plane can be 85
0-90
0between fluctuation, adopted RY-CPV solar biaxial solar tracking system.
As shown in Figure 2, along the direction of propagation of sunray, place successively convex lens, concavees lens, solar panel, three's circle center line connecting is all vertical with two lens planes and cell panel plane, between convex lens and concavees lens, distance is 45cm-55cm, and distance is 30cm between concavees lens and solar panel, three is fixed in solar energy tracking navigation system with tripod, and concavees lens can regulate back and forth between convex lens and solar panel, along with the difference of solar azimuth, the orientation of the solar energy orientation navigation system detection sun changes and handles servo system makes solar attachment forward the just orientation to the sun to, sunlight imaging is thrown all the time on solar cell panel assembly and concavees lens can be according to the situation of intensity of illumination, distance between manual adjustments itself and convex lens.
In the time that parallel sunray passes through convex lens, due in one times of focal length of convex lens, imaging is the real image dwindling, so sunray converges, project on concavees lens, the light converging becomes parallel rays again, shine directly on solar panel, throw on convex lens with sunray, the real image that shade size also becomes to dwindle in the time projecting on concavees lens, after concavees lens, be irradiated on solar panel, as shown in Figure (1) shows when a branch of sunlight circle spot taking AB as diameter is irradiated on the bull's-eye taking AB as diameter, the total illumination of sunray is W
1, after convex lens, projecting on concavees lens similarly is round taking CD as diameter, the total illumination of sunlight is W
2so sunray irradiates diameter and shunk AB/CD, the illumination of sunlight has strengthened (AB/CD)
2doubly, for hypographous place, light intensity through concavees lens is also eager to excel than the light intensity under direct sunlight under equal conditions, and this kind of method also can be by regulating the relative position of convex lens and concavees lens to regulate the illumination of sunlight, with the variation of the barrier sizes such as reply leaf, also can tackle the seasonal variety of solar illuminance throughout the year simultaneously.
