Abstract
The invention discloses a condensation structure of a solar power generation panel. The condensation structure comprises two fixing supports. A rotary shaft is mounted between the two fixing supports, two photovoltaic power generation panels are mounted on the rotary shaft, one side of one photovoltaic power generation panel is connected with one side of the other photovoltaic power generation panel to form a dihedral angle alpha, and the dihedral angle alpha ranges from 30 degrees to 70 degrees. The condensation structure has the advantages that solar light illuminated on one photovoltaic power generation panel is reflected and then is absorbed by the other solar panel, the illumination intensity of the light on each photovoltaic power generation panel is improved owing to mutual reflection of the light, the light utilization rate is increased, accordingly, the photoelectric conversion rate and the utilization rate of solar energy are increased, and the condensation structure is simple, convenient and practical and is favorable for popularization.
Description
Technical field
The present invention relates to the electro-optical package structure of solar energy, specifically a kind of concentration structure of solar panel.
Background technology
Solar cell is directly light energy conversion to be become to the device of electric energy by photoelectric effect or Photochemical effects.The thin-film type solar cell of photoelectric effect work of take is main flow, with the wet type solar cell of Photochemical effects work also in the budding stage.Usually photoelectric conversion has two kinds of modes: 1 light-heat-electric conversion regime, by the heat energy power-generating that utilizes solar radiation to produce, is generally by solar collector, absorbed thermal power transfer to be become to the steam of working medium, then the driving steam turbine generating.Previous process is light-hot transfer process; A rear process is heat-electric transfer process, the same with common thermal power generation. the shortcoming of solar energy thermal-power-generating is that efficiency is very low and cost is very high, at least than common thermal power station expensive 5～10 times of the investments of estimating it. the solar heat power station of a 1000MW need to be invested 20～2,500,000,000 dollars, and the investment of average 1kW is 2000～2500 dollars.Therefore, can only be applied on a small scale special occasion at present, and extensive utilization is very uneconomical economically, can't compete mutually with common thermal power station or nuclear power station; 2 light-electricity is directly changed, and light-electricity directly this mode of conversion regime is to utilize photoelectric effect, and solar radiant energy is directly changed into to electric energy, and the basic device of light-electricity conversion is exactly solar cell.Solar cell is a kind of device that due to photovoltaic effect, solar energy is converted into to electric energy, it is a semiconductor photo diode, when solar irradiation, on photodiode the time, photodiode will become electric energy to the luminous energy of the sun, generation current.When being together in series or parallel, many batteries just can become solar cell array that larger power output is arranged.Solar cell is a kind of coming novel power supply, has permanent, spatter property and the large advantage of flexibility three. solar battery life is long, as long as the sun exists, solar cell just can once be invested and long-term the use; With thermal power generation, nuclear energy power generation, compare, solar cell can not cause environmental pollution; Solar cell can large, medium and smallly develop simultaneously, and arrives greatly the medium-sized power station of gigawatt, and little of a solar battery group for a family, this is that other power supply is incomparable.
In China, the solar power generation industry also obtains encouragement energetically and the subsidy of government.In March, 2009, the Ministry of Finance announces to intend the large-sized solar engineerings such as solar photoelectric building are subsidized.Current solar energy photovoltaic panel normally is arranged in array and is arranged on spacious part, needs solar energy photovoltaic panel to face sunlight, still, because the irradiating angle of sunlight is changing always, therefore, the electric energy of its generation also changes thereupon, can't transform luminous energy than highland always.
Summary of the invention
The object of the present invention is to provide a kind of concentration structure of solar panel, farthest utilized sunlight, improved electricity conversion.
Purpose of the present invention is achieved through the following technical solutions:
A kind of concentration structure of solar panel, comprise two fixed supports, between two fixed supports, rotating shaft is installed, two photovoltaic generation plates are installed in rotating shaft, one side of two photovoltaic generation plates is connected to form a dihedral angle α, and α is between 30 ° to 70 °.Adopt two photovoltaic generation plates that are connected to form certain angle, after one of them receives sunlight, a part of sunlight can be reflected, be radiated at a sunlight on the photovoltaic generation plate is absorbed by another piece solar panel after reflection, and increase through mutually reflecting the intensity of illumination made on the photovoltaic generation plate, improve light utilization, thereby improved the photoelectric conversion utilance of solar energy.
Be provided with stepping motor on described one of them fixed support, on another fixed support, bearing be installed, the two ends of described rotating shaft are fixed by stepping motor and bearing respectively.Rotating shaft can be rotated under the control of stepping motor, the other end rotates in bearing, thereby drive the photovoltaic generation plate rotates in rotating shaft, change the irradiating angle of itself and light, rotation by the control step motor, make the photovoltaic generation plate follow solar motion daytime, thereby make the photovoltaic generation plate fully receive solar energy, improved the amount that solar energy is converted into electric energy.
Described α is 40 ° to 60 °.Preferably, the angle of dihedral angle α is 40 ° to 60 °, and in this scope, the number of times of its refraction is more, and utilization ratio is also higher simultaneously.
The present invention has the following advantages and beneficial effect:
The concentration structure of a kind of solar panel of 1 the present invention, adopt two photovoltaic generation plates that are connected to form certain angle, after one of them receives sunlight, a part of sunlight can be reflected, be radiated at a sunlight on the photovoltaic generation plate is absorbed by another piece solar panel after reflection, and increase through mutually reflecting the intensity of illumination made on the photovoltaic generation plate, improve light utilization, thereby improved the photoelectric conversion utilance of solar energy;
The concentration structure of a kind of solar panel of 2 the present invention, by the rotation of control step motor, make the photovoltaic generation plate follow solar motion daytime, thereby make the photovoltaic generation plate fully receive solar energy, improved the amount that solar energy is converted into electric energy;
The concentration structure of a kind of solar panel of 3 the present invention, simple in structure, convenient and practical, be conducive to promote.
