Description
Technical field
The utility model relates to the electro-optical package structure of solar energy, specifically is a kind of concentration structure of solar panel.
Background technology
Solar cell is the device that directly changes into luminous energy electric energy through photoelectric effect or Photochemical effects.Thin-film type solar cell with photoelectric effect work is a main flow, then also is in the budding stage with the wet type solar cell of Photochemical effects work.Usually photoelectricity transforms has dual mode: 1 light-heat-electric conversion regime through the heat energy power-generating that utilizes solar radiation to produce, generally is by solar collector the thermal power transfer that is absorbed to be become the steam of working medium, and driving steam turbine generates electricity again.Previous process is light-thermal conversion process; The process in back is a heat-electric transfer process; The same with common thermal power generation. the shortcoming of solar energy thermal-power-generating is that efficient is very low and cost is very high; Expensive 5～10 times at least of the investments of estimating it than common thermal power station. the solar heat power station of a 1000MW need be invested 20～2,500,000,000 dollars, and the investment of average 1kW is 2000～2500 dollars.Therefore, can only be applied to special occasion on a small scale at present, and be utilized in very uneconomically economically on a large scale, 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 electric energy, and the basic device of light-electricity conversion is exactly a solar cell.Solar cell is a kind of device that is converted into electric energy owing to photovoltaic effect and with solar energy; It is a semiconductor photo diode; When solar irradiation was to photodiode, photodiode will become electric energy to the luminous energy of the sun, produced electric current.When being together in series or parallel, many batteries just can become solar cell array that bigger power output is arranged.Solar cell is a kind of coming novel power supply, has permanent, spatter property and flexibility three big advantages. solar battery life is long, as long as the sun exists, solar cell just can once be invested and long-term the use; Compare with thermal power generation, nuclear energy power generation, solar cell can not cause environmental pollution; Solar cell can large, medium and smallly develop simultaneously, and arrives the medium-sized power station of gigawatt greatly, and is little of the solar battery group that only supplies a family to use, and this is that other power supply is incomparable.
In China, the solar power generation industry also obtains the encouragement energetically and the subsidy of government.In March, 2009, the Ministry of Finance announces to intend large-sized solar engineerings such as solar photoelectric building is subsidized.Present solar energy photovoltaic panel normally is arranged in array and is installed in spacious part, needs solar energy photovoltaic panel to face sunlight, still; Because the irradiation of sunlight angle is changing always; Therefore, the electric energy of its generation also changes thereupon, can't transform luminous energy than the highland always.
The utility model content
The purpose of the utility model has been to provide a kind of concentration structure of solar panel, farthest utilizes sunlight, improves electricity conversion.
The purpose of the utility model mainly realizes through following technical scheme:
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; Can a part of sunlight be reflected, be radiated at a sunlight on the photovoltaic generation plate and absorbed by another piece solar panel, and increase through reflecting the intensity of illumination that makes on the photovoltaic generation plate each other through reflecting the back; Improve light utilization, thereby improved the photoelectricity trans-utilization rate of solar energy.
Said one of them fixed support is provided with stepping motor, on another fixed support, bearing is installed, and the two ends of said rotating shaft are respectively through stepping motor and bearing fixing.Rotating shaft can be rotated under Stepping Motor Control; The other end rotates in bearing, rotates in rotating shaft thereby drive the photovoltaic generation plate, changes the irradiating angle of itself and light; Rotation through the control step motor; Make the photovoltaic generation plate follow solar motion daytime, thereby make the photovoltaic generation plate fully receive solar energy, having improved conversion of solar energy is the amount of 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 utlity model has following advantage and beneficial effect:
The concentration structure of a kind of solar panel of 1 the utility model; Adopt two photovoltaic generation plates that are connected to form certain angle, after one of them receives sunlight, can a part of sunlight be reflected; Being radiated at a sunlight on the photovoltaic generation plate is absorbed by another piece solar panel through the reflection back; And, improved light utilization, thereby improved the photoelectricity trans-utilization rate of solar energy through reflecting the intensity of illumination increase that makes on the photovoltaic generation plate each other;
The concentration structure of a kind of solar panel of 2 the utility model through the rotation of control step motor, makes the photovoltaic generation plate follow solar motion daytime, thereby makes the photovoltaic generation plate fully receive solar energy, and having improved conversion of solar energy is the amount of electric energy;
The concentration structure of a kind of solar panel of 3 the utility model, simple in structure, convenient and practical, help promoting.
