Description

3 D condenser of multilayer light-volt electric power generation
Technical field
The present invention relates to a kind of photovoltaic power generation apparatus, particularly a kind of 3 D condenser of multilayer light-volt electric power generation belongs to technical field of solar utilization technique.
Background technology
Solar energy is a kind of regenerative resource of cleanliness without any pollution, and is inexhaustible; fully development and use solar energy not only can be saved exhausted day by day conventional energy resource; alleviate severe shortage of resources problem, but also can reduce pollution, the human biological environment of depending on for existence of protection.In numerous solar utilization techniques, solar photovoltaic technology has realized being electric energy with conversion of solar energy directly, it is a kind of mode of utilizing of most convenient, it have safe and reliable to operation, need not fuel, noiseless, pollution-free, can utilize on the spot, advantage such as working service is easy, scale is changeable, thereby be subjected to the attention of countries in the world.
Though solar energy power generating has lot of advantages, in the evolution of photovoltaic generation, use cost is too high to be its key factor of applying rapidly of restriction always.One of its major reason is: the semi-conducting material that is used to produce solar cell costs an arm and a leg, and consumption is big, and causing with the solar cell is that the cost of the photovoltaic generating system of core is difficult to reduce significantly.
Conventional photovoltaic generating system generally is with the solar cell fixed installation, holds at high price, and is difficult to apply rapidly.The electric current of exporting under certain condition according to solar cell is directly proportional with the intensity of illumination of acceptance and increases and don't as for the feature that influences the photovoltaic cell life-span, people begin one's study and adopt optically focused and tracking technique, hope reduces the consumption of solar cell under the situation that obtains same electric energy, and the cost of the tracing collection that increases is equivalent to replace with common materials such as metal glass the semi-conducting material of costliness far below the cost of the solar cell of being saved.States such as Germany, the U.S., Spain, Australia have all developed various light gathering photovoltaic power generating systems such as Fresnel Lenses optically focused, reflecting condensation respectively, the shortcoming of existing refraction optically focused is that light intensity uniformity is relatively poor, transmitance is difficult to improve, manufacturing cost is higher, the shortcoming of large-scale parabolic reflector optically focused is that the parabolic reflector manufacture difficulty is big, cost is higher, and speculum is broken easily, the whole windproof poor performance of mechanism.It is not obvious that these all cause the whole system cost performance to improve, and makes the advantage of light gathering photovoltaic power generating system be difficult to embody.Up to the present, only there is the light gathering photovoltaic power generating system of a small amount of test, exemplary in nature to put into operation.
In recent years, almost the speed increment of China's solar photovoltaic assembly output to be doubled every year, but the level of solar-photovoltaic technology development and utilization also lags behind developing countries such as India, Brazil not only far below developed country.Although there are good solar energy resources and photovoltaic cell manufacturing capacity in China, but the integral level of photovoltaic industry and developed country also have very big gap, the one, the production dependence on import of the employed crystalline silicon raw material of solar cell, raw material is in short supply, at present and even very long from now on one period, the space that cost descends is less, and the 2nd, solar energy photovoltaic system is used also seldom.
Summary of the invention
The object of the present invention is to provide a kind ofly be easy to make, with low cost, cost performance is high, have than high reflection mirror utilance, larger 3 D condenser of multilayer light-volt electric power generation.
For achieving the above object, technical solution of the present invention is:
The present invention is a kind of 3 D condenser of multilayer light-volt electric power generation, and it comprises solar cell module array, the support of solar cell module array is installed, plane reflection lens array, plane mirror installation frame, the device that rotates from the motion tracking sun; The described device that rotates from the motion tracking sun is formed by driving plane reflection the cell mount drive unit that rotates and the photoelectric sensor and the treatment circuit that receive sunray; Described solar cell module array is made of two-layer solar cell panel assembly at least, and multilayer solar panel is arranged in the top of plane mirror longitudinally, at interval.
Described support is arranged on the plane mirror installation frame center line, and its lower end is fixed on the plane mirror installation frame; Described multilayer solar panel longitudinally, rack-mount and be positioned at the top of plane reflection lens array at interval, relative with the plane reflection lens array.
Described every layer solar cell board component is made of two row solar cell panel assemblies of symmetry; Described plane reflection lens array is divided into many groups, and symmetry is installed in speculum installation frame center line both sides.
Two row solar cell panel assembly symmetries of described symmetry are installed in the both sides of support.
The corresponding one group of plane mirror of described every row solar cell panel assembly.
Described every group of plane mirror is made up of 3 row plane mirrors at least.
After adopting such scheme, the present invention has the following advantages:
(1) because solar cell panel assembly multilayer symmetry of the present invention is installed in the both sides of carriage center line, every layer solar cell plate is different with the setting angle of support, reflection mirror array is divided into many groups, symmetry is installed in frame center line both sides, flat glass speculum utilance is greater than 90%, especially under existing monocrystalline silicon battery plate temperature capacity, the optically focused ratio that is particularly suitable for about 3 times requires.
(2) because the multi-level cell panel of the present invention is only installed a tracker, saved manufacturing cost, make that the present invention is simple in structure, be easy to make, with low cost, cost performance is high.Optically focused suits to be applied to help applying of photovoltaic generating system in the solar photovoltaic generation system of different scales than carrying out appropriate design according to the intensity of sunshine of the local sun.
(3) because the present invention is a symmetrical structure, not only carefully and neatly attractive in appearance, and its frame rack structure reserves naturally and wears the wind neutral gear more greatly, and reflection mirror array also forms suitable slit, has significantly strengthened the wind resistance of system.
(4) because the solar module plane of illumination is settled, thereby can avoid dirt such as dust on plane of illumination, to pile up down, can not form hot spot, thereby avoid occurring tropical island effect, can prolong the life-span of solar module.
In sum, the present invention compares with fixed type photovoltaic power generation system, be easy to manufacturing, with low cost, increased the solar light irradiation intensity that solar panel is accepted, obtaining under the same electric energy situation, the consumption of solar cell only is the part of fixed photovoltaic generating system, and increases the cost of the cost of tracing collection mechanism far below the solar cell of being saved, therefore significantly reduce overall cost, improved cost performance.Concentrator rotates from the motion tracking sun by photoelectric sensor, electric-control system and drive unit, guarantees that the sunray of real-time change and concentrator remain certain position relation.Thereby guarantee respectively to organize on the framework level crossing sunray is reflexed on the cell panel on the support equably, realize the several times light-focusing function.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
