During actual the use, each monocrystaline silicon solar cell 1 bypass diode in parallel, afterwards a plurality of cell device series connection back is formed a line by shown in Figure 1, the top is put EVA (lamellar) and ultraviolet filter glass 5 from top to bottom successively, the bottom is put thermal conductive silicon film and ceramic substrate 6 from top to bottom successively, adds frame fixation behind the press mold.Cooling device is considered heat radiation and cost by design shown in Figure 3 simultaneously for the ease of processing, and cooling pipe 8 and radiator 10 are all made by aluminium alloy.With the top that is welded on cooling pipe 8 behind ceramic substrate 6 surface metalations with 4 reflectors 2, column condenser 3, photovoltaic cell 1 and radiator 7 by combination shown in Figure 1, outside use aluminum alloy frame is fixed and is supported, and reflector 2, column condenser 3 and 1 of photovoltaic cell will carry out sealing and dustproof to be handled.By installation light-sensitive detector 11 shown in Figure 4, shell 12 and shading baffle plate 13 all are made of metal, and inner surface is coated with opaque blacking, and shell 12 and shadow shield 13 all will have certain height.Each detector 11,22 is installed in the central top of support, and controller 29 is installed in by the detector, and the end end that links to each other with detector 11,22 links to each other with motor 25.Each concentration photovoltaic system 21 usefulness support links to each other, be installed on the stepping motor 25 of horizontal direction together with devices such as the detector 11,22 at top and controllers 29, can be when machine operation with the first half support left-right rotation together, motor lower portion is fixed on the metab 27.Whole tracking means is in resting state at ordinary times, has only when timer to begin startup work then, and the wind-force detector signal has the highest weight limit, stops machine operation when recording wind-force automatically after too high; Light intensity detector and clock have second authority, cross when recording light intensity that stop tracking means work automatically and judge whether when weak need be with the tracker homing; Light-sensitive detector has the 3rd authority, when the front judges that can operate as normal the time, according to the signal that detection obtains, motor moves cell panel phase light intensity side automatically, quits work after the light intensity signal intensity on 2 light-sensitive devices 13 is in full accord.Storage battery and power-supply system 26 are installed in the base top, at ordinary times by the photovoltaic cell charging, when tracking means is worked, as the power supply output power of device.
Reach 17% monocrystaline silicon solar cell as Blast Furnace Top Gas Recovery Turbine Unit (TRT) with efficient in the reality, use the column collector lens, the light intensity of gathering has reached 30 times, and high light intensity has improved generating efficiency, makes the efficient of concentrator cell assembly bring up to 22.9%.With respect to traditional Fresnel mirror, it is more even that the column condenser focuses on the back light distribution, is difficult for aging distortion.Hot spot after assembling simultaneously is a linear light strip, only needs the one dimension solar tracking system just sunlight can be gathered on the photovoltaic cell accurately, has significantly reduced the requirement to tracking system.
Between collector lens and monocrystaline silicon solar cell, install four reflector additional, when Blast Furnace Top Gas Recovery Turbine Unit (TRT) breaks down, the light belt that focuses on is not on battery the time, and reflector can reflex to light belt and continue generating on the battery, prevents that simultaneously the high light of assembling from destroying the internal components of Blast Furnace Top Gas Recovery Turbine Unit (TRT).
Each monocrystaline silicon solar cell bypass diode in parallel, when indivedual monocrystalline silicon batteries according to not falling sunlight or break down can not generate electricity the time, diode current flow provides path, the battery that protection can't be generated electricity does not influence the work of other battery simultaneously.The several piece monocrystaline silicon solar cell is formed a line, be connected in series and form the generating element of a strip, and install a ultraviolet ray filter up additional, can prevent that the high-intensity ultraviolet of assembling from influencing the performance of photovoltaic cell.
Monocrystaline silicon solar cell binds on a ceramic substrate with the thermal conductive silicon film, can guarantee that the electric insulation of battery and matrix does not influence heat radiation again.Because can producing very big heat, the high strength sunlight of assembling make the temperature rising of photovoltaic cell influence power generation performance, and general passive radiating mode deficiency so that battery in lower temperature work, therefore on ceramic substrate, install a cover liquid cooling apparatus additional, cooling liquid by circulation can reduce the generating efficiency reduction that temperature rise causes so that the working temperature of battery remains on below 50 ℃.
In order to guarantee that the sunlight vertical incidence improves generating efficiency, concentration photovoltaic system need be installed on the sun tracker, constantly adjust the angle of concentration photovoltaic system.Owing to used the line condenser, can guarantee to focus on all the time on the battery at vertical direction sunlight, only need to use the one dimension sun tracker, make condenser system rotate the tracking sun in the horizontal direction and get final product.
The simple more light intensity comparison method of tracking accuracy height, system that adopted this device realize to sunlight from motion tracking.Record by 2 photosensitive components and parts that are placed in the cavity that container isolates mutually and to shine top light intensity, data are sent into controller.When the data that record when 2 photosensitive components and parts are inequality, illustrate that sunlight has deviation, the flat board of sun tracker moved to the light intensity direction that the direct projection of explanation sunlight enters when the data on 2 photosensitive components and parts are identical, and flat board is parked in existing angle.With the azimuth of a step motor control cell panel horizontal direction, just can guarantee the vertical incidence of sunlight.Because it is very slow that move the position of the sun, the rotating speed of motor design is very low for this reason, and in about 4 hours/week, because the very high power consumption that can reduce motor of rotating ratio, the motor total power consumption is less than 1% of electric power generation cell.Simultaneously detector and controller are set at timing mode, the every start through after a while surveyed once, and all the other times enter sleep pattern, save electricity that can be a large amount of.In order to prevent that high wind from damaging tracker, install the wind-force detector additional, when wind-force increased to a certain degree, motor quit work and reduces up to wind-force.
Outside controller, adorn a light-sensitive detector and clock in addition, when light-sensitive detector records that external sunlight intensity is very weak to be not suitable for photovoltaic battery panel and to work, automatically stop the operation of tracker, record this moment when being evening when clock simultaneously, second day The sun came up waited in the operation that cell panel is automatically reverted to the home position and stop tracker.
