Abstract
Disclosed is a solar photovoltaic system. The solar photovoltaic system is characterized in that a solar photovoltaic cell is mounted on a roof by support legs, an air flow channel is arranged between the roof and the solar photovoltaic cell, an induced draft fan is mounted in the air flow channel, and a wind cap is arranged at the upper end of the solar photovoltaic cell. The solar photovoltaic system has the advantages that the support legs are arranged on the lower side of the solar photovoltaic cell, so that a sandwich layer can be formed between the solar photovoltaic cell and the roof and is used as the air flow channel, heat is dissipated, the generating efficiency is improved, hot air can be quickly exhausted by the aid of the induced draft fan, and heat of the hot air can be quickly dissipated by the aid of the induced draft fan; the photovoltaic cell is reasonable in mounting position and structural design and is unaffected by the illumination time and the illumination intensity; safety factors such as water resistance of the roof, a structural supporting property and wind resistance are sufficiently considered; redundant electric power can be connected into a power grid, so that the power transmission cost and the power distribution cost are lowered, and the reliability of a power supply facility is improved; and the photovoltaic cell is harmonious with surrounding buildings and is low in operating cost, little in maintenance and long in service life.
Description
Technical field
The present invention relates to technical field of solar, relate in particular to a kind of and the building integrated solar photovoltaic system.
Background technology
At present, solar-photovoltaic technology and theCourse of PV Industry are rapid, photovoltaic generation progressively turns to the future development that generates electricity by way of merging two or more grid systems with the Integration of building power supply from solving backwoodsman electricity consumption and special electricity consumption, the application of solar energy photovoltaic system and architecture-integral, mainly by solar opto-electronic board with light energy conversion be electrical power storage in storage battery, can be used for the illumination of staircase, the illumination of emergency light, the aspects such as control of intellectualizing system.It is permanent and become the most important photovoltaic application of world market that photovoltaic roof electricity generation system is easy to installation, power stability, life-span with it, but the solar opto-electronic board power output has to a certain degree decline with the rising of temperature, causes generating efficiency to reduce.
Summary of the invention
For the solar opto-electronic board power output that overcomes existing photovoltaic system has to a certain degree decline with the rising of temperature, cause the problems such as generating efficiency reduction, the invention provides a kind of crystal silicon solar electricity generation grid-connecting device.
The technical scheme that the present invention adopts for achieving the above object is: a kind of solar energy photovoltaic system, solar opto-electronic board is installed on the roof by supporting leg, is air flow channel between roof and the solar opto-electronic board, and induced draft fan is installed in the air flow channel.
The upper end of described solar opto-electronic board is provided with blast cap.
Solar energy photovoltaic system of the present invention arranges supporting leg at the solar opto-electronic board downside and can make between itself and the roof and form interlayer, as air flow channel, takes away heat, improves generating efficiency, heat can be drawn and taken away to hot-air fast by induced draft fan.The installation site of electro-optical package and reasonable in design are not subjected to the impact of light application time and intensity of illumination; The safety factors such as the support of waterproof, structure on roof and wind resistance have been taken into full account; Unnecessary electric power can be connected to the grid, and to reduce the transmission and disttrbution cost, increases the reliability of power supply facilities; Electro-optical package is coordinated mutually with surrounding buildings, and operating cost is low, the maintenance few, long service life.
Description of drawings
Fig. 1 is the structure chart of solar energy photovoltaic system of the present invention.
Embodiment
The structure of solar energy photovoltaic system of the present invention comprises solar opto-electronic board 4 as shown in Figure 1, and solar opto-electronic board 4 downsides are provided with air flow channel 3, are provided with induced draft fan 2 in the air flow channel 3.Described solar opto-electronic board 4 is tilting, and solar opto-electronic board 4 downsides are provided with supporting leg 5.Air flow channel 3 is tilted to upper setting and is provided with blast cap 1 in the end that exceeds solar opto-electronic board 4 with solar opto-electronic board 4, described induced draft fan 2 be arranged in the air flow channel 3 and the air inlet end towards the low side of air flow channel 3.The setting of supporting leg 5 makes between solar opto-electronic board 4 and the roof 6 interlayer, can be used as air flow channel 3, by induced draft fan 2 hot-air is drawn, and takes away heat, and the temperature of solar opto-electronic board 4 is reduced, and its photoelectric conversion efficiency is improved; Combine with the Ventilation device, the air in the interlayer is introduced air flow channel 3, by airflow circulating, take full advantage of the heat in the interlayer.Affected by the geographical position, when solar opto-electronic board 4 was installed, solar opto-electronic board 4 faces answered Chao Nanlve to the west in principle on the Northern Hemisphere, the Southern Hemisphere should be exposed to the north slightly to the west, and this is because afternoon light is stronger, even mist is arranged the morning, in the afternoon can dissipate, also can receive preferably sunlight afternoon.Certainly, during actual installation, also need to walk for the concrete condition of different regions.Geographic latitude is different. and then 4 of solar opto-electronic boards are also different with the ground angle, and the high latitude area angle is larger usually, and the low latitudes angle is smaller so just to maximally utilise sunlight.
