Description
Technical field
The utility model relates to a kind of workbench, is meant that specifically a kind of insulation division of Crystalline Silicon PV Module improves structure.
Background technology
Solar energy grid-connected photovoltaic system without batteries to store energy, directly through combining inverter, is served electrical network to electric energy through being electric energy to conversion of solar energy.The developing direction of sun-generated electric power has been represented in solar grid-connected generating, is the most attractive energy utilization technology of 21 century.Compare with leaving the net solar power system, grid-connected system has the following advantages:
1) utilize clean, reproducible natural energy resources solar power generation, do not consume non-renewable, the carbon containing fossil energy of resource-constrained, no chamber gas and pollutant emission in the use, harmonious with biological environment, meet sustainable development of socio-economy strategy;
2) generate electricity can feed-in electrical network, be energy storage device with the electrical network, save storage battery, can reduce than the construction investment of independent solar photovoltaic system and reach 25%-45%, thereby cost of electricity-generating is greatly reduced.Save storage battery and can improve the mean free error time of system and the secondary pollution of storage battery;
3) photovoltaic cell component and building perfect adaptation; Not only can generate electricity but also can make physical resources make full use of the multiple function of performance, not only help reducing construction cost as construction material and ornament materials; And the building scientific and technological content is improved, increase the attraction;
4) distributed construction divides on the spot nearby and distributes power supply, gets into and to withdraw from electrical network flexible, has both helped strengthening the ability that war and disaster are resisted in electric power system, helps improving the load balancing of electric power system again, and can reduce line loss
5) can play the peak regulation effect, the networking solar energy photovoltaic system is the focus and emphasis that each developed country of the world competitively develops in the photovoltaic application field, is the main flow development trend of world's solar energy power generating, and market is huge, has a extensive future.
Solar cell power generation system utilizes the photovoltaic effect principle to process, and it is the electricity generation system that solar radiation energy is directly changed into electric energy.It mainly is made up of solar cell array and combining inverter two parts.Be shown in the following figure: daytime is when having sunshine; The electricity that solar cell array sends is delivered directly to electric energy on the AC network through combining inverter; Or the electricity that sun the subject of knowledge and the object of knowledge is sent directly supplies power for AC load through combining inverter, and its system mainly comprises with lower component:
1) solar module: a solar cell can only produce about 0.5 volt voltage, uses required voltage far below reality.In order to satisfy the needs of practical application, need connect into assembly to solar cell.Solar module comprises the solar cell of some, and these solar cells connect through lead.On an assembly, the quantity of solar cell is 36, this means that a solar components approximately can produce 17 volts voltage.The physical location that the solar cell that connects through lead is sealed to is called as solar module, have certain anticorrosion, windproof, hail suppression, rainproof ability is widely used in every field and system.When application needs higher voltage and electric current and single component can not meet the demands the time, can form solar cell arrays to a plurality of assemblies, to obtain needed voltage and current.
2) photovoltaic combining inverter: the equipment that direct current is transformed into alternating current.Because what solar cell sent is direct current, and general load is an AC load, so inverter is indispensable.Inverter can be divided into independent operating inverter and combining inverter by operational mode.The independent operating inverter is used for the solar cell power generation system of independent operating, is independent electric.The solar cell power generation system that combining inverter is used to be incorporated into the power networks is with the electric energy feed-in electrical network that sends.Inverter can be divided into square-wave inverter and sinewave inverter again by output waveform.
