Abstract
The invention discloses a basic power supply system for solar cells, comprising a solar cell (1), an automatic control switch (2), a battery (3), an inverter (4), air switches (5), a television (7) and switches (8). According to the basic power supply system for solar cells, the solar cell (1) is independent of a power grid, converts low-voltage direct current into sine wave 220V alternating current through the inverter (4) via the automatic control switch (2), and powers LED lighting lamps (6) and the television (7) which adopt 220V alternating current. Therefore, a set of basic power supply system for solar cells is formed. The system is less in one-time investment and is more economic than a power grid in power supply, can ensure that basic requirements of families in normal lighting and television watching are met in general conditions even if in the case of power outage for various reasons, and is easy to promote.
Description
Technical field
The present invention relates to the basic electric power system of a kind of solar cell
Background technology
It is longer that solar cell has the life-span as a kind of environmental protection new forms of energy, is not subject to the advantages such as regional limits.But at mains supply, very universal (China accomplishes that village of village is logical substantially, logical in every family, developed country is all the more so) situation under convert alternating current to for all family's chargers and illuminalive power-supplies of family with the direct current of solar cell through inverter, not only disposable input is too high, need just can recoup capital outlay for many years from economical and easily angle can not show a candle to and adopt power supply network power supply, this is not obviously a selection that reality is feasible, so this pattern is in the world also just for some exemplary engineerings, even if some developed countries are energetically from policy, fund aspect is helped and is also difficult to promote.
Summary of the invention
The object of this invention is to provide a kind of one-time investment few.More more economical than mains supply, even because a variety of causes has a power failure, still can ensure in the ordinary course of things family's normal illumination and see the primary demand of TV, be easy to the basic electric power system of solar cell of popularization.
For achieving the above object, the basic electric power system of solar cell of the present invention, include solar cell, automatic control switch, storage battery, inverter, television set and switch, the basic electric power system of described solar cell, solar cell is independent of outside electrical network, through automatic control switch, and convert low-voltage DC to sine wave～220V alternating current to the interchange～220VLED lighting adopting and television set power supply by inverter.
The basic electric power system of described solar cell, solar cell daytime through automatic control switch control to charge in batteries, and LED lighting and the television set power supply to family by inverter, automatically turn by storage battery evening and power to LED lighting and the television set of family by inverter.
The basic electric power system of described solar cell, the rated power of selected solar cell is greater than the rated power sum of LED lighting and the television set of Suo Dai family.
The basic electric power system of described solar cell, its every LED lighting and television set are in parallel mutually, and respectively have switch independently to control.
Due to the basic electric power system of solar cell of the present invention only need to family LED lighting and television set realize the most basic guarantee power supply, and account for the most family's charger of family's power supply still by mains supply, thereby only need select low power solar cell, the price of solar cell is 4～5 yuan/watt at present, so containing solar cell, automatic control switch, inverter and storage battery one-time investment are fewer, through budget approximately three years with regard to recoverable investment, solar battery life is 20 years, the period being equivalent to is thereafter not need the flower electricity charge, than more economical by mains supply, the another basic electric power system of solar cell separates with electrical network, even thereby because of earthquake, tsunami, the reasons such as ice damage cause grid power blackout generally still can ensure normal illumination and see TV, thereby it is few to have realized one-time investment, more more economical than mains supply, even because a variety of causes has a power failure, generally still can ensure family's normal illumination and see the basic need of TV, be easy to the object of promoting.
Brief description of the drawings
Below in conjunction with drawings and Examples, the basic electric power system of solar cell of the present invention is further described.
Accompanying drawing is the circuit theory diagrams of the basic electric power system of solar cell of the present invention one family family;
1, solar cell 2, automatic control switch 3, storage battery, 4, inverter, 5, air switch 6, LED lighting 7, television set 8, switch
As shown in the figure: 24V, 200 watts of solar cells 1 connect with the input of automatic control switch 2, storage battery 3 also connects with automatic control switch 2 another inputs, the input of inverter 4 connects with the output of automatic control switch 2, the output of inverter 4 through air switch 5 connect family's 8, each room LED lighting 6 and and television set 7, wherein 6 (1), 6 (2) to select rated power be the LED illuminating lamp tube of 15 watts, 6 (3)～6 (8) to select rated power be the LED bulb of 8 watts, 6 (1)～6 (8) rated voltage is interchange～220V, and respectively there is switch independently to control.The rated voltage of television set 7 is interchange～220V, rated power is 40W, and there is switch 8 independently to control, the basic electric power system of this solar cell realizes daytime by automatic control switch 2 controls and by solar cell 1, storage battery 3 is charged, and power to LED lighting 6 and television set 7 with rated voltage interchange～220V through inverter, automatically turn by storage battery 3 evening and power to LED lighting 6 and television set 7 with rated voltage interchange～220V through inverter 4, so just formed the basic electric power system of solar cell of an a set of family family.
Particularly 5 layers, rural area is more applicable with interior residential building for town and country for the basic electric power system of solar cell of the present invention, taking five floors as example: 1-5 layer 5 family corresponding unit house shared solar cell 1 select 24V1000W just, automatic control switch and storage battery, inverter, still at each family indoor location, are convenient to independent control and are safeguarded.
