Description
Technical field
The utility model relates to new energy field, a kind of house balcony grid-connected photovoltaic system of specific design.
Background technology
Along with the development of photovoltaic industry, parallel network power generation extends to civil area from industrial circle gradually, and the space, residential houses is limited, to the requirement processed of cell panel limited amount is installed.When the installation quantity of cell panel is low to a certain degree, its output voltage step-down seriously restricts the generating efficiency of whole grid-connected system, even can't allow inverter normal boot-strap work in the grid-connected system.When inverter can't be worked, the electricity that the photovoltaic cell board component sends can't normally transform output, caused whole grid-connected system to shut down.
The key that can whole system normally be moved is whether the output parameter of photovoltaic cell board component and the input parameter of centralized combining inverter mate.
The utility model content
The utility model purpose is to provide a kind of house balcony grid-connected photovoltaic system, and it can guarantee the normal operation of electricity generation system, improves system works efficient and then improves energy trans-utilization rate.
In order to solve these problems of the prior art, the technical scheme that the utility model provides is:
A kind of house balcony grid-connected photovoltaic system, described electricity generation system comprises photovoltaic cell board component, centralized combining inverter and balcony mounting bracket, described balcony mounting bracket is installed in the house balcony sunny slope, the photovoltaic cell board component is rack-mount, centralized combining inverter is installed near the house balcony, and photovoltaic cell board component and centralized combining inverter connect by cable and the access electrical network.
Detailed technical scheme is: a kind of house balcony grid-connected photovoltaic system, described electricity generation system comprises photovoltaic cell board component, centralized combining inverter and balcony mounting bracket, described balcony mounting bracket is installed in the house balcony sunny slope, the photovoltaic cell board component is rack-mount, centralized combining inverter is installed near the house balcony, photovoltaic cell board component and centralized combining inverter connect by cable and the access electrical network, the photovoltaic battery panel component count of installing is smaller or equal to 3, and the power of centralized combining inverter is 700 watts; And when the photovoltaic battery panel component count of installing greater than 3 the time, the power match of the power of the centralized combining inverter that disposes and photovoltaic cell board component, described photovoltaic cell board component setting angle can be by the adjustment of balcony support.
With respect to scheme of the prior art, the utility model has the advantages that:
The described house balcony grid-connected photovoltaic system of the utility model, it can regulate the setting angle of photovoltaic cell board component by mounting bracket, and then raising photovoltaic receiving efficiency, centralized combining inverter in the electricity generation system and the gross power of photovoltaic cell board component are complementary, guarantee the normal operation of whole system, guarantee the operate as normal of electricity generation system, improve energy conversion ratio.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the overall structure schematic diagram of the utility model embodiment;
Wherein: 1, photovoltaic cell board component; 2, centralized combining inverter; 3, balcony mounting bracket; 4, cable; 5, electrical network access point; 6, balcony.
Embodiment
Below in conjunction with specific embodiment such scheme is described further.Should be understood that these embodiment are not limited to limit scope of the present utility model for explanation the utility model.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.
Embodiment:
Present embodiment has been described a kind of house balcony grid-connected photovoltaic system, its overall structure as shown in Figure 1, photovoltaic cell board component 1 is installed on the balcony support 3, and balcony support 3 is adjusted the setting angle of photovoltaic cell board component 1 by the support bar length of adjusting self.Balcony mounting bracket 3 is installed in the sunny slope of balcony, centralized combining inverter 2 is installed near the balcony 6, be cascaded between the photovoltaic cell board component 1, and receive on the centralized combining inverter 2, the input of inverter 2 is received on the electrical network access point 5 of electrical network.Photovoltaic cell board component 1 and centralized combining inverter 2 connect and the access electrical network by cable 4.
When the quantity of photovoltaic cell board component 1 is that 3 or 3 are when following, the following photovoltaic battery panel assemblies series connection of 3 or 3 back output voltages are lower, this moment, centralized combining inverter 2 employing power were 700 watts centralized combining inverter, can be so that the whole system operate as normal.
And when the quantity of photovoltaic cell board component 1 be 3 when above, the output voltage after 3 above photovoltaic battery panel assemblies series connection is higher relatively, this moment, 2 of centralized combining inverters adopted common centralized combining inverters, can make the whole system operate as normal.
Above-mentioned example only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection range of the present utility model with this.All equivalent transformation or modifications of doing according to the utility model spirit essence all should be encompassed within the protection range of the present utility model.
