Description
Technical field
The solar cell system that the application relates to a kind of solar module and adopts this module.
Background technology
Solar cell has obtained fast development in recent years, and various solar cells have all been obtained remarkable progress aspect technology and commercial two.From the material of battery sheet, the kind of solar cell mainly contains monocrystaline silicon solar cell, polysilicon solar cell, non-crystal silicon solar cell, multi-element compounds solar cell etc.
The photoelectric conversion efficiency of monocrystaline silicon solar cell is to be the highest in the solar cell of present all kinds, and sturdy and durable, and to such an extent as to long service life, but cost of manufacture is very high is can't be by extensively a large amount of and use at large.The cost of manufacture of polysilicon solar cell is lower than monocrystaline silicon solar cell, and material is made easy, saves power consumption, and total production cost is lower, is therefore developed in a large number.Yet, are lower than monocrystaline silicon solar cell in the photoelectric conversion efficiency of polysilicon solar cell and useful life.The principal mode of non-crystal silicon solar cell is thin-film type solar cell, and its technical process is simple, and silicon materials consumption seldom, power consumption is lower, and also can generate electricity at low light condition, but photoelectric conversion efficiency being on the low side and stable inadequately, and the conversion efficiency decay along with time lengthening.The multi-element compounds solar cell refers to not to be the solar cell made with the single-element semi-conducting material can be configured to thin-film solar cells, and its photoelectric conversion efficiency is than the obvious improve of silicon film solar batteries.
From the structure of battery sheet, solar cell can be divided into block solar cell and thin-film solar cells.Arranging the array of solar battery sheet in the cell panel of typical block (being generally crystalline silicon) solar cell.The lead-out wire of these solar battery sheets is connected to the connection line in the terminal box.The cell panel of typical film solar battery module mainly is made of single thin film solar cell sheet, and this battery sheet is connecting connection line in the terminal box by busbar.
Block solar cell and thin-film solar cells are usually configured to the form of solar module.A solar module mainly comprises cell panel and terminal box, is installed on stayed surface such as ground, the roofing by the rail frame system in system applies.In solar energy system, usually solar energy module is carried out series and parallel by terminal box, the output with solar energy module is connected with inverter again,, be transformed into AC energy with the direct current energy that solar module is produced.Like this, the solar module, inverter, rail frame system etc. with terminal box are formed a typical solar cell system.
Inverter is the visual plant during solar energy system is used, and its main function is for the direct current with solar components output changes alternating current into, include in addition MPPT maximum power point tracking (MPPT),
(i.e. electric current and the voltage of the solar module in the combined solar battery system best are so that the maximization output power value.Developed the technology of following the tracks of this best of breed output point in the prior art), functions such as protection, voltage stabilizing, control.In more recent application, a kind of novel inverter-little inverter has appearred.It is different from traditional inverter applications and namely transfers total output of solar module system to alternating current from direct current again after finishing connection in series-parallel between the solar energy module, but directly directly be connected with every solar energy module, make the direct output AC of solar energy module, and the solar energy module of using little inverter also should this be called as interchange (AC) module, is different from traditional direct current (DC) solar energy module.
In actual applications, terminal box often is installed in the back side of cell panel, and little inverter often is installed on the rail frame system or be installed in the back side of cell panel with terminal box.
If inverter is installed on cell panel or the rail frame system, the assembling of solar cell system trouble and consuming time.In addition, inverter is exposed in the external environment, is subject to environmental attack, and this may cause inverter impaired, influences the output of entire system power and useful life.And if inverter is installed in the cell panel back side, inverter can cause cell panel when work local temperature to raise, thereby produces hot spot effect, influence the generating efficiency of solar module, the long-term useful life of reduction solar module.In addition, because the life-span of inverter will lack than solar energy module, when then this kind mounting means can cause changing solar module and little inverter are scrapped simultaneously, increased the use cost of system.On the other hand, use silica gel to paste because inverter is installed in cell backside more, also can't guarantee for the reliability of system.
Therefore, wish the arrangement of inverter in the solar cell system is made improvements, to solve the above-mentioned problems in the prior art.
