Abstract
The utility model discloses a crystal silicon photovoltaic module battery piece and novel connection structure of bypass diode, photovoltaic module includes longitudinal arrangement's battery piece A of group and transverse arrangement's the B of battery piece group, parallelly connected bypass diode between the positive negative pole of this photovoltaic module, and the B series connection is organized to two adjacent transverse arrangement's battery piece to parallelly connected bypass diode between these two adjacent transverse arrangement's the B's of battery piece group the positive negative pole, connect in parallel respectively and organize each the bypass diode series connection between the B at adjacent two sets of battery pieces. The utility model discloses with parallelly connected bypass diode between the battery piece of the vertical direction of conventionality, change into at the parallelly connected bypass diode of horizontal direction for photovoltaic module when below battery piece receives the shade and shelters from, only can influence the electricity generation of following battery piece when vertical installation, and all above -mentioned battery pieces can also normal electricity generation, photovoltaic module's generated energy when having improved partial battery piece greatly and sheltered from by the shade, full play photovoltaic module's effect.
Description
Technical field
The utility model relates to the improvement of photovoltaic module cell piece and bypass diode connected mode, taking this to improve, making photovoltaic module when vertically installing, can when edge has certain shade to block, there is certain electric energy to export, improve the energy output of whole photovoltaic system.
Background technology
Photovoltaic module is the capital equipment of photovoltaic generation, and the height of its energy output directly has influence on the output income in whole power station.The mounting means of general photovoltaic module is longitudinally, because longitudinal mounting structure, supporting construction is simple, and old cheap, and installation speed is fast, and cost is low.Generally compare, the more horizontal mounting means of longitudinal mounting structure can save the investment of about 5%.
Cell piece relevant position inline bypass diode in photovoltaic module, when the crested of photovoltaic module one series arm, to be taken as other energy having the photovoltaic module of illumination to produce of load consumption, the position of the photovoltaic module of crested will generate heat, the destruction photovoltaic module that this effect can be serious.Produce to prevent this situation, a bypass diode in parallel between conventional photovoltaic module both positive and negative polarity, when cell piece occurs that hot spot effect can not generate electricity, play bypass effect, the electric current allowing other cell pieces produce flows out from diode, make photovoltaic system continue generating, the obstructed situation of electricity-generating circuit can not be produced because certain a slice cell piece goes wrong.
The front and rear row spacing of photovoltaic module array, generally according between project ground 9:00 in morning winter solstice to afternoon 3:00, front-seat photovoltaic module should not have shade to block to rear row's photovoltaic module, ensures the normal power generation of photovoltaic module; But because in 1 year, the shadow distance of this day of winter solstice is the longest, and other times shadow distance is all short than this day, until the summer solstice, shadow distance is the shortest, and reality is in the afternoon after 3:00, and photovoltaic module still has subregion to have solar light irradiation, part photovoltaic module is blocked by shade, for the cell piece of 60pcs shown in Fig. 1 photovoltaic module, conventional photovoltaic assemblies is, every longitudinally 20 pieces of cell piece bypass diodes in parallel, 60 cell pieces, altogether three bypass diodes in parallel.As long as nethermost cell piece is blocked, see Fig. 2, the group string of three 20 is all influenced, almost makes whole photovoltaic module send electric energy.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art, cell piece in photovoltaic module and bypass diode connected mode are improved, make photovoltaic module when vertically installing, can when edge has certain shade to block, still have certain electric energy to export, improve the energy output of whole photovoltaic system.
The technical scheme realizing the utility model object is as described below:
A kind of crystalline silicon photovoltaic module cell piece and bypass diode new Joining Structure, described photovoltaic module comprises the cell piece group A of longitudinal arrangement and transversely arranged cell piece group B, bypass diode in parallel between this photovoltaic module both positive and negative polarity, it is characterized in that: adjacent two transversely arranged cell piece group B are connected in series, and a bypass diode in parallel between the both positive and negative polarity of the cell piece group B that these adjacent two are transversely arranged, the described each bypass diode be connected in parallel on respectively between two adjacent Battery pack sheet group B is connected in series.
Described photovoltaic module comprises the transversely arranged cell piece group B of cell piece group A and 10 of 6 longitudinal arrangements, adjacent two transversely arranged cell piece group B are connected in series, and a bypass diode in parallel between the both positive and negative polarity of the cell piece group B that these adjacent two are transversely arranged, need 5 bypass diodes in parallel altogether, described these 5 bypass diodes be connected in parallel on respectively between two adjacent Battery pack sheet group B are connected in series.
The utility model improves the connected mode of cell piece and bypass diode in original photovoltaic module, by bypass diode in parallel between the cell piece of conventional longitudinal direction, changes at horizontal direction bypass diode in parallel.This syndeton, make photovoltaic module when vertically installing, the cell piece of (longitudinal inferior portion) is subject to shade when blocking below, only can affect the generating of cell piece below, and all right normal power generation of all cell pieces above, substantially increase the energy output of photovoltaic module time percentage of batteries sheet is blocked by shade, give full play to the effect of photovoltaic module.In addition, photovoltaic module in running, generation dust stratification in various degree, dust stratification generally concentrates on the bottom of whole assembly, before not clearing up, the energy output impact for photovoltaic module is larger, and the utility model effectively can reduce the influence degree of dust stratification for energy output.
