Background technique
It is open that solar photovoltaic battery component is typically mounted on region, sun-drenched area, in long-term use inevitably
The shelters such as leaf, dust are fallen, form shade in assembly surface.Due to the presence of local shades, shielded electricity in component
Pond monolithic becomes load consumption, and other have the energy of the cell piece generation of illumination and fever, form hot spot.Hot spot effect is serious
Destroy solar photovoltaic assembly.In order to solve the problems, such as that hot spot, each battery tandem of photovoltaic module answer a bypass second level in parallel
Pipe, more preferably to protect and reduce inert cell piece number under abnormal condition.Under cell piece tandem normal operation, and
The diode at connection cell piece tandem both ends reversely ends, and no current passes through；And working as in cell piece tandem has Individual cells can not be just
Often when work, bypass diode conducting carries out bypass protection to tandem.
Usually diode is placed in terminal box in the installation of photovoltaic module at present, it in actual use can not be by straight
Sight judges diode state, so that fail battery string can not quickly be found in time, influences entire power station photovoltaic generation power and effect
Rate.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of LED photovoltaics
Component.

Grain and bypass diode, the light receiving plate being covered on the solar battery sheet, LED photogenic granules and bypass diode, it is described too
It is positive can cell piece be equipped with it is multiple, there are two the LED photogenic granules and bypass diode are all provided with, part solar battery sheet, one
LED photogenic granules are serially connected in the first battery strings by conducting wire, and the first battery strings are in parallel with a bypass diode, the remaining sun
Can cell piece, another LED photogenic granules the second battery strings are serially connected in by an other conducting wire, the second battery strings with it is another
A bypass diode is in parallel, and two bypass diodes are connected by conducting wire.
Preferably, the backboard, bypass diode, LED photogenic granules, solar battery sheet, light receiving plate pass through encapsulation bonding
Material package forms encapsulating structure together.
Preferably, first battery strings draw positive terminal, and second battery strings draw negative terminal.

Preferably, the external system includes battery, load etc..
Preferably, 8 solar battery sheets are connected in first battery strings.
Preferably, 8 solar battery sheets are connected in second battery strings.
The beneficial effects of the present invention are in LED solar photovoltaic assembly of the invention, when battery strings fault-free and battery
Concatenated LED photogenic granules of going here and there are lighted, and bypass diode in parallel reversely ends；Bypass diode is positive when battery strings break down
Conducting, non-normal working battery strings are short-circuited, and LED photogenic granules extinguish, then determine the battery strings failure.
Compared with prior art, LED solar photovoltaic assembly structure of the present invention is simple, low in cost, can quickly prepare to reflect
Be not out of order battery strings, and later maintenance is facilitated to overhaul, and can be widely used.Meanwhile in Photovoltaic Building Integration, it can also realize
Night illumination is built, aesthetic effect is reached.
