Existing solar-energy photo-voltaic cell system generally comprises photovoltaic terminal box and solar battery sheet; Terminal box generally comprises box body; Be provided with row's conducting bracket row in the box body, thereby form the conduction string through the diode connection between conducting bracket row's the conducting bracket.When connecting solar battery sheet, solar battery sheet is connected in parallel on the diode.The shortcoming that existing this photovoltaic terminal box also exists is: after the illumination crested of irradiation solar battery sheet, the solar battery sheet of crested part is inoperative, and voltage descends very severe.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing solar-energy photo-voltaic cell system, the present invention provides a kind of solar-energy photo-voltaic cell system that when the illumination crested, can reduce voltage drop.
The technical scheme that the present invention solves its technical problem is: a kind of solar energy photovoltaic battery system comprises photovoltaic terminal box and solar battery sheet;
Described photovoltaic terminal box comprises box body; Be provided with first conducting bracket row in the described box body; Thereby form the first conduction string through the diode connection between said first conducting bracket row's the conducting bracket; Also comprise second conducting bracket row; Form the second conduction string thereby also connect through diode between said second conducting bracket row's the conducting bracket, the left end of the left end of the said first conduction string and the said second conduction string also connects the back and is connected negative terminals, the right-hand member and said second that said first conduction is gone here and there conduct electricity the right-hand member of going here and there and connect after be connected positive terminal;
Equal parallelly connected solar battery sheet on the diode of the diode of the said first conduction string and the second conduction string.
Further, the described first conduction string has three conducting brackets, and the described second conduction string has three conducting brackets.
Beneficial effect of the present invention is: establish two row's conducting bracket rows; Respectively at the two ends parallel connection solar battery sheet of the diode of two rows on the conducting brackets; When shade hides the part solar battery sheet; That can reduce solar battery sheet is hidden part as far as possible less, thereby farthest reduces voltage drop.
(4) description of drawings
