Abstract
The invention relates to a current grading method of a photovoltaic module. The current grading method comprises the following steps of: firstly, regulating current grades corresponding to different current ranges; measuring working current of each photovoltaic module; placing assemblies with the same current grade according to the tested working current and according to rules; sticking corresponding current grading labels on an aluminum frame; when packaging the assemblies, filling the assemblies with the same current grade into the same box according to the current grading labels on the aluminum frame; and sticking the same current grading label on an outer box. Compared with the prior art, the power loss of the assemblies mounted in the system, caused by current mismatching, can be avoided to the great extent; and the whole output power of a photovoltaic system is improved to the great extent.
Description
Technical field
The present invention relates to a kind of stepping method, especially relate to a kind of photovoltaic module electric current stepping method.
Background technology
At present, the price of photovoltaic module is calculated according to power output.The module testing stepping that most of assembly manufacturer produces all is simply to carry out the power stepping, can only guarantee that assembly satisfies the demand of client aspect power by the gross, in the time of but can not avoiding in the system of being installed to, the current mismatch that single component voltage difference causes, cause the part assembly can not give full play to original power, thus the power stage when whole system can not reach design.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of practical photovoltaic module electric current stepping method for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of photovoltaic module electric current stepping method may further comprise the steps:
(1) different electric current gear corresponding to current range of regulation;
(2) measure the operating current of each photovoltaic module, and according to the operating current that test is arrived, put together according to the assembly of regulation in (1) with the same current gear, and paste corresponding electric current stepping label at the aluminium frame;
(3) during pack, according to the aluminium frame flow point shelves label that powers on, the same case of packing into of same current gear, and paste identical electric current stepping label at outer container.
Described electric current gear is different as required can to arrange different gears.
Compared with prior art, the present invention has avoided being installed to assembly in the system significantly because the power loss that causes of current mismatch, has farthest improved the whole power output of photovoltaic system.
The specific embodiment
The present invention is described in detail below in conjunction with specific embodiment.
Embodiment
