For long-running photovoltaic power age frameworks, the effect of board dust on it ought not be disparaged. The residue on the outside of the board has the capacity of reflecting, dissipating and retaining sun z profile size oriented radiation, which can diminish the transmittance of the sun, decrease the sun based radiation gotten by the board, and lessen the yield control. The impact is relative to the aggregate thickness of the residue.
Board residue will effect long-running photovoltaic power age frameworks
1. impediment impact
Residue holds fast to the outside of the board, which can square light, ingest and reflect light.
The most significant part is the blocking impact of light, which influences the assimilation of light by photovoltaic boards, in this manner influencing the proficiency of photovoltaic power age. Residue stores on the light accepting surface of the board gathering, which initially makes the surface transmittance of the board decline; also, the occurrence point of part of the light changes, bringing about uneven spread of light in the spread glass. Studies have demonstrated that under similar conditions, the cleaned board get together has a higher yield intensity of in any event 5% contrasted with the fiery debris get together, and the higher the slag collection, the more noteworthy the segment yield execution debasement.
The majority of the outside of the photovoltaic board is made of glass. At the point when the wet acidic or soluble residue is joined to the outside of the glass spread, the outside of the glass will be disintegrated gradually, which will cause pits superficially, making the light structure a diffuse reflection on the outside of the spread. The consistency of proliferation in the glass is obliterated. The more unpleasant the photovoltaic module spread is, the littler the vitality of the refracted light is, and the vitality really arriving at the outside of the photovoltaic cell is diminished, bringing about a reduction in the power age of the photovoltaic cell. Furthermore, unpleasant, gooey surfaces with glue buildup are bound to collect clean than smoother surfaces. In addition, the residue itself will likewise ingest dust. When the underlying residue is available, it will make more residue aggregate and quicken the constriction of the photovoltaic cell control age.
3. Temperature impact
At present, photovoltaic power plants generally use silicon-based sun oriented cell modules, which are delicate to temperature. As residue gathers on the outside of parts, it expands the warmth move opposition of photovoltaic modules and turns into a warm protection layer on photovoltaic modules, which influences heat dissemination. . After the part is blocked, it will prompt the detour security segment in the intersection box behind it to begin. The DC current of up to 9A in the part string will be immediately stacked onto the detour gadget, and the intersection box will create in excess of 100 degrees of high temperature. High temperature has little impact on the board and intersection confine the present moment, yet on the off chance that the shadow impact isn’t dispensed with and exists for quite a while, it will genuinely influence the administration life of the intersection box and the board. In industry news reports, the intersection box is frequently scorched and impediment is one of the offender.
The current and voltage of some battery cells in the sunlight based cell module have changed. Subsequently, the result of the nearby present and voltage of the sun oriented cell module is expanded, along these lines causing a neighborhood temperature ascend on these battery parts. Imperfections in a portion of the battery cells in the sun oriented cell module may likewise make the segments locally heat during activity. This wonder is designated “problem area impact”. At the point when the hot plate impact arrives at a specific level, the weld joints on the get together dissolve and crush the network lines, bringing about the rejecting of the whole sun based cell module. As per industry information, the problem area impact diminishes the real existence of sunlight based modules by in any event 10%.
