For long-running photovoltaic power age frameworks, the effect of board dust on it ought not be disparaged omega steel profiles. The residue on the outside of the board has the capacity of reflecting, dispersing and engrossing sun oriented radiation, which can diminish the transmittance of the sun, lessen the sunlight based radiation gotten by the board, z profile steel and decrease the yield control. The impact is corresponding to the total thickness of the residue.
The majority of the outside of the photovoltaic board is made of glass. At the point when the wet acidic or soluble residue is appended 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 devastated. 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 an abatement in the power age of the photovoltaic cell. What’s more, harsh, gooey surfaces with cement buildup are bound to aggregate residue 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 weakening of the photovoltaic cell control age.
2. Temperature impact
At present, photovoltaic power plants generally use silicon-based sunlight based cell modules, which are touchy to temperature. As residue collects on the outside of parts, it builds the warmth move obstruction of photovoltaic modules and turns into a warm protection layer on photovoltaic modules, which influences heat dispersal. . After the segment is blocked, it will initiate 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 quickly stacked onto the detour gadget, and the intersection box will produce in excess of 100 degrees of high temperature. High temperature has little impact on the board and intersection enclose the present moment, yet on the off chance that the shadow impact isn’t wiped out and exists for quite a while, it will truly influence the administration life of the intersection box and the board. In industry news reports, the intersection box is regularly singed and impediment is one of the guilty party.
The current and voltage of some battery cells in the sun oriented cell module have changed. Therefore, the result of the nearby present and voltage of the sun based cell module is expanded, in this manner causing a neighborhood temperature ascend on these battery segments. Imperfections in a portion of the battery cells in the sun powered cell module may likewise make the parts 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 gathering melt and decimate the framework lines, bringing about the rejecting of the whole sunlight based cell module. As indicated by industry information, the problem area impact lessens the real existence of sun powered modules by at any rate 10%.
Residue holds fast to the outside of the board, which can square light, retain and reflect light.
The most significant part is the blocking impact of light, which influences the retention of light by photovoltaic boards, hence influencing the productivity of photovoltaic power age. Residue stores on the light accepting surface of the board gathering, which right off the bat makes the surface transmittance of the board decline; besides, the occurrence point of part of the light changes, bringing about uneven proliferation of light in the spread glass. Studies have demonstrated that under similar conditions, the cleaned board get together has a higher yield intensity of at any rate 5% contrasted with the fiery debris gathering, and the higher the cinder aggregation, the more noteworthy the part yield execution corruption.
