For long-running photovoltaic power age frameworks, the effect of board dust on it ought not be thought little of. The residue on the outside of the board has the capacity of reflecting, dispersing and retaining sunlight based radiation, which can lessen the transmittance of the sun, decrease the sun powered radiation gotten by the board, l profile steel and diminish the yield control. The impact is relative to the aggregate thickness of the residue.
1.Corrosion impacts
A large portion 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 spread in the glass is devastated. The harsher 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 decline in the power age of the photovoltaic cell. What’s more, harsh, thick surfaces with cement buildup are bound to amass dust than smoother surfaces. Additionally, 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 for the most part use silicon-based sunlight based cell modules, which are delicate to temperature. As residue aggregates 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 scattering. . After the part 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 segment string will be immediately 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, however on the off chance that the shadow impact isn’t killed 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. Subsequently, the result of the neighborhood current and voltage of the sunlight based cell module is expanded, in this way causing a nearby temperature ascend on these battery segments. Deformities in a portion of the battery cells in the sun based cell module may likewise make the parts locally heat during activity. This marvel is classified “problem area impact”. At the point when the hot plate impact arrives at a specific level, the patch joints on the get together soften and obliterate the lattice lines, bringing about the rejecting of the whole sun based cell module. As indicated by industry information, the problem area impact diminishes the real existence of sun oriented modules by at any rate 10%.
3.occlusion impact
Residue sticks 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 ingestion of light by photovoltaic boards, therefore influencing the effectiveness of photovoltaic power age. Residue stores on the light accepting surface of the board get together, which right off the bat makes the surface transmittance of the board decline; furthermore, the occurrence edge of part of the light changes, bringing about uneven engendering 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 powder gathering, and the higher the fiery remains aggregation, the more prominent the part yield execution corruption.
