The effect of photovoltaic board

Spread the love

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 engrossing sun based radiation, which can diminish the transmittance of the sun, decrease the sun based radiation gotten by the board, z profile steel and lessen the yield control. The impact is corresponding to the total thickness of the residue.

1. Temperature impact

At present, photovoltaic power plants for the most part use silicon-based sun oriented cell modules, which are touchy to temperature. As residue aggregates 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 scattering. . After the part is blocked, it will initiate the detour insurance segment in the intersection box behind it to begin. The DC current of up to 9A in the part string will be promptly 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 confine 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 theĀ z profile steel board. In industry news reports, the intersection box is regularly scorched and impediment is one of the guilty party.

The current and voltage of some battery cells in the sun powered cell module have changed. Therefore, the result of the nearby present and voltage of the sun oriented cell module is expanded, consequently causing a neighborhood temperature ascend on these battery parts. 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 classified “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 annihilate the framework lines, bringing about the rejecting of the whole sun powered cell module. As per industry information, the problem area impact decreases the real existence of sun oriented modules by at any rate 10%.

2.Corrosion impacts

The greater part of the outside of the photovoltaic board is made of glass. At the point when the wet acidic or soluble residue is connected to the outside of the glass spread, the outside of the glass will be dissolved 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 a decline in the power age of the photovoltaic cell. Furthermore, harsh, gooey surfaces with cement buildup are bound to amass dust than smoother surfaces. Besides, the residue itself will likewise assimilate dust. When the underlying residue is available, it will make more residue collect and quicken the lessening of the photovoltaic cell control age.

3.occlusion impact

Residue clings 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 assimilation of light by photovoltaic boards, in this way influencing the proficiency of photovoltaic power age. Residue stores on the light accepting surface of the board get together, which initially makes the surface transmittance of the board decline; furthermore, the episode 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 in any event 5% contrasted with the fiery debris get together, and the higher the cinder gathering, the more prominent the segment yield execution debasement.
