For long-running photovoltaic power age systems, the impact of board dust on it should not be barely cared about. The buildup outwardly of the board has the limit of reflecting, scattering and holding daylight based radiation, which can reduce the transmittance of the Hot dipped galvanized c purlins sun, decline the sun controlled radiation gotten by the board, decrease the yield control. The effect is with respect to the total thickness of the buildup.
1. Temperature sway
At present, photovoltaic power plants generally use silicon-based daylight based cell modules, which are sensitive to temperature. As buildup totals outwardly of parts, it grows the glow move resistance of photovoltaic modules and transforms into a warm security layer on photovoltaic modules, which impacts warmth dispersing. . After the part is blocked, it will start the bypass security portion in the crossing point box behind it to start. The DC current of up to 9A in the portion string will be quickly stacked onto the bypass device, and the crossing point box will deliver more than 100 degrees of high temperature. High temperature has little sway on the board and crossing point encase the present minute, anyway in case the shadow effect isn’t killed and exists for a long time, it will genuinely impact the organization life of the convergence box and the load up. In industry news reports, the convergence box is consistently scorched and hindrance is one of the liable party.
The current and voltage of some battery cells in the sun arranged cell module have changed. Hence, the consequence of the area current and voltage of the daylight based cell module is extended, thusly causing a close by temperature climb on these battery sections. Deformations in a segment of the battery cells in the sun based cell module may in like manner make the parts locally heat during movement. This wonder is grouped “issue zone sway”. Right when the blistering plate effect touches base at a particular level, the fix joints on the social gathering mollify and crush the cross section lines, realizing the dismissing of the entire sun based cell module. As demonstrated by industry data, the issue region effect decreases the genuine presence of sun situated modules by at any rate 10%.
2. Corrosion effects
A huge segment of the outside of the photovoltaic board is made of glass. Exactly when the wet acidic or dissolvable buildup is joined to the outside of the glass spread, the outside of the glass will be crumbled steadily, which will cause pits externally, making the light structure a diffuse reflection outwardly of the spread. The consistency of spread in the glass is crushed. The harsher the photovoltaic module spread is, the smaller the imperativeness of the refracted light is, and the essentialness truly touching base at the outside of the photovoltaic cell is lessened, realizing a decrease in the power age of the photovoltaic cell. Additionally, brutal, thick surfaces with concrete development will undoubtedly gather dust than smoother surfaces. Furthermore, the buildup itself will in like manner ingest dust. At the point when the fundamental buildup is accessible, it will make more buildup total and revive the debilitating of the photovoltaic cell control age.
3. Occlusion effect
Buildup adheres to the outside of the board, which can square light, hold and reflect light.
The most noteworthy part is the blocking effect of light, which impacts the ingestion of light by photovoltaic sheets, accordingly affecting the viability of photovoltaic power age. Buildup stores on the light tolerating surface of the board get together, which immediately makes the surface transmittance of the board decrease; besides, the event edge of part of the light changes, realizing uneven causing of light in the spread glass. Studies have shown that under comparative conditions, the cleaned board get together has a higher yield force of at any rate 5% stood out from the powder gathering, and the higher the searing remains total, the more unmistakable the part yield execution defilement.
