Solar panel rainwater diversion accessory functions
During the daily use and maintenance of solar panels, the problem of rainwater accumulation is easily overlooked, and a small rainwater diversion plastic accessory can effectively solve this hidden danger. This article will conduct a detailed exploration around the core functions and specific functions of this accessory, dismantle its important value in the photovoltaic system, and help everyone fully understand its use and significance.
Core basic functions: How to drain water efficiently and prevent water accumulation?
Even if the solar panel is designed with an inclination angle, water accumulation areas will still form at the frame due to water surface tension. Long-term water accumulation will cause a series of hidden dangers. The core and basic function of the diversion accessories is to solve this problem and ensure that the surface of the photovoltaic panel is dry.
Break tension and guide quickly
Through special structural design, the diversion accessories can effectively destroy the surface tension of water, allowing rainwater and cleaning water to flow out quickly along the preset diversion channels, completely clearing the water accumulation on the lower edge of the photovoltaic panel and in the gaps between the frames, and avoiding hidden dangers caused by long-term accumulation of rainwater.
- Destroy the water surface tension, break the deadlock of accumulated water, and accelerate the drainage of rainwater
- Targeted solution to the problem of water accumulation and dead corners on the borders and lower edges of photovoltaic panels
- Adaptable to different rainfall scenarios, efficient guidance and drainage can be achieved even with light rain
Adapt to low-tilt scenes
In distributed power stations with small inclination angles of photovoltaic panels such as colored steel tile roofs, conventional drainage effects are poor and rainwater tends to remain on the panels. Diversion accessories can significantly enhance the diversion efficiency. Even if the inclination angle is small, it can guide rainwater to drain out in an orderly manner and avoid residual water accumulation.
Core efficiency-enhancing functions: How to prevent dust accumulation and hot spots to increase power generation?
Diversion accessories can not only solve the problem of water accumulation, but also indirectly improve the power generation efficiency of solar panels, reduce power generation losses, and enhance the efficiency of photovoltaic systems. They are key accessories for increasing power generation at low cost.
Avoid “mud belt obstruction” and reduce power generation losses
Stagnant water will trap dust and sediment in the air. After the water evaporates, a stubborn "mud belt" will be formed on the lower edge of the photovoltaic panel, blocking the light-receiving surface and causing a decrease in power generation. The diversion accessories can take away floating dust simultaneously during drainage, preventing the formation of mud strips from the source.
- Drainage simultaneously takes away floating dust and prevents the formation of mud strips
- Reduce annual power generation loss due to shading (can be reduced by more than 5%)
- Keep the light-receiving surface of photovoltaic panels clean and ensure stable power generation efficiency
Core protection functions: How to prevent corrosion and leakage, and extend the life of the system?
Long-term water accumulation not only affects power generation, but also causes corrosion and damage to photovoltaic modules, brackets and roofs. By eliminating hidden dangers of water accumulation, diversion accessories achieve all-round protection and extend the overall service life of the photovoltaic system.
Protect the frame and bracket and delay corrosion
Long-term water accumulation will corrode the aluminum alloy frame and bracket connection points of photovoltaic panels, causing electrochemical corrosion and shortening the service life of components and brackets. After the water diversion accessories are eliminated, the risk of corrosion can be greatly reduced and the core structure of the component can be protected.
Avoid the risk of roof leakage
If accumulated water penetrates into the gap between photovoltaic modules and the roof, it will cause problems such as roof leakage, electrical short circuits, and even corrode the roof structure, causing safety hazards. Diversion accessories guide rainwater to drain out in an orderly manner to avoid rainwater backflow and protect the electrical safety of roofs and power stations.
- Prevent rainwater from penetrating into the gaps between components and roofs, and eliminate hidden dangers of water leakage
- Protect the electrical system of the power station to avoid short circuit faults
- Reduce roof structure corrosion and extend roof service life
Conclusion
To sum up, although the solar panel rainwater diversion accessories are small in size, they are indispensable "invisible protection and efficiency components" in the photovoltaic system. Its core function is to efficiently guide and drain rainwater and eliminate hidden dangers of water accumulation. At the same time, it protects the safety of photovoltaic modules and roofs by preventing dust accumulation, hot spots, and corrosion, extending the life of the system, increasing power generation, and reducing operation and maintenance costs. It is recommended that when installing photovoltaic power stations, priority should be given to high-quality water-conducting accessories with strong adaptability and good weather resistance to give full play to their practical value.
