Q: In what aspects does the snow retainer clip protect solar panels?
A: The protection of solar panels by snow guard clamp for solar lies in the precise prevention and control of multiple risks, with complex and sophisticated functional details, mainly including preventing snow slide impact, coping with snow loads, and protecting against icicle hazards.
Q: Why does snow sliding damage solar panels, and how do snow guard clamp for solar deal with it?
A: When snow accumulates to a certain thickness on the surface of solar panels without obstruction, it will suddenly slide down like a small avalanche under the influence of temperature fluctuations or wind, with great impact force.
The tempered glass layer of the photovoltaic panel, when subjected to such instantaneous loads for a long time, may develop micro-cracks, which will expand in subsequent cold and heat cycles, eventually leading to glass breakage.
At the same time, the sliding snow may also hit the underlying or adjacent components, causing chain damage.
snow guard clamp for solar, by forming a continuous blocking structure at the edge of the photovoltaic panel, can decompose the sliding force of snow into uniform static friction, allowing the snow to fall off slowly in a “layered peeling” manner, reducing the impact force to less than 1/20 of that in the unprotected state.
Q: What are the characteristics of snow guard clamp for solar in dealing with snow loads?
A: snow guard clamp for solar exhibit the characteristic of “dynamic force unloading” when dealing with snow loads.
When heavy snow causes the snow thickness to exceed the design value, the elastic connectors of high-quality snow guard clamp for solar will produce controllable deformation, allowing 10%-15% of the snow on the surface to slide off first.
This not only avoids overloading of the overall load but also retains most of the snow to maintain the component temperature (low temperature will reduce the photovoltaic conversion efficiency). Tests have shown that this design can increase the average daily power generation of winter photovoltaic systems by 8%-12%.
However, systems with inferior snow retainers or no snow retainer devices either have to shut down for cleaning due to excessive snow accumulation or suffer from bracket deformation due to long-term overloading, which indirectly causes hidden cracks in photovoltaic panels.
Q: How do snow guard clamp for solar protect against the hazards of icicles to solar panels and the surrounding area?
A: The special toothed structure of snow guard clamp for solar can break the continuity of icicle formation.
Traditional photovoltaic panel edges are prone to form icicles 30-50cm long, and the impact force when they fall is equivalent to 40% of that of an iron block of the same volume, which is enough to pierce the underlying equipment or injure people.
snow guard clamp for solar, by changing the flow path of condensed water, control the length of icicles within 5cm, and greatly weaken the connection strength between icicles and components, making them fall off under wind or slight vibration, thus eliminating the risk of icicle falling from the root.
