PC solar panels are commonly used with a hollow two-layer structure. Compared with the three-layer and four-layer honeycomb m-shaped structure, the material performance is not much different, but the four-layer honeycomb structure is stronger and thicker, and the heat insulation performance per square meter is increased It is more superior. Of course, it is sturdy and naturally taller than the hollow two-story structure. It is generally used in places such as gymnasiums and swimming pools that require more lighting and heat insulation.
The thicker the thickness of the polycarbonate PC solar panel, the more the number of layers, the better the heat preservation function, but it is not necessarily the thicker the better. Because the PC sheet is added with the thickness, the complexity of the solution increases, and the value also increases. Choose the right one.
The thermal insulation of PC solar panels is as high as 49%. The thermal conductivity (K value) of PC board is lower than that of ordinary glass and other plastics, and the heat insulation effect is 7%-25% higher than that of counterpart glass. The heat insulation of PC solar board is as high as 49%. Thus, the heat loss is greatly reduced, and it is used for the construction of warm equipment and is an environmentally friendly material.
Then we are here to introduce and compare the advantages and disadvantages of multi-layer solar panels and ordinary two-layer solar panels:
1. The advantages of multi-layer solar panels: more layers, good sound insulation, good heat insulation, and stronger support than two layers. Disadvantages of multi-layer panels: For rain awnings with arched curvatures, the more layers of panels, the greater the impact on the service life, because it bears greater force when it is bent.
2. Cost comparison: The cost of multi-layer solar panels is much higher than that of two-layer solar panels because of the use of more materials. If the materials used are not increased in proportion to the multi-layer panels, the wall thickness of the seven-layer solar panels cannot keep up. On the contrary, thinning affects the quality of use. In fact, the key to the service life of the solar panel is the upper layer, not the number of layers, so the multi-layer board does not bring much benefit in the service life.
3. So under what circumstances is it better to choose a multilayer board? When you are constructing a daylighting roof, the keel density is too large, the purlin spacing is exaggerated, or when it is used indoors for facade partitions to increase the hardness of the plane and isolate the noise, the use of multi-layer solar panels can be used for these situations. Very critical role.
