The PC solar panel is commonly used in a hollow two-layer structure. Compared with the three layer and four layer honeycomb rice shaped structure, the material performance is not much different. The only difference is that the four layer honeycomb structure is more solid in thickness and the thermal insulation performance is better when the weight per square meter is increased. Of course, the solid structure is also naturally higher than the two layer structure in the middle air. It is generally used in gymnasiums, natatoriums and other places with more requirements for lighting, thermal insulation.
The thicker the polycarbonate PC sunlight board is, the more layers it has, the better the thermal insulation function, but it is not necessarily the thicker the better. Because the PC board is added with the thickness, the complexity of the scheme is enhanced, and the value is also increasing, it is still necessary to choose the right one.
The thermal insulation of PC solar panel is as high as 49%. The thermal conductivity (K value) of PC board is lower than that of ordinary glass and other plastics, the thermal insulation effect is 7% - 25% higher than that of equivalent glass, and the thermal insulation of PC sunlight board is 49% higher. Therefore, the heat loss is greatly reduced. It is used for the construction of heating equipment and is an environmental protection material.
Here we will introduce and compare the advantages and disadvantages of multi-layer sunlight board and ordinary two-layer sunlight board:
1.Advantages of multi-layer solar panels: more layers, better sound insulation and heat insulation, and stronger support than two layers. Disadvantages of multilayer board: For the canopy with arch radian, the more layers of board, the greater the impact on the service life, because it bears more force when bending.
2. Cost comparison: The cost of multi-layer solar panels is much higher than that of two-layer solar panels due to the large amount of materials used. If the materials are not increased according to the proportion of multilayer panels, the thickness of the seven layer solar panels will not keep up, but will become thinner, which will affect the quality of use. In fact, the service life of the sunlight plate depends on the upper layer rather than the number of layers, so the multilayer plate does not bring much benefit to the service life.
3. Under what circumstances is it better to choose multilayer boards? When you are working on the daylighting roof, the keel density is too high, the purlin spacing is too large, or when it is necessary to increase the hardness of the plane and isolate noise for indoor facade partition, the use of multi-layer sunlight panels can play a very important role in these cases.
