The purpose of choosing multilayer solar panels is to have good heat insulation, high strength or high load-bearing capacity, and not easy to damage . However, some customers who have previously purchased and installed double-layer PC solar panels have reported that the insulation and strength of the double-layer solar panels are not very good. So is it cost-effective to increase the cost of choosing multi-layer solar panels now? Sunshine board manufacturers are here to analyze with you. 1. The advantages of multi-layer solar panels: Multi-layer solar panels are better than two-layer ones, and they have better insulation and stronger support. 2. Disadvantages of multi-layer solar panels: For rain sheds with arched arcs, the more layers, the greater the impact on the service life, because the greater the force it bears when bending. 3. Cost performance: Due to the large amount of materials, the cost of multi-layer solar panels is much higher than that of double-layer solar panels. If the materials used are not added in proportion to the multi-layer board, the wall thickness of the multi-layer board will not keep up, but it will become thinner and affect the quality of use. Specific analysis: 1. In fact, the service life of the solar panel is the top layer, not the number of layers, so the multi-layer board will not bring much benefit to the service life. 2. In the case of the same material, use the material of the multi-layer board to make two layers, the board wall becomes thicker, and the thicker board wall is the real and beneficial service life, so it is recommended to choose the multi-layer board instead of the thicker board. 3. So under what circumstances should we choose multi-layer solar panels! When the space is too small, the height is too low, and the supporting structure is too small, it is more appropriate to choose a multi-layer board to achieve the effect of sound insulation and heat insulation. Multi-layer solar panels are very useful for these situations. It is the key role!
