2. Translucency: Colorless and transparent PC solar panels can provide excellent transparency and surface gloss, and color panels can block the strongest part of sunlight and soften the transmitted light. The light transmittance is as high as 92%.
3. Thermal insulation: The thermal conductivity (K value) of PC and polycarbonate board is lower than that of ordinary glass and other plastics, which greatly reduces the heat loss. It is used in buildings with heating equipment and belongs to environmental protection materials. However, the heat transfer performance of solar panels made of PC will be greatly reduced because of their hollowness.
4. Impact resistance: PC and polycarbonate are the most impact-resistant thermoplastics. Solar panels made of PC and polycarbonate can maintain good impact resistance for a long time in a wide temperature range, and have the reputation of "unbreakable glass" and "ringing steel". Plastic technology focuses on the research and development of solar panel structure, the impact strength is 250-300 times that of ordinary glass, and the acrylic panel with the same thickness.
5. Dew prevention: Under normal circumstances, when the outdoor temperature is 0℃ and the indoor temperature is 23℃, as long as the indoor relative humidity is lower than 80%, huge fog drops will be generated, which will affect the light transmittance. In the cold areas such as Northeast China, the requirements for fog prevention are very high, and the surface of the plastic solar panel will not be dewed due to special treatment.
