Why when double deck glass components installed on the roof of the building

Double glass no metal frame components, its working temperature was lower than those of conventional components will be 2 ~ 5 degrees Celsius, high capacity 1% ~ 2%, the reason is that the conventional components of aluminum alloy frame for internal air convection. No border, convection can significantly enhance, cause component

double deck glass components without metal frame, its working temperature is lower than conventional component 2 ~ 5 degrees, high capacity 1% ~ 2%, because of air convection in the frame of the conventional components of aluminum alloy is unfavorable. No boundary, convection will be significantly enhanced, led to the decrease of the component temperature. When the distance between the components and roof installation is very close, less convection, so the double deck glass component is more suitable for installation on the roof of the tilt, in this case, the temperature drop is more obvious. For example, if someone stepped on the double deck glass component on the cell itself is curved, but the degree of the cell itself has not changed. Therefore, cell under tensile and compression strength, especially in the process of stretching, cell is easy to produce the gravity. This is the same as the causes in the technical cooperation period. In addition, during the period of temperature control, power attenuation will be smaller. Temperature coefficient on behalf of the thermal expansion and contraction, temperature cycle, the material will also expand and contract. For symmetric structure mechanics, will have little impact on the battery. We double glass components for the aging test in the laboratory, including high temperature and high humidity, hot and cold cycle, PID and ultraviolet light. 2 times the international electrotechnical commission standard test conditions, uv may be six times. After the experiment, double deck glass components of power attenuation value of 2%, especially the PID, basic is less than 1%. According to test results, double deck glass components of power guarantee period of 30 years, starting from the second year, the annual power attenuation is not more than 0. The power of 5%, compared with conventional components guarantee period of 25 years and 0 respectively. 7%. In general, the double glass components has many advantages, and the market prospect is very broad.
