Weather resistance refers to the ability of a material to withstand outdoor weather. (Outdoor climate such as sunlight, hot and cold, wind and rain, bacteria, etc.) The working environment of high temperature and high humidity components is very harsh, some work in tropical areas, solar junction box the daily average temperature is very high; some work temperature is very low, such as high altitude areas , High latitude areas;solar junction box some day and night temperature differences are very large, such as desert areas. Therefore, solar junction box the photovoltaic junction box is required to have excellent high temperature resistance and low temperature resistance.
UV resistance has certain damages to plastic products, solar junction box especially in plateau areas where the air is thin and the UV irradiance is high. Flame retardancy refers to the property of a substance or a material that has been processed to significantly delay the spread of flame.
Heat dissipation: The parts that are easily affected by high temperature in the photovoltaic junction box are the sealing ring and the diode. High temperature will accelerate the aging speed of the sealing ring and affect the sealing performance of the junction box;solar junction box there is a reverse current inside the diode, solar junction box and the reverse current will double when the temperature rises by 10 ℃, solar junction box and the reverse current will reduce the current generated by the component , Affecting the power of the component. Therefore, solar junction box the junction box must have excellent heat dissipation or a special heat dissipation design.
