PV output temperature characteristics of the temperature rise will affect PV open circuit voltage drop, short-circuit current is a slight increase in PV Merchants, with photovoltaic junction temperature rises PV investment cooperation, the maximum output power declining PV , the efficiency decreases as the temperature rises, i.e., the photovoltaic cell having a negative temperature coefficient. For commonly used for silicon and polysilicon, as the temperature increases the voltage, fill factor FF and efficiency have different degrees of decline. Overall, when the temperature rises rated power output of photovoltaic cells also declined slightly, ambient temperature level will have a direct influence on the maximum output power Hing volt battery. PV photovoltaic products requirements (1) Waterproof, hail, wind. Usually solar panels using glass packaging, aluminum alloy frame packaging, can effectively resist hail, install electricity cooperation with the metal bracket PV join, can withstand more than 10 winds. (2) sunscreen, antifreeze. Generally have ventilation, heat the window, in order to facilitate the battery cooling. For particularly cold winter areas, battery use of anti-coagulated gel batteries photovoltaic solar power investment _ TIANHUI (certified) _ Jingzhou photovoltaic provided by Wuhan days Hui Technology Co., Ltd. giant.
