Wind power generation solar power

Output voltage: refers to the photovoltaic cells under 100 mw/c ㎡ illuminant irradiation, and photovoltaic cells output ends when open the measured output voltage value. Open circuit voltage of pv cells and the incident light is directly proportional to the logarithm of the irradiance, is inversely proportional to the ambient temperature. With battery

output voltage: refers to the photovoltaic cells exposed to 100 milliwatts/c light, on both ends of the pv cells output measured output voltage value when open. Open circuit voltage of pv cells and the incident light is directly proportional to the logarithm of the irradiance, is inversely proportional to the ambient temperature. No matter how much is the area of the battery. Short circuit current: refers to the standard illuminant output short circuit, through the photovoltaic cells on both ends of the current. The short circuit current measurement method is generally on both ends of pv cells connected a variation of less than 1 ohm ammeter in measurement. The maximum output power ( Pm) : the maximum output voltage ( Vpm) X maximum output current ( Ipm) 。 The open circuit voltage ( Voc) : the anode and the cathode is in a state of open circuit voltage. Short circuit current ( Isc) : when the positive and negative short circuit flow of current. Maximum output voltage ( Vpm) : their working voltage of maximum power output. The maximum output current ( Ipm) : the working current of the output of the maximum power. Volt-ampere characteristic curve: refers to the solar energy battery components will receive the conversion of light energy into electricity output current I - V voltage characteristic curve.
