Yingli 295w single crystal solar panel photovoltaic power generation

  Solar panel module is a common component in photovoltaic power generation system and an important component
Because this product is a precision product, many factors can affect the performance of this product
This paper mainly makes a brief description of the impact of temperature changes on solar panel components
(1) temperature coefficient of short-circuit current Ti: generally 0
04%/ ℃～ 0
08%/ ℃, indicating that the output current of battery module will increase by 0
04% ～ 0
08% when the temperature increases by 1 ℃
(2) open circuit voltage temperature coefficient Tu: generally -0
3%/ ℃～ -0
5%/ ℃, Henan Yingli PV module is a negative temperature coefficient, which means that the output voltage of the battery module will decrease by 0
3% ～ 0
5% every 1 ℃ temperature rise
It can be seen that the output voltage is inversely proportional to the temperature
The solar light is good, the temperature is low, and the power generation is relatively high
(3) power temperature coefficient TP: generally -0
4%/ ℃～ -0
6%/ ℃, which is a negative temperature coefficient
It indicates that the output power of Henan Yingli PV module will decrease by 0
4% ~ 0
6% when the temperature increases by 1 ℃
