Effect of Temperature on Solar Panel Efficiency |Greentumble
The temperature coefficient tells us the rate of how much solar panel efficiency drops when the temperature will rise by one degree Celsius (1.8 °F). For example, when the temperature coefficient is minus 0.5 percent, it means that efficiency decreases by 0.5 percent for every degree above 25 °C (or every 1.8 degrees above 77 °F).
