This is because temperature affects the efficiency of a solar panel.
Solar panel temperature controller.
Solar charge controllers are designed to do two main things within a solar power system.
4 stage charging bulk boost float and equalization and temperature compensation increase your battery life and improve your system s performance.
That being said if your solar panels are regularly exposed to rainy or cold weather then a pwm controller s input voltage ratings will be pulled down as the temperature drops.
