State three factors of charge controller and pv module considered when sizing?

1. Maximum current and voltage ratings: The charge controller and PV module should be sized to handle the maximum current and voltage output of the PV module to ensure efficient charging and protection against overloading.

2. Efficiency: The efficiency of the charge controller and PV module should be considered when sizing to ensure that the system is able to effectively convert solar energy into usable electricity.

3. Temperature and environmental conditions: The charge controller and PV module should be selected based on the temperature and environmental conditions of the installation site to ensure optimal performance and longevity of the system.
