PWM (Pulse Width Modulation):-
Cost: Low cost.Efficiency: 70%-80%.
Usage: Suitable for small systems with a low voltage difference between solar panels and batteries.
Performance: Less efficient, especially in cold weather or when there is a large voltage difference.
MPPT(Maximum Power Point Tracking):-
Cost: Higher cost.
Efficiency: Up to 98%.
Usage: Ideal for large systems or when there is a significant voltage difference between solar panels and batteries.
Performance: Highly efficient, fully utilizes energy even in variable weather conditions.
Choosing the Right Option:-
Choose PWM:- For small systems, limited budget, and panels with voltage matching the batteries.
Choose MPPT:- For larger systems, significant voltage differences, or areas with cold or variable weather.
