- Pulse Width Modulation (PWM) Charge Controllers: PWM charge controllers are the most common type and work by rapidly switching the solar panel’s output on and off to regulate the voltage and current. They are cost-effective and suitable for smaller solar panel systems.
- Maximum Power Point Tracking (MPPT) Charge Controllers: MPPT charge controllers are more advanced and use complex algorithms to track the maximum power point of the solar panel array, ensuring maximum energy harvesting. They are ideal for larger solar panel systems and offer higher efficiency.
