Solar charge controllers can be classified into two main types: pulse-width modulation (PWM) controllers and maximum power point tracking (MPPT) controllers. Pulse-Width Modulation (PWM) PWM solar ...

This Low Dropout Voltage (LDO) solar charge controller uses a simple differential amplifier and series P channel MOSFET linear regulator –their compatibility seems like a marriage made in heaven.

Of course, the charger may be scaled for actual requirements. Oscillographs For the future MPPT solar boost regulator (12V panel to 24V battery) MPPT solar buck regulator (12V panel to 12V battery) ...
