Description
This is an analogue circuit for a battery charger.
Undervoltage the unit is "hard on" then it oscilates around the desired set voltage forming almost a PWM style switching near full charge.
This circuit pulls about 10ma making the losses to this low.
More efficiency could be obtained from the solar panels using MPPT
