How to put this charger into a solar charger
Your current circuit is just a pilot charging circuit, should be coupled with solar charging circuit, and solar modules, this is more trouble
you You can choose the open circuit voltage of 22V solar panels, and then through the Schottky diode directly to the DC section on it. In front of the transformer and rectifier diodes can be removed, more trouble.
Electricity-charging circuit, AC-DC process, so you need to know how much V voltage after AC-DC, and then according to the voltage to choose the appropriate solar panel voltage, such as your DC voltage if it is 14V,
