    Hi L'eau.Life
    In the meantime you should have some experience with your little 120 mA charger. How did it go? Did the charger had a diode build in? To prevent the battery discharging when the solar panel is in the dark? Unfortunately I just discover that not all solar panels have a diode build in, to prevent the battery from discharging via the solar panel when dark. For that reason I have enclosed an update of the circuit diagram I suggested and has proven to be inexpensive and it keeps your battery charged whatever. My apology, all my solar panels have a diode build in and did not realise that very old panels and some new panels do not have anti discharge diode build in.
