No, anything below 15W will not overcharge a 12V battery.

No, a solar battery charge controller is only needed for panels of 15W or greater.

A trickle charger is designed to slowly increase a battery’s voltage, offsetting any natural decrease. The actual time to charge a battery is governed more by the size and condition of the battery than the trickle charger.

To measure the voltage of the panel, use a voltmeter. The open-circuit voltage reading should be between 16 and 25 volts in full sun (not connected to the battery).
