Two of my solar garden lights have a solar panel exactly twice the size as yours. They have been outside in the sun all day today charging 2 AA Ni-Cad cells which will power the fading 3-colors LED for a couple of hours tonight.
In the middle of summer the LED is bright for about 8 hours.
Outside in the sun, your small solar panel will have a current of about 15mA at noon now in autumn. All day in the sun will produce about 30mAh. Not much to power two motors.
