solar panel help?

We Answered:

The 3v motor probably takes an amp or two, so the panel doesn't have enough current.

Do not get in the habit of measuring voltage on your tongue! Voltmeters are cheap, $10 or less. Do you want to lose sense of taste? Or be unable to speak? $10 is cheap....

Transformers do not increase power, and only work with AC, not DC.

The 12 volts 50mA may be enough to trickle charge the batteries, give it a try.

But get a meter!
