Small Solar Panel Kits
Is a 3 volt solar panel with a 6.5 mA broken?
well, I’ve got an old solar panel kit from some relatives of mine. Well, as a kid, you can probably guess that I put in a closed circuit backwards and all sorts of dumb things. well, I tested it with an electrometer and it is capable of giving up to 5 volts, but only 6 mA. I am guessing I fried something because now I can’t generate a small motor the size of your thumbnail. I’m not sure that it’s something painfully obvious, but it doesn’t hurt to ask.
It would help if you told us the size of the panel. Were your measurements made in bright sun?
3 volts x 6.5 mA = 20 mW
The smallest one I found for sale has a power level of 80 mW, 4 times the one you have. It has an area of about 10 cm² or about 1.6 square inches. If your panel is a lot smaller, then that may be normal.
But I think it is damaged.
