Connected LED light to 4.7 V solar panel – but nothing lights up?
I have a setup with a LED and a 330 ohm resistor connected to a 4.7 V, 18 mA solar panel, but when everything is plugged up, the LED doesn’t burn. not even a little. Here’s what is looks like:

Any ideas of what is wrong?
What is the current draw of the LED? Does it mention current on the LED packaging? Some LED components want to draw 30mA.
