question on solar and transistors

mauried:
What is it that you are expecting the transistor to do?
It wont make the led any brighter, and because there will a small voltage drop across the transistor, the led will be dimmer.

I'm actually not sure lol, just experimenting. But let's say I connected even more together in series, couldn't I do the same setup with the transistor and able to handle devices that require higher current. I'm not sure because I am new to solar panels but will it hurt or damage my solar cells if I hook them directly up to what I am trying to power without a transistor in between? would a mosfet perhaps be a better choice? I do not know. I do also realize that there are manufacture made inverters and charge controllers for solar but I want to learn with basic electronic components.
Thanks for response.
