Hookup Fan to solar panel...

post #1 of 19
Thread Starter 
Ok so for my exit project for science is wanted to make a little plexi glass box with a fan mounted on the top and a RC car battery with a solar panel. There is only one problem. I cant find a 12v solar panel that can power at least 3 watts. It has to be about 8-9 inches in height and 5-6 inches in its width. Any help guys? I just need one that can be hooked up to power and ground. I want to power everything using molex.

What are the specs of the battery your charging?

Composition, mAh, voltage?

I looked at this and this should fit your bill nicely. It would be easy to hook them up in series. You seem to have a pretty good electrical knowledge should be a piece of cake.

I found this solar panel but i dont know if it would be able to charge the battery
post #9 of 19
What exactly is the goal of your circuit? How do you intend to transition from charging the battery to discharging? Is a quick charge time an important factor?

I want to go from
Solar Panel 12v > Battery to be charged > Fan 12v.
I wanted them all to be 3 way charged with a 3 way molex and a vandal switch.
