Step 1: Cut the pipes.

Cut the pipes into these measurements using the the PVC pipe cutter.

4- 3 1/2 in. pieces
2- 2 1/2 in. pieces
1- 9 in. piece

The width of the pipes that I used is 3/4 in. wide.

Then put the pipes together so it looks like this.

this is a great instructable but you wired the solar panels and batteries inproper. inorder to conect multiple dc power supply you need to do it in a certain way positive to negative. like for example a tv remote, the batteries run into eachother (positive to negative) so for solar panels you simply solder one of one panels negative to the other panels positive after that you are left with a positive and negative wire those would be the output and ground. you connected yours in parrallel which isnt wrong but for a project like this it isnt well sutible. if you connect them in series you will double your output while mantaing the same cap rating. heres a link to a website i just found. http://www.zbattery.com/Connecting-Batteries-in-Series-or-Parallel i didnt mean for my comment to come off as negative feedback because it isnt, i really like this idea! the wind generator is fantastic!
