Then they're connected to the power inverter, from there the cables to the charge controller. For full step-by-step instructions, check out the website http://www.power55.com.

New Wind Turbine by Aerotecture

Here is a new wind turbine design by Aerotecture, originally designed by a man from the University of Chicago.
