Things to consider when looking into alternative energy. What you will need:

  1. Source of power, either photovoltaic or wind or water.
  2. Charge controller for PV or wind. They are not the same!
  3. Battery to store power for later use.

Wind Power[edit | edit source]

How many volts does it take to charge a 12vdc battery?

  1. The supply voltage for a 12V battery bank is about 16V. This allows charging lead acid to 14.40V (6 x 2.40V/cell) and Li-ion to 12.60 (3 x 4.20V/cell). There are also different charge controllers for different battery types. http://battery university dot com/learn/article/charging_with_solar_and_turbine
  2. An advanced charge controller tracks power by measuring the voltage and adjusting the current to get maximum power transfer with prevailing light conditions. Get a controller with MPPT to make the most of lower power conditions.
