                    Wind system is more or less similar to PV system.  As it goes, wind is also a form of solar  energy, just an indirect type.  Solar  energy is responsible for both lighting and heating effect on the surface of  the earth.  Due to variable heating on  the surface, pressure difference occurs across the surface due to which wind  blows.
              The only difference between solar power and wind power is  the source of power generation.  It is  wind turbine, imagine a reverse fan, that is responsible for generation of  electric current instead of PV modules.   Power conditioning, storage and conversion is exactly the same as that  in PV system.
              Generally, Wind turbines are rated in voltage and wattage @  rates speed.  Generally, wind output is  rates at 10 m/s or approximately 30 km/hr wind speed.   The starting speed is usually 3m/s or  approximate 10 km/hr.
              To understand the power output, it is important to know the  local wind speed where it is intended to mount the turbine.  Referring to users manual, you should be able  to deduce expected output from the turbine at the given wind speed.  Also, average daily wind hours would help  deduce the power generated by the wind turbine every day.  
              Design of batteries, wind controllers and inverter follows  the same rule as solar system.  Please  refer to the solar system link under design shop for more on this.
