Solar, Wind, or Both?

Solar modules receive sunlight during the day, charging the battery bank for use during the night. On cloudy, hazy, or foggy days, very little electricity is produced. Many times. these are the days and nights when the wind blows the best.

Wind power supplements solar when solar is least effective. Solar supplements wind when wind is least effective.

If you use solar only, your batteries will discharge every night and when there are 2 or 3 days in a row of clouds or fog, your batteries may need to be supplemented in order to keep them from going dead.  A deep cycle battery may cycle a thousand times in it's lifetime.  If it goes dead every night, 1000 cycles is only three years of life.  That same battery may last 10 or even 20 years if not allowed to discharge more than 50%.  It is a good idea to keep your batteries charged as they are one of the most expensive components of your system.   

A hybrid system delivers the best of both worlds.

Batteries that are charged both day and night last longer and actually requires less of a battery bank since the time between charges is greatly reduced.  By supplementing your solar with a wind turbine, your batteries will be charged every day by the solar modules and the wind when it is blowing and also at night which will greatly increase the life of your batteries.
