A wind turbine can provide the perfect complement for an off-grid solar electric system, since the wind might be blowing during the night or in cloudy weather when your solar array is not producing much power. Site selection is an important factor for this type of system, since the wind resource must be adequate to justify your investment.

There are now grid-tie wind turbines available that operate the same way as a grid-tie solar system, providing power to you home or spinning your meter backwards as a credit for later use.
