In a good wind area, a windmill generator can give more power for its cost than solar modules. Both together can give steadier input since a  windmill charges your batteries in storms when there is no sun, and at night as well. But beware of erecting a windmill where the wind is not strong and steady. Your area's wind speed, as well as your immediate terrain, will determine how well the windmill performs. If in doubt, we suggest starting with solar modules, and checking the wind for a year. This will show whether to add either a windmill or more solar modules.

Windmills must mount at least 30 feet above trees and obstructions for 300 feet around.  They need non-turbulent air, where a weather vane holds steady direction.

Charge controls for windmills are different than for solar. All the windmills listed here come with their own charge controls so they can be connected directly to your battery, to work alongside solar charging and generator charging.

The Wind Data Logger is designed to provide an affordable and easy-to-use solution for wind site evaluation and wind generator performance. It easily supports both simple and complex monitoring applications. The Wind Data Logger records wind speed, gust, and direction, as well as the time and
date, temperature (if optional temperature sensor is added), battery voltage, and other important wind parameters. Capable of recording wind speed from up to three anemometers, it is ideal for more complex studies involving multiple wind speed instruments and other sensors.
Recording directly to a Secure Digital (SD™) card provides convenient data downloads
and stores many months of data at 30 second intervals and years of data at longer logging intervals, resulting in fewer trips to retrieve data from the Wind Data Logger. For your convenience, a new file is created and saved to the card each day.
