WHAT IS WIND POWER?

Wind energy is collected through wind turbines (basically, these are modern windmills) that harness the power of the wind, kinetic energy, to move turbines (the blades of the windmill) that creates mechanical energy which is then converted into electrical energy on-site through converter ‘boxes’. Turbines today have multiple sizes from smaller micro-turbines suitable for larger residential or commercial properties to larger turbines found at ‘wind farms’.

Benefits of wind energy include

  • Reduces electric bills
  • Durable and reliable
  • New technologies achieve very high efficiency
  • Provides 24 hr./day power, as long as there’s a breeze
  • Contributes to energy independence
  • Can be configured to provide reliable power during utility outages
  • Excellent choice in conjunction with Solar PV system

Like the on-site power generation by solar PV arrays, wind energy is similarly monitored and used by the site and excess electricity is then sold back to the grid, per contractual agreements with the utility.

How Does a Wind Turbine Work?
Do you have a southerly roof exposure and 4-6 hours of unshaded, daily sunlight?

A wind turbine converts kinetic energy from the wind into electrical energy. Typically, a home is served simultaneously by the wind turbine and an electric utility. If the wind speeds are below what’s called cut-in speed (5-8 mph) there is no output from the turbine and all of the power is supplied by the utility. As wind speeds increase, turbine output increases and the amount of power supplied by the utility is proportionately decreased. When the turbine produces more power than the house needs, the extra electricity can be fed back into the electric grid. All of this is done automatically. There are no batteries in a modern residential wind system.
