Wind turbine payback period

The size of a wind turbine can be decided based on the energy demand profile of your site. Typical size turbines range from 100kW to 2MW in size. The higher your business’s electricity bills that you offset by using self produced electricity the better the payback. Large scale systems usually give the quickest payback and payback as low as a few years is achievable. To ensure you reach the payback period you will need to install quality equipment.
