We consider four important steps in planning the installation of an wind-turbine electricity-generation system. The following steps will let you work out, among others, the wind force at your site and your energy consumption, and choose the right components to meet your needs.

The questions asked at each step will guide you to your final choice.

Step 1 | Evaluate the site
Step 2 | Evaluate your energy needs

To determine how much energy you need,
it is essential to answer the following three questions
What is your total annual electricity consumption?
What equipment does the wind turbine system need to operate?
What is that equipment's peak power consumption that the wind turbine system needs to supply?
   
To evaluate your electricity power requirements, you need to know:
For how many hours does each piece of equipment operate?
How much power does each piece of equipment consume?


Here's an example:

It is important to evaluate your needs in terms of anticipated peak consumption in order to determine the size of your wind turbine system.

Your peak power consumption determines the maximum power necessary to meet the demand, if the appliances and equipment powered by the wind turbine system are all operating at the same time. The peak consumption represents the extreme case. But it is essential to know what it is in order to determine your energy needs.

Here's an example: For a stand-alone wind turbine system
