Step 1: Understand your local wind condition

A wind turbine’s performance is highly dependent on the wind resources it receives. When we are selecting a location for a small wind turbine, we always look for locations that provide the best wind resources with higher capacity factors. The rule is simple: The higher the wind speed, the more power generated. The stabler the incoming wind, the smoother the turbine operates.

Understanding your local condition is one of the most essential steps to complete when planning for your small wind turbine. Relevant wind data can help you assess potential power generation performance at your wind site, the stability of electricity supply by wind turbines, and the amount of the resulting financial return. It can also help you select the most suitable wind turbine to install if you haven’t made up your mind yet.


What kinds of wind data do I need to collect?


1. Long-Term Wind Condition Analysis

First and foremost, gather the wind activity data at your chosen wind turbine site continuously for at least 3 months to 1 year. You can do this by setting up an anemometer. However, to acquire accurate information, you need to set up the anemometer at the height of the wind turbine rotor, which can be 10 meters or higher for a small wind turbine.

With an anemometer, you will be able to have a full analysis covering key data such as prevailing wind speed, prevailing wind direction, and incoming wind consistency, as well as other wind characteristics.


2. Long-Term Weather Condition Overview

Secondly, it is always helpful to have an overview of the local weather condition throughout the year even when your small wind turbine is mostly weather-proof. A weather overview provides information about large-scale seasonal wind changes within the region due to storms or other weather patterns. Temperature data can also assist your architectural or engineering experts evaluate their construction plans for the wind turbine.

Always collect your wind and weather data locally.

Always conduct measurements locally

Although some people may refer to the national or regional wind map released by weather authorities to estimate the local wind resource, they do not provide enough insights to local site features. These wind maps cannot include wind speed distribution, direction distribution, turbulence intensity, and other wind activities influenced by surrounding landscape and nearby architectural structures. It is always recommended to set up a local anemometer at the appropriate height to acquire the most precise wind assessment report.


Next Step: Evaluate your location for turbine installation

Once you have enough wind data about your local wind site, you can move on to assessing the location environment and construction regulations, which are closely tied to the installation of a small wind turbine.

Wind Energy - Advantages and Disadvantages

Wind energy brings with it many advantages for the environmant and for our planet. It doesn't require fuel or water, is cost-efficient and causes little pollution. But it also comes with disadvantages, most of them related to the infrastructure necessary for harvesting wind power.

How can wind turbines help to generate off-grid electricity?

The term "off-grid" electricity refers to buildings or communities that operate without being connected to the electric grid. The power that thy consume is usually provided by solar or wind systems. Combining these two into a hybrid system can be a very efficient option.

Onshore and Offshore Wind Energy: A Comparison

Wind farms can be built both onshore and offshore, but they have different advantages and disadvantages. The differences between onshore and offshore wind farms come in four aspects: Cost, Location, Environmental Impact, and Capacity Factor of wind turbines.
