SoDAR (Sonic Detection And Ranging) is a type of remote sensing equipment used to measure the vertical turbulence structure and the wind profile of a location. SoDAR systems operate by transmitting an acoustic pulse into the atmosphere and then listening for the return echo of that pulse to determine wind speed and direction.
There are many benefits to employing SoDAR for wind resource assessment purposes. Arguably the greatest benefit is the ability to measure wind speed up to 200 meters above ground level. These measurements at turbine hub height and beyond are useful by themselves but can also be used to corroborate the shear calculations of nearby met towers. SoDAR units are able to measure the vertical component of wind as well. The systems are mobile and can be moved with relative ease around an entire project area.
SoDAR systems can serve to greatly reduce energy production uncertainty when deployed and maintained correctly. Harness Energy has experience working with both Second Wind Triton and ART SoDAR units.
The entire Harness team is Triton Tier 3 certified by Second Wind. This means we have undergone formal training and have been approved directly by Second Wind to perform comprehensive maintenance and installation services on the Triton.
Harness Energy offers complete SoDAR transport, calibration and commissioning services. We ensure the units are sited properly, free from echo interference, level and securely anchored. Harness Energy closely follows a series of stringent testing and calibration procedures to ensure each SoDAR unit is functioning properly.
