ZephIR 300 - Onshore Wind Lidar
Continuous wave wind lidar
ZephIR 300: Hub height wind measurements reduce the risk of, and increase the value of onshore wind energy projects.
Onshore wind lidar measurements typically deliver a £320,000 increase on the value of a project through more accurate Annual Energy Prediction (AEP) when compared to a 80m met mast on a 20 MW onshore wind farm – The Ecofys position on LiDAR use.
ZephIR 300 wind lidar is used extensively through the pre-planning / scoping, planning, development, construction and operational phases of an onshore wind energy project in combination with short met masts and tall met masts and associated cup anemometers, roaming during site-prospecting, stand-alone in replacement of a met mast and as a fixed reference control mast.
ZephIR Lidar applies more than a decade of experience in wind energy to ensure ZephIR 300 and ZephIR DM wind lidars can be utilised effectively at every stage of your wind energy project – from pre-planning through to re-powering – both onshore and offshore.
