To measure obstacles we use a Leica A8 Disto with laser range finder. The
in-built tilt sensor and camera unit allows accurate and rapid measurement of heights. Locations are recorded to 3 m accuracy using a WAAS enabled GPS. Porosity is recorded using a digital camera and assessed by experts.
The windshelters are used with landform xyz data to predict the variation in wind climate across your site using either simple laminar flow models or xxx.
We email you a pdf report which includes an initial annual energy estimate using our best estimate of local wind speed and local long term wind rose. The estimate accounts for the wind obstacles surrounding your site and is based on your preferred wind turbine(s). The report will propose a suitable location for wind monitoring to accurately measure wind speed, direction and shear. Please note that "best estimates" are notoriously unreliable and are only used to give a qualitative idea of the wind speed.
We will offer you a range of options for measuring the wind climate of your site specifically related to your requirements. Each option has an associated uncertainty on the final results. In general, the higher the cost, the lower the uncertainty.
