ZX Lidars

ZX Lidars (formerly ZephIR Lidar) provides hub height and turbine mounted wind measurements for wind energy and meteorological applications onshore and offshore with leading wind Lidar products, ZX 300, ZX 300M and ZX TM. With more than 10 million hours of operation in the field and over 1000 deployments (and counting) we have pioneered the use of Lidar in the wind industry, with many world firsts including upwind measurements from a turbine nacelle, turbine wake studies, offshore deployments both fixed and floating, an industry-accepted validation process, re-financing and re-powering a wind farm, technology accuracy demonstration in a wind tunnel and total project financing. ZX 300 is used for remote wind profiling extensively through the pre-planning / scoping, planning, development, construction and operational phases of a 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. ZX 300M takes your wind measurements offshore both of fixed and floating platforms - it is the industry standard Lidar offshore available on all commercial floating platforms and suitable for integration in all fixed platforms. ZX TM is mounted in the spinner / on the nacelle or hub of a wind turbine generator in horizontal mode for yaw misalignment, turbine calibrations, End of Warranty inspections, power curve measurements (absolute and relative), R&D projects and full turbine control. Each and every system is validated either at the IEC compliant UK Remote Sensing Test Site or against a Golden Lidar both in accordance to a industry-accepted process. DNV GL considers ZX 300 and ZX 300M accepted for use in bankable / finance-grade wind speed and energy assessments with either no or limited on-site met mast comparisons in benign conditions.
