What Windar Photonics does

Windar Photonics is a Danish-headquartered, AIM-listed photonics company (PLC incorporated in the UK; operating subsidiary Windar Photonics A/S in Ishøj, Denmark) that designs and commercializes nacelle-mounted LiDAR wind sensors for wind turbine optimization. The company's proprietary technology — derived from research originating at the Technical University of Denmark (DTU) Risø and protected by exclusive IP rights acquired in 2011 — uses coherent Doppler signal processing with low-cost semiconductor light sources to measure wind direction and speed up to 80 meters in front of a turbine rotor, enabling dynamic yaw alignment. Its product portfolio is organized as a hardware-plus-software platform: the WindEYE 2-beam LiDAR sensor for retrofit asset owners, the WindVISION 4-beam LiDAR sensor with vertical and horizontal plane measurements for OEM integration, the WindTIMIZER plug-and-play integration device, the cyber-safe on-premises Nexus OS software operating system (launched 2024), and the Nexus TPM Turbine Performance Monitoring module (launched 2025) providing ±0.5% accuracy fleet analytics independent of SCADA data.

The company monetizes through a hybrid revenue model: one-time hardware sales of WindEYE and WindVISION sensors, subscription-based software licensing for Nexus OS (with upfront perpetual license options), and integration services delivered through the WindTIMIZER solution. Go-to-market is enterprise sales-led, with regional sales leadership covering Europe, North America, and China, supplemented by distribution partnerships with Vestas Service (signed 2018, driving 25% penetration of the North American Vestas V82 fleet by 2025) and Resolux Group (Brazil, launched 2026). Primary customers are wind farm asset owners, turbine OEMs, and large independent power producers; the company claims 1,600 deployed units and a total addressable market of more than 500,000 wind turbines worldwide. As of June 2026, the company's shares are suspended on AIM pending a forensic investigation into approximately €2.8 million of potentially irregular revenue recognized across 2024 and 2025 with two Chinese customers, with only €85,000 in gross cash at May 31, 2026 — placing the business in a refinancing and governance-restoration phase despite its strong underlying commercial momentum.

Core offering

Windar Photonics designs and manufactures nacelle-mounted LiDAR wind sensors (WindEYE 2-beam and WindVISION 4-beam units), the WindTIMIZER plug-and-play integration hardware, and the on-premises Nexus OS software platform with the optional Nexus TPM monitoring module. Together these are sold as three solution bundles — Optimisation, Monitoring, and OEM — that increase Annual Energy Production by 2–4 %, reduce critical turbine loads by up to 20 %, and provide ±0.5% accuracy performance tracking independent of SCADA for wind farm operators and turbine OEMs.

Product overview

Windar Photonics is a Danish manufacturer of nacelle-mounted LiDAR wind sensors and a globally leading provider of retrofit optimisation and wind turbine monitoring solutions. The product portfolio is organized as a platform-plus-modules architecture centered on the Nexus OS software platform, with the WindEYE (2-beam) and WindVISION (4-beam) LiDAR sensors serving as the primary hardware inputs. The WindTIMIZER integration solution connects LiDAR sensors to any wind turbine control system. Nexus OS provides the cyber-safe on-premises operating system, while the Nexus TPM module serves as the first add-on delivering turbine performance monitoring within ±0.5% accuracy. Solutions are offered as three bundles: Optimisation Solution (WindEYE + WindTIMIZER + Nexus OS), Monitoring Solution (Nexus TPM add-on), and OEM Solution (WindVISION for direct OEM integration).

Products and services

• WindEYE LiDAR Sensor WindEYE is a 2-beam continuous-wave nacelle-mounted LiDAR sensor that measures wind direction and wind speed up to 80 meters in front of a wind turbine, enabling dynamic yaw optimisation. Technical specifications: wind speed range 2–75 m/s, data output 1 Hz (2 Hz optional), IP67 rated, operating temperature -40 °C to +55 °C. Sold to wind farm asset owners and OEMs for retrofit and design-in deployment on any turbine model.
• WindVISION LiDAR Sensor WindVISION is a 4-beam LiDAR sensor with an 18° half-cone angle arrangement that enables simultaneous vertical and horizontal plane measurements, detecting yaw misalignment, wakes, gusts, turbulence, wind shear, and rotor effective wind speed. Sold to wind turbine OEMs as a design-in or retrofit solution integrated directly with the turbine control system.
• WindTIMIZER WindTIMIZER is a plug-and-play retrofit integration hardware solution that converts WindEYE/WindVISION LiDAR signals into the same protocol as legacy wind-sensor signals and forwards them to the turbine controller. It enables deployment on any wind turbine model without modifications to the existing control system, and is sold as a perpetual-license integration solution under multi-year contracts to wind farm operators and OEMs.
• Nexus OS Nexus OS is Windar's cyber-safe, on-premises operating system for the LiDAR-assisted product line, providing a graphical user interface for monitoring wind turbines, optimising yaw alignment, and generating automated performance reports. Deployed entirely on-premises and isolated from external networks, with a modular and upgradeable architecture that supports additional software add-ons such as Nexus TPM. Sold primarily on an annual subscription basis, with optional upfront licences.
• Nexus TPM Module Nexus TPM is a Turbine Performance Monitoring software add-on for the Nexus OS platform. It uses LiDAR-measured wind-speed data to track turbine performance within ±0.5% accuracy, providing unbiased performance metrics independent of SCADA systems, with individual-unit and fleet-wide dashboards for real-time efficiency monitoring and historical benchmarking. Sold as an add-on module bundled into the Monitoring Solution for wind farm operators.
• Optimisation Solution The Optimisation Solution is Windar's core retrofit bundle for wind farm asset owners, comprising the WindEYE LiDAR sensor, WindTIMIZER integration hardware, and Nexus OS software platform. It is installed and integrated with the control system of any model of wind turbine and delivers a 2–4% increase in Annual Energy Production and a reduction in critical loads at high wind speeds by dynamically optimising yaw alignment.
• Monitoring Solution The Monitoring Solution bundles the Nexus TPM add-on module with the Optimisation Solution to deliver unbiased wind-field data (wind speed, direction, wake effect intensity, turbulence intensity, rotational speed, air density) and turbine-performance tracking within ±0.5% accuracy for both individual turbines and entire fleets, enabling data-driven optimisation strategies for asset owners.
• OEM Solution The OEM Solution provides turbine OEMs with a complete LiDAR-assisted optimisation and monitoring package centred on the WindVISION 4-beam LiDAR sensor, integrated directly with the turbine control system. It is available as both a retrofit for the installed base and a design-in (factory-fit) solution for new turbine installations, enabling OEM differentiation on AEP and load performance.
