Naturally, wind energy developers are very interested in the energy that can be extracted from the wind, and how this varies by location. Wind is ubiquitous, and in order to make the choice of potential project sites an affordable and manageable process, some indication of the relative size of the ‘wind resource’ across an area is very useful. The wind resource is usually expressed as a wind speed or energy density, and typically there will be a cut-off value below which the energy that can be extracted is insufficient to merit a wind farm development. The best, most accurate indication of the wind resource at a site is through on-site measurement, using an anemometer and wind vane.
Paraye Company is proud to be the main Iranian Renewable Energy Organization (SUNA) contractor to delivers wind stations including masts, measurement systems as well as installation and maintenance for the Iranian wind Atlas. Precise information about the area’s wind potential is essential for installation of a wind turbines planning and with more than twenty years of experience we have successfully installed more than 80 wind masts and 250 Automatic Weather Stations across Iran
Site evaluation Wind stations
The first step in any wind project is the initial site assessment to verify the suitability of the site for planned wind turbines. Site evaluation involves the collection of meteorological data (measurement), processing (calculations) and interpretation. A full report on the wind measurement for 12-24 months is the only real justification for project viability, as it reflects the parameters on which depends turbines productivity. Our measurement systems are equipped with high quality sensors produced by well-known companies according to the IEC 61400 12 1 (Wind Turbine Power Performance Testing 12 2005), MEASNET (Cup anemometer Calibration Procedure 2009-10), ISO 3966 (Measurement of fluid in closed conduits 2008-07) and WMO standards. Our system data logger is a high precision compact and easy to handle data logger and it is a leading product worldwide for meteorological and wind power and solar applications. We can transmit measuring data via PSTN, GSM, GPRS or satellite protocols.
Paraye Company has all the equipment, skills and knowledge to help develop your wind site evaluation and offer services to the highest standards such as IEC and MEASNET. We provide turnkey wind measurement solutions for the wind farming industry including towers, measuring systems, installation and maintenance. Even remote areas, complex terrain or difficult access are no impediments for Paraye to install their meteo masts and deliver accurate data about wind potential on site. Wherever the installation of a wind turbine or an entire wind farm is planned, precise information about the area's wind potential is imperative not only to choose the most suitable turbines but also to calculate the expected energy yield as accurate as possible. Since the amount of energy generated by wind rises with the third power of the wind speed, even minor mistakes in estimating the wind speed have an extreme effect on the actual energy yield. Exact wind measurement directly on site can only be the answer.
Turnkey Wind Energy Assessment:
Paraye Company is ready to provide turnkey site assessment, including wind measurement, using high quality equipment for the wind farming industry including 40, 60, 80,100 and 120 meters towers, measuring systems, installation and maintenance.
Alongside the mast design there is another important part with a high influence on the accuracy of wind data: the measuring system. The higher the accuracy of the data captured by the measuring system the lower the uncertainties and the lower the risk in financing your project.
To keep the uncertainties low we only use high quality equipment and sensors according to the relevant norm IEC 61400. We can offer the highest flexibility in customizing your measurement system according to your specific needs. We can provide a vast range of different sensors and brands to adapt the measuring system to site specific conditions and special needs a custom-made measuring system tailored to your needs.

Wind measurement systems:
All Products of our solutions are carefully designed for the most precise and accurate measurement of wind Masts, measuring systems, as well as all accessories are carefully constructed according to the most recent recommendations of the international norm IEC 61400 to assure the most precise and unaffected measurement possible.
Each part of our mast can be customized to meet even the most extraordinary requests, the highest demands or suit the most challenging environment. Measurement masts for small wind power applications and automatic measurement stations for solar radiation measurement complete the product range of Paraye.
Sensors: Paraye offers all sensors needed for ambitious high quality measurements: first class anemometers with MEASNET-Calibration, wind vanes, sensors for temperature, humidity and pressure.
Data logger: To record the signals provided by the sensors Paraye offers a variety of different data loggers of well-known manufacturers, which are programmed and configured by Paraye according to the specific demands of each project.
Communication via GPRS or satellite: Paraye offers different solutions to communicate with the meteo masts and to transfer the wind data to the customer’s servers if available GPRS will be used, but for remote sites without network connection we developed a communication solution via satellite connection.
Power supply: For autonomous operation even at very remote sites Paraye provides solutions for independent power supply based on solar power.
Masts: From 10 m to 140 m height include data cables, guy wires, set of bolts and ground anchors, specially designed for precise wind measurement according to the international standard IEC 61-400. For energy yield studies, wind potential studies, power curve measurements etc.
Aviation lights: Each Paraye masts can be equipped with aviation lights according to the FAA and ICAO guidelines, a single small light on top of the mast as well as complex lighting on different levels with lights of different intensity.
