Pavana GmbH works according to national and international guidelines on a very high quality level. Our high quality standards were confirmed in the course of an accreditation by the DAkkS.

In the following areas our working method is accredited according to DIN EN ISO/IEC 17025:2018:

• Determination of the wind potential and energy yields of wind turbines incl. Determination of the site quality*
• Execution and evaluation of wind measurements by means of anemometer and LiDAR, including LiDAR - verification, plausibility check of RSD*
• Accomplishment of shadow flicker calculation of wind turbines
• Accomplishment of sound immission calculation of wind turbines**
• Extreme wind assessment
• Determination of the site quality after commissioning***

Here you can find the accreditation certificate
