Whether the assets under inspection are on- or offshore, wind turbines or solar farms, our advanced UAV technology enables full and prompt condition-based assessment by our team of expert engineers and technicians without the need to expose them to any unnecessary conditions, heights or hazards. The drone technology we use at CAN Renewables enables us to get close access to previously inaccessible areas without putting personnel at risk.

What we can do for you


UAV inspection service

Using the latest, high-specification commercial drone technology platform, the DJI Matrice 300 RTK, CAN Renewables’ highly qualified teams of blade technicians or solar electrical engineers pilot the drone for the inspection and undertake remote, condition-based-assessment, dynamic surveys to record and report any internal or external damage. Working with our specialist access team, we can also follow up by physically assessing, repairing and maintaining the asset.

Unrivalled high-performance technology

We undertake UAV surveys using the unrivalled DJI Matrice 300 RTK industrial drone platform; the world’s first drone to offer 55 minutes of flight time along with advanced AI reporting capabilities and six-way directional sensing and positioning abilities.

The fitted state-of-the-art DJI Zenmuse H20T Quad Sensor Solution camera captures everything during the flight survey. Its powerful zoom lens and integrated laser range finder enable the capture of unprecedented high-resolution, full-colour images, high-definition video and radiometric thermal/infrared data for condition assessment of both the internal and external asset structure from either close up or as far as 1200 m away. This enables us fully to assess and report the condition of an asset in fewer flights.

The drone can be equipped with a digital or thermographic camera or a combination, depending on the scope of the inspection required. A digital camera provides visual proof of failures. Thermographic (infrared) inspection is a non-contact and non-destructive inspection method that enables our team to examine large areas for structural defects or weaknesses. We know the elements can often be a challenge, therefore our drone is IP45 rated to protect against water and object ingress.

Reducing costs and downtime, and increasing asset efficiency

Regular inspections of existing assets are vital for safe and sustainable operations with the priority of maintaining optimal asset performance.

CAN Renewables’ UAV inspection service is, compared with traditional telephotography or manual inspections at height, an economic, non-invasive and efficient condition-based-assessment solution. By following a detailed flight planning process for our drone aerial assessment inspection methods, we can quickly and precisely identify potential threats by obtaining both visual and thermal on-site images for analysis and assessment of the asset. These critical inspections can be conducted while operations continue, thus minimising the impact on maintenance costs.

Whether we are surveying solar panels on the ground or at height, or inspecting wind turbines on- or offshore, our efficient and accurate assessments using our UAV technology will identify potential or existing problems that we can follow up with physical access and more detailed inspection and repair, if needed, to get your asset back up and operating with minimal downtime.

Data accuracy and detailed inspection reporting

Our drones are fitted with the most up-to-date inspection payloads; this enables the team to capture all the precision data required in one flight, thus producing high-quality, reliable and repeatable reports and reducing inspection times.

Although the UAV inspection itself is quick, the added value we provide lies in the detailed and accurate analysis and interpretation of the data collected by our qualified and certified team of technicians and engineers, who ensure that nothing critical is overlooked. If required, the inspection report can also include recommendations for leading service and protection solutions and advice on the correct course of action and preventive maintenance deliverables.

Following each inspection, the CAN Renewables team produces and provides a thorough and accurate inspection report, based on the data analysis, using the industry standard of damage categories 1 to 5. Defects are also colour coded in reports for ease of identification. Each report includes the dynamic survey, any images or videos and access to the data portal.

A safer workplace solution

Whether the assets under inspection are on- or offshore, wind turbines or solar farms, the advanced UAV technology enables full and prompt condition-based assessment by our team of expert engineers and technicians without the need to expose them to any unnecessary conditions, heights or hazards. The drone technology we use at CAN Renewables enables us to get close access to previously inaccessible areas without putting personnel at risk.
