Through a combination of drone-based and ground-based RGB and thermal data acquisition and data analysis, Geo-4D can quickly perform a high-level screening assessment of solar farm panel defects.
The process comprises the acquisition of aerial RGB imagery and radiometric thermal imagery data, along with ultra-high resolution ground-based RGB imagery.
The aerial RGB data are used to build a 3D model of the site, whilst the thermal data highlights any thermal anomalies that are often related to malfunctioning solar modules. The ground-based imagery are then used to provide additional information on defects such as fogging, cracks, debris and bird droppings.
Once various defects are identified, they are mapped, linked to panel serial numbers, and uploaded to a web-based portal.
In the web-based portal, the 3D model of the site can be viewed, individual solar panels and identified defects reviewed, and defect information exported.
