Press During traditional thermographic inspections of rooftop solar fields, there is rarely enough space to crawl under the panels to get straight-on, close-up images.
Instead, technicians climb to the roof and walk the perimeter, scanning the rows of solar panels at an angle, which makes it more difficult to detect anomalies. The data also becomes less reliable because of reflections.
Flying a drone over the roof, and close to each panel, helps reduce the reflections and enables the drone to capture more accurate images
