“…In solar panel maintenance, visual inspections 12 could thus be conducted to check for defects in any of the panels. In addition, drone/light unmanned vehicle techniques with infrared cameras could also be instead of ground-based inspection techniques [20][21][22]. Furthermore, pilot and sensor operator inspected visual images can be taken from a height of 10-15m during maintenance in a large-scaled PV system or rooftop system, which could reduce the number of manual tasks required and reduce the amount of time taken to conduct the inspections.…”

“…In the specific application tested, the sampling rate of 1 frame per second was used, because it guarantees a good trade-off between the overlapping required by the post-processing algorithm and the inspection time. The thermal camera had a resolution of 640 × 512 pixels, while the visual camera had a resolution of 4592 × 3448 pixels to guarantee a ground resolution of 10 pixels per centimetre at an average flight height of 10 m [20]. These cameras guaranteed a very large temperature range, from −40°to +135°.…”

“…Energies 2019, 12, x FOR PEER REVIEW 3 of 14 current state of technology is such that the images recorded by the drone are stored in the form of a single sheet, and confirmed by the laboratory or by video shooting [16,17]. The increasing demand for fast inspection speed (while maintaining reasonable accuracy) calls for new tech-savvy approaches, such as unmanned aerial vehicles (UAVs).…”

“…To reduce this problem, recently, some research has used drones fitted with thermal imaging cameras for rapid monitoring of solar power plants [13][14][15]. However, the current state of technology is such that the images recorded by the drone are stored in the form of a single sheet, and confirmed by the laboratory or by video shooting [16,17].…”
