Thermal infrared surveying is a great way to commission solar installations in-situ. After analyzing and commissioning over four (4) gigawatts of solar panels in the past eight years, we have figured out what works and more importantly - what does not work.
Solar installations are not all the same. Before planning a site visit, we take into account the size and layout of the field, the types of panels, how the panels are wired, and then the best timing of the survey. Correct timing of the survey is the most important factor because the amount of solar insolation is critical to successful testing. To successfully accomplish the testing under good conditions, many factors need to be known or predicted with accuracy. These include the layout of the field, the ambient conditions (such as rain, sun, clouds, wind speed), and the angle of the Sun preceding and during the survey.
The ElectriSCAN division of Stockton Infrared Thermographic Services uses 4 different types of platforms to accomplish solar farm surveys:
•Elevated Vantage Point
-UAVs (rotor-wing / fixed-wing)
