Thermal imaging, the technology that is now widely used for a broad variety of preventative maintenance applications is proving ideal for solar panel installers. Tony Hargan of South Survey in Clitheroe sells the FLIR range of thermal imaging cameras and he confirms the falling price of the technology is proving a powerful driver. “Cost is no longer a barrier to installers using this technology. Although the advanced thermal imaging cameras offer more sophisticated functions and the ability to see faults at greater distances, an entry level model can still do the job,” Tony Hargan explains. “Thermal imaging provides a quick, easy and efficient method of pinpointing a problem cell.”
