The use of thermography in photovoltaic systems offers numerous advantages, primarily related to preventive maintenance and increased system efficiency. It enables the identification of hot spots and thermal anomalies in modules and connections that may not be visible to the naked eye. By detecting defective cells, loose connections, or overheating inverters, system efficiency can be maintained at optimal levels, preventing energy generation losses. This guide lists companies that provide thermography services to third parties, along with the regions in which the companies operate and the additional services they offer.
