Infrared cameras or Thermal imaging cameras are an essential tool for monitoring photovoltaic systems. They make it possible to monitor the temperature distribution on the modules and detect defects at an early stage before they cause major problems.

Infrared cameras work by measuring the infrared radiation emitted by objects. This radiation is converted into an image that shows the temperature distribution on the object. In photovoltaic systems, infrared cameras can be used to detect hot spots that may indicate defects.

Early detection can prevent major damage, resulting in longer system life and lower maintenance costs. Infrared cameras can be used for both commissioning and regular maintenance of photovoltaic systems.
