Thermal imaging, or infrared (IR) thermography, uses an IR camera to visualize temperature differences across a solar panel. Thermal imaging offers a non-destructive, real-time, on-site method.

In the EL imaging system, current is passed through a solar module in a darkened room, and then a cooled Si-CCD camera is used to capture the infrared light emitting from the excited solar module. Crystal silicon area with higher conversion efficiency gives brighter luminescence.

By applying an electrical current to a PV device, EL imaging captures the emitted infrared light using a specialized camera, enabling the identification of defects, cracks, and degradation patterns that are otherwise invisible to the naked eye.

Heat transfer fluids (HTFs) play a crucial role in the efficiency and effectiveness of solar thermal systems. These fluids are used to absorb, transport, and store heat energy from the sun.
