Infrared thermal imager detects solar panels
As fossil fuel reserves decrease, the prices of coal and natural gas rise to new heights, and many people seek the sun's renewable energy. Installing solar panels on the roof can convert the solar energy into usable electrical energy. In order to obtain maximum returns and high returns for sustainable development, access to high-quality solar energy is the key. The solar panel is the most important part of the solar system. It must generate electricity reliably and continuously, but the solar panel is extremely easy to wear. To ensure reliable operation of solar modules throughout their life cycle, construction professionals around the world use thermal imaging cameras to inspect solar panels installed on roofs or parks.

There are many advantages to using an infrared camera for solar panel evaluation. Abnormalities can be clearly seen on the clear infrared thermal image. During normal operation of solar energy, an infrared camera can be used to scan the installed solar panels. Finally, the thermal imaging camera can scan a large area in a short time. And can detect and repair potential problem areas before actual problems or failures occur. But not every infrared camera is suitable for solar cell inspection, so you need to follow some rules and guidelines to carry out an effective inspection and ensure that the correct conclusion is drawn.

Infrared thermal imaging cameras can also check the procedures of solar panels. In order to obtain sufficient thermal contrast when inspecting solar cells in the area, solar irradiance of 500 W/m2 or higher is required. However, in order to obtain the maximum effect, it is recommended that the solar radiation be 700 W/m2. Solar irradiance describes the instantaneous power incident on the surface in kW/m2. It can be measured with a total radiometer (for overall solar irradiance) or a solar radiometer (for direct solar irradiance). This depends largely on the location and local weather. Lower external temperatures may also increase thermal contrast.
