Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module technology, and more specifically, it relates to a photovoltaic module EL testing device. Background Technology

[0002] Photovoltaic module EL testing equipment can detect internal defects in photovoltaic panels. The luminescent images obtained through EL testing can clearly show the crystal structure inside the photovoltaic panel, and can detect problems such as microcracks, fragments, and black spots.

[0003] Existing portable EL testers typically consist of an EL camera and a tripod. When carrying them, the EL camera and tripod usually need to be separated and stored separately in a case to prevent damage during transport. During testing, the case must be opened, the EL camera and tripod removed separately, and then reassembled. This process is cumbersome and lacks convenience. Therefore, this paper researches and improves upon the existing structure and its shortcomings to provide a photovoltaic module EL testing device with greater practical value. Utility Model Content
