This phenomenon is called the "hot spot effect" of photovoltaic modules. The hot spot effect will reduce the output power of the module to a certain extent. If the heating temperature exceeds a certain limit, it will cause permanent damage such as local burning of photovoltaic modules to form dark spots, melting of solder joints, aging of packaging materials, etc., which is an important factor affecting the output power and service life of photovoltaic modules, and may even cause safety hazards.

[0011] Preferably, a fixing rod is installed on one side of the U-shaped frame, two second sliding grooves are opened in the inner cavity of the U-shaped frame, and four pulleys are installed on the bottom of the shell.

[0012] Compared with the prior art, a hot spot testing device using the above technical solution has the following beneficial effects:
