    Photovoltaic panel that freezes with excessive heat

    s it normal that a photovoltaic panel does not supply voltage with temperatures of 36/37 degrees C.? It happens to me that this panel in the hottest hours of the day (here in Italy we currently have temperatures of the order of 36 - 37 g. C .) you do not supply voltage and then resume in the hours of less sunshine. Can high temperatures block operation? The only characteristics of the panel I have are those that are attached in the photo.
    Do you have any explanation? When the panel works, it loads normally, delivering up to 5 -5.5 A of current.
    Thank you for any replies

      While power output goes down when panels get hot, you have a bad panel. Return for RMA. Probably interconnect is bad.

          LG 49UJ6500 LCD panel lighter band that goes away
          by howardc64
          49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.

          Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on...

          SAMSUNG UN50TU8000F rebooting, backlight ok. No 12v to panel boards.
          by triplefour
          TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.

          tcon is built into mainboard.
          Only one cable goes to panel boards.
          there is a cable from one panel board to the other that links them.
          cost cutting measure that results in us having harder time to diagnose.
          removing the link to the second panel board allows TV to stay on with stable backlight but no image.
          used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board....

          QN55Q60R Service Menu Panel Help
          by Storyteller12
          I had a the above tv qn55q60r that had a bad panel but everything else good. I had another panel here from un55nu6900 with bad leds and melted diffusers.

          I put the nu6900 panel in and powered it up and it does work but there are lines vertical lines.

          I was trying to change the panel type in the service menu but don’t see my exact panel. Anyway to fix this or someone have similar experience.

          the clear picture is the panel type from the service menus on the nu6900. The other 1 is the panel type that was set for the q60r with the bad panel....

          Missing LCD Panel Voltages VGH, VGL, VCOM (TCL 55P6US Sound & Backlight but NO Picture)
          by maneatingmonkey
          I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.

          There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

          Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages

          The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.
