    PowerFilm designed this Soltronix 24W Semi-Flexible Solar Panel specifically for a Thermo King Precedent Trailer Refrigeration Unit. This design includes a unique shape and an integrated fixed power point tracking (FPPT) charge controller.

     

    Compared to other panels on the market, the integrated charge controller delivers more power to the battery and provides for a quicker installation. The custom shape offers access to the radiator cap without having to remove the panel, reducing maintenance costs.

     

    The panel attaches easily to the metal frame of the TRU with four self-tapping screws. Older Thermo King units may need rubber feet as spacers between the panel and metal frame to avoid height obstructions. (Screws and spacers are not included).

    Power Comparison

    30W Thermo King vs 24W PF-TK Replacement IV Curve

    The 30W Thermo King panel, due to cut cells prone to edge defects and a lower quality charge controller, provides 18.4W to the battery (61% efficiency). 

     

    The 24W PF - TK Replacement panel provides 21.1W to the battery (88% efficiency).

  • All connections must be solar positive (red) to battery positive and solar negative (black or blue) to battery negative. Reversing can damage the solar panel. Consult your battery manufacturer if you have questions about the specifications of your battery.
