The 24 Watt Solar Panel with Integrated Charge Controller brings together PowerFilm’s 30 years in the solar industry with custom solutions using high-efficiency SunPower monocrystalline (c-Si) solar cells.   


The PowerBoost series of charge controllers utilize high-efficiency DC-DC converters and a proprietary power point tracking system to optimize the power collected from the solar panel and efficiently charge a battery.  


The PowerBoost will provide the most power into a battery and extend the battery’s lifetime. This charge controller is designed specifically for use with solar and will not overcharge a battery like with 3 stage chargers connected to solar modules.


Leveraging our deep expertise in custom encapsulations, varied substrates, and total electronics, the Soltronix 24 Watt Solar Panel provides unsurpassed efficiency delivering more power to your system.

What's included:

How To Charge
  1. Set the panel on the ground (or other surface) with the solar side facing up and pointed towards the sun.

  2. Use the grommets on each of the corners and a tie cord to hold the panel in place and reduce loss or damage from high winds.

  3. Connect the appropriate accessory and cable for the type of device you will be charging.


  1. Connect the 12V Female Car Charger Adapter (RA-2) (not included) to the panel.

  2. Use your own USB car charger adapter to connect your device to the RA-2 or use a 2.4A Dual USB 12V Adapter (RA-14B) (not included) to charge USB electronics.

Selecting a battery:

  • Soltronix Solar Panels are compatible with all 12V flooded lead-acid and AGM batteries (10Ah or larger are recommended) and many LiFePO and Li-ion batteries (consult battery manufacturer to confirm solar compatibility).
