Foldable Solar Panels are designed for regular outdoor use, but not for permanent outdoor installations. While a light rain will not damage the panels if they are brought inside and dried before storing, the panels are not weatherproof and should not be deployed in poor conditions. The fabric may discolor and fray with permanent outdoor exposure, and the individual solar modules may be compromised as well.

Always store the Foldable Solar Panel in a cool, dry environment. If the panel is wet, allow it to thoroughly dry before folding and storing it to avoid damage.

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.

A charge controller is not required if the battery capacity is 100x greater (or more) than the panel output. For example, a 100Ah battery would not need a charge controller as long as the panel output is 1A or less. If a charge controller is required, please size it appropriately to the panel output.

Operating Voltage and Current are typical values when tested under load at AM 1.5 lighting conditions. Power performance may vary due to temperature, light spectrum, angle to the sun, and other effects (minimum 95% rated when new).

  1. Unfold the panel 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) (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.

12V Batteries:

  1. Connect panel output to the input of appropriate charge controller, if required (4.5A, 6A, and 10A charge controllers available) (not included) (see Important Notes section for more information).

  2. Connect the desired cable to the output of the charge controller or panel. Use the 15 ft. Extension Cord with O-ring Connectors (RA-11) or 15 ft. Extension Cord with Alligator Clips (RA-8) (not included) when connecting directly to the battery. Use the 12V Male Car Charger Adapter (RA-1) (not included) when connecting through a vehicle’s cigarette lighter or accessory outlet.

  3. If using an RA-8 or RA-11, connect the red connector to the + battery connection and the blue or black connector to the - battery connection. If using the RA-1, plug into your vehicle’s cigarette lighter or accessory outlet. Note: in some vehicles, these outlets are not connected to the battery when the ignition is off, so the solar panel will not charge the battery. Consult your vehicle’s owner’s manual for more information.
