This Solar Panel from Bushnell is a solar-powered accessory that allows you to extend the battery life of select trail cameras in their Trophy Cam line.
Charging the panel fully prior to use is recommended for best results. The internal batteries in the panel are capable of supporting normal camera operation for 2-26 weeks without solar recharge, depending on the camera model and the power demands of the selected mode or application.
If the panel is exposed to full sunlight for 6.0 hours each day, it should be able to provide sufficient power to the camera to allow it to operate indefinitely at a capture rate of 30 images per day, including 15 during daylight and 15 at night.
The panel plugs into the camera's DC input jack via the supplied 6.0' armored connecting cable.
