PF Flexible Personal Solar Panel 10 Watt Panels. Take the lightweight, easy-to-pack PF Solar 6 / 12 Solar Panels on your next expedition to the Himalayas or down that nearby trail or dirt road. PF used CIGS, the most efficient thin-film solar technology available, to create ... the Solar. Choose either the Solaris six-watt or 15V panel both of them fold up to the size of a CD wallet and work, even in overcast conditions, to charge your cell phone, digital camera, camcorder, iPod, and other small electronics. A built-in reversing diode prevents the solar panel from discharging your batteries when the sun disappears for the night. PF's Solaris 10-watt panel can even charge your satellite phone or trickle charge your laptop.
