You won't find a USB to female cig because it's going from 5v (USB) to 12v (Cig) and that can't be done without wasting a boatload of power and producing a lot of heat. Male cig to USB can be easily found because they're going downhill--12v from the car to 5v for the USB.

12v solar panels directly produce 12 - 17 volts output. These guys who sell solar charge stations with 5v USB only are making a marketing decision and converting the 12v from the panel to 5v USB.

You can hook a 12v female directly to the output of a solar panel if whatever you plug into the cig can handle 12-17 volts DC. What are you trying to power?
