From OS, Japan, comes a portable solar panel (GSR110B) using Fugi Electric Systems' flexible thin film solar technology. The system weighs approximately 3kg and is capable of generating 40W at 12V. Lithium-ion batteries store energy not being used, or to be charged before deploying. The most interesting feature is the ability to pair two together to produce 80W collectively. Although this is the cap, I ask why not combine more together for even higher wattage? OS's target for The GRS110B was be deployed as emergency power for communication equipment. Of course, it can be used for anything else. These have been selling since January 2011 for 60,000 yen, or approximately $700 USD. A bit high, but can you put a price on 40W in a disaster?
