The Power Film Solar rollable solar panel product specs are here:
http://www.powerfilmsolar.com/products/consumer_ready/rollables/index.htm
The R15-1200 model has a 15v DC output at 1.2 amps. It weighs about 2
lbs, and rolls into a cylinder that is 12 inches long and 5 inches in
diameter. Unrolled, it's about six feet long. Best price I've seen
online is about $300.
If six feet poses a problem,r you could purchase two R15-600 units,
which offer 15v, 0.6 amp output, and daisy-chain them to produce the
same 1.2 amp output. Rolled, the R15-600 is about the same size as
the R15-1200, but weighs only 1 lb. Price is about $200 each, so
there is a substantial savings buying the longer unit.
Power Film Solar offers a range of plugs, cables, chargers and
inverters that work with their solar panels. So you can buy a complete
system to maintain the batteries you need to power your recorder,
mics, computer, and other electric gizmos you take into the field.
All you need now is a reasonably sunny day.
