  1. My Lord! Will it come to that?!

  2. Most of the so-called rollup/flexible “12V” solar panels actually put out an industry standard voltage of about 18V in full sun. All panels are supposed to be hooked to a charge controller and battery (that’s basically the commercial setup discussed). You can make a very simple solar battery controller with a LM317 that will do any battery pack type by making it adjustable–set it at the float voltage and let it go. You can then take the “buffer” battery system with you, such as a RC/modelers LiPO or NiMH bank of about 5000-7500mAh (think stuff for quads), hook it to up a DC/DC Buck UP/DOWN adjustable regulator with LED read out, and get any voltage you want–just carry the coaxial DC male plugs that you need. Those Bucks nominally pound out up to 100W. The 5000mAh NiCd pack I’m looking at here weights in at 1 lb 3 oz. The circuitry is a few ounces. The biggest pain in the ass in terms of size-wise packing is the roll up panel.

  3. This is something that now gets heavy play in the V2.0 Workshop. My observations over the past year and a half teaching show this to be an area that needs improvidence among the beginning commo types.

    Also to keep in mind is how much juice your field electronics require.
