Awesome thread!! Thanks so much, Bruce, for the super-helpful breakdown, and to everyone else for the additional tips.
To summarize, if I want a solar system, a recommended, solidly functioning system would include (prices are rough estimates based on amazon):
A minimum 65w solar panel--preferably over 100w, since prices have come down since 2006 ~ $150Am I missing anything?
A PMW control panel for managing inflow/outflow for battery/panel/charger ~ $70
A charger/maintainer ~ $86
A deep cycle battery, preferably AGM, assuming I can find AGM-compatible components at a price I like ~ $240 (zoiks!)
We generally camp for less than 1 week, so I'm assuming 1 battery will suffice--we don't need 2?
If I want to trim some dough off of this total, I'm guessing the best item to target is the battery? Opt for a regular marine battery instead of a deep cycle?
