How about some good resources on building solar powered backup systems for QRO and QRP?  Any ideas?

Check Marine supply houses such as West Marine.  Solar power is extensively used in the marine environment, particularly on sailboats.

  All you really need is a Solar panel, charge controller and a battery. A Panel that outputs 1 amp for instance will fully charge say a 7Ah battery in 7 hours of sun. The charge controller maintains the battery, keeping it from overcharging and if the controler has low voltage detection it'll keep the battery from discharging TOO far. The Trace C-12 controller for instance does this. I use a Unisolar US-5 panel (5 watts, .300 amps), a Morningstar Sunsaver 6 controller and a 4 Ah battery. It runs my MFJ 9040 on recieve for quite a while, transmit is a different story. I'll get a large capacity battery and larger output panel soon though. There are LOTS of web sites about solar power, just do a search. Hope this helps. 73 de Tom

I run all my ham gear, packet, HF, VHF, keyer, etc from solar.  I have (4) 64 watt panels and 5 gel cell batteries and a 25 amp charge controller from West Marine.  I think I could get by with one 64 watt 3.5ah panel to do what I need.  I leave packet on 24/7 and operate HF about 2 hours per night.  The charge controller is a must.  It will save your batteries and also keep them conditioned.

It is a great feeling to be operating the radio and the lights go out and you are still on the air...

Currently I use the Nomad 300 from www.solarsense.com to power my Icom 706 for
both emergency usage and field days. It also comes with a 21 watt solar panel.
