Once again - I truly appreciate all the comments. For me - portable is mandatory - I'm not parking in the sun! I'm thinking 50 to 60 watt panels - 2 to start - would be perfect; I can always add more if needed.
See, my CO detector is battery operated. With nothing 'on' except the battery monitor, I'm pulling .25 watts - with the monitor - so my propane detector ain't pullin' any power either! My fridge runs on propane, and while I do have a mobile freezer (for dog food mainly) - it pulls 3 amps for a few minutes when it turns on. Lights - 1 only at night - pulls 1 amp. My computer I run off battery and recharge - with multiple back-up batteries. See . . I don't pull much power! And if I run the gen 1 hour a day to boost some power - I"m ok with that!
Now - where to find small panels that are not a "kit"????
