We took a trip this weekend and found we used around 35 amps a day--we're doing better now that we have the LEDs. No big problem since we had a generator with us but we hate the noise. Brings back memories of hurricane Sandy.
I found a 6 volt side by side battery box from Century Plastics that will fit my trailer bracket so right now I'm leaning toward spending the money and buying two 6 volt batteries.
As far as solar panels go, I agree at least 200 watt would be ideal for our needs but as I said, I am cheap and want to do this a bit at a time. Whatever we end up doing we want to make sure we have the ability to expand to 200 even maybe 300 watts. If I understand this correctly the controller has to be at least a 30 amp controller or do I have this all wrong.
Has anyone had any experience with these sort of flexible monocrystaline panels? They're more expensive than the standard panels of course but I love the weight of these and the fact that they can be installed by adhesive or even (I'm not sure if I'd trust this) Velcro.
