You could but only if you make a rack so they will clear over the vents and skylights. You would not want a panel over the refrigerator vent or cab-over escape hatch. On the roof directly, I think about 300 watts would be the max.

Why do you wamt 500 watts of solar? Usual rule of thumb is 100 watts per battery.

where is this rule written? That's about enough to cover self and parasitic discharge..... useless for a real charge cycle. Some folks actually use their batteries at night.

Not many TC's have 34 feet of roof to put things on . As far as I know all of us use our batteries at night .

1- If you're referring to my roof, I'm not using anywhere near 34' for my panels, but that is not the point and you are confusing things. This isn't the 1st RV I've owned..
2- Where is it written that the "rule of thumb" is 100w per battery? People looking for install help and not knowing better believe this stuff and it is simply inaccurate.

I agree. Every system and need is different and based on usage, but having "too much roof solar" is far better than not having enough. Especially considering how cheap panels are. If panels produce too much it is wasted power. If battery bank doesn't get good charge it is wasted battery life.
