you wouldnt. in fact why wouldnt you go a 350 watt pannel. what ever you have the room for. just see what the size of the pannel is and then add a inch to each side and get up there and see if it will fit. if it wont then you have to look at a smaller one. if you get a newer larger 24V split cell pannel with a MPPT controler they are more efficient than the older smaller pannels

what I actualy did was make some cutouts from old cardboard of the size I wanted to go with and went up there and moved them around to see what options I had. I went with one 325 watt on my camper and have room for 1 more if I decide to throw another on there.

You answered your own question. (see bold text)

If the 200 watt fits, that's what I'd do.

When I installed solar on my roof back in 2011, I was originally going to do 200 watts. I had it done at a shop. The 150 watt panels made better use of the roof space so I installed two 150s instead.

What's with the little 100 watt and 200 watt panels? Get a 300 - 330 watt panel. Do you have a local electrical supply house? Some of the big name electrical suppliers are carrying solar panels now. Or, seek out a local residential solar installer who may have a pallet or two of panels in his warehouse.

All else being equal...it doesn't matter.

Kits are not usually the best value. Takes a little more effort but buying individual pieces that fit exactly what you need is a better way to go.

Yes I do want to go to, 2 200 watt panels. . That’s 400 total. Only two panels way less roof space taken up than 4 100s. But most companies only offer kits in 100watt panels.

Depends on whether you want to add more later.

I went with a 170 watt panel and a 100 watt panel because they fit where I wanted them. So measure your roof carefully.

For ease in placement?
The two will probably be easier to find good places to put them. Just my guess as I do not have any.:)
