Question to the mods: is it OK to link a reference website in the answer?

For this, sure, but they are easily found with a quick search.

Who makes a 200 watt 24V panel here in the United States?

I found at least 3 US-based solar panel manufacturers that offer 200 Wp models (under STC).
1. Ameresco 200J (poly), 4200J (mono)
2. Amerisolar AS-5M 185-210W (mono), AS-5M Black (mono),
3. Alps Technology ATI-200 Series (poly)

I know that Global Solar in Tucson makes 200 watt panels, they are thinfilm however, I don't know if that's a dealbreaker.

They will be bankrupt soon.

Not for the first 5 years it isn't .

You can find the list of manufactures who produce 200watt solar panels on enfsolar website. They have list of all solar panels manufacturers. ASW, Atlantis solar, Auxin Solar, ecoSolargy are some the companies among the list.

your panels may have some temperature compensation numbers, or you may be able to surf to the controllers website, and use their on-line array sizer and see what values that gives you

I'd say from late November until early March there are usually some below freezing mornings, like 28F and 30F. We do get arctic freezes sometimes come down and hover sub freezing blue skies for a week or 2. I'm in SW WA.

Not enough irradiance when the sun first hits the panels to cause a problem. How cold does it get where you are? You will probably be ok if your morning temp doesn't drop much below freezing.

Today I was getting 88V from my 2x4 panel arrays. I'm wondering if it can go any higher in winter? If so, I may need to reconfigure as 100V is CC limit.

My guess is that during the Winter just as the sun first hits the panels is when you may see a voltage surge that may push your 100v limit.

There might be ways to mitigate that high input voltage without rewiring the panels but I will let others provide suggestions.

OK, I've had the 2 arrays of 4x100W in series up for about a week now. It has been working fine, and thought I had maxed out the controller (100V limit). Now I'm wondering about three 3x100W arrays. This would lower my 80V to more like 60, and give 16.5A instead of 11. Would the line loss not be worth the extra 100W panel? CC is 25ft away using 8awg cable.

Ya, figured .

Ok, I'll get one. And say, how about keeping the 2 3x100W arrays, and get a 300W panel on third array. My only concern is that 24V is pretty low, as the other arrays together are around 45V. Do they make 48V 300W panels, that'd be too convenient?

No, the voltage on the strings in parallel needs to be kept close. You'd have the equivalent of 108 cells on two existing strings, and only 72 cells on your new string.
