I must say the AIO's do look much neater than normal installs.
I guess they come with heating as a choice?

That should help them in the Winter, I was not 100% they came with heater, but good to hear they should.

How/where did you get that projection because aren't they facing away from the sun in the northern hemisphere?

Thanks for the link.

When I entered ours systems, it estimated June being less than July by 10-15% even though we get less solar in July.
