Don't look now, but these is something on our roof

I know this is two posts on the same day, but I got really behind during the end of the semester here in school and I want to make up for lost time. I might even post a third this afternoon.

This is our solar hot water heater panel on the roof. It is going to be connected to a 120 gallon tank, with an electric backup. The solar should be able to heat the water up to 120-130 even in the winter. Since we are in Texas, that does not surprise me all that much, but my concern, being a morning bather, is how will it feel first thing in the morning. The panel is facing mostly south-south-east, so it will not actually catch a lot of the late evening sun. I suspect that in the winter, it will be in the shade by 5:00 in the evening, and 6:00 am is a long time from then. On the other hand, that is why we have electric backup for the system.
