I am building an off-grid house in southwest Texas.  The lowest monthly
average temp is 35F and the lowest mean temp is 52F.

What type of commercial solar hot water heating system should I purchase:
flat plate or batch collector?  Any recommendations for a particular product
to use or exclude?

Thanks in advance.

I have a closed loop with 1 4x10 collector which started leaking and was
replaced 2 years ago. I recently replaced the Lockinvar water heater which
was installed in 1992. Not bad considering.  The water heater is electric
backup and 80 gallons. Except for a few month of the year I never run the
backup at all. There are a ton of considerations to be made. How many
people? How much water per person per day?  My  collector is not set at an
optimum angle due to some CC&R restrictions. I believe if I had a family I
would need another collector to the system.  All in all not exactly pain
free, but those long hot showers are rewarding in themselves for me.

Call some contractors and get educated that way. Also will help you
understand what will need to be installed in your area. Low temps in the
30's will require freeze protection. Here in Phoenix it is the same

It will just be my wife and I.  Not sure about water per day because the new
house will be so different from where I live now.  I am guessing 70 gallons
per day.

gallons

With my ex around we had little problems with the 80 gallon that I have.
Winter months the electric back up runs almost daily. I put it on a time
clock now so there it can only run 3 hours a day.  Some times it is a bit
cool but I do not care that much. I turn on the booster on the dish washer
in the winter time as well. Summer time I get and maintain 140-170 F water.
