The basics: Finishing up house build on little Caribbean island. 2 solar companies, not returning phone calls because busy building/post-Irma rebuilding for the superrich. The house is set up for 2 rooftop systems, both bolted to concrete with perfectly clear aspects. My A/C guy has installed a couple, but I've got to choose a system.

It's really difficult to find any kind of advice about choosing solar HWH systems....I can't even find out whether direct or indirect is best for the Caribbean. We'd also need a sales company or direct manufacturer with good phone support.

ANY guidance, advice, suggestions or links would be very much appreciated.
