I live in the Caribbean and am looking to get a solar water heater system. I’m looking into flat panel or evacuated tube system. I got an offer for an evacuated tube system with a stainless steel tank for a descent price. I have a 2 floor concrete house with a flat roof and no trees nearby. i have 2.5 bathrooms. At the moment we are just 2. Given my location, would the evacuated system be better? What should look for?
I got offered this ET system with installation for $1,300 plus tax.
It includes a 120 gallon stainless steel tank.Flat panel systems with a regular 82 gallon tank (non stainless steel) run for the same price.
