If you have one, are you really saving money after taking into consideration the installation costs?
Where does one find what models are available and installers who are familiar with them?

I have 2 solar collectors, consisting of glass-enclosed arrays of copper tubing, on the roof with a total area of 50 square feet. The collectors face south and at a 35-degree angle to the horizontal (which is the latitude where I live). Water is circulated between an 83-gallon storage tank and the collectors by a pump whenever the temperature in the collectors exceed the temperature in the storage tank. The outlet of the storage tank is connected to the inlet of a gas water heater, and the inlet to the storage tank is connected to the cold water supply. Whenever hot water is used in the house, it flows from the gas water heater. Preheated water flows from the storage tank and that water is replenished from the cold water supply. During sunny weather, hot water is supplied at essentially no cost. The system was installed by a professional company during the 1970's at a time when the state offered a generous tax incentive.

I don't know about all that but i took 3 old black plastic gas tanks that came off junk cars and mounted them on my roof run my water lines to them by the way i have a flat roof anyway that's all i shower with in the summer time i get plenty of hot water for free and the system was free not to mention the recycling of parts . All in all you do save with any solar hot water system that you chose to use
