For people who need warm water, you can check out this new simple to install solar water system from FAFCO, Inc. It thrives on sunlight for power and can be installed inside a day. It comes equipped with a solar system in a box and can even function with your existing home heaters.
A switch senses when the roof temperature exceeds the tank temperature, turning the collector on. It channels water through the unglazed panels, absorbing the sun’s heat. Heated water is then transferred to the hot water tank for storage until needed.
When not in use, water in the solar collectors is stored in the drainback tank, preventing the water from freezing.
The price for getting one plays somewhere between $2,200 to $5,000, a lot cheaper than the usual standard home solar electric system’s price of up to $50,000.
