Solene is fully self-automated! Solene knows exactly when to turn on and off daily and collects heat whenever it’s available. When sunlight heats the roof collector, the pump and controller are automatically activated. The pump circulates cold water through the collector, where it is warmed by the sun, and returns the heated water back to the tank. Solene’s backup heating element takes over during periods of prolonged cloudy weather or heightened demand, assuring a seamless supply of household hot water every day of the year.

Understanding Solar Technologies: A Solar Primer --
Most applications for solar in the home or office fall into one of three categories. Because each application has a different need or requirement for the solar energy, the technology is different for each.
Solar Water Heating – Sometimes also called Domestic Hot Water (DHW), collectors designed for solar water heating are made of glass, copper and insulation. They are designed to heat relatively small amounts of water (40 to 80 gallons in a home) quickly, to high temperatures suitable for bathing, laundry and dish-washing. Just as with an electric water heater, most solar water heaters require a circulating motor and a storage tank.
