Using a Solar Hot Water (SHW) system is the most efficient way to capture the sun’s energy to heat water for use in your home or business. Small 1 or 2 panel systems are ideal for pre heating domestic hot water. Larger systems of 4 panels or more can be used to supplement in-floor heating or for pre heating in commercial or industrial applications.
A SHW system consists of three main parts; panels, storage tank and heat exchanger. There is also a pump, piping and controls. The operation of a SHW is fairly simple. The Photovoltaic (PV) panel supplies power to the control system and pump. When there is sufficient heat in the panels, the circulating pump then pumps a glycol based fluid from the heat exchange unit to the panels to pick up the heat from the sun. The heated fluid is then returned to the heat exchanger. The heat from the fluid is then transferred passively to the storage tank. The storage tank is supplied by cold water from a well or city water. The heat from the heat exchange unit heats the water in the storage tank. The water in the storage tank can get up to 60 C in the summer months and even in winter the temperature can be 40-50 C. The water from the storage tank supplies the hot water tank with pre-heated water, thus less energy is required to make domestic hot water!
