Harnessing energy from the sun is a great way to save energy and reduce the environmental pollution and the greenhouse impact on the earth. Solar energy can meet part or all of a home's hot water needs. Solar water heaters are widely used for domestic hot water, pool heating and space heating needs. Geographic location, system design, solar collector orientation, and collector size will determine how much energy can be provided for water heating. Solar water heaters come in different design and performance.  Some systems have back-up water heating such as electricity or gas. A solar water heating system usually consists of a hot water storage tank, a solar collector that absorbs solar energy, a back-up energy source, and a pump for forced circulation systems.

There are two main types of systems: passive and forced circulation. A passive water heater consists of a water tank integrated into or located above a solar collector. In an integrated collector storage system(ICSS), the water is heated and stored inside the collector. These systems are suitable only for warm climates where there is no risk of freezing. In a passive system where the storage is separate from the collector, as water in the collector warms, it flows by natural convection through the collector to the storage tank. A forced circulation system requires a pump to move water from the storage tank to the collector. There are several types of solar collectors. Most consist of a flat black-coated copper plate, with water tubes attached to the absorber plate. As solar energy falls on the copper plate and is absorbed, the energy is transferred to water flowing in the tubes. The absorber plate is mounted in a casing that has a clear covering and insulation to protect the absorber plate from heat loss. Other collectors include an ICSS and the evacuated tube collector. ICSS combines the function of hot water storage and solar energy collection into one unit. Evacuated tube collectors produce higher temperature water and are more complex than flat plate collectors. Evacuated tube collectors consist of a series of tubes that contain a heat pipe to absorb solar energy and transfer it to a liquid medium. The tubes are evacuated in vacuum so that there is almost no heat loss from the tube.

Most solar collectors are roof-mounted, while ours integrates the collector and the water tank into one compact unit and makes it movable with the wheel base(optional). This unit(shown top left) is ideal for consumer that has no access to or simply dislikes the roof mounting installation. As shown above, this  innovative design makes the unit a convenient fit for the balcony and patio requiring only the easy hookup to the water pipe. We also invented the tilt-wall-mounting unit( shown top right) which blends the slim-thin collector plate into the building wall for the best appearance.
