Solar water heater

There are two types of solar panels or solar cells suitable for domestic use. Flat panel arrays (more than one) are available in different heights and widths:Most are about 1m2

The energy absorbed from the solar panels through a pump, from there passes through a fill and relief valve. The energy then changes forms when it reaches a heat exchanger where it can be stored or used in the form of electricity and space7warer heating.

A configuration of passive thermo siphon is used to connect a number of panels together to maximize solar absorption.

A backup electric and gas water heater is included incase not enough energy has been collected from one of the solar panels: This type of configuration ensures that maximum solar energy is being collected from the rest of the solar panels to offset the defected one:

Evacuated tubes work on the same principle as the flat panel solar cells, but due to their design are far more efficient at collecting solar energy: Evacuated tubes have been around for years and are extensively used in Canada, Germany, China and England:Evacuated tubes use a twin glass tube made of borosilicate glass which makes them extremely durable:

This type of design allows maximum absorption with minimal reflection: The top of the tubes are fused together and all air within the tubes is pumped out at the same time the tubes are exposed to extremely high temperatures: This evacuation of the gasses forms a vacuum, which is an important factor in the performance of the evacuated tubes:

Due to the vacuum process the tubes are extremely efficient at collecting heat from solar energy: A vacuum is excellent at insulation which is why the tubes were designed as such:
The vacuum prevents any heat loss from the tubes due to the highly efficient insulation properties: The inside tube could be as hot as 150C while the outer tube is cold to the touch:

Due to this design evacuated tubes out perform the flat panel models and collect maximum solar energy even in bad weather
