Solar Panels for Solar Water Heater (solar energy 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
