Solar Thermal Evacuated Tube Collectors
Our Solar Thermal evacuated tubes are ideal for supplying domestic hot water as well as heating swimming pools. Solar tubes ensure a long service life by application of high-quality, corrosion proof materials. Furthermore, the panels guarantee high energy yields with their small collector gross areas.
Due to the circular absorber area, each individual tube always has the optimal adjustment towards the sun, this in turn ensures that both direct and diffuse solar radiation is optimally collected by the circular absorber. In case of a tube breaking it is possible to exchange tubes without emptying the collector unit of the solar fluid. Unused surplus in summer is lower than with a flat-panel collector, whereas the gains in winter are higher.
Useful Design Points
For a solar thermal system to work to its optimum capacity a south facing roof is ideal. However, it is still possible to install a solar water heating system if your home has an east-west orientation by increasing the area of panel installed. One option is to mount one panel on the east orientation to collect heat in the morning, with another panel on the west orientation to collect the heat in the afternoon. It is not advisable to place solar panels on a north-facing roof.
In addition, this roof area cannot be overshaded by nearby buildings, trees or other objects.
The panel should be placed at an angle between 25° to 60°.
The variety of installation methods ensures that almost any type of building can have a solar thermal system installed.
Installation Methods
Our evacuated tubes are suitable for pitch roof and flat roof mounting as well as free standing mounting and facade assembly. The tubes however can not be integrated into a roof; they are always fitted once the roof is completed.
Technical Specification
The Solar evacuated tube consists of 3 main components: evacuated tubes, CPC mirrors and collecting box with heat transfer unit
The evacuated tubes
The evacuated tubes are composed of two glass tubes which in each case are half spherically closed on one side and fused together on the other side. The gab between the tubes is evacuated. In addition, the internal glass tube is provided with on its external surface with a highly selective layer and thus designed as an absorber. It is an aluminum nitrite sputter layer which is characterized by very low emission and very good absorption.
The CPC mirror
In order to increase the efficiency of the evacuated tube, a highly reflective, weather proof CPC mirror (Compound Parabolic Concentrator) is placed behind the evacuated tubes. The special mirror geometry ensures that even at unfavourable irradiation angles direct and diffuse sunlight falls onto the absorber. This substantially improves the energy yield of a solar collector.
Collecting box and heat transfer unit
The insulated collecting and distribution pipes are located inside the collecting box.
In all systems the solar circuit is a closed loop and does not contain the water that you use. Instead the water is pumped around the circuit absorbing heat in the solar panel and transferring it to the water in the hot water cylinder

What is Solar Thermal?
A solar water heating system collects heat from the sun and uses it to help heat your water. It can provide hot water for taps, showers, baths and swimming pools.
Benefits of Solar Thermal Energy
A correctly sized solar thermal system will produce 60-70% of your annual hot water requirements, even on a cloudy day, lowering your usage of oil, gas or electricity and negating the CO2 these fuels create.
1. Suitable for all homes
2. Simple and reliable technology
3. Dramatic reduction in energy costs
for hot water
4. Reduces your dependency on depleting
natural resources
5. Increases the value your property
6. SEI registered product
7. Aesthetically pleasing
8. Your choice of collector ( Integrated in
the roof/roof mounted/ground mounted)
9. Maintenance Free
A CORRECTLY SIZED SOLAR THERMAL SYSTEM WILL PROVIDE 60 – 70 % OF YOUR TOTAL ANNUAL HOT WATER REQUIREMENTS, 100% DURING SUMMER MONTHS.
Our high performance solar panels represent the heart of the solar thermal transfer system; they convert incident sunlight/solar energy into heat. Thanks to their clear, high transparency, low-iron glass, our panels achieve a high degree of heat transmission. The heat is generated through the absorption of the sun's rays by a dark colour coated absorber sheet of the panels. When there is sufficient daylight a pump kicks in and frost protected, non-toxic solar fluid circulates through the system/pipe work. The heat transfer fluid in the piping system absorbs the heat and is pumped to the hot water tank where the heat is transferred to the surrounding water in the tank by a heat exchanger. Your existing method for heating water acts as a backup for when there is insufficient sunlight.

Solar Energy Consumption as Percentage of Total Consumption
Typical example of the contribution by solar to total hot water requirements, this graph is based on a house with 2 solar panels totalling 4.6m2 with a 250 litre tank to serve a family of 4.
Flat Plate Collectors
Our flat plate collectors are know for their efficiency, durability and ease of handling. The laser welded absorber provides high aesthetic result and long life operation. The whole collector is manufactured in absolute industrialized way which ensures the top quality we offer. The collector has been tested in many laboratories around the world and is certified for its efficiency and durability.

Installation Methods
There are several methods of installation available when choosing a CareyGlass Solar system. The variety of installation methods ensures that almost any type of building can have a solar thermal system installed.:
• In roof system (Integrated roof light installation), whereby panels would be mounted once felt and battens are completed, before the roof is slated/tiled, making them more flush with the roof. This system is most commonly used in new builds.
• On roof system (Roof mounted installation). This system is mounted on an existing roof, on both new and existing buildings.
• Facade style system. If there is no roof space available we can mount a system on your wall.
• Canopy style.
• Flat roof system. Panels can also be fitted on a steel frame either in the garden or on a flat roof surface using our A frame
• On an adjacent building, i.e . garage
