Solar radiation is radiant energy emitted by the sun, consisting greatly of electromagnetic energy.

Yes.Silver Solutions  high efficiency solar collectors can absorbs 93% of  the sun energy.  On sunny days the water can be brought to boiling point . The average required temperature in a home is 65°  however,we can calculate the amount of  radiation  you need for the tank to avoide boiling water.            

A heat pump Geyser collects "free energy" just like a solar water heater.

OPERATION
A heat pump Geyser works by transferring heat – not by converting electrical energy in to heat. It removes the energy from the warm air in the environment. This energy is converted and used to super heat your water which is then stored in the insulated storage vessel.

A small amount of electricity is required to operate the compressor.

The quantity of heat delivered to the geyser is 4 times the quantity of electricity used.

Yes.System performs very well even in overcast and low temperature conditions.                                          

Glass evacuated tubes are the key component of the Evacuated Tube Heat Pipe (ETHP) solar collectors. Each evacuated tube consists of two glass tubes. The outer tube is made of extremely strong transparent borosilicate glass that is able to resist impact from hail up to 38 mm in diameter. The inner tube is also made of borosilicate glass, but coated with a special selective coating (ALN/AIN-SS/CU) which features excellent solar heat absorption and minimal heat reflection properties. The air is withdrawn (evacuated) from the space between the two glass tubes to form a vacuum, which eliminatesconductive and convective heat loss.

In order to maintain the vacuum between the two glass layers, a barium getter is used (the same as in television tubes). During manufacture this getter is exposed to high temperatures which cause the bottom of the evacuated tube to be coated with a pure layer of barium. This barium layer actively absorbs any CO, CO2, N2, O2, H2O and H2 outgases from the tube during storage and operation, thus helping to maintaining the vacuum. The barium layer also provides a clear visual indicator of the vacuum status. The silver colored barium layer will turn white if ever the vacuum is lost. This makes it easy to determine whether or not a tube is operating correctly.

All products endorsed by Silver Solutions are SABS tested and meet the required standards   are ISO 9001/2000 compliant. the heat pump water heater unit have an  IEC tets compliance.

 Silver Solutions Plumbers a  IOPSA approved they will fit your system according to your needs and preferences.

Under normal circumstances no maintenance of the system is required. Broken tubes can be replaced yourself, no special skills are required.

For the average family at the rates electricity increases were approved in South Africa most systems pay for themselves in two years.

Contact Silver Solutions through our email address or telephone numbers. Our installer will visit your home to assess your needs and preferences and provide you with a quotation

After an assessment of your home, the installation can be done in a few hours.

Solar Geysers are commonly used throughout Europe where in temperatures as low as -10° C. Performance is reduced in extreme conditions but Highveld winters offer extremely strong radiation which provides good heat output.

Yes.System performs very well even in overcast and low temperature conditions.                                           

Solar thermal includes solar water heating, space heating, cooling and refrigeration , desalination  process heat and agricultural crop drying

Evacuated glass tube collectors have the following advantages:

1. Due to their cylindrical shape, the solar tubes are able to passively track the sun throughout the day. (A flat plate collector only provides peak energy output at midday when the sun is perpendicular to the collector's surface.)
2.  Air is evacuated from the solar evacuated glass tubes to form a vacuum. This greatly reduces conductive and convective heat loss from the interior of the tube. As a result wind and cold temperatures have less effect on the efficiency of the evacuated tube collector.
3. Evacuated tubes can often be used in subzer temperatures without the system sustaining damage. Flat plate systems often require expensive and complicated antifreeze systems to be installed.
4.  Evacuated tubes are strong, long lasting, and should one be broken, inexpensive and easy to replace. If a flat plate collector panel is damaged the whole panel must be replaced.
5. Due to the high efficiency absorption of solar radiation even during overcast conditions, combined with excellent insulative properties of the solar tube, solar tube collectors can heat water all year round.
6. Due to the various advantages of evacuated tube collector over flat plate collectors, a smaller collector can be used to provide the same heating performance. For example, a standard household of 4-5 people would usually require a 100L-150-200L water storage tank. Depending on your location, only 30 evacuated tubes would be required to provide all summer hot water needs and a large percentage in other seasons.
7. When averaged over an entire year, evacuated tube collector heat output per net m2 of absorber area, is between 25% to 50% greater that a flat plate collector.
