Why Solar Geysers?

Almost half of the power consumption in the average home is attributed to heating water.

By harnessing the unlimited clean energy of the sun, the GreenAmp Solar Geyser is designed to save more than 30% of your total water heating costs, slashing your household electricity bill dramatically.

What are the benefits of a solar geyser?
  • Environmentally friendly
  • Household electricity cost savings
  • The solar geyser enhances property value
  • Solar geyesers reduce local electricity demand
  • For use as a High Pressure or Low Pressure Unit
  • DIY friendly installation
  • Very, very low maintenance
  • The solar geyser can be used as a pre-heater to existing electrical or gas geysers or the solar geyser can be used as a stand-alone solar geyser

How does solar heating work?

The tank is placed on the roof, facing north on a slant of 20 degrees -30 degrees.  In the case of a flat roof, a stand will have to be installed.

Radiation from the sun heats the surface of the tank, which in turn transfers the heat to the water inside the tank.

The heated water which is now less dense than the cold water automatically moves to the top of the tank by a process known as thermosiphoning. This process continues for most of the day, heating the water in the tank.

When a hot water tap in the home is opened, hot water from the solar geyserr is extracted from the top of the tank.  Simultaneously, cold water is fed into the bottom of the tank to replace the extracted hot water.

Frequently Asked Questions about Solar Geysers

  • How is solar energy “clean”?
    - Energy from the sun is pollutant free with no use of carbon fuels.
  • How would I save costs?
    - By eliminating your water heating costs you can save more than 30% on your overall electricity bill.
  • Is there maintenance on the solar heater?
    - Other than keeping the transparent surface clean, no maintenance is required on the thermosiphon system.
  • Can a solar heater be installed on any roof?
    - Although a pitched roof is ideal, any north facing roof exposed to direct sun will suffice.
  • How hot is the water in the solar heater?
    - GreenAMP solar geysers are designed to heat water in the excess of 60C° in winter and in the excess of 80C° in summer times.
  • Will a hail storm damage the solar heater?
    - GreenAMP solar geysers are hail resistant.
  • What happens when it is cold or overcast?
    - The GreenAMP solar geyser heats water through energy from the sun’s radiation and not from direct sunlight.
  • What if I already have an electrical heater?
    - The GreenAMP solar geysers can be used as a pre-heater to your existing heater, further reducing water heating costs.

Kestrel e150 Wind Turbine

The six blade design is a self-regulating aerodynamic rotor that achieves speed control through blade turbulence, which controls the speed of the rotor with no moving parts and no obtrusive noise. Potential energy harvest is estimated using an average wind speed in order to tailor the most suitable Kestrel wind system to your electrical need.


Kestrel e220 Wind Turbine

The e220 wind turbineis an innovative small wind turbine with an advanced pitch control system that maintains full power in any wind that exceeds the rated wind speed optimising energy harvest capacity. The passive pitch control system and power output at low wind speeds increases the energy harvest on an annualised basis. Water pumping systems with optional water pump controller to reduce utility costs.


Kestrel e300i Wind Turbine

The e300i advanced design moderates noise emissions effectively, making it an inconspicuous power source in all installations and environments. The e300i wind turbine is suitable in all wind classes and has a low start-up torque that requires minimal wind to generate energy. Every feature of the e300i optimises renewable energy generation, increasing energy efficiency and cost saving.


Kestrel e400i Wind Turbine

The three blade design, with a diameter of 4m, moderates noise emissions effectively, making it an unobtrusive and reliable method of renewable energy generation in all installations and environments. By optimising renewable power output and performance, the efficiency of the e400i wind turbine makes it a valuable asset for fulfilling energy requirements.
