Evacuated Tubes are more productive than flat plates (about 20%). It also requires less maintenance. Evacuated tube systems also outperform the flat plate systems on any roof (even if it is not north facing). However, a flat plat’s performance will be perfect on a north-facing roof and it is visually more attractive. On the other hand, it requires yearly maintenance.
We propose to use evacuate tubes when the elevation of your roof is 45 degrees Celsius or more off-north to the west or the east.

If you do not have a north facing roof, we propose to install the evacuated tube system on your roof (west or east). We assess the roof and roof space when doing the site visit and would propose a bigger size collector. For instance: normally you would need a 20 tube system with a 200L solar water geyser. If your roof faces west or east, and depending on the exact direction, we shall propose a 24 tube system to increase productivity and performance on your system.

If you have an existing electric geyser in a perfect working condition and you want to keep it, we convert your existing geyser to a solar water geyser. We call it a retrofit system. You will not lose your guarantee on your existing geyser.

The water in your solar geyser would be heated to boiling point.  However, all geysers are supplied with a safety valve which opens as soon as your geyser is heated to 80 degrees Celsius to allow pressure to release.

An average household experiences full recovery of their solar energy investment within a period of 20 – 30 months (depending on your electricity consumption).  You would enjoy considerable savings in electricity costs over the lifetime of your solar energy investment. The savings will blow your mind. You will also be a contributor to a greener and sustainable future.

Eskom offered rebates for systems installed until the end of January 2015.  Subsequently, the Department of Energy/Eskom extended the offer until the end of April 2015.  The whole industry awaits further communication. Since the programme’s termination at the end of April 2015, nothing was introduced as yet. We shall keep you informed and post it on our website as soon as it is introduced. At this stage, it is not likely.

Yes, absolutely.  When the solar energy requirement to heat your water is not met due to lack of solar energy, seasonal change or any other reason, your solar geyser would automatically shift to electrical heating and your hot water would continue seamlessly. We set your timer to check your water temperature. The electrical element will be your back-up.

Make sure the company you use is a reliable, registered company. The solar industry has a lot of “bakkie installers” who will not necessarily be in the industry in a few months time.
  • Company must be a member of SESSA
  • Look at the guarantees
  • Make sure the product has the SABS mark
  • Make sure the installation will be done according to SANS regulations.
  • Make sure you get a COC on your electrical installation
  • Do not compromise on quality – it is an investment! You are not going to look for a “cheap” vehicle or house. The same with your renewable energy.

Not at all.  Our solar geyser components are correctly temperature rated and non-flammable even in extreme heat.  The majority of our geyser components are manufactured from stainless steel, aluminium and glass.

This varies according to the logistics of each site, generally 6-8 hours.

This depends on the type and capacity of the geyser.  The appropriate geyser for your requirements is a function of the number of bathrooms and persons residing in the home.  We would advise you on the most appropriate size solar geyser for your specific requirements and needs. Normally a 150L geyser would be sufficient for 2 – 3 people. In case of more than 4 regular residents, we recommend that you upgrade to a 200L or 2 x 150L geysers (especially if some of the people are not regular residents). Please speak to one of our consultants to find out what would suit you best.
Normally the calculation is 50L per person residing in the home.

If it is a Geyserwise Max, it is compatible. However, a normal Geyserwise controller is unfortunately not compatible. We shall include a Geyserwise Max in our Solar Geyser installation.

These control devices assist the homeowner in proactively managing the operational times of their geyser. You could, for example, program the on and off times of the electricity of your geyser.  In addition, these devices also clearly indicate the temperature of the water in your geyser and the panel at any time, which is very useful.

Solar Water Heater Accreditation and Marketing Programme: City of Cape Town states:

High pressure solar water heaters (ie. with a pressurised tank), whether they are flat-plate collectors or evacuated tubes are not at risk of damage from low water pressure or short periods of no pressure (water outages). In cases of low water pressure from the municipal supply, the geyser or storage tank will be refilled at a slower rate and the solar water heater will not be adversely affected. Even in cases of water outages or zero water pressure, high pressure solar water heaters that are installed correctly, can withstand short periods (a few days at a time) without water with no adverse effect on the panel, geyser or pump.

If water outages are expected to last longer than a week, the City advises customers to cover the solar collector panel with reflective sheeting (eg. sisalation) or a dark tarpaulin or blanket. Nevertheless, it is expected that water outages will last a number of hours not a number of days or weeks. Once water is reconnected, the user may experience cold water for a short time.
