Reduce your electricity bill with a solar geyser

ESKOM URGES SOUTH AFRICANS TO USE ELECTRICITY SPARINGLY AS COAL CRISIS LOOMS: 17 Sept 2018

JOHANNESBURG – Eskom has called on South Africans to use electricity sparingly as 10 of its power stations are running low on coal.

The utility has confirmed the power stations have less than three weeks of supply left and some even have less than 10 days in their reserves.

Spokesperson Khulu Phasiwe says: “We don’t want to mislead people and create unnecessary panic. At the time, we also don’t want to create a sense of comfort. All we can say is that the risk of load shedding is always there, but we’re managing it.”

Help Eskom and switch your geyser to solar

An electrical geyser can contribute between 40% and 60% towards your monthly electricity bill, depending on your household’s hot water consumption. We at Solar Juice can retrofit your existing electrical geyser with solar and enable you to help lower the pressure on Eskom’s coal crisis.  Many households use only the sun to heat their geyser water from October to March (depending on the weather).

Converting your electrical geyser to solar is definitely contributing towards lowering our country’s carbon footprint one solar geyser at a time and it releases the pressure on the much needed coal resources during this time of crisis.

Solar Juice would love to help you make the best of the sun’s amazing energy.  Our service delivery area: Western Cape (Helderberg, Boland, Cape Town, Overberg, Winelands, Breede Valley, Swartland).

Reduce your electricity bill with a solar geyser

  • Written by  Janine Myburgh, President of the Cape Chamber of Commerce

Predictions: Unaffordable increases in future electricity tariffs

The massive cost overruns on Eskom’s new power stations mean huge and unaffordable increases in future electricity tariffs, says the Cape Chamber of Commerce and Industry.

“We are afraid there is no escape from the consequences of the quadrupling in the cost of the Ingula pump storage scheme and the doubling of the costs of the two coal-fired power stations, Medupi and Kusile,” says Janine Myburgh, President of the Chamber.

“To make matters even worse, the cost estimates do not take into account the huge amounts of interest which Eskom has to pay on loans during the construction period. This includes dollar loans which have to be repaid with weakening rands.”

The original cost estimate for Ingula was R8,9bn but this has now ballooned to R36bn. In April 2007 the cost of Medupi was estimated at R69,1bn but in July this year costs were, according to Eskom, R135bn while the cost of Kusile has increased from R80,6bn to R135bn.

“We learn two things from these figures,” says Myburgh.

“One is that electricity from the Medupi and Kusile will cost well over R1 a unit and that costs will continue to rise each year along with the costs of coal, transport and wages.”

“The second thing we learn is that massive cost overruns are normal for big projects and this will also apply to any nuclear build programme. There are many examples from around the world which confirm this.”

Myburgh says the recent study by the CSIR found that the cheapest “new build” option for additional electricity was a combination of wind, PV solar and gas.

“These three technologies are all ‘quick builds’ and their recent history shows projects are completed on time and on budget and they are not subject to the annual costs increases we see in coal-fired power stations,” says Myburgh.

Eskom had now decided that it did not want to buy any more electricity from independent power producers.

“What this means is that the private sector will increasingly turn to roof-top solar which can already compete with the retail price of electricity. Eskom will lose more customers and as the demand for grid electricity declines the case for nuclear power will fall apart.”

Solar energy vs coal

Solar energy vs coal

Households can lower their electricity consumption:

An electrical geyser contributes between 39% and 50% towards your home’s electrical bill.  This translates to between R390 and R500 per R1000 of your electrical bill.  The biggest saving for South Africa is when we use less electricity during the peak hours (high demand) and we also set the timers to work outside those peak hours.

You contribute towards a healthier South Africa!!

A big THANK YOU to all the households who have switched to solar water heating so far as well as for those in the process of doing so.  To read more about the environmental contribution you make (one installation and 100 installations)….every switch from electricity to solar counts!! Click here

Solar geyser installation Somerset West

A new client contacted us to do a Solar geyser installation in Somerset West. This is in the Rome Glen area for a separate section of their house.  We also *serviced their existing solar geyser system. Our client indicated the exact positions where he wanted the solar panel and geyser to be installed.  He definitely did his homework to get the optimal benefit from the sun.

Installation of a thermosiphon system

We installed this solar geyser system as a thermosiphon system.  A thermosyphon system is when the geyser is installed higher than the solar panel and therefore ensures natural water flow.  (The system doesn’t need a pump to circulate the hot water from the panel to the geyser).  A thermosiphon system requires the lowest maintenance of all the systems – we advise our clients to contact us after 4 to 5 years to service the system.

We definitely cherish the view from this indigenous garden in Rome Glen.

This family has an indigenous garden and all their household’s hot water needs are met by the installation of solar water heaters (geysers).  This combined action ensures low electricity consumption as well as low water consumption (indigenous gardens requires little extra water).  These actions ensures savings on both water and electricity bills.

Solar geyser in Bloubergstrand and kite surfers

Our biggest joy is when a customer, for whom we installed a solar geyser system in the past,
contacts us again to install another.

We did the first solar geyser installation for our client in Onrus about 4 years ago and again in January 2016 at Blouberg Strand.  It shows that it is important to deliver the best service every time.

Our client was very clear about certain specifications:

  1. The solar geyser system must not be visible from any side of the house,
  2. The system must be thermosiphon (it means that the geyser must be located higher than the panels and that the flow between the geyser and the panels must be natural and not require a pump),
  3. It must be a 200 liter system to accommodate their hot water needs.

We discussed the solar geyser installation options with our client and mutually agreed on the following:

The best place for the solar geyser system would be on the roof.  Since it is a flat roof, we fitted brackets for the geyser so that it can be located higher than the panels.  The correct angle towards the sun was decided on for optimum transfer of heat to the water in the solar panels.

With their new home still in the building process it was easy to install the timer in the garage.  We had special access to the roof as provided by the builder.  This means the client get access to system settings and can check what the temperature of the water in the geyser is.  He/she can also adjust the heating and thermostat settings based on their changing needs (summer vs winter and when guests arrives which will increase their hot water needs).

It is standard procedure for us to explain to clients how the timer device works and how to change the settings. We provide the home owner with an easy to read manual (which can also be located on-line if the booklet gets filed in file 13).

Insulation:

All the solar system pipes are well insulated and this geyser is one of the best insulated solar geysers available as well as the solar panels with insulation material at the back.

Support locally produced products solar geysers and panels:

Both the solar geyser and solar panels are produced locally in the Western Cape.  This ensures excellent support from the producers; local job creation, a low (transport) carbon footprint and keep the flow of money within the Western Cape.

…..much to our surprise we saw quite a lot of kite surfers in action. 

We later found out about the South African dream to break the Guinness World record. The previous record was held by Spain where 353 participants participated.  These kite surfers in the picture were preparing for the event on 30th January 2016.  They would be part of the hundreds of local and international kite surfers gathered to complete the 2.7 kilometer stretch from Dolphin Beach to Doodles Beachfront in Blouberg Strand.

It is for a good cause as kite surfers participating in the Virgin Kitesurfing Armada events have previously (before 2016) raised over 3 million for charity.

Kitesurfing is still a new sport in South Africa. The windy beach conditions along the coast have led to a gradual growth of the sport in the region and South Africa is seen as one of the best kitesurfing destinations in the world.

South Africa secured the 2016 Kitesurfing Guinness World record:

The South African attempt was successful in breaking the Guinness World record on 30 January 2016 and secured the number of 415 kite surfers successfully crossing the finish line.

Before this newly built house opens its arms for its proud owners … we went back & check that our installed heat pump works perfectly.

Area: Helderberg/Somerset West.  The installation was done about two weeks ago in upper Bizweni avenue – with a beautiful view of the Gordons Bay mountains and sea.  What a perfect setting!!

Short notes about heat pumps:

A heat pump looks similar to an air conditioner and can be installed either on the ground or with brackets on a wall.

Saving: A Heat Pump offers you a way to use electricity to heat water efficiently. Where an electrical geyser uses three units of electrical energy to produce three units of heat energy, a Heat Pump converts just one unit of electrical energy into three units of heat energy.

We are proud to install this ITS 5.0 kW Super Heat Pump which:

  • Produces 85°C water where other heat pumps produce 65°C water at the same gas pressure
  • Is engineered for comfort and class
  • Delivers maximum hot water

Note:  As you can see the sea in the background….. you can rest assured that this heat pump has been treated with BluGuard high performance coating.  We got only positive feedback about this heat pump over the past few years.  You are most welcome to contact us for more information or a free quote.
