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).

We were contacted by a family in Durbanville to provide them with a quote for:  Retrofit electric geyser to solar.

It helps to timeously empower our client with the correct information:

During the onsite evaluation we noticed that certain standards needed to be implemented and that the geyser was also faulty.  When discussing with the owner, he confirmed that the hot water from their geyser was brown although the water running from the cold tap was clear.  We checked with the geyser supplier, Kwikot, who confirmed that the geyser was still under warrantee.  As standards change over time the galvanized drip tray needed to be replaced by a plastic drip tray and a stopcock needed to be installed.

We provided our client with the abovementioned information and Kwikot therefore came prepared to replace the geyser, install the stopcock & the correct drip tray & outlet.  This was done in a very short timeframe.  Please note that the initial installation was not done by Kwikot or ourselves.  Kwikot did the abovementioned work as part of honouring their geyser warrantee as the supplier.

Our client then accepted our quotation to retrofit their new Kwikot electrical geyser with solar.

Servicing a solar geyser system in Kuils River

Service a solar geyser system…yes or no?

This article is about a *natural flow solar geyser system with a flat panel (as in the picture) which we serviced recently.  The question is to: Service a solar geyser system…yes or no?

*natural flow = thermosiphon (it is where the geyser is located higher than the solar water panel and no pump is required to circulate the water between the geyser and the panel).

After a few years of working hard to harness the sun’s energy to heat your geyser water, various factors may play a role in the continued efficiency of your solar geyser system:

The environment and man may have an impact on the need for a service over time.

  • The sun/birds/squirrels may be working away at the *lagging around the water pipes on the roof;  * lagging is insulation material which limits heat loss.
  • We sometimes find that squirrels and/or rats enter the roof space and damage the Geyserwise controller wires and or lagging within the roof;
  • Dust and other material may collect on the surface of the panel(s) and impact on the absorbtion of the sun’s heat energy;
  • Another factor may be that repairs to the municipal water network may result in debris moving into your solar water panels and impact its efficiency;
  • Just after the installation, the new owners are usually very excited to experment with the different options on the timer and over time they forget and then the settings don’t really suit their needs anymore due to changed circumstances in their household;
  • Maintenance work at the house may result in someone stepping on parts of the solar geyser pipework or other parts and damage occurs;
  • Smaller parts (element, timer, pressure control valve, etc.) may be or become faulty, although we stick to trusted parts from reliable suppliers.

We find that the service requirements differ from area to area due to the weather and environmental differences.  We therefore propose a basic service for our existing clients in order to keep the expenses as low as possible.  If we find that e.g. the lagging need to be replaced, we then first discuss it with the client and get his/her approval to replace it.  The basic service has a fixed cost (if we have to travel quite a distance, we will then discuss additional fuel cost with the client beforehand).

This is a solar geyser system we installed almost 5 years ago.

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.

Solar Juice installs at Eskom Sere Wind Farm

We (Solar Juice) had the privilege to install 2 solar water heating systems on the building at Sere Wind farm, outside Koekenaap (near Vredendal) which is about 350km from Cape Town. (The Sere Wind Farm is Eksom’s first large-scale renewable energy project and this is the first major step in a drive to reduce SA’s heavy reliance on coal to generate electricity). 

This was quite an exciting project to be involved in.  The work safety measures are very strict and well communicated beforehand. It is great to see that the first 7 of the total 46 wind turbines came into action on 10 Oct. 2014. These 7 turbine generators produces close to 16MW power.  This is enough to light up about 30,000 households. An excellent start for this project.

Eskom lowers its carbon footprint with this project:

The 2 Solar Geyser systems will help Eskom by storing the sun’s energy in the geyser water (heat) for utilisation when required.  A 200 liter electrical geyser would have resulted in the burning of at least a 1000kg of coal annually to generate electricity and would have resulted in 4.5 tonnes of harmful CO2 and other gasses to be released into the air every year.  This way, and especially with the wind turbines, Eskom is lowering their carbon footprint in this amazing new project.

Sere Wind farm connects to national grid in South Africa

Posted by: ESI Africa October 17, 2014

The construction of the Sere wind farm reached new heights this week with the energising of the transformers of the first string of seven wind turbine generators, a move that paved the way for Eskom to commence with the final commissioning of these turbines.

“I am sure that the team will continue with the same drive and commitment until all 46 wind turbines are in operation,” said Eskom Chief Executive Officer, Tshediso Matona, chief executive officer of Eskom, South Africa’s utility.

Sere wind farm is Eskom’s first large-scale renewable energy project, and forms part of the utility’s commitment to renewable energy and reducing its carbon footprint.

Eskom’s senior general manager for renewables, Ayanda Nakedi, said: “Last Friday (10th October 2014) we synchronised the first seven wind turbines to the national grid, adding 4.4MW as part of the final testing and commissioning process. The achievement of this milestone is in line with our target date of December 2014 and we remain on track to be in full commercial operation by end March 2015”.

Once completed, the plant will add 100MW to the national grid and contribute to saving nearly 6-million tons of greenhouse gas emissions over the 20 years expected operating life, with average annual energy production of about 298 000MWh, enough to supply about 124 000 standard homes.

“Wind conditions have been favourable, and this past Monday, the Sere wind farm was contributing 15.7MW to the national grid,” said Nakedi

The R2.5-billion wind farm will also help diversify Eskom’s energy mix and contribute to South Africa’s objective of meeting 42% of the country’s power demand with renewable energy sources by 2030.

Matona expressed his appreciation for the work and progress achieved, “My thanks go out to the entire team for enabling us to reach this most significant of milestones. This milestone has been achieved through close co-ordination between various departments in Eskom and our contractors. This is evidence of what we can achieve as an organisation when we work together.”

Describing Sere Wind Farm

Sere Wind Farm is Eskom’s first full scale renewable energy project, situated on the Western Cape Province of South Africa, located north-west of Vredendal, approximately 350 km north of Cape Town. It sits on a 3 700 hectare plot of land in Skaapvlei near the town of Koekenaap Eskom’s Sere Wind Farm will comprise 46 Siemens 2.3-108 wind turbine generators. The project includes construction of a new substation and 44 km of 132 kV distribution line linking the new Skaapvlei substation to the existing Juno substation.
