With Yes Solar your solar geyser will pay for itself!
“Last year I installed those solar panels in my house for the geyser, that energy-efficient kind. Today, I got a call from the contractor who installed it. He complained that the work had been completed a year ago and I still hadn’t paid for them. Hellooo … just because I’m blonde doesn’t mean that I am automatically stupid. So, I told him
Subsidies vir sonkraggeisers droop op!
Die installering van laedruk-sonkraggeisers in die Baai is voorlopig gestaak omdat Eskom se subsidies daarvoor opgedroog het. Die sondraggeisers is n Eskom-projek en word deur hom gefinansier. Sowat 30 586 geisers is al by regeringshuise hier aangebring. George Ferreira, van die maatskappy wat die geisers installeer, het gesê hulle het al 120 000 huishoudings voorsien. Ferreira het op n onlangse komiteevergadering oor infrastruktuur, ingenieurswese en energie gesê die projek is gestaak weens geldnood en hy weet nie wannneer dit hervat sal word nie. Volgens Mnr. Ferreira spaar huiseienaars maandeliks sowat R30 aan krag met laedruk- sonkrag-geisers. Hulle het egter heelwat probleme ondervind tydens die installering. “Talle huiseienaars wat by hul huise laat aanbou het se dakke voldoen nie aan die standaarde nie en ons kon nie installasies doen nie. Ons het ook enkele lekke ondervind omdat vullertenks wat plaaslik vervaardig en SABS-goedgekeur is, foutief was. Ons moes 6000 van die vullertenks vervang. Sommige foutiewe krane is vervang. Van die geysers wat verkeerd geïnstalleer is, het van huiseienaars se dakke afgewaai.” Dié probleme het veroorsaak dat die maatskappy nie soveel wins gemaak het as wat hy aanvanklik bereken het nie.

Load shedding – again?
With winter not in full swung yet South Africa’s electricity shortages are so severe that Eskom is regularly cutting supply to some of its major clients to prevent the entire supply network to collapse. During peak times last month Eskom had to use it’s gas turbines, which should only be used during emergency situations. While Eskom and Ms Dipou Peters, Minister of Energy, maintains that no outages are expected, the market still reacted sharply last week to rumours of South Africa possibly facing a re-occurrence of the load shedding crisis of 2008. Me Hilary Joffe, Eskom’s head of communications, admitted that Eskom’s power reserves was so low the last year that scheduled maintenance work had to be postponed. The current load on the national power network is under severe stress. The situation was exacerbated by the explosion of the Duvha power station at the beginning of the year, resulting in a loss of 600MW in generating capabilities. The 600MW is enough to supply the city of Bloemfontein during peak hours. According to Mr Mike Rossouw, chairman of the Energy Intensive Users Group (EIUG), it happens more regularly that supply to some aluminium smelters and Eskom’s bigger industrial customers has to … Continue reading

Interesting Facts about Electricity
A spark of static electricity can measure up to three thousand (3,000) volts. A bolt of lightning can measure up to three million (3,000,000) volts – and it lasts less than one second! Electricity always tries to find the easiest path to the ground. Electricity can be made from wind, water, the sun and even animal manure. Burning coal is the most common way electricity is made in the United States. The first power plant – owned by Thomas Edison – opened in New York City in 1882. Thomas Edison invented more than 2,000 new products, including almost everything needed for us to use electricity in our homes: switches, fuses, sockets and meters. Benjamin Franklin didn’t discover electricity – but he did prove that lightning is a form of electrical energy. One power plant can produce enough electricity for 180,000 homes. Alternative Energy The bicycle is the most efficient form of transportation known. It uses five times less energy than walking. B.C.’s forest industry obtains 25% of its electricity from biomass — in this case, the waste material from their own industry. A system of distribution and transmission lines brings electricity to southern Manitoba through 70,000 km of lines. That’s … Continue reading

Interesting Facts about Electricity
History The first windmills were developed in Persia in about 600 B.C. About 200 years ago, Alessandro Volta discovered that when two strips of different metals were put in a sulphuric acid solution and connected with a wire, electricity began to flow. Voila! The first electric battery was developed! Think of him the next time you pick up your battery-operated CD player or Game Boy. In 1879, just over 100 years ago, Thomas Edison invented the first light bulb. (Thomas Edison didn’t invent the first light bulb – but he did invent one that stayed lit for more than a few seconds. Think of the incredible changes it has brought to our current world! The first windmill to produce electricity was in Denmark in 1890. In the past, frightened sailors voyaging at night saw ghostly phantoms of bluish light dancing on the masts of ships. Called Saint Elmo’s fire, the light is actually a form of static electricity. In 1986, an accident at Chernobyl, USSR, sent radioactive material into the atmosphere and raised concerns about the production and storage of radioactive waste. What is a kilowatt hour? When we buy petrol, we’re charged per litre. When we buy electricity, we’re … Continue reading

South Africa Solar Challenge
The South African Solar Challenge 2010 is an ambitious, two-week race in solar-powered cars throughout South Africa from the 20th September to the 2nd October. Teams are to build their own cars, design their own engineering systems and race those same machines through the most demanding terrain that solar cars have ever seen. The South Africa Solar Challenge promotes renewable energy technologies (specifically photo voltaic or “solar cells”), educational excellence in science, engineering and mathematics and creative integration of technical and scientific expertise across a wide-range of disciplines. The challenge is also a hands-on experience for students and engineers to develop and demonstrate their technical and creative abilities. Yes Solar were lucky to catch up with the Japanese team in Jeffrey’s Bay on the 29th of September. We were astonished by the speed of this little car and were told that it reached a top speed of 171km/h at one stage during the challenge. They however stay within the speed limit as this is one of the rules of the race. The race end in Pretoria at the Innovation HUB (Arriving from 10am to 5pm)

Ways to reduce your electricity bill Step three:
Get a geyser blanket The exact savings are hard to predict, but fitting a geyser blanket around your geyser and insulating your hot water pipes is recommended, says Palmer, as these prevent heat loss when the geyser is switched off. Geyser blankets range in price from R90 to R400 – only buy those that are SABS-approved, Eskom-endorsed and flameproof. DIY kits are available but it’s easiest to ask a plumber to install the blanket, at a cost of roughly R250–R450 per hour (it shouldn’t take longer than an hour).

Ways to reduce your electricity bill – Step One:
Opting off the grid To live off the electricity grid, says Duncan Palmer from the Centre for Renewable and Sustainable Energy Studies, you need a number of solar panels, a wind turbine (depending on where you live), an inverter and some batteries. ‘Solar energy from the sun is harvested with photovoltaic (PV) panels, which convert the solar energy directly into electrical energy. An electrician wires the inverter into your existing electrical reticulation circuit.’ ‘To sustain normal electricity habits and supply a regular house, you will need about 6kW of PV panels, which will cost around R210 000,’ says Riaan Meyer, from the Centre for Renewable and Sustainable Energy Studies at the University of Stellenbosch.‘Adding the inverter, batteries and other components will up it to R500 000 – pricey, but you’re investing in 20 years’ worth of electricity.’ But while an entire solar power system may be out of reach of most people’s budgets, there are some simple steps you can take to lighten the load. According to Eskom, a household’s largest electricity expense is water heating, which typically accounts for 40–50% of the monthly bill. Installing a solar geyser system to cater for the needs of a family of four … Continue reading
Benefit from SWH Rebates while you can
Eskom generates about 95 percent of the electricity used in South Africa. The company has been battling with electricity shortage since January 2008, but its problems date a decade earlier and are due to lack of investment in new capacities and in updating the existing power stations. Last year, Eskom increased its tariffs by 31 percent and asked for 35 to 45 percent annual increases for three years in order to scrape together about R400 billion needed to build new power plants. However, in February 2010 the National Energy Regulator of South Africa (Nersa) approved lower increases: 24.8 percent for 2010/11 financial year, which will bring the average Eskom electricity price to 41.31c per kWh; 25.8 percent for 2011/12, bringing the average Eskom electricity price 51.68 c per kWh; and 25.9 percent in 2012/13, making the average Eskom electricity price 65.06c per kWh. Eskom will use part of the money it gets from the higher rates towards increasing its solar water geyser subsidies, from about R2,500 to about R7,000. The cost of subsidizing solar geysers is lower than the cost of building a new power station. With the new subsidy in place, almost half of the cost of a solar … Continue reading

50% Renewable energy by 2030 for South Africa – WWF
One-half of South Africa’s electricity generation could come from renewable energy sources by 2030, the World Wide Fund for Nature (WWF) said in a new report on Tuesday, 10 August 2010. “Renewable energy is not just an environmental issue anymore. It is about assessing the health of our economy going forward,” said WWF climate change programme manager Richard Worthington. He said that reaching the 50% renewable energy target by 2030 was distinctly feasible, despite the country’s heavy reliance on coal to produce electricity, and added that it was necessary to ensure low-carbon re-industrialization, which would be required under emission reduction commitments in the climate change arena. The report, entitled ‘Renewable energy in a just transition to sustainable electricity supply’, argued that South Africa had the potential to rapidly upscale its use of renewable energy, and with a combination of energy-efficiency measures, this would result in cheaper electricity over the medium term. The report also introduced the sustainable national accessible power planning (Snapp) tool, which was commissioned by the WWF, and was freely available on the Internet. The Snapp tool allowed for interrogation of government’s proposed energy plan, and allowed for the modeling of different energy scenarios, depending on the different inputs made. … Continue reading
