POWEROPTIMAL, a frontrunner in innovative sustainable energy and demand management solutions, has partnered with the South African subsidiary of Swedish global appliance giant Electrolux, to bring cost-effective, sustainable solar photovoltaic (PV) water heating solutions to the South African market.

This exclusive partnership will see the PowerOptimal’s Elon solar PV water heating technology sold alongside Electrolux’s well established Kwikot Superline electric water heaters (geysers). With deployment of the PowerOptimal Elon range, a customer can add solar capability to most standard electric geysers, without the need for an inverter or battery. It is the most straightforward and most convenient means to take advantage of solar and traditional power in an existing solution.

“We are very pleased to announce our partnership with PowerOptimal. The company’s sustainable energy solutions align perfectly with our global commitment to sustainability, which is to shape living for the better”, states Mark Moyce, National Sales & Marketing Director at Electrolux South Africa. “By including the Elon into our range of water heating solutions, we are offering developers, builders and all users of geysers a means to take advantage of the abundant solar resource we have in this country at a fraction of the cost.”

According to both parties the partnership makes perfect sense, as the organisations are an excellent cultural fit, the technologies integrate seamlessly, and the technical excellence from both are providing a superior technology solution designed to support and grow mass adoption of sustainable energy.

The innovative PowerOptimal Elon range enables direct connection of solar PV panels to standard electric geysers. It requires no inverter and no batteries, is cost-effective, offers a long lifespan and requires almost no maintenance, making it one of the lowest cost per unit of energy (kWh) solutions for water heating available on the market today.

“We are honoured to partner with Electrolux. The company’s market coverage, quality standards, and market-leading customer service make them the perfect partner for our Elon solution,” states Richard Fearon, CEO at PowerOptimal. “Through this exclusive partnership, all PowerOptimal water heating solutions will be recommended and exclusively sold by Electrolux in South Africa. Together we are looking forward to leveraging the technical capabilities of both companies to bring sustainable energy to a larger market of people, previously inhibited by the sheer cost of solar PV technology.”

PowerOptimal’s Elon range solution can run entirely off the grid, or with grid AC power as backup. In addition, it can be used by property developers for conformance to SANS 10400-XA’s Regulation XA2, which requires that at least 50% of the annual water heating requirement for all new buildings shall be from a source other than grid electricity.

The Department of Mineral Resources and Energy (DMRE) is finalising an internal audit on a bidding process to enable the finalisation of contractual arrangements with appointed service providers for the department’s National Solar Water Heater Programme.

Following the conclusion of the audit, the installation of solar water heaters (SWH) is set to resume.

The DMRE has not installed any SWHs in the 2019/20 financial year.

In a response to a Parliamentary question by the Democratic Alliance’s (DA’s) Kevin Mileham, who is the Shadow Minister of Mineral Resources and Energy, the DMRE confirmed that installation companies had been appointed in December 2019.

When asked about the number of units still in storage, the department said it had procured 87 206 SWH baseline systems from bid number DOE 008/2015/16, from which 150 systems were installed in the Sol Plaatjie municipality on a repair and replace programme during the 2018/19 financial year.

Another 200 systems were installed during the same period at a pilot project in Nelson Mandela Bay municipality, with the remaining systems in storage – some at State-owned entities, municipalities and suppliers/manufacturers’ storage facilities.

The monthly storage fees, however, vary depending on the number of days in a month, the DMRE indicated. As an example, for a 30-day month, the storage costs amount to just over R7.9-million, while in a 31-day month, storage costs are just under R8.2-million.

In terms of the supply agreement for the supply of the SWHs, the department said it had “both financial and contractual obligations” to settle additional storage costs in line with the extension of time on taking delivery of the manufactured goods.

However, the DMRE noted that a delay was experienced owing to participating municipalities’ delay in concluding framework agreements in accordance with the Intergovernmental Framework Act owing to the project being implemented across the different spheres of government and the need to clearly outline roles, responsibilities and obligations of each of these spheres during the programme’s implementation.

Following the delay, the DMRE partnered with the Department of Labour and Employment (DoL) and the Central Energy Fund to facilitate the training of installer assistants.

South African startup company Plentify has won the South African edition of the EDF Pulse Africa innovation competition.
The competition is aimed at supporting African innovators committed to the continent’s energy development.

Plentify turns water heaters into grid-connected thermal batteries, which intelligently “recharge” when electricity is abundant on the grid, thereby improving reliability, decreasing reliance on expensive generation and saving water heating costs.

The company achieves this using an easy-to-install Internet of Things controller, a mobile application and a cloud-based artificial intelligence engine, which turns each water heater on or off, based on the needs of the user and the grid.

As winner, Plentify will participate in the grand finale of EDF Pulse Africa, which will be held in Paris, France, in November.

EDF Pulse Africa was created in 2017 by integrated electricity company EDF to discover the African continent’s technological gems and support innovation by involving local entrepreneurs in the development of innovative offers.

The EDF Pulse Africa tour spanned seven countries on the continent, discovering candidates that were plugged into their local economies.

The winner of each national edition is awarded a place in the finale.

Seven startups were selected to compete in the South African final, presenting energy solutions in off-grid power generation, electrical power applications and services, and access to water through the use of electricity.

The competition was open to startups and small and medium-sized enterprises with fewer than 50 employees in the 54 African countries.

When Pracash Arendse got a job at the Isolar factory in Atlantis he was excited that he would be able to provide for his family. Jobs are hard to get in this suburb north of Cape Town, and many households live in poverty.
Arendse, who lives in Atlantis’s Protea Park, is now facing a daunting task of providing for his wife and three children because he and his fellow employees last received wages in February.

Isolar manufactures solar geysers. Because of a lack of orders from the Department of Energy, the company has been on the verge of closure with 85 jobs at risk. GroundUp has reported how the company has been let down by government. The company started in the first place because of a government subsidised programme to buy solar geysers. But the programme has crashed due to a budget cut from R384 million to R0.

With no funds in sight to pay its employees, the company advised its 85 employees to claim benefits from the Unemployment Insurance Fund (UIF).

But the employees have not been through a retrenchment process, and according to labour lawyer Michael Bagraim this is illegal. “They haven’t been dismissed yet. They should have been retrenched first to get UIF and severance payment,” said Bagraim.

He advised the factory’s employees to go to the Department of Labour to lodge a complaint about non-payment of wages and thereafter to go to the Commission for Conciliation‚ Mediation and Arbitration (CCMA) to launch an application for unfair labour practices.

The SA Bureau of Standards (SABS) has been strongly criticised by business, which says the entity is losing the country at least R4 billion a year in exports in the manufacturing and engineering sectors alone.

This comes after years of businesses complaining about a lack of testing by the SABS, resulting in manufacturers losing contracts because they are unable to obtain the SABS mark timeously, or they have been unable to renew 2 600 permits to use the mark.

Trade and Industry Minister Rob Davies is assessing representations from the SABS board on why he should not go ahead with his intention to put the entity under administration for not performing to its mandate. The SABS falls under Davies’ department.

Steel and Engineering Industries Federation of Southern Africa economist Marique Kruger said the lack of testing and certification by the SABS within the required time frames was a concern, as certification was often needed for products to be sold locally and internationally.

Kruger said trade deals being delayed or cancelled due to a lack of testing hit smaller businesses the hardest and caused a loss of billions in exports a year in the manufacturing and engineering sectors.

“The impact on the domestic production value chain is also huge,” she said.

Director at GAP Holdings, Theuns van Aardt, said manufacturers in the solar water heating industry were “tearing their hair out” because they “cannot get a system approved by the SABS”.

He said the piping, pump and valve industries were similarly affected, and were “being put at massive risk”.

Business development manager Carolien van der Horst of the SA Capital Equipment Export Council said the SABS was also failing to audit the local content of products supplied in government contracts as stipulated in government’s Industrial Policy Action Plan.

Van der Horst said this resulted in companies possibly supplying imported products when servicing tenders from state entities. However, she said it seemed that no one wanted to pay for the SABS to conduct these audits.

SABS CEO Boni Mehlomakulu hit back at industry and the department of trade and industry this week, saying she was fulfilling her mandate according to policy that was implemented in 2005.

She said the issues affecting industry were inherent in the policy, which emerged from the 2004 National Economic Development and Labour Council (Nedlac) report, titled Modernising the South African Technical Infrastructure.

Informed by a department of trade and industry position paper in part authored by Lionel October, who was then the department’s deputy director-general, Nedlac agreed that the SABS should split into a commercial testing and certification entity, and its statutory standards setting body should be funded by government.

The procurement processes for the installation of solar energy systems under the Department of Energy’s (DoE’s) Solar Water Heating programme has not yet started, with no systems installed during the 2015/16 and 2016/17 financial years.
In response to a Parliamentary question, Energy Minister Mmamoloko Kubayi explained that the delay in the installation process was owing to the need to finalise the necessary controls and systems to mitigate the the problems experienced in the previous roll-out model.
Along with a global positioning system verification and tracking system, these included local buy-in from municipalities through the signing of the municipal framework agreement and the identification of the designated installation areas (DIAs) within the municipality, as well as the identification and accredited training of installers in each DIA.
Further mitigation comprised the social facilitation to ensure that the beneficiary community has been exposed to the operational requirements of solar water heater systems, and to align community expectations through the social facilitation platform.
The DoE also confirmed the purchase of 59 396 units as at April 3, 2017, which are currently being stored.

South African rocket scientist Andre Nel has been shortlisted as a finalist in the UK’s Royal Academy of Engineering Africa Prize for Engineering Innovation.
Nel invented a hybrid, solar microgrid solution, the GreenTower Microgrid, which uses 90% less energy to heat water.
​Only one-third of Africans have access to grid-connected electricity and heating water accounts for the majority of electricity costs in homes and offices.
A single unit of the GreenTower Microgrid packaged in insulated recycled shipping containers can service 15 homes, and reduce a community's electricity demand by 65%, considerably easing the pressure on the national power grid.

Association of Municipal Electricity Users (AMEU) strategic advisor Peter Fowles recently issued a warning to municipalities against signing Letters of Intent or similar documents with private companies offering solar water heater (SWH) installations at no cost. He said these offers are made in anticipation of Department of Energy (DoE) funding, but that there is no application process in place at present.
Fowles warned that the 2008 DoE mandate to Eskom to install 1-million SWH systems under a conditional grant had been terminated and that the DoE had instead assumed responsibility for implementing the National Solar Water Heater Programme (NSWHP).
Subsequent to terminating the mandate, the DoE reported at the National NSWHP Workshop for municipalities on 4 September 2015 that roughly 400 000 of the1-million mandated SWHs had been installed in residential areas since 2004.
It said these installations had failed to lower demand as they had been focused on areas of low consumption. The installations were also found to contain predominantly imported components and the installation work was sub-standard. This the department ascribed to a lack of training.
The DoE also said verification of the number and locations of the SWH installations is unreliable as no monitoring had been done. Similarly, maintenance work on installed heaters had been neglected, causing households without electric water heating systems to heat water with kettles, hot plates or wood fires.
