- Malealea Lodge, 30 July 2018
In 2016, Bethel Business Community and Development Centre (BBCDC) installed five 150 litre solar water heaters as a pilot project at Malealea Lodge. After monitoring and evaluating the project for 6 months, a decision was taken by the lodge to install another five systems in 2017, again with BBCDC’S help.2018-07-30 15:23:28
Through monitoring, it was found that the geysers were effective for at least 300 days of the year, and during this time, produced a wholly adequate amount of hot water for the establishment’s guests.
During the rainy season, when a lot of overcast conditions occur, the output of the solar geysers needs to be carefully monitored. When the solar output is not sufficient, staff at the lodge switch back to the original gas geysers as a backup. The system was designed so that the change over is extremely simple.
The savings on gas has been significant due to the ample amount solar radiation the lodge receives for much of the year, and plans are afoot to install another 10 systems in the not too distant future.Khothatso Mpheqeke and Karen Surridge, 30 July 2018
The 18th annual African Utility Week hosted 6 411 attendees over 3 days from 84 countries and 300 exhibitors from 30 different countries. The South African National Energy Development Institute (SANEDI) was one of the exhibitors for the 2018 African Utility week showcasing various projects implemented through SANEDI, including the SOLTRAIN programme.2018-07-30 15:21:57
The African Utility week is an international conference hosted annually, providing the largest gathering of energy and water professionals focused on all aspects of provision of energy services to the African market, where attendees can source solutions, generate business and connect with new and existing energy markets. SANEDI participates at this conference annually, through speaking and/or exhibiting.
This year, various stakeholders approached the SANEDI exhibition stand, many of whom were aware of the SOLTRAIN programme and had benefited from it since the first phase through training, knowledge sharing and networking and system installations. SOLTRAIN promotional material was widely distributed and the project received great interest.Tawanda Mushiri and Samson Mhlanga, 30 July 20182018-07-30 14:55:44
Energy is essential to economic growth and poverty reduction in Zimbabwe and the national drive to eradicate poverty and achieve the Sustainable Development Goals (SDGs) requires skilled professionals to manage and implement energy development projects. While basic knowledge is imparted in the undergraduate program, there is need for specialization to successfully implement renewable energy projects.
The serious energy security challenges being faced by the country point to increased demand for renewable energy experts, preferably at postgraduate level, who would service all sectors related to demand and supply of energy in Zimbabwe.
The academic programme was suspended by the University in 2012 due to dwindling numbers of lecturers and supervisors who were qualified to offer MSc programmes. Recently however, the Department of Mechanical Engineering engaged partners in the region and beyond, to provide qualified complementary personnel as a short-term measure to allow the programme to run while staff development efforts are intensified to support the training of academics in order to attain PhD qualifications in the renewable energy field.
The partners include:
- Africa EU Renewable Energy Co-operation Programme (RECP).
- European Union Energy Initiative
- University of Dar es Salaam
- Technical University of Munich (TUM)
- Makerere University
The purpose of the MSc is to provide high quality postgraduate education in the field of renewable energy so that participants develop proficiency in renewable energy project design, implementation, operation and maintenance, as well as in crucial phases of policy generation. There is also scope for focussed research on renewable energy-related topics.
The re-launched masters degree builds on the Mechanical Engineering Department’s other efforts towards the achievement of the 2030 Sustainable Development Goals, in particular, its participation in the Solar Thermal Training and Development Initiative (SOLTRAIN). Through the initiative, the department will be able to capitalise on the programme’s regional knowledge network, as well as have the use of the SOLTRAIN solar thermal demonstration trailer as well as access to various solar thermal demonstration sites. This will contribute immensely to solar thermal-related learning and research.
The Permanent Secretary of Ministry of Energy and Power Development was the guest of Honour where more than 120 participants attended the launch earlier this year.SOLTRAIN Lesotho, 30 July 2018
In order to create income and ensure future sustainability, the Bethal Business and Community Development Centre (BBCDC), with funding and support from SOLTRAIN, has established a solar thermal company in Mohale’s Hoek and has extended its existing workshop.2018-07-30 14:53:05
The workshop is equipped with the necessary tools for the local assembly of solar thermal systems and the welding of stands.
After a diligent procurement exercise, Adendorff Machinery Mart in Bloemfontein was selected as the preferred supplier of the tools and equipment needed for the new venture due to its wide range of stock and proximity to BBCDC.Prof. E. Matlotse, 30 July 2018
The Botswana Solar Thermal Technology Platform (BSTTP) Meeting, held at the end of May, aimed to pave way for the implementation of the Botswana Solar Thermal Technology Roadmap (BSTTR) which was formulated through the SOLTRAIN project. For this meeting, various stakeholders from different establishments, led by the Department of Energy (DoE), convened to deliberate on how best to achieve the huge tasks which lie ahead as part of the roadmap.2018-07-30 14:43:33
The proceedings started with the Clean Energy Research Centre (CERC) Director who is also the Chairman of the Botswana Solar Thermal Technology Platform (BSTTP), Prof. E. Matlotse, giving a welcome address to participants. He emphasised that the implementation of the BSTTR is a huge task which needs stakeholders to all work together towards achieving it.
He also urged DoE to play an active and leading role to ensure that the government offers the required support, without which the roadmap will not succeed.
The CERC Director then went on to recap the SOLTRAIN project milestones so far, giving more detail about the formulation of the BSTTR and its implementation plan. He emphasised that the formulation process was a rigorous consultative process which involved stakeholders from beginning to end.
He also emphasised the level of international and regional cooperation, in particular, the SOLTRAIN Conference in Namibia last year and the conference in Gaborone earlier this year. In both of these conferences, SOLTRAIN partner representatives from Botswana, Lesotho, Mozambique, Namibia, South Africa and Zimbabwe presented their respective country roadmaps which allowed for a sharing of ideas and experiences, and the opportunity to fine tune the countries’ respective roadmaps.
Prof. A. Obok Opok was also on hand to present the BSTTR to the participants, resulting in some robust engagement on how best to implement the roadmap. The following was agreed with respect to the roadmap implementation:
Fenni Shidhika, Helvi Ileka and Zivayi Chiguvare, 30 July 2018
- Clean Energy Research Centre (CERC) is to coordinate the entire process encompassing implementation, monitoring and control.
- In two weeks following the meeting, the CERC Director was to constitute a National Task Force drawn from the key stakeholders which would be responsible for implementation, monitoring and control of the BSTTR.
- After constituting the National Task Force, the, CERC Director would inform the BSTTP.
- The NTF would then start work by drawing up the terms of reference and scope of work.
The Namibia Energy Institute presented recent Southern African Solar Thermal Training and Demonstration Initiative (SOLTRAIN) activities and promoted solar thermal energy at the International Conference on Solar Power Systems for Namibia (SPSN18) organized by the University of Namibia (UNAM), earlier this year.2018-07-30 14:34:10
The international conference took place in mid May at the Greta Conference Centre, just outside of Windhoek.
It was attended by more than 100 participants, 90 % of whom were science school teachers from various regions in the country. The remainder of the participants were academic staff, both lecturers and senior students, from local and international universities, private industry representatives and some government officials.
The main objectives of the conference were to:
- Create awareness, share and gain the latest knowledge and development trends on solar energy systems
- Discuss the implementation of cost recovery systems
- Educate high school teachers on the use of solar energy systems for economic and social development, and
- Design, construct and test simple solar thermal systems.
- The conference emphasised the role that solar lighting and simple solar thermal systems can play in providing access to basic energy services.
Other important topics included energy access and development of communities, environmental impact of energy extraction, transport and usage, as well as regional energy usage in Africa as a whole, SADC and Namibia, in relation to global energy usage.
The impact of energy access on health, education, and societal well-being was also discussed, along with various other options for its provision.
Staff from the Namibia Energy Institute (NEI), which is the Namibian implementation partner for the SOLTRAIN, demonstrated various types of solar cooker, including solar box cookers, the parabolic cooker and the solar bakery.
Ms. Helvi Ileka presented NEI activities including key outputs from the SOLTRAIN Project such as the Solar Thermal Roadmap, the Center of Competence activities and the results from the monitoring systems.
The Honorable Minister of Mines and Energy, Tom Alweendo, attended the last day of the conference and gave his words of encouragement towards energy access for all in the country. He emphasized the value of cooperation between all the various energy stakeholders including government, the private sector and academia, and encouraged them to work together in order to overcome access challenges.
The Minister, school teachers and all participants at the conference, were impressed with how the solar cookers cooked delicious meals and the effectiveness of the solar bakery, with the school teachers showing interest in knowing more about the design and manufacture of the solar cookers and bakery in order for them to introduce the concepts to their students. Lecturers from UNAM also indicated their interest in introducing the solar bakery concept at UNAM for student research for those studying towards a Master’s of Science in Renewable Energy.
Participants at the conference had the opportunity to taste the delicious chicken wings and potatoes cooked from solar cookers, as well as bread baked from the solar bakery.
Below are some pictures of the participants attended the conference and NEI staff explaining the solar cookers and the solar bakery to the participants and to the Honorable Minister of Mines and Energy, Tom Alweendo.Werner Weiss and Monika Spörk-Dür, 7 May 2018
The installation of solar thermal demonstration projects is an important part of the SOLTRAIN programme’s activities. On the one hand, the installations allow the SOLTRAIN community to apply knowledge gained during the training courses, and on the other hand, to show and demonstrate different solar thermal applications from small-scale systems for single family houses to large-scale systems in industrial applications.2018-05-07 14:28:39
The systems also serve as best-practice examples in order to facilitate broader market uptake.A cumulative 221 solar thermal systems with a combined collector area of 2,393 m² had been installed by end of December 2017 in the six SOLTRAIN partner countries.
638 tons of avoided CO2 emissions
The annual solar yield of all solar thermal systems is 1,834 MWh. This corresponds to electricity savings of 2,017 MWh/a and 638 tons of avoided CO21*), and the figures for the individual countries can be seen in the table below.
The avoided electricity cost corresponds to ZAR 4.3 million based on city of Cape Town tariff in 2015 of 213.90 c/kWh including VAT.
At COP21 (United Nations Climate Change Conference), which took place in December 2015 in Paris it was agreed to respond to the global climate change threat by keeping a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels, and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius. This can be reached by switching from a mainly fossil fuel-based economy to an energy supply system based on renewables, and the figures outlined above demonstrate the contribution of SOLTRAIN to the COP21 Agreements.

University of Botswana’s Clean Energy Research Centre (CERC) hosted a successful SOLTRAIN Conference at the University of Botswana (UB) Conference Centre in Gaborone in early February. The event included tours of solar thermal installations in the Gaborone.2018-05-07 14:00:47
The conference kicked off with an address by the UB VC, Prof. David Norris, welcoming participants from institutions and companies from Lesotho, Mozambique, Namibia, Zimbabwe and South Africa. He expressed thanks to the SOLTRAIN community and assured the project sponsors that his institution would continue to support their efforts going forward.
In his address, Minister of Environment, Natural Resources Conservation and Tourism, Honourable Tshekedi Khama, emphasized the reality of climate change and lauded the practical activities that the SOLTRAIN project espouses which go beyond policy. He acknowledged the positive impact that SOLTRAIN activities had in the SADC sub-region, and expressed his thanks.
Mr. Matthias Radosztics, from the Austrian Embassy, emphasised that climate change is on our doorstep and needs effort from everyone in order to mitigate its negative impacts. He commended the SOLTRAIN country partners for coming together at the event and for taking the opportunity to reflect on project outcomes as well as to share experiences and ideas on taking SOLTRAIN forward.
Mr. Werner Weiss of AEE-INTEC highlighted the cumulative contribution of SOLTRAIN to the COP21 agreement in terms of GHG emissions (please see below for a more detailed article on this). Further, Mr. Kudakwashe Ndhlukula of SADC Centre for Renewable Energy and Energy Efficiency (SACREEE) also thanked the project sponsors and outlined ways in which the country partners might sustain efforts when the project draws to a close.
Other notable contributions included Mr. Nico Snyders, from Namibia’s Ministry of Mines and Energy, sharing Namibia’s solar water heating experiences with their national housing programme which is assisted by up to 50% grants from the SOLTRAIN project. Ms. Karin Kritzinger of Stellenbosch University spoke the SOLTRAIN student bursary scheme and Mr. Ivan Yaholnitsky (BBCDC) and Mrs. Helvi Ileka (NEI), provided their perspectives relating to their institutions’ co-operation on their solar baking project.
Another highlight of the conference was delivered by the Director of Energy and Environment Partnership for Southern and East Africa (EEP), Mr. Wim Jonker Klunne, who provided an outline of EEP’s funding relating to the participating countries’ roadmaps and their respective implementation.Ivan Yaholnitsky, 7 May 2018
In December, BBCDC put up a large advertising sign in Mohales Hoek at the site of BBCDC’s solar energy sales operation. The sign is just next to the main southern highway and enhances the exposure of SOLTRAIN and our solar energy products and services. We call it a ‘Green Lantern’.2018-05-07 13:55:59
In one of their recent newsletters, The Climate Reality Project gave these four suggestions for action on Climate Change, drawing on the work of professional psychologists studying change processes in a systematic way:
- Connect the climate crisis to what’s happening in real communities to reduce psychological distance.
- Make climate action a group experience to promote social norms.
- Talk about what we’re gaining, not what we’re losing, to avoid loss aversion.
- Give your friends real ways to take action to prevent “environmental melancholia.”
I think they are useful, especially in regard to the broader mission of the SDGs and future work of SOLTRAIN in Lesotho and regionally.
We hope the Green Lantern fits this pattern. We need to get SOLTRAIN into each and every far flung community in Lesotho, and demonstrate that cost effective lifestyle and hygiene solutions are available and feasible. Positive social activities and processes will drive adoption and innovation. It is true that we need to lead with benefits and qualitative enhancements rather than costs.
Finally, we need to provide opportunities for more participation. When a solar water heater is put up on a roof, it should not be done by one or two people. Rather assemble a crowd and let everyone pitch in. Throw a party with hot dogs grilled in a solar cooker. Music and food create lasting memories. I call on my colleagues and friends in SOLTRAIN to embrace the above. Let us go out and win it. The Green Lantern is meant to herald of much better times. Hope for humanity.SOLTRAIN Administrator, 7 May 20182018-05-07 13:35:53
The project demonstrated an innovative and unconventional solar energy system that garnered the world’s attention according to NUL’s Mr Anadola T’siu, the designer of the system.
This was not the first time the project had received accolades. In 2016, it won second prize at the International Conference on Solar Technologies & Hybrid Mini Grids to Improve Energy Access held in Bad Hersfeld, Germany, at which it was recognised for its potential for alleviating energy poverty in rural Lesotho.
Dimitri Kerkentzes, Deputy Secretary General of the Bureau of International Exhibitions, lauded the project as a concrete example of the core values of both Expo 2017 Astana and Expo ’90, to promote sustainability and environmental protection. Mr. Shinya Kubota of the Expo ’90 added that the project fully embodies the harmonious coexistence of nature and mankind, the fundamental principle of the Expo ’90 Foundation.
The solar energy system offers traditional water heating for general use, space heating (including under floor heating and wall radiation heating) and can also generate electricity using the Organic Rankine cycle, thus eliminating the need for unsustainable and expensive storage batteries.
A published paper on the system can be found at this link. https://www.researchgate.net/ publication/318344342_Construction_and_ Performance_Evaluation_of_A_Low-Cost_Flat- Plate_Solar_Energy_CollectorHelvi Ileka and Rudi Moschik, 7 May 2018
The Namibia Energy Institute (NEI), at the Namibia University of Science and Technology together with AEE-INTEC, have installed the first photovoltaic water heater (PWH) in Namibia using a special DC/AC element for heating the water. The installation is for research purposes under the SOLTRAIN project.2018-05-07 12:44:18
Through SOLTRAIN, NEI has already installed 62 solar water heaters (SWH) at low cost houses in Windhoek’s Otjomuise township between December 2015 and March 2016.
In addition, measurement and verification systems were installed at six houses, four of which had SWH installed while the other two used electrical geysers, and data has been collected and analyzed at these houses since 2016. The installation of PWH now takes the research a step further.
The PWH installation consists of six solar PV modules with a cumulative 1.59kWp capacity which are connected directly to a resistive element for heating a 300l tank using direct current (DC) without an inverter. The element is also able to operate from the house mains AC supply as a backup for when there is not sufficient sun to power the element with solar.
The PWH system was installed at one of the houses which was previously monitored using a standard electrical geyser. Another house, which also used an electrical geyser and which was also previously monitored, was equipped with a thermosyphon unit consisting of a 300l tank and 4m2 collector. Both systems were designed based on the hot water demand per person in the respective houses as analyzed for one year.
This provides a comprehensive research platform for the comparison of SWH and PWH in Namibia, the results of which will be highly informative for both the housing and energy sectors in the country. In addition, the pilot project also be aims at exploring the possibility of adopting the photovoltaic water heating system in off-grid areas where it could be used to provide basic electricity needs including the provision of hot water.
Senior Shimhanda, a Master of Environmental Engineering student at NUS, with a specialization in renewable energy systems, is working with NEI as an intern to work on the pilot project as part of his final research to complete his Masters thesis. He was directly involved in the installation of the two systems and monitoring equipment, and will also collect and analyse the data.
According to Shimhanda, “it is essential to conduct a techno-economic analysis of the existing water heating systems in the Namibian context in order to determine the best domestic water heating technology between SWH and photovoltaic water heating. The outcome of the research will help prospective Namibian consumers choose the most efficient and cost effective solution between SWH and PWH”.
Shimhanda added that the research into the SWH and the PWH aims to answer the following questions:
- Whether existing water heating systems are viable technically and economically
- Their possible impacts on the environment
- The initial capital costs and operation costs of each water heating system
- Which technology is more cost-effective in terms of performance and economic benefits and;
- Which technology is more efficient and less prone to intermittent weather fluctuations.
Mr Nicolas Marembo, the owner of the PWH system who also contributed to its cost, was trained on the functionality of the system and reports that he is happy with the system so far.Andrew Obok Opok, 7 May 2018
Botswana’s first solar thermal system subsidized by SOLTRAIN was commissioned in February this year. SOLTRAIN’s partner in Botswana, the Centre for Clean Energy Research, University of Botswana, actively guided and supported the project through the phases from inception to installation and commissioning. The beneficiary of the project is Mara-u-Pula Secondary School, which is a premium Senior Secondary School located in the proximity of Gaborone Central Business District.2018-05-07 10:08:56
With a price tag of close to 18,000 Euros, the project timeline took roughly three months from the time of submission of application for the SOLTRAIN subsidy to installation and commissioning, and the design and installation was done by Botswana-based company, So Solar (Pty) Ltd.
Technical Description of the systems
The installation consists of two pumped solar thermal water heating systems. The first is for the boy’s boarding house which was a refurbishment. This system was sized to provide hot water for 65 students and consists of a 2000 litre tank with a heat exchanger and an electric heater as backup. It was designed to operate with a 90% solar fraction and is powered by 16 flat plate collectors in combination of series and parallel. Due to roof orientation, the collectors face north west and consequently, a modest addition to the collector area was needed to compensate for the orientation away from north. The pumped system supplies 1800 litres per day on average.
The second system is installed at the girl’s boarding house and is designed to meet water demand for 65 girls. It consists of a hot water tank of 2000 litres and is powered by 12 flat plate collectors, also connected in a parallel and series arrangement. The collectors face north for optimal solar gain.
To comply with SOLTRAIN requirements, the systems are equipped with remote monitoring capabilities to enable their performance to be tracked on a continuous basis. A number of parametersarecapturedandrecorded,including collector inlet and outlet temperatures, storage tank heat exchanger temperatures across the primary and secondary loops, mass flow rates for the heat transfer media, water glycol mixture for the input and output of the collector circuit and the mass flow rates for the heat exchanger system. More importantly, the solar radiation resource available at the site is monitored continuously to enable the yield, efficiency and economic performance to be evaluated over a desired time-horizon.
Site Visit and Quality Assurance Training
The completion and commissioning of the Mara-u-pula system coincided with two important SOLTRAIN events in Botswana, namely, SOLTRAIN’s annual two-day conference held in early February, and SOLTRAIN’s Quality Inspectors: Solar Water Heating training course which took place after the conference. Conference delegates were taken on a site visit to the installation where they experienced the contribution that SOLTRAIN is making in practice towards promoting and developing capacity in the field of solar thermal systems in Botswana.Puleng Mosothoane, 7 May 2018
SOLTRAIN ran a technical tour late last year and invited representatives from solar companies, academic institutions, the public sector and those who had previously attended SOLTRAIN training sessions to participate.2018-05-07 09:58:05
The 37 participants were treated to a number of interesting site visits which included a range of solar technologies, including BBCDC’s now famous solar cooking technologies.
The technical tour was followed by a dissemination course for 38 participants run by Mr Sehloho Holomo from BBCDC and Mr Anadola Tsiu from the National University of Lesotho, both of whom had attended previous SOLTRAIN train the trainer courses.
Another technical tour will be run in late June this year with another dissemination course happening shortly thereafter.Dr Karen Surridge, 7 May 2018
The SOLTRAIN project aims to tackle water heating energy needs and create opportunities through addressing the solar water heating sector across six partner countries in the Southern African Development Community (SADC), namely, Botswana, Lesotho, Mozambique, Namibia, South Africa, and Zimbabwe, through training, awareness raising, performance monitoring and demonstration systems.2018-05-07 09:10:22
The SA government has realised that a low carbon economy can bring benefits and in particular it will support climate change mitigation measures. The Government has already committed to reducing carbon emissions in South Africa by 34% by 2020 and 42% by 2025 depending on certain conditions. In order to meet these emissions reduction targets, several strategies will need to be used towards meeting this goal.
On the 6th February 2018, SANEDI hosted the launch and discussion of the “Solar Thermal Technology Implementation Plan for South Africa” as part of Phase III of the SOLTRAIN programme. This plan outlines what needs to be achieved in order to meet the SOLTRAIN visionary target to have ½ m² of net solar thermal collector area for every member of the population by 2030 in South Africa.
It is split into 5 “Roadmaps” that essentially outline projected installations needing to be met in order to achieve the goal:
Roadmap 1: High Pressure Residential Solar Water Heating
To grow the installed area to ~12 000 000 m² by 2030, requires a growth rate of 21% per annum on annual installations
Roadmap 2: Low Pressure Residential Solar Water Heating
The South African government has committed to install 600 000 units over two years. For the purposes of this roadmap, it is presumed that this commitment of 300 000 units per year will be sustained up to 2030, to produce a total installation number of 5 200 000 units
Roadmap 3: Industrial/Commercial/ Multi- Family Residential installations for Solar Heating and Cooling
If this market is grown with 40% per year on total installations, there will be 48 848 m² of solar collectors installed by 2030
Roadmap 4: Unglazed Swimming Pool Solar Water Heaters
If this market is grown with 35% per year on total installations, there will be 527 630 installations, or 10 522 598 m² of solar collectors installed by 2030, which represents 65% of the current number of swimming pools in South Africa
Roadmap 5: Passive Solar Thermal (PST) heating/cooling of buildings
It should be noted that solar thermal buildings include at least one day’s integral thermal storage as a result of the prescribed interior thermal mass (SANS10400XA).
Over 50 people from across sectors (industry associations, science councils, private sector, government departments, academic institutions, municipalities, NGOs and State- owned entities) attended this launch and shared in a presentation of the document as well as a lively panel discussion to explore roles in support of the implementation plan for Industry, Government and R&D sectors. Key to achieving this is a focus on awareness and marketing, institutional issues, workforce development (in terms if training and education) and research and development. Valuable points to this end were raised during the panel discussion:
- Knowledge sharing is key and important information must reach decision makers as well as the general public, just as important is coordination between sectoral role players, what is a possible mechanism to achieve this?
- How is government support obtained for this sector and which government department/s should endorse this?
- How is SWH linked to industrialisation and development of the industry in South Africa and what is needed in terms of support by the government? And how can this link to the Special Economic Zones or Industrial Parks initiatives
- What is the local potential for evacuated tube technology in terms of job creation, possibilities of a municipal/government tariff levee, the local and export value chain?
- Should there be research and development with an RRR (reduce, reuse, recycle) focus for the sector?
- How do potential users know what is a good system? Should market competition define this?
- How to approach solutions to testing and certification (energy efficiency rating B) challenges? How to make component testing easier?
- Technology reputation is key to a successful implementation
- Defining a strategy, coordination, knowledge management, awareness, systemic approach and an implementation plan, broader vision
- How to identify and exploit any competitive advantages for South Africa in this sector?
- How to avoid peaks?
- Consider incentives vs. rebates
- How to address and achieve system simplicity?
- The Sustainable Energy Society of Southern Africa (SESSA) has a company list of certified installers and is an instrument for public awareness
- Consider the implications of using PV to reach the defined targets
- Consider the concept of heat ESCos (Energy Service Companies)
It was suggested that SOLTRAIN might explore the possibility of compiling a study on “lessons learned” that focuses on what strategies should not be repeated, showcasing together with learning of successes and failures and how to maintain stability in a solar water heating roll out programme. A further study, might explore the heat technology, area vs. yield, competitive advantages and systems for commercial and industrial application, and to a large extent this is being addressed the Solar PayBack Project being implemented by SANEDI (https://www. solar-payback.com).
In addition to the above, it should be noted that the National Solar Water Heating Programme is in the process of being moved to Central Energy Fund (CEF). One of the sub-programmes under this, the Repair/Replace programme, which is at an advanced stage, has been delegated to the DoE-IPP Office. Additional information, in regard to the NSWHP current status and objectives, can be accessed at https:// solarwaterheating-programme.co.za
Following the launch of the implementation plan document several key stakeholders representing industry, government, research and development were hosted on a site visit to explore some of the SOLTRAIN systems installed in the Gauteng area during SOLTRAIN phases 2 and 3. The aim of this tour was to showcase different types of systems at different scales and their deliverable performance.
Achieving this vision will require an effective, long-term and balanced policy effort to allow for optimal technology progress, cost reduction and ramp-up of industrial manufacturing for mass deployment. The South African Government will need to provide long-term targets and stable supporting policies to build confidence for investment in manufacturing capacity and deployment of solar thermal systems.Monika Spörk-Dür, 31 January 2018A specialised course for a restricted number of experts was held in Stellenbosch at the end of November, giving insight into state-of-the-art design, simulation, planning and installation of advanced high quality solar thermal systems for industrial applications in Southern Africa. The training course was carried out in co-operation with SOLTRAIN and the Solar Academy of the IEA Solar Heating and Cooling Programme, and was hosted and organized by the SOLTRAIN project partner, CRSES, from Stellenbosch University.2018-01-31 06:06:09
The course accepted 50 participants, of which about 12 were planners from the solar thermal industry. The remaining participants comprised SOLTRAIN partners, researchers and members of public institutions. The course was lectured by SOLTRAIN coordinator, Werner Weiss, from AEE –Institute for Sustainable Technologies (AEE INTEC) in Austria, and by Christoph Brunner, head of the Department of Industrial Processes and Energy Systems at AEE INTEC, Austria.
The feedback of participants was unanimous in that they derived great benefit from attending the course, and expressed great interest in any future SOLTRAIN courses.
