Germany: First Record-Size Solar District Heating Plant in 11 Years

Submitted by Baerbel Epp on September 27, 2016
Senftenberg GermanyFriday, 23 September 2016, was the inauguration date for the now largest solar thermal collector field in Germany. Since then, 8,300 m² of vacuum tube collectors (5.8 MWth) set up in the town of Senftenberg, 140 km south of Berlin, have been feeding energy into the municipality’s district heating network. The previously largest field since 2005 – a 7,100 m² flat plate collector installation (5.1 MWth) – is located in the southern German town of Crailsheim. The new Senftenberg solar field was designed, manufactured and implemented by German system integrator Ritter XL Solar. The 1,680 collectors, the heat transfer unit and around 6,600 m of pipework were installed within record time: All in all, the project took only six months. The general contractor for the EUR 4.5 million investment was Berlin-based E&G Energiebau, which had received support from the Integral Project, the company responsible for sizing and integrating the solar heat into the existing network.

Turkey: Production Stop at Ezinç in Kayseri

Submitted by Baerbel Epp on September 25, 2016

Turkey dominated the headlines of daily news channels this summer, especially after the tumultuous coup attempt between 15 and 16 July and the purges that followed. But even before, at the end of June, news from Turkey had taken the solar thermal industry by surprise: Ezinç Metal had stopped producing at short notice. Without any prior announcement, management had laid off almost all workers and had closed down the collector and system production within just a few days in June, former employees reported.

District heating: “The industry is very optimistic about its future prospects”

Submitted by Baerbel Epp on September 23, 2016

Ralf Roman SchmidtDistrict heating has a long history in Scandinavia: The international symposium on district heating was launched there in 1987. In the meantime, the technology has reached the global stage and the 15th International Symposium on District Heating and Cooling was the first one supported by the IEA District Heating and Cooling programme (IEA DHC). Dr Ralf Roman Schmidt had been invited to speak at this two-day conference held in South Korea in September and attended by more than 200 people. The research engineer from the AIT, Austrian Institute of Technology, is about to become Austria’s alternate country representative within the IEA DHC.

Soltrain West AfricaApproved and successful policies should be promoted – which is why the Southern African Solar Thermal Training and Demonstration Initiative (SOLTRAIN) should be implemented in West Africa as well. Since 2009, the programme has helped train about 2,150 people during 80 courses and install 187 solar thermal systems in the five partner countries Lesotho, Mozambique, Namibia, South Africa and Zimbabwe. The coordinator, Austrian organisation AEE INTEC, and the implementing body, ECREEE – ECOWAS Regional Centre for Renewable Energy and Energy Efficiency based in Cabo Verde, have now launched a similar four-year training and demonstration programme, SOLtrain West Africa, to increase SWH numbers in five additional countries: Burkina Faso, Cabo Verde, Ghana, Nigeria and Senegal.

India: Industry Demands Equally Assertive Solar Thermal Publicity

Submitted by Baerbel Epp on September 20, 2016
India REI 16 PanelThe Indian government should provide the same assertive publicity for solar thermal technology as it had for solar PV because the population still needed to be made aware of the benefits of solar water heating. This was the major concern raised during the panel discussion Policy and Regulatory Framework for Solar Water Heater Market Development in India moderated by Jaideep Malaviya (third from right), Secretary General of the Solar Thermal Federation of India (STFI). Five industry representatives took part in the event held during the Renewable Energy India Exhibition and Conference 2016 near New Delhi at the beginning of September (from left to right): Rigal Patel (Redsun Solar), Bhoovarahan Thirumalai (Aspiration Energy), Devinder Kaushal (Inter Solar Systems), Saurabh Bhandari (Solarmaxx) and Chandrakant Shah (Kosol Hiramrut Energies).

Austria: Prefabricated Roofboxes Create New Living Space on Multi-Storey Building Roofs

Submitted by Baerbel Epp on September 19, 2016
Haas Fertigbau ModulhausRenovating multi-storey buildings can be used to create new living space with an additional top floor. That’s where an Austrian consortium led by AEE INTEC comes in: It has developed the Roofbox, an entirely prefabricated modular living space. A Roofbox consists of a bathroom, a kitchen, a separate toilet or living room and bedrooms, and it can be ordered with an active solar water heater system already installed on its roof. Every Roofbox can be transported by an articulated lorry and is rigid enough to be lifted by crane for roof mounting. On 16 September, Austrian Haas Fertigbau showcased in its Großwilfersdorf factory a flat made up of two Roofbox prototypes – which, however, is still missing the solar thermal unit on top (see photo).

IEA SHC: Attractive Solar Solutions for Urban and Landscape Planning

Submitted by Baerbel Epp on September 15, 2016
Case Studies Task 51How can urban planners be convinced to consider solar energy technologies in municipality projects? This is the key challenge faced by the international group of researchers of Task 51, Solar Energy in Urban Planning. One way to attract interest from these planners is to present them with case studies of successfully implemented solar projects. So the members of Task 51 headed by Maria Wall, Professor at the Energy and Building Design department of Sweden’s Lund University, have collected around 40 solar case studies and are about to design a brochure for all of them. The authors distinguish between three types of studies: new urban areas, existing urban areas and landscapes.

CBC Installation South AfricaSouth Africa’s solar process heat installations remain profitable when they have to compete against other heat sources, such as diesel, paraffin, petrol or gas, the Centre for Renewable and Sustainable Energy Studies (CRSES) at Stellenbosch University, South Africa, has concluded in a recently published paper. The researchers at the CRSES conducted a feasibility study of a 120.7 m² collector field that was to cover 60 % of the existing hot water requirements of Cape Brewing Company (CBC) based in Suider-Paarl, Western Cape, and analysed ten proposals submitted after the company’s invitation to tender in January 2015. South African E3 Energy won by offering an installation with a levelised cost of energy of 7.9 EUR cents/kWh, an internal rate of return of 16.7 % and a payback period of 9.3 years. CBC´s daily hot water demand is estimated to be 7,000 litres at 85 °C during 245 days a year, i.e., during a full year except for weekends, public holidays and two weeks of summer holidays. The system went into operation in November 2015 and the COO of CBC, Andy Kung, seems satisfied with the performance and the energy saving it offers.

India: Tax Reform May Lead to System Price Increases

Submitted by Baerbel Epp on September 6, 2016
Gujarat Borosil Glass WorksIn India, there are multiple indirect taxes levied on most transactions. These taxes are divided into those collected by the federal government and the ones collected by state authorities. At the beginning of August, the Indian parliament passed the Goods and Services Tax (GST) Bill, which aims for a radical overhaul of the country’s tax system by merging federal, state and local taxes and turn India into a “single-tax” country. The GST is expected to improve the way business is conducted, make foreign investment more attractive and increase the gross domestic product by between 1.5 and 2 %. But the renewable energy industry may take a hit, according to statements from members of the Solar Thermal Federation of India (STFI). All tax incentives will end under the new GST regime, which is to be implemented by 1 April 2017.
