The Moldovan Agency of Energy Efficiency (AEE) and the country’s Ministry of Economy have jointly announced a tender invitation to companies which would like to start their own solar collector production in Moldova. According to a news article published on 28 September on Russian Mail website mail.ru, the invitation will be made in mid-October. The project will be funded by the Moldovan government as well as a private investor. The map shows the country of Moldova, which is situated between Romania and Ukraine and has a population of around 4 million.
Last year, Chinese vacuum tube manufacturer Huang Ming internationally known as Himin Solar installed its largest system for solar process heat to date. The company said that it had set up a 9,903 m² installation in Shandong province in October 2015, a system which had since produced heat for a textile factory owned by the Ruyi Group. The RMB 12.46 million (EUR 1.66 million) project had been entirely financed by the customer, which had not received any public subsidies. Ruyi had had the plant built because of a lack of electricity. “The local government had restricted electricity supply to Ruyi, which meant that the business could no longer fulfil its annual output targets,” stated a press release by Himin.
Topping out a new primarily solar-supplied residential building in Germany is not really news anymore, especially because there have already been more than 1,800 solar houses set up all across the country, according to November 2015 statistics by the association Sonnenhaus-Institut (Solar House Institute). What’s special about this topping out ceremony on a solar house in Schmölln in the region of Thuringia at the end of August 2016 is the fact that the investor is a bank. The building is planned to cover 55 % of its heat and 100 % of its electricity demand by solar. With it, local cooperative bank VR Bank Altenburger Land wants to demonstrate to its members and clients what smart living will look like in the future.

The 4th International Solar District Heating (SDH) Conference, which had been organised under the auspices of Horizon 2020 project SDHp2m…from Policy to Market on 21/22 September 2016 in Denmark, showed the importance of analysing real-life monitoring data from European SDH plants, with one conference session (Advanced SDH systems II) dedicated exclusively to the topic. These kinds of comparisons enable an understanding of the actual performance of such large collector fields and offer an opportunity for optimising power output and for creating best-practice examples of new plants. For example, the chart displays ten years’ worth of monitoring data from the German plant in Crailsheim, which has met solar yield expectations.

LED technology has greatly changed the face of the lighting market: In just a few years, lighting systems have become twice as efficient and half as expensive. These changes have resulted in a large but often untapped cost- and energy-saving potential in commercial buildings. The research in Task 50 of the IEA Solar Heating and Cooling programme, Advanced Lighting Solutions for Retrofitting Buildings, has shown that the lighting industry is increasingly exploring opportunities for the use of contracting instead of leasing solutions to convince customers of retrofits. According to Marc Fontoynont, Professor at the Department of Energy Performance at Aalborg University, Denmark, and subtask leader of Market and Policies, there is a growing number of specialised companies which offer contracting models for lighting solutions, such as Austrian manufacturer Zumtobel has done with its contracting plan Now! (see chart). All in all, these contracting solutions are less complex than the ones for heat.
Merging three individual conferences into the International Conference on Solar Technologies & Hybrid Mini Grids to Improve Energy Access was rewarded with a satisfying number of attendees visiting the latter. According to the organisers, 185 experts from 38 countries from all corners of the globe met in the small town of Bad Hersfeld near Frankfurt, Germany, in mid-September 2016 to talk about all the technology and market requirements for increasing solar deployment in developing countries. The conference schedule was, of course, fairly focused on photovoltaics, but Southern Africa was well represented, as experts from the partner countries of SOLTRAIN (Southern African Solar Thermal Training and Demonstration Initiative) presented their work during the event (see photo).
While the solar thermal industry has had a difficult time in several EU countries, the solar district heating (SDH) community is still growing: 180 participants from the EU, South Korea and China attended the 4th International Solar District Heating Conference, which was held at quite the peculiar location this year – Denmark’s Legoland – and was organised under the auspices of the Horizon 2020 project SDHp2m…from Policy to Market. The introductory session of the conference was really inspiring. Thomas Pauschinger, Project Coordinator of SDHp2m, underlined how Denmark’s construction of plants in the 100 MW range was proof of the country’s solar thermal strategy of “think big”. Impressive results, even more so if one takes the statement by Kim Behnke, Deputy Director General of Dansk Fjernvarme, the Danish District Heating Association, into account that “the Danish solar dream started just ten years ago”. Denmark’s solar installations have become so famous that they have even been turned into brick models at Legoland. The photo shows the 13 MW solar field in Braedstrup, Denmark.
Friday, 23 September 2016, was the inauguration date for the now largest solar thermal collector field in Germany. Since August, 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 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 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.
