China: Solar Process Heat and Space Heating and Cooling Rack Up Market Shares

Submitted by Baerbel Epp on April 19, 2017
CSTIFChina’s shift away from residential towards commercial solar thermal applications continues: The collector area of newly installed solar water heaters in single-family buildings declined by 26 % in 2016, whereas the ‘engineering segment’ remained stable last year (see the table below). This segment is comprised of all non-domestic hot water applications, such as space heating and cooling as well as applications in industry and agriculture. Overall, its share in the newly installed collector area went from 61 to 68 %. All figures were taken from the Report on the State of China's Solar Thermal Industry (July to December 2016), a document drafted by Dezhou-based consultancy Sun’s Vision on behalf of CSTIF, the Chinese Solar Thermal Industry Federation. CSTIF has presented this report – which also includes several development strategies – to the National Energy Board. 
 

Greece: Manufacturers Exporting More Each Year

Submitted by Baerbel Epp on April 18, 2017
Greece ExportDespite shrinking markets in Europe, Greece’s collector and tank manufacturers have increased their exports two times in a row. In 2015, the solar thermal industry delivered 7 % more collector area abroad and in 2016, the figure even rose by 14 % compared to the year prior and totalled 330,000 m² (231 MWth). Main export markets were in Southern Europe, North Africa and the Gulf region. Domestic sales have remained at the same level since 2014, at around 270,000 m² (189 MWth).

Chile: Solar Thermal Market Moves at Half Throttle

Submitted by Baerbel Epp on April 11, 2017
ChileOne year after the relaunch of the tax credit scheme for solar thermal systems in February 2016 (Law 20.897), some preliminary figures show a small increase of Chile’s solar market. But although the subsidy for newbuilds will be in effect until 2020, industry representatives have not been particularly satisfied with the impact of the new legal framework. Their criticism was supported by the fact that the announced subsidy scheme for social housing projects and low-income families has yet to be implemented. The market has improved slightly, but is moving at only half throttle. The photo shows the Villa Verde houses in the coastal city of Constitución. Some of the units which are part of this housing project have a thermosiphon system installed on the roof.

IEA SHC Task 50: LightingRetrofitAdviser.com for Investors and Planners

Submitted by Baerbel Epp on April 6, 2017
IEA SHC Task 50A redesign of lighting systems in office or public buildings helps to save electricity and improve lighting quality, as the office building of the Austrian company Bartenbach on the photos shows. However, lighting systems are rarely upgraded: For example, in Germany, retrofits can only be found in 3 % of the existing building stock and 75 % of lighting systems are out of date, as they are older than 25 years. To support planners and investors in their decision on what would be the most apt lighting retrofit, the researchers of Task 50 of the IEA Solar Heating and Cooling Programme, Advanced Lighting Solutions for Retrofitting Buildings, have launched a website called www.lightingretrofitadviser.com and an app for Android and iOS devices. Both provide stakeholders with information about successful case studies of lighting retrofits in buildings, a database of technologies as well as tools, for example, to give direct onsite support for decision making, whether it is sensible to retrofit a lighting system. A webinar on 21 March explained all the services and features of the new website and app. A recording of it is available online.

ISH in Germany: Easy Selling – Heating Industry Starts Digital Marketing Journey

Submitted by Baerbel Epp on April 5, 2017
Junkers ISH 2017Traditionally, the ISH has been the biannual forum for the European heating industry to showcase product innovations and new business strategies. The big five in Europe – Bosch Thermotechnik with its brands Buderus and Junkers, Viessmann, Vaillant, Ariston and its Elco brand, and BDR Thermea with its brands Remeha, Brötje and De Dietrich – welcomed tens of thousands of installers to the international five-day business-to-business fair in Frankfurt, Germany, at the beginning of March 2017. They chose two entirely different ways of presenting the new generation of heating solutions: Viessmann and Junkers focused on online marketing and sales, whereas Vaillant and Buderus favoured system integration. “Easy selling” reads the exhibition wall at the booth of Junkers (see photo), where the new online marketing tool was shown to attendees.

Tunisia: National Subsidy Scheme Prosol Extended to 2020

Submitted by Baerbel Epp on April 3, 2017
Tunisian Market DevelopmentTunisia`s solar thermal market stabilised at 64,000 m2 in 2016, a figure only slightly lower than the 65,000 m2 in 2015 and in 2014, but significantly below the peak years of 2008 to 2010. The key market driver had again been Prosol, the national residential programme launched in 2005 and based on a financial scheme combining direct subsidies of Tunisian Dinar (TND) 200 and 300 granted by the Energy Transition Fund and low-interest loans. With 90 %, residential systems still account for the largest share in newly installed collector area. However, hotels and commercial buildings have profited from Prosol Tertiary since 2009 and contributed around 5 %.

Europe: Comparing Solar Keymark Data on Collectors with Foil or Double Glass Cover to Ones Without

Submitted by Baerbel Epp on April 3, 2017
KBB large-scale collectorDenmark’s success story in solar district heating, with 2016 having been another record year which almost doubled newly installed collector area to around 500,000 m², showcases the large potential of this type of application across Europe. Cost cuts in the supply chain are key: Two vital factors are fast installation and less hydraulic work on site. The answer by manufacturers to these challenges has been to design large-scale prefabricated collectors. Suppliers of vacuum tube collectors offer modular designs for easy mounting of collectors above 10 m²; large flat plate versions come as one piece and certified by Solar Keymark. The yearly market surveys by German magazine Sonne Wind & Wärme show that the number of certified flat plate collector panels above 10 m² of gross collector area has increased in Europe in recent years. As of 29 March 2017, the magazine’s online collector database listed 62 models from eight brands compared to 20 types of collectors in October 2015.

Jordan: Four Demonstration Plants for Solar Air Conditioning Commissioned

Submitted by Baerbel Epp on March 29, 2017
Petra Guest House JordanJordan is showing rapidly increasing demand for air-conditioning. Total annual emissions from cooling commercial buildings add up to 600,000 tonnes of CO2, an amount equal to emissions from about 120,000 passenger vehicles per year. This has prompted the German Agency for International Cooperation to initiate the project Solar Cooling in Industry and Commerce in Jordan. The German Technische Universität Berlin (TUB) played a key role in this transfer of technology and know-how for the planning and installation as well as monitoring of four solar-driven air-conditioning systems in public and private buildings. The photo shows the 388 m² collector field which was commissioned at Petra Guest House in February 2015, around the same time as the one at German Jordanian University.

ISH Trade Fair: Not Much on Solar Heating

Submitted by Baerbel Epp on March 27, 2017
ISH 2017 Eva AugstenWith more than 200,000 visitors from 61 countries and 2,482 exhibitors, this year´s ISH trade fair in Frankfurt, Germany, set a new record. The biannual exhibition showed the latest trends in building and heating technologies, including renewable energy applications. During the one-hour press conference of the German heating industry association BDH, the world “solar” was not even mentioned once. Faced with decreasing interest in solar thermal across central Europe, the portfolio of the few exhibitors specialising in the technology included electric heating in one way or another. The photo shows a collector to regenerate boreholes which are connected to heat pump.
