Tibet´s highly subsidised solar heating market

Submitted by Baerbel Epp on April 2, 2018
Tibet is currently in the focus of the Chinese central government’s efforts to improve the heating situation of the population. The lack of space heating in many buildings in the region, which is subject to a continental climate marked by cold winters, has prompted China’s government to support the installation of solar district heating systems. In addition to Chinese-Danish joint venture Arcon-Sunmark Large-Scale Solar Systems Integration, Chinese parabolic trough collector manufacturer Vicot Solar Technology has signed a contract with the local government to install a solar district heating system in the autonomous region of Tibet. The photo, taken in November 2017, shows one-third of the field’s substructure. The entire installation will have 18,000 m2 of aperture area which is defined as the flat, rectangular area specified by the outer perimeter of the mirrors.

Heat pump makes use of low-temperature solar energy for space heating

Submitted by Baerbel Epp on March 29, 2018
Markus BeslmeislWith round about four decades in business, the German-Slovak Thermosolar Group is one of the oldest solar thermal manufacturers in Europe. It began producing collectors in 1972 in Slovakia and started offering a special evacuated flat plate collector in 1997. Last November, long-time sales manager Markus Beslmeisl (see photo) acquired the remaining shares in the company from Johann Kollmannsberger. Solarthermalworld.org spoke with the new managing director about Thermosolar’s special solar heat pump system, called Duo Premium.

“Need to include solar in architectural education”

Submitted by Baerbel Epp on March 28, 2018
Sylvio PodestaBrazil ranks fourth on the list of the world’s largest solar thermal markets, but very few installations have been integrated into a facade or roof. Sylvio de Podestá is the architect behind one of the buildings that have roof-integrated collectors. At this hotel in Belo Horizonte, also known as Brazil’s solar capital, the collectors are at a slope guaranteed to maximise efficiency (see image). Usually, solar systems are added during construction, long after the design stage.

NPV, IRR and DDP: The language of bankers and investors

Submitted by Baerbel Epp on March 27, 2018
Chart: Patrick ReiterIndustry professionals often do not use the same language as bankers and investors when they present solar thermal projects. We have asked Patrick Reiter, who has just finished his master’s thesis, titled Solar District Heating – Economic feasibility of large-scale solar thermal systems in municipal district heating networks – a case from Austria, to explain the most important words and key performance indicators, or KPIs, for the financial feasibility assessment of large-scale solar thermal plants. He studied for his master’s degree at the University of Graz’s Institute of Systems Sciences, Innovation and Sustainability Research.

New export-orientated collector and tank factory in Turkey

Submitted by Baerbel Epp on March 21, 2018
Bural Solar 1Collector and tank producer Bural Solar, founded in 2015, showed its product range at this year’s Mostra Convegno, an international trade fair in Milan, Italy, Mid March. The founder of the company, Hakan Alas, has been working in the solar thermal industry for 20 years. The export-focused business, based in Kayseri, central Turkey, started producing tanks and collectors in 2016. Mostra Convegno, which featured around 2,000 exhibitors, attracted more than 155,000 people, with every forth attendee coming from outside the country. It is 2018’s largest show about heating, ventilation, air conditioning and energy in Europe.

World’s largest flat plate collector manufacturers in 2017

Submitted by Baerbel Epp on March 19, 2018
The 2017 ranking of the world’s largest flat plate collector producers clearly shows the market dominance of Chinese companies. Even second-ranked Greenonetec, an Austrian collector manufacturer, is now majority-owned by the Chinese-based Haier Group. The corporation acquired 51 % of the manufacturer’s shares on 18 May 2017. The largest European flat plate collector producer was heating technology supplier Bosch Thermotechnik, although it remained at a certain distance from the top four. Business at Bosch Thermotechnik suffered from declining solar hot water markets in Germany (-16 %) and Brazil (-18 %). Nearly all the companies outside Germany increased production last year.

Solar thermal and biomass – a winning solution for district heating

Submitted by Baerbel Epp on March 18, 2018
Photo: Riccardo BattistiBiomass may be cheap and carbon-neutral, but a solar upgrade of biomass-fired district heating could further improve efficiency and reduce local emissions. For example, solar heat helps avoid having to start up and shut down wood-chip boilers or operate them at partial load. It can even replace backup fossil fuel systems, which provide district heating networks with energy in summer. During a December 2017 webinar, held as part of the Horizon 2020 project SDHp2m…From Policy to Market, experts from Sweden and Austria showed promising case studies for a clever combination of biomass and solar thermal in district heating.

Financial support for concentrating solar systems extended until 2020

Submitted by Baerbel Epp on March 14, 2018
Photo: HoneywellThe “order” published by the Indian Ministry of New and Renewable Energy on 26 February 2018 put an end to the uncertainty which had pervaded the industry. In the 2-page document, the ministry pledged to continue its investment subsidy programme for concentrating solar thermal systems. The target until March 2020 is 90,000 m² of collector area. The financial year 2017 to 2018, during which 20,000 m² were planned to be subsidised, is almost over.

Molten salt storage 33 times cheaper than lithium-ion batteries

Submitted by Baerbel Epp on March 12, 2018
Cost-effective energy storage is key to transitioning to a low-carbon society. Energy can be stored in the form of heat or electricity. A popular storage method for high-temperature thermal applications is a molten salt tank. Fact sheets created by the German Energy Storage Association, or BVES for short, show that molten salt tanks are around 33 times less expensive than electric batteries when it comes to storing a kilowatt-hour in them.

Flat plate collector sales in China reach a record 6 million m2 in 2017

Submitted by Baerbel Epp on March 10, 2018
2017 saw again an increase in flat plate collector area in China. Newly installed flat plate collector area rose by 13 %, whereas vacuum tube collector area declined by 9 % (see the table at the end of this article). Estimates by CSTIF, the Chinese Solar Thermal Industry Federation, put the size of the 2017 flat plate collector market at 6.03 million m2 (4,221 MWth). Jinheng Solar, a flat plate collector manufacturer based in Dezhou in Shandong province, responded to the positive development by expanding production capacity last year. The photo shows the company’s new automated production lines.
