A survey of the global market for concentrating collectors

Submitted by Baerbel Epp on June 1, 2018
Graphic: Solar PaybackConcentrating collector technologies are becoming an increasingly popular choice for customers requiring industrial heat or space heating. This year’s Renewables 2018 Global Status Report includes, for the first time, data regarding new installations of concentrating systems. Published at the beginning of June by the Paris-based REN21 network, it states that a minimum of 143 MWth was set up in 2017. The largest markets were Oman (100 MWth), China (15 MWth), Italy (14 MWth), India (2.8 MWth) and Mexico (2.8 MWth). The image shows the three technologies available for sale.

“Contract market fluctuates from year to year”

Submitted by Baerbel Epp on April 17, 2018
Ole Dalby, CEO of Arcon-Sunmark2017 was a difficult year for solar district heating supplier Arcon-Sunmark based in Denmark. The collector manufacturer’s turnover dropped from Danish Krone (DKK) 457 million, or USD 75 million, to DKK 98 million, or USD 16.2 million, according to a press release published on 21 March 2018. The uncertain country’s energy policy caused a delay in the launch of new SDH projects in the second half of 2016. Consequently, pre-tax profit went from DKK 46 million (USD 7.6 million) in 2016 to minus DKK 99 million (USD 16.3 million) in 2017. “We have made the necessary adjustments. At the same time, we have invested in retaining the clear market leader position that we achieved over the years,” Ole Dalby, CEO of Arcon-Sunmark (see photo), said.

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.

Photo: Task 55A contract to set up a solar district heating network in Langkazi county in Tibet has been awarded to Arcon-Sunmark Large-Scale Solar Systems. The Chinese-Danish joint venture signed an agreement with the local government of the autonomous region of Tibet. The system should provide solar district heating for 82,600 m² of floor area and meet 90 % of the yearly space heating demand in Langkazi, the town sharing its name with the county. The system, planned to be set up by November, will consist of a 22,000 m² collector field, 15,000 m³ of pit storage and a 3-MW electric boiler. The sponsor of the pilot project is China’s central government.

China: Sunrain Finalises Strategic Cooperation Agreements

Submitted by Baerbel Epp on June 30, 2017
Natural Ressources CanadaThe Chinese Sunrain group, the world’s biggest collector manufacturer, is broadening its product portfolio to include large-scale solar thermal plants. Sunrain had already made the first step towards globalising its strategic partnerships by establishing a joint venture with Danish-based Arcon-Sunmark in June 2016. It has now concluded a cooperation agreement with CanmetEnergy in Canada with the aim to develop solar district heating systems using borehole heat storage fields for seasonal storage in China. Canada’s Minister of Natural Resources Jim Carr (back row 2nd from left) oversaw the signing of the agreement during his visit to China in June 2017. The agreement was signed by Xinjian Xu, Founder and Board Chair of Sunrain Solar Energy (front right) and Frank Des Rosiers, Assistant Deputy Minister of Natural Resources Canada’s Innovation and Energy Technology (front left).

IEA Task 55: Solar District Heating Means Big Business

Submitted by Baerbel Epp on May 23, 2017
Task 55Solar district heating is attractive business. Not only does this become obvious when looking at the 347 MWth of newly installed SDH capacity in Denmark in 2016, but also when one hears about Big Solar, a 250 MWth collector field – with 1.8 million m² of seasonal storage – planned to cover 20 % of the energy demand in the Austrian city of Graz by 2020. It certainly explains the high interest in international research platform Towards the Integration of Large SHC Systems into DHC Networks, or Task 55 of the IEA Solar Heating and Cooling Programme. “We welcomed 33 participants from eight countries during our second project meeting in Aalborg in mid-March, and even had to limit the number of participants per company because of the huge demand,” explained Sabine Putz, Operating Agent of Task 55 and COO and Head of R&D at S.O.L.I.D.

Final Report: Zhengga Village Solar Water Heater and Sanitation Household Bathroom Project (2012)

Submitted by Raquel Ponte Costa on June 7, 2012

This report outlines a small-scale project undertaken in Tibet’s Zhengga Village, which provided a solar water heater and bathroom to each of its 97 households (and their 430 inhabitants). With the Community itself raising 179,450 Chinese Yuan (€22,391) towards the project, the Tibetan Development Assistance Trust provided 194,000 Chinese Yuan (€24,202) to the Lotus Charity Association to allow its realization. The project was implemented from April-December 2011, and was fully successful.
