Three labels in Europe – what are the differences?

Submitted by Baerbel Epp on June 22, 2018
collector labels Solergy (left) and Solar Keymark (centre top) as well as the EU Energy Efficiency label (right)Labels and trademarks should give the end-consumer a clear feedback on the quality and performance of the labelled product. Currently there are three labels available for solar products or solar assisted heating systems in Europe, so there is an increasing need to explain the differences to market players as well as customers. The chart above shows the two voluntary collector labels Solergy (left) and Solar Keymark (centre top) as well as the EU Energy Efficiency label (right) which is obligatory for water, space and combi heaters under the Energy Labelling (ELD) and the Ecodesign (EDD) Directives  since September 2015. 

“Racing down the renewable electricity pathway only”

Submitted by Baerbel Epp on June 17, 2018
Renewables 2018 Global Status ReportThe Renewables 2018 Global Status Report illustrates the sharp difference in growth between the renewable electricity and heat markets. Whereas PV had another record year, with newly installed capacity totalling at least 98 GWp in 2017, up from 75 GWp, and wind its third-best ever, by adding 52 GW, solar heating and cooling increased by only 35 GWth – a 4 % drop compared to 2016. “Transformation is picking up speed in the electric power sector, but urgent action is required in heating, cooling and transport,” was the key message of a press release published by Paris-based REN21. The report, launched at the beginning of June, has been followed by a series of speeches at events in Manila, Paris, Brussels, Moscow, Washington and New York. The press release, translated into 12 languages, has been picked up by media outlets around the globe. 

Rising demand for solar heat in large buildings and industry

Submitted by Baerbel Epp on June 6, 2018
SHW 1By the end of 2017, the market for solar heating and cooling had grown by 472 GWth, which again made it the largest for solar energy in the world. The one for photovoltaic systems gained 402 GWp to become the second-largest, and 5 GWel was enough for concentrating solar power to rank third, according to the latest Solar Heat Worldwide report. The report also highlights the rising use of megawatt-class solar heating and cooling solutions for large public and residential buildings, as well as factories. It was launched at the end of May by the IEA Solar Heating and Cooling Programme (IEA SHC). Lead author is the Austrian research institute AEE INTEC.

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.

Solar industrial heat market – a 2017 survey

Submitted by Baerbel Epp on April 26, 2018
Image: solar-payback.com/suppliers2017 was a record year for systems providing solar heat for industrial processes, since at least 110 large ones adding up to 192,580 m² were put into operation. This has been the result of a survey among around 80 turnkey suppliers currently listed on the SHIP Supplier World Map, created by the international Solar Payback project. The total at the end of 2017 stood at approximately 635 SHIP systems, a 21 % increase over the 525 installations which a similar survey showed in early 2017.

Parabolic trough collector production line shipped to China

Submitted by Baerbel Epp on April 24, 2018
Photo: AbsoliconAbsolicon, a Swedish supplier of concentrating solar thermal technology, has recently delivered its first production line to a Chinese company. The equipment to manufacture parabolic trough collectors, which the Swedish business developed in-house, arrived in China in mid-April. The line is now being set up at Heli New Energy Technology, in the country’s southwestern province of Sichuan. The photo, which dates from December 2016, shows the partners involved in the project after they signed the purchase agreement for the system. Heli New Energy is a joint venture between two Chinese companies, namely Xinkun, a family-owned manufacturer, and Jointeam, an energy project developer.

“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.

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.

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.
