Solar cooling increases annual solar fraction

Submitted by Baerbel Epp on February 24, 2018
Task 53 1Solar cooling could be an effective way to increase the annual solar fraction of domestic hot water production and prevent the solar system from overheating in summer. Under the aegis of the IEA Solar Heating & Cooling Programme, researchers from Task 53, New Generation Solar Cooling & Heating Systems, have written a new book, titled The Solar Cooling Design Guide: Case Studies of Successful Solar Air Conditioning Design. It includes a detailed case study of two buildings containing offices and flats in Montpellier, France. The on-site 240 m² flat plate collector system powers a 35-kW absorption chiller to achieve a 70 % solar fraction in annual hot water production (see photo). Between November and March, the system continues to provide around 40 % of the heating energy to meet hot water demand.

Germany: Solar thermal loses out to other renewables

Submitted by Baerbel Epp on February 20, 2018
Wagner & Co2017 was the weakest year for solar thermal collector sales in more than a decade, according to the combined statistics by associations BDH and BSW-Solar. Their data reveals that only 78,000 systems were sold last year. The newly installed collector area added up to 625,000 m², down 16 % from 2016 and as much as 72 % from the boom year of 2008. It was an astonishingly poor showing, considering the strong growth in the construction industry and the high incentive amounts available in Germany.

Indian manufacturers face strong competition from Chinese imports

Photo: Jaideep N. MalaviyaVacuum tube-based solar water heaters imported from China are posing a serious threat to the viability of domestic manufacturing in India. This was the key message from the STFI, the Solar Thermal Federation of India, at a mid-January consultation meeting of the Parliamentary Standing Committee on Commerce. The committee had invited several stakeholders to attend the meeting to discuss the Impact of cheap Chinese consumer goods on the Indian industry. Nowadays, three of every four solar water heaters are imported from China, resulting in a loss of local employment.

Daylight and electric lighting: new research initiative

Submitted by Baerbel Epp on February 14, 2018
Task 61The IEA Solar Heating & Cooling Programme has approved Task 61, a new research initiative concentrating on integrated daylight and electric lighting solutions. The task will tackle unresolved issues and challenges of a growing market which meets 19 % of the total electricity demand around the world. It will launch with a 3-day workshop from 28 February to 2 March 2018 in Lund, Sweden. Experts with a background in R&D or manufacturing are welcome to join the initiative.

IKEA stores begin to switch over to solar heating and cooling

Submitted by Baerbel Epp on February 13, 2018
Ikea SingaporeIKEA, one of the world´s biggest home furnishing retailers, has demonstrated a strong, long-term commitment to climate protection. By 2020, the company intends to generate as much energy from renewables as it consumes in day-to-day operations. While most of the electricity is now generated from renewable sources, IKEA’s store managers have not lost sight of the heating part of the equation. Two locations, one in Singapore (see photo) and one in the Russian Omsk region, have recently announced the completion of new solar heating and cooling installations.

CBENS to discuss solar heat for industry

Submitted by Baerbel Epp on February 12, 2018
CBENS 2018Brazil’s solar energy association ABENS has invited about 500 experts to the solar energy conference CBENS taking place from 17 to 20 April 2018 in Gramado. This year’s event, held in the south of the country, offers a round-table discussion about solar heat for industrial processes, or SHIP for short, to raise awareness among technicians, researchers and future professionals of a technology that many in Brazil know little about.
 

State-of-the-art collector production in Uzbekistan

Submitted by Baerbel Epp on February 9, 2018
gazeta.uzLast November, Uzbek-based Artel Group gave a tour of its new collector and tank production facility in the capitel city Tashkent. It houses the manufacturing lines for selectively coated and laser-welded collectors traded under the brand name Royal. Stainless steel tanks insulated with polyurethane foam and holding between 300 and 1,000 litres complement the business’s product portfolio. Turkish manufacturer Solimpeks has been advising the company on design matters since 2016.

SHC industry roadmap for Australia

Submitted by Baerbel Epp on February 8, 2018
Despite Australia’s high levels of solar irradiation and rising energy costs, its solar heating and cooling market has been in decline each year since 2010. The newly installed glazed and unglazed collector area went from a peak of 1.14 million m2 in 2009 (798 MWth) to 544,670 m2 in 2016 (381 MWth) – less than half of what it used to be. Reversing the downward spiral is the aim of an industry roadmap, titled Solar Heating and Cooling in Australia´s Built Environment, which was commissioned by ARENA, the Australian Renewable Energy Agency, and is currently under review. During an internal workshop in Abu Dhabi last November, Australian-based consultancy Coolgaia discussed the findings from the roadmap with solar cooling experts working on Task 53 of the IEA Solar Heating and Cooling Programme (see photo).

Solar to replace coal in Polish district heating networks

Submitted by Baerbel Epp on February 7, 2018
NFOŚiGWZbigniew Kamieński, adviser to the president of NFOŚiGW’s board, has recently made some encouraging statements. During the conference Use of renewable energy sources and seasonal heat storage in district heating in Warsaw on 17 January, he said that the proposal of a new subsidy programme for renewable district heating deserved attention and implementation. The conference with nearly 130 attendees was organised jointly by NFOŚiGW, the National Fund for Environmental Protection and Water Management, and IEO, the Institute for Renewable Energy, and was supported by the SDHp2m project
