Renewable Global Futures Report: Experts Divided on Future of Heating

Submitted by Baerbel Epp on July 5, 2017
CoverIs the transition to 100 % renewables at global level a feasible and realistic objective? What share will renewably sourced heat have by 2050? Will the electrification of heat continue? These are three of more than 100 questions which were answered in interviews with 114 experts from all around the world. Interviewees came from NGOs, research institutions, governmental bodies and international organisations. REN21’s Renewable Global Futures Report published in April 2017 summed up their explanations as part of twelve Great Debates. Lead author Dr Sven Teske from the University of Technology Sydney, Australia, presented some of the key findings of the report during a June webinar organised by the International Solar Energy Society. 
 

Turkey: Vacuum Tubes in Residential, Flat Plate in Commercial Segment

Submitted by Baerbel Epp on May 19, 2017
Turkey ApplicationTurkey’s solar thermal market remained strong in 2016. However, sales figures are hardly easy to come by, as there is a formal market, on which businesses offer well-known brands, and an informal one, on which systems are supplied by unregistered small producers. Solar Thermals: Turkey, the latest report on the Turkish market by British consultancy BSRIA has shown that the formal market remained fairly stable last year, with an estimated 1.53 million m² (1.1 GWth) compared to 1.5 million m² in 2015. Owners of residential one- and two-family buildings again accounted for the lion’s share of purchases, as 51 % of all new systems for hot water preparation and a small but growing number of space heating systems were sold to them last year (see the chart above).

Brazil: 2016 Market Statistics by Newly Founded Industry Association ABRASOL

Submitted by Baerbel Epp on April 30, 2017
Brazil Market Development 2016A recently introduced annual statistic by Brazil’s newly established industry association ABRASOL based in São Paulo shows that in 2016, the country was again the one with the third-largest number of new installations and the largest solar thermal market in South America. The 1,304,922 m² of newly installed glazed and unglazed water collector area (0.91 GWth) added in 2016 have put it only slightly ahead of India and behind China and Turkey. Brazil’s glazed collector market experienced a comparatively small drop of 4 % considering the country’s ongoing economic and political crisis and the slowdown of Minha Casa Minha Vida (My house, My Life), the programme which had made solar water heaters a requirement for new social housing projects. Reduced purchasing power led to a 10 % decline in the sales of unglazed collectors for swimming pools and vacuum tube collectors played only a minor role last year, garnering 2 % of sales.

Germany: Troubling Times for Wooden In-Roof Collectors

Submitted by Baerbel Epp on April 24, 2017
wooden-frame solar collectorsWooden-frame solar collectors installed by the German cooperative BUSO Bund Solardach may have been the cause of at least 11 fires in 2015 and 2016, listed by solarsicherheit.com. It looks as if fire broke out during collector stagnation. BUSO, a cooperative of about 100 solar installers, was one of the pioneers of solar roof installations in Germany. It used collectors produced by Buschbeck, a company which went bankrupt last year.

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. 
 

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.

USA: Commercial Systems Dominate Californian Solar Thermal Market

Submitted by Baerbel Epp on March 24, 2017
California Incentive ProgrammeThe California Solar Initiative (CSI) – Thermal Program seems to have stabilised at around 20,000 m² (or around 200,000 ft²) of subsidised collector area per year. Commercial applications dominate the statistics, although there was a spike in the share of residential systems in 2016. The peak in applications for commercial pool heating in 2014 was due to the late addition of this type of system to the state subsidy scheme. It took almost a year before the level of incentives and other requirements were set, so that all the applications piling up over that period had to be processed in 2014. The data in the chart was provided by the California Public Utilities Commission (CPUC) and shows the subsidised and installed collector area for each year.

Belarus: 287 Completed Systems Prove Growing Interest in Solar Heat

Submitted by Baerbel Epp on March 16, 2017
The use of solar heat is becoming increasingly popular in Belarus, an eastern European country with around 10 million population. Official statistics from the Ministry of Energy put the number of systems installed across the country at 287; their combined collector area, however, has not been recorded. This article presents a selection of the solar thermal systems partly in residential use, but some have also been integrated into the facade of commercial buildings (left photo) as well as educational and healthcare facilities (right). Their collector size ranges from 4 to 100 m2.

Lebanon: On Track for 2020 Square-Metre Target of 1 Million

Submitted by Baerbel Epp on March 3, 2017
NREAP LebanonLebanon seems to be one of only a handful of countries that are on track for meeting their solar thermal targets. The market statistics from the Lebanese Centre for Energy Conservation (LCEC) show around 250,000 m² of collector area were installed between 2009 and 2014, which exceeded the government’s aim of 190,000 m² for the same period. The second target set in 2009 – a collector area of 1 million m² by 2020 – is just as realistic, LCEC confirmed in its recently published National Renewable Energy Action Plan (NREAP) for the Republic of Lebanon 2016-2020 (see the attached document). The chart shows an estimated market increase of 600,000 m² between 2016 and 2020. The LCEC researchers and authors of Lebanon’s second NREAP also underline the importance of continuing the country’s financing mechanism.

Macedonia: National Subsidy Budget Raise

Submitted by Baerbel Epp on February 14, 2017
Macedonia Incentive ProgrammeThe Republic of Macedonia has been in a state of political turmoil for some time. The most recent general election was held in December 2016, but it is still unclear whether a new government can be formed. Considering the circumstances, the provisional authorities have taken laudable steps to maintain a sense of continuity when it comes to national renewable energy policy. In late January, the Ministry of Economy extended the Programme for partial subsidising of purchased and installed solar thermal collectors in households. “This scheme has been a success since its implementation in 2007 and attracts broad interest,” the country’s economy minister, Driton Kuchi, explained on TV Nova on 7 February. Online news portal Tochka reports that between 2007 and 2016 (see the chart above), the programme supported 4,237 households with a total of Macedonian Denar (MKD) 54 million (around EUR 900,000).
