South Africa: Incentive Programme Nears Government Approval

Submitted by Baerbel Epp on June 28, 2015
SESSAUntil recently, the solar water heater (SWH) rebate programme of state-owned power provider Eskom had been a key element in South Africa´s endeavour to cope with continually unstable power supply and become a more environmentally friendly society. Eskom granted refunds to customers replacing conventional geysers in households and commercial buildings with solar thermal ones. The result: 85,000 high-pressure solar water heaters funded by the rebate programme since 2008, according to estimates by the Sustainable Energy Society of Southern Africa (SESSA). The non-governmental organisation representing the local solar thermal industry wrote in its weekly newsletter, Energy Fix – Week 21, that 330,000 low-pressure systems were installed from 2010 until the end of 2012.

Italy: Solar Thermal Municipalities Growing in Number

Submitted by Baerbel Epp on June 25, 2015
Solaretermico Municipality ItalyLegambiente, one of the major environmental associations in Italy, releases a report every year on the diffusion of renewables at local level, highlighting the role of municipalities and stressing their commitment, for instance, to renewable use in public buildings (see the attached document in Italian). For nine years, this report titled Renewable Municipalities (Comuni Rinnovabili in Italian) has shown maps, rankings and best-practice examples to illustrate the deployment of the different clean technologies: The current study, published in May 2015, listed 6,803 Italian municipalities with solar thermal installations from a total number of about 8,000 in 2014. This represents a huge increase from the 108 municipalities having solar water heating installed in their community in the first survey in 2005. The map displays the cumulated solar capacity at regional level at the end of 2014, with the red areas pointing to broad solar water heater usage.

Worldwide: Rough Estimates Say between 0.5 and 2.2 Million Solar Heating and Cooling Jobs

Submitted by Baerbel Epp on June 23, 2015
IRENA job pie chartData on the number of solar water heating and cooling jobs differs greatly from publication to publication. According to the annual study Renewable Energy and Jobs – Annual Review 2015 by the International Renewable Energy Agency (IRENA), there were approximately 764,000 people employed in solar heating and cooling globally in 2014, 16 % lower than in 2013 because of the market decline in China. The pie chart shows the distribution among the main markets. The Solar Heat Worldwide 2013 report, published in June 2015 by Austrian research institute AEE INTEC, assumes worldwide employment figures in solar thermal to add up to no more than 460,000 full-time jobs in 2014 (find both studies attached).

Germany: Solar + Heat Pump + Ice Storage Achieves Seasonal Performance Factor of 5.6

Submitted by Baerbel Epp on June 22, 2015
Ice storage ConsalarGerman company Consolar offers a heating system called SOLAERA, which combines a heat pump with a specially designed solar collector and a heat storage space using the latent heat released when water freezes to ice (see photo). The solar heat pump system with 18 m² of collector area, a 300 litre ice storage space and a 1,000 litre buffer tank provides enough energy to heat a well-insulated building in Germany. In a field test by a local environment group, Lokale Agenda 21, it achieved a Seasonal Performance Factor (SPF) of 5.6, putting performance even above prior simulations. The SPF describes the ratio of delivered heat to electricity consumed over the entire year. Consolar sold about 160 solar heat pump systems in total, mostly in Germany but also in Denmark, the UK, Switzerland, Belgium, France and Italy. The systems there achieved SPFs between 3.5 and 6, depending on collector field size, maximum flow temperature and heat demand.

Submitted by Baerbel Epp on June 17, 2015
Conto TermicoThe administrator of Italy’s national subsidy scheme Conto Termico, Gestore dei Servizi Energetici (GSE), counted 9,658 applications over the first 18 months, among them 7,720 which reached the contract phase before the end of 2014. According to a recent GSE study called Performance Report on Conto Termico, solar water heating systems have been the technology of choice for 71 % of the approved applications, followed by biomass boilers with 24.5 %, although the gap between solar thermal and biomass stands wider in the southern regions of Italy (see attached document in Italian). The majority of subsidised solar water heaters have a size below 5 m² of collector area, as can be seen on the chart to the right, which shows all 5,443 approved solar applications. There are only 5 systems above 50 m² among the approved applications.

IEA SHC: Market Report Aggregates 56 Country Statistics

Submitted by Baerbel Epp on June 16, 2015
Solar Heat WorldwideIt is the most comprehensive publication on the global solar water heating market: the annual study Solar Heat Worldwide. On behalf of the IEA Solar Heating and Cooling Programme (SHC), Austrian research institute AEE INTEC has gathered data on 2013 market development from 56 countries worldwide – covering 95 % of the world market. The institute has asked national stakeholders for newly installed capacity, type of technology and application. Accumulating such detailed information at global level gives a comprehensive overview of the world market for solar heating and cooling. According to an extrapolation of the missing 5 %, installers set up a total capacity of 55 GWth – or 78.6 million m2 of glazed and unglazed solar collectors – in these 56 countries. The pie charts show the growing importance of large domestic hot water applications in multi-family buildings as well as the tourism and public sector (see page 36/37 of the attached study). In 2013, 17 % of the newly installed collector capacity was installed in this segment (right), whereas it only accounts for 9 % of the total installed collector capacity in operation (left). The number of unglazed solar collectors for private swimming pools has diminished worldwide. Although they still make up 6 % of the total capacity, they only contributed 3 % to the new collector capacity in 2013. With 577 MWth (0.8 million m2) of newly installed capacity in 2013, non-residential applications, such as district heating, process heat and cooling, are still a real niche market.
