IEA SHC Task 46: Bankable Solar Data Sets for Concentrating Technologies

Submitted by Baerbel Epp on November 2, 2016
Whether investors put their money into large-scale concentrating solar heat and power systems, solar district heating plants or photovoltaic fields, they need to be able to rely on data sets to include the uncertainty and variability of input information. Financial institutions do like to know in what way these factors can impact revenue flows in financing, so researchers of IEA SHC Task 46, Solar Resource Assessment and Forecasting, have spent several years analysing various approaches to the topic. The flow chart of the financing model shows that solar resource data is essential to a proper assessment of the average power or heat generation per year as well as the range of variability over several years. SHC Task 46 is a five-year collaborative effort (2011-2016) with support from the IEA SolarPaces Programme (Task V) and the IEA Photovoltaic Power Systems Programme (Task 14).

Romania: Hike in Green House Programme Applications

Submitted by Baerbel Epp on October 30, 2016
Casa VerdeThe relaunched Green House Programme (Casa Verde) has been a very popular national residential subsidy scheme across Romania. According to the Environmental Fund Administration (EFA), as many as 3,748 homeowners submitted an application on 10 October 2016, the starting day of the new two-week submission period ending on 24 October. The Green House programme subsidises solar thermal systems as well as heat pumps. 
 

India: Vacuum Tube System with PCM Storage Tank Heats Troop Shelter

Submitted by Baerbel Epp on October 28, 2016
DIHARThe Indian Defence Institute of High Altitude Research (DIHAR), a laboratory of the Defence Research Development Organisation, has successfully tested a vacuum tube collector system for space heating at extreme altitudes. The testing site, a troop shelter, was set up last year in the region of Ladakh in the northern Indian state of Jammu and Kashmir at the Chang La, a high mountain pass at 5,360 metres above sea level, and the tests were conducted there over the winter. The system stores solar heat harnessed during the day in a phase-change storage tank and uses it to keep the 90 m² shelter warm at night. During the test run, the inside of the shelter showed between 7 and 10 °C while the temperature outside was minus 30 °C.

Spain: EuroSun 2016 Focuses on Complete Solar Systems

Submitted by Baerbel Epp on October 27, 2016
Wolfgang Streicher; Eicke Weber; Victor Martinez MollFrom 11 to 14 October, more than 300 experts in solar energy met in Palma de Mallorca for the EuroSun 2016 conference. Organised by the International Solar Energy Society (ISES) in cooperation with the University of the Balearic Islands (UIB), the conference is attended mainly by scientists and industry stakeholders from the solar heating and cooling sector. But for the first time, speakers also included well-known specialists from the photovoltaics sector. Two panel discussions illustrated the wide range of opinions on solar heat and solar electricity market development and the technologies' competitors. The photo shows Professor Eicke Weber (middle), newly elected Vice President of ISES and Director of the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) based in Freiburg, Germany, and two of the three conference chairs: Professor Wolfgang Streicher (left) from the University of Innsbruck, Austria, and Professor Víctor Martínez Moll (right) from the UIB.

France: Is This The New Solar District Heating Country?

Submitted by Baerbel Epp on October 26, 2016
France District Heating ResultsAfter France had become involved in a couple of EU-supported projects as a newcomer, the country is now ready for take-off in the solar district heating (SDH) market. Monitoring data from the first two French pilot plants show performance to be quite good and the systems to be highly reliable. The chart depicting the performance of the 458 m2 evacuated tube collector field in Balma-Gramont was presented by Fabrice Renaud, Research Engineer in the R&D centre Cylergie at the French group Engie, during the 4th International Solar District Heating Conference in Billund, Denmark. There is also a new strategy document being devised to advance the development of SDH in the French region of Auvergne – Rhône-Alpes.

Argentina: President’s System Order and Planned Energy Price Hikes Boost Solar Thermal

Submitted by Baerbel Epp on October 24, 2016
Argentina EnergeAfter having announced plans to sharply increase energy prices across the country, the Argentine government is said to approve new legislation for promoting solar thermal technology. A new bill, which is expected to be passed by the end of 2016, is thought to create a number of financial incentives, soft loans and a binding obligation for solar water heaters in public buildings. However, the domestic market has already been experiencing remarkable growth: Solar water heaters have gained a significant boost in popularity since this July, when President Mauricio Marci ordered a 260-litre system equipped with a flat plate collector from Energe, one of Argentina’s major solar thermal suppliers. The photo posted on Energe's Facebook page shows the president (middle) and a team from the company at the new solar thermal installation.

Bulgaria: Third Phase of Residential Energy Efficiency Credit Line Launched

Submitted by Baerbel Epp on October 20, 2016
Bulgaria multi-family blocksAlthough Bulgaria is a country with many green or mountainous areas, it has had to grapple with severe air pollution caused not only by old cars, but also by wood-fuelled heating systems, which are popular across the country. The European Environment Agency has recently rated the Bulgarian capital, Sofia, as the most polluted one in Europe. Last year, the conservative government of Prime Minister Boyko Borissov stepped up to the plate and announced the National Programme for Energy Efficiency of Multi-Family Residential Buildings (NPEE). Its aim is to provide billions of euros for making several thousand residential buildings energy efficient until the end of 2018 – with no charges to flat owners. The photo shows three blocks of flats awaiting modernisation.

IEA SHC Task 51: German Summer School Educates Students on Solar Urban Planning

Submitted by Baerbel Epp on October 18, 2016
Summer School BerlinThe summer school called City in Transition (Stadt im Wandel) ended with a public presentation of the project designs from four student groups on Monday, 26 September, in Berlin, Germany (see photo). During the previous week, students from different fields and German universities had developed a master plan for solar-optimised buildings in an area of Berlin’s Adlershof district. ”We educated students on how to combine town planning and solar energy usage,” explained Tanja Siems, one of the organisers of the summer school and Head of the Institute of Urban Design & Studies, Faculty of Architecture and Civil Engineering of the University of Wuppertal, Germany. Several experts from the IEA Solar Heating and Cooling programme’s Task 51, Solar Energy in Urban Planning, had supported the summer school as tutors or evaluated the final presentations.

Denmark/Sweden: Arcon-Sunmark Collector Retesting Prompts Discussion on Solar Keymark Network Rules

Submitted by Baerbel Epp on October 16, 2016
This July, SP issued new Solar Keymark certificates for four Danish Arcon-Sunmark collectors after the Swedish test lab and certification body had retested these four systems in April. The retesting had been necessary, as SP had received six complaints because of a lower-than-expected c1 (heat loss coefficient) value on certificates issued in November 2015. At first, it looked like a case closed, but the stakeholders who submitted complaints are now calling for a reform of the complaint procedures and tolerances established by the Solar Keymark Network (SKN). 
 

Nicaragua: Soft Loan to Fund EUR 4 Million Project

Submitted by Baerbel Epp on October 14, 2016
Hospital ManaguaThere is now nothing in the way of constructing an impressive solar heating and cooling installation in Nicaragua. At the end of September, the last signatures were placed under the contract documents for a 4,450 m² collector field which will supply air conditioning and warm water to the Hospital Militar Escuela Dr. Alejandro Dávila Bolaños in Managua (see photo), the capital city of the central American nation. “Installation work will start in January 2017, and commissioning is planned for the second quarter of next year,” was how Christian Holter, Managing Director of S.O.L.I.D, outlined the ambitious plan. The Austrian turnkey system supplier had been struggling for over three years to receive financing for the 4 million EUR project in form of a soft loan, a financing instrument for developing countries.
