The Solar Thermal Federation of India (STFI) and the Indo-German Chamber of Commerce (IGCC) have teamed up for the international Solar Payback project, which aims to increase the use of solar thermal energy in industrial processes. The photo shows the partners during the Kick-Off Meeting in Mumbai, India, on 16 December 2016. Supported by the German Federal Environment Ministry funded by the International Climate Initiative, the three-year project will be implemented in India, South Africa, Mexico and Brazil. It is coordinated by the German Solar Association BSW-Solar and eleven partner organisations: three German companies, plus each target country’s national solar industry association and German chamber of commerce.
The recent approval of Working Rules means that the Global Solar Certification Network (GSCN) can now accept membership applications. The reuse of test and inspection reports in different certification schemes will be possible at the beginning of 2017. The GSCN was developed in Task 43 of the IEA Solar Heating and Cooling Programme to facilitate the cross-border trade of high-quality solar thermal products. The world map shows all the certification schemes which are already on their way into the GSCN – and more are said to follow soon. GSCN industry members can use a collector test report or a production inspection report from one of these schemes to apply for a certificate in another part of the world which is also part of GSCN. The procedure saves manufacturers time and money by removing the need for collector retesting or a second site inspection.
From 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.
System cost reduction is one of the most urgent challenges of the solar thermal sector, especially in central Europe. The aim of Task 54 of the IEA Solar Heating and Cooling Programme, Price Reduction of Solar Thermal Systems, is to lower solar heat prices by up to 40 %. Germany’s main scientific contributions to the task have come from the two research projects KoST and TEWIsol, which have been co-funded by the German Federal Ministry for Economic Affairs and Energy. The corresponding Task 54 meeting will take place in Stuttgart on 6/7 October (see the attached programme) in conjunction with a workshop on 5 October to present and discuss KoST and TEWIsol (12 p.m. to 4 p.m.; held in German). The photo shows the Task 54 workshop organised in collaboration with the European Solar Thermal Industry Federation in Brussels in May 2016.
Usually, the period between September and December is a popular time for holding conferences and fairs. This year is no different. Below, you will find a number of international events dedicated to solar heating and cooling in different corners of the globe. You can also go to the calendar of events for a more comprehensive list of what’s happening during the second half of 2016. Photo: Stephanie Banse
The SoPro India project has scientifically monitored two solar water heating systems for a year with the aim of presenting reliable data on system performance (see the attached PDFs). The measured 20 % solar efficiency would put the ROI between 2 and 3 years, depending on the development of fossil fuel costs. The researchers from German institute Fraunhofer ISE see new systems offering “good opportunities for further technical improvement.” SoPro was implemented by the German Agency for International Cooperation (GIZ) in cooperation with the Indian Ministry of New and Renewable Energy (MNRE).
Solar heating and cooling has not been bankable yet despite various systems confirming expected performance and O&M costs. Project budgets are usually too small and the technology suppliers do not pass the stringent requirements of creditworthiness, which leaves the financial provider with a high-risk scenario. Accordingly, Energy Service Companies (ESCOs) have faced severe financing issues, which slow down the expansion of their business. It is good news to them that two recently launched projects also focus on facilitating the creation of an investment fund for solar thermal ESCO projects: First, there is the Feasibility Study - Energy Contracting Fund, which is jointly coordinated by the German Investment and Development Corporation Bank (DEG) and German SHC turnkey provider Industrial Solar; the second project, TrustEE – enhancing investment conditions for industrial energy efficiency and renewable energy projects, is from the EU and has been coordinatedby Austrian institute AEE INTEC.
How much will the transformation of the German energy industry cost if it is to reach greenhouse gas emissions reductions of at least 80 % by 2050? The German Institute Fraunhofer ISE used its Renewable Energy Model REMod-D for Germany 2050 to perform the simulations necessary to answer this key question. REMod-D considers all kinds of energy end-use applications (in manufacturing, transport and residential segments) and each and every energy technology. Simulations are performed on an hourly basis to ensure the security of supply in all industries throughout the year. The studied scenarios differ with regard to drive concepts used in the private and commercial transport industry, the extent of energy retrofits in the building industry and the exact time at which coal will no longer be used to generate electricity. The most recent REMod-D study, which was published in November 2015, was called “What Will the Energy Transformation Cost? Pathways for Transforming the German Energy System by 2050” (see attached document in German). Solarthermalworld.org spoke with Sebastian Herkel from Fraunhofer ISE about the study’s solar thermal outcomes and the use of REMod-D in urban planning scenarios of Task 52 of the IEA Solar Heating and Cooling Programme.
The main objective of IEA SHC Task 52, Solar Thermal in Energy Supply Systems in Urban Environments, is to call attention to both the technical and economic aspects of solar heating and cooling usage in densely populated urban areas. Urban planners and commercial clients want to know the costs compared to the energy output generated by various solar heating technologies. A method to benchmark different solar heat production systems is Levelised Cost of Energy (LCOE). This method is described by the IEA as the “average price that would have to be paid by consumers to repay exactly the investor/operator for the capital, operation and maintenance and fuel expenses, with a rate of return equal to the discount rate”. The chart shows the LCOE for different applications and system sizes in northern / central European climates, taken from the most current Task 52 study Technology and Demonstrators (for further details see table below). The author of the study, Franz Mauthner from Austrian research institute AEE INTEC, contributed to this article, which elaborates on the method and the calculations behind it.

Almost 30 experts from 25 partner organisations met in Bolzano, Italy, on 21 and 22 March for the kick-off meeting of IEA SHC Task 56, Building Integrated Solar Envelope Systems for HVAC and Lighting. The overall goal of the task is to find out “why some ways of solar integration do work, while others don’t,” as the Task Operating Agent and Coordinator of the Sustainable Heating and Cooling Systems research team at Italian institute EURAC, Roberto Fedrizzi, put it – and, of course, to find measures to improve solar technology integration into façades and roofs. The photo shows a residential home in Stavern, southern Norway, where 7 m2 of solar collectors have been integrated into window frames in the south-facing facade, contributing to both domestic hot water preparation and space heating.
