This report provides an overview of the state of the art of measuring heat delivery in larger solar systems, looking also at the costs and accuracy of the measuring systems. The present document was produced within the framework of the Intelligent Energy- Europe project Key Issues for Renewable Heat in Europe (K4RES-H. The project looks at providing guidelines for best practice policies to support renewable heating and cooling (RES-H) technologies.
This document from 2007, released by the European Commission, refers projects, financed under the 6th EU Research Framework Programme (FP6), to boost the use of solar power technologies in Europe, as a part of the EU’s goal of achieving 20% share of renewable energies inits overall energy consumption by 2020 and a minimum 10% share of biofuels in overall EU transport petrol and diesel consumption by 2020. Concentrating Solar Power (CSP) is a clean energy that can help the EU to meet this 20% goal.
FSEC Solar Thermal Manual
Design and Installation & Repair and Maintenance
The intent of this manual is to equip the reader with the knowledge and skills needed to design, install, operate and maintain the most common types of solar water heating systems.
Solar Power is where business takes place! If you have a professional interest in solar energy (photovoltaics, concentrating photovoltaics, solar thermal electric or solar hot water), this event has something to offer your business.
Intersolar is the world´s largest solar technology trade fair and the annual meeting place for everyone in the international solar Industry. Intersolar focuses on the Photovoltaic, Solar Thermal and Solar Architecture branches. More than 1,000 exhibitors will be presenting their products and services across 76,000 m² of exhibitor floor space – an increase of more than 120% from 2007. This year, Intersolar expects more than 40,000 visitors.
So far solar thermal technology is mostly used for domestic hot water, pool heating and room heating. It´s often forgotten that there is a huge demand for heat below 250 °C in industry, which can easily be reached with solar thermal collectors.
An international team of researchers working on behalf of the International Energy Agency estimated the realisable potential of solar process heat in the European Union at 100 GWth, which corresponds to 140 million m2 of collector area. T
Today, however, a solar thermal capacity of only 13.5 GWth is in operation across Europe. Task 33 of the International Energy Agency reported 85 solar process heat plants worldwide with a capacity of 27 MWth. However, this market segment seems to be waking up. Just recently, news about huge solar process heat installations did the rounds. There is the 13,000 m2 plant in Hangzhou, China, on the roof of the textile dyeing factory Daly Ltd., which is most probably the biggest installation for solar process heat in the world. The total investment adds up to RMB 12 million (€ 1.11 million) including the tanks and mounting system. According to the project developer, the Chinese company Shenzhen Quir Solar Technology Co., Ltd, the solar collectors will save RMB 3.38 million (€ 0.31 million) per year, so that the investment will pay off within 3 years. The hot water is provided at a low temperature of 55 °C. Secondly, this summer the German brewery Hofmühl GmbH in Eichstätt will start operating a pilot plant with 1,389 m2 of vacuum tube collectors, which will supply process heat between 90 and 140 °C to the brewing and cleaning processes. The owner of the system estimates a reduction of 20 % in the annual energy demand of the factory. The company is convinced that the investment will pay off and has plans for subsequent upsizing to 3,000 m2. The project is being subsidised by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety.

Established as an inter-disciplinary cooperation exchange, the Solarpraxis Forum will again this year bring the players from the solar industry in contact with representatives from the political and financial worlds and with the press.
The Solarpraxis Forum offers up to date and practical lectures on all non-technical issues. The emphasis in the presentations is always on the practical applicability of the information and real project experiences.
Intersolar North America, held in conjunction with SEMICON West, will be the largest trade event in the United States serving the complete solar energy supply chain. It will provide a unique insight into what the American and international solar markets have to offer. The event will utilize 350,000 square feet of combined exhibition space throughout the Moscone Center and will draw around 200 international solar-related companies and 1,400 exhibitors overall. Over 10,000 visitors are expected to attend Intersolar North America.
2006 was an extremely satisfying year for the global solar thermal industry. According to the new study “Solar Heat Worldwide. Markets and contribution to the Energy Supply 2006” on behalf of IEA Solar Heating & Cooling Programme the new installations grew 22 % in 2006. The authors from the Austrian research institute AEE Intec surveyed 48 countries and added up the newly installed collector area to 18.3 GWth (26.1 million m2).

Conferencia de la Industria Solar - Espana 2008 (CIS-ES 2008) aims to become the main platform for debate and for the exchange of information and knowledge across the solar energy and related fields. It aims to bring the members of the sector into contact with political representatives, the financial world and the media. The conference will provide a framework allowing contact between people interested and involved in renewable energy issues.
The success of the 2nd conference on solar air conditioning held in Tarragona in October 2007 represented a clear message to scientists, professionals, firms, and organizers: The positive trend of solar cooling applications is growing stronger. A number of technical seminars, courses, and communication actions have been organised in several countries. Congresses, exhibitions, and fairs have been recently included into the Solar Cooling topics beside the traditional ones.
Conferenza dell’Industria Solare – Italia 2009 (CIS-IT 2009) will take place for the first time in Italy in 2009. This event follows on from the well established German Forum Solarpraxis, which has been held annually in Berlin since 1998, and the successful CIS-ES in Spain, which was launched in 2007 and will take place again this October in Madrid. Politics, Market & Finances, Marketing & Sales and Public Relations are the main topics of the two days conference.
Renewable Energy India 2008 Expo is the melting pot for global technologies. It is a platform to provide value for the domestic industry and showcase opportunities in the Indian market for global players. It is a forum to nurture business contacts, imbibe the latest technology trends, cultivate business relations and prepare for the exponential growth of renewables in India.
RE2008 is an international conference and exhibition for the advancement of renewable energy technology and industry. The event was successfully started in Tokyo, Japan, in 2006 (RE2006) and was decided to continue at every two years.
The Tunisian solar thermal market has increased tenfold in only the last four years. Before starting the grant programme Prosol II in 2005, only 7,000 m2 had been installed in Tunisia (4.9 MWth). Last year already showed installations of 60,000 m2 (42 MWth), 74 % more than in the previous year. For 2008, the official target is 80,000 m2 (56 MWth) of newly installed collector area.
Germany's solar thermal market is growing again, and this at an astonishing rate. After market sales plummeted by 37 % in the past year, the monthly sales statistics of BDH (Federal Industrial Association Germany House, Energy and Environmental Technology) – as they are available to the author – show encouraging increases in all segments. In the first half of this year, the quantity of flat-plate collectors rose by 85 % to 779,507 m2 (546 MWth), compared to the previous year. Evacuated tubes showed an increase of 55 % to 88,416 m2 (62 MWth).
After almost 20 years of stagnant markets, since 2005 the U.S. solar thermal market is exploding. According to the official governmental statistics (www.eia.doe.gov) the market rose by 77 % in 2006 to 111,480 m2 (78 MWth). After many years of winter sleep the local industry is waking up. Interesting and self-confident newcomers enter the stage.
