Solar Water Heating Techscop Market Readiness Report (2014)

Submitted by Raquel Ponte Costa on January 12, 2015

This report and methodology was developed in the framework of  the Global Solar Water Heating (GSWH) Market Transformation and Strengthening Initiative, which is the result of a joint collaboration between the European Solar Thermal Industry Federation (ESTIF), the International Copper Association (ICA) and the Global Environment Fund (GEF) of the United Nations Environment Programme (UNEP).

Bulgaria: New Solar Thermal Market Data Published

Submitted by Baerbel Epp on January 12, 2015
It is crucial for stakeholders – no matter in which markets they operate – to obtain accurate statistical data before making investment decisions. Sometimes, however, this is not an easy task; an example of how difficult it is to rely on published statistics is the Bulgarian market for solar thermal energy. The June 2014 market report (331 downloads | 7.26 MB) by the European Solar Thermal Industry Federation (ESTIF) showed the newly installed collector area in Bulgaria in 2013 to add up to 5,600 m². But the country’s leading flat plate collector manufacturer, NES New Energy Systems, located in the town of Shumen in northeast Bulgaria, reported an annual production volume of 20,000 m² for 2013 and sales of 12,000 m² during the same year. This means that the NES collectors alone (assuming that they were installed) would double the market volume which was published in the ESTIF report. In an attempt to find an explanation for the diverging figures, solarthermalworld.org contacted the available sources.
 

Jordan: “The solar bylaw is not going to have a strong impact on the market”

Submitted by Baerbel Epp on January 6, 2015
Millennium Solar EnergySince April 2013, Jordan has had a solar bylaw in place. The rules of the bylaw were stipulated in Article 10 of Law No. 73, which had already entered into force in 2012. Solar water heaters are a mandatory requirement for every new multi-family building with more than 150 m² of living space, for every new office building exceeding 100 m² of floor space, as well as each new public building with more than 250 m². There are, however, no additional regulations regarding quality standards or system sizes. Solarthermalworld.org spoke with Angelika Cerny, International Sales Coordinator at Jordan-based solar thermal turnkey-solution provider Millennium Energy Industries (MEI), about the effectiveness of the bylaw and the market development in Jordan. The photo shows an 80 m2 vacuum tube collector field which was set up in 2013 as a pergola for the office building of Jordan company EDGO Ventures in Amman.

Bylaw in Jordan

Submitted by Baerbel Epp on January 6, 2015
In 2012, the Ministry of Energy and Mineral Resources along with the National Energy Research Center in Jordan approved a solar bylaw which entered into force in April 2013 (see the attached document). According to Article 10 of Law No. 73, solar water heaters are a mandatory requirement for every new multi-family building with more than 150 m² of living space, for every new office building exceeding 100 m² of floor space, as well as each new public building with more than 250 m². The bylaw encourages spreading the national awareness in the field of conservation of energy and improvement of its efficiency and helps establishing a database related to conservation of energy and improvement of its efficiency. There are, however, no additional regulations regarding quality standards or system sizes.

Analysis of a Closed Loop Solar Energy System Using the -f Chart Method: Effect of Different Brazilian Locations (2013)

Submitted by Raquel Ponte Costa on January 6, 2015

This study, conducted by Alexandre M.S. Costa of the State University of Maringá and published by the State University of Ponta Grossa in Brazil, analyzes the annual energy performance of a closed-loop hot water solar thermal system under various weather conditions in 6 Brazilian cities (Curitiba, São Paulo, Rio de Janeiro, Recife, Salvador and Brasília) using the -f chart method. This method is based on 2 different approaches. It calculates the fraction (f) of monthly heat load that comes from solar energy.

Poland: From Renewable Heat to Renewable Electricity Funding

Submitted by Baerbel Epp on January 6, 2015
The Polish solar thermal industry is going through difficult times right now. At the end of December 2014, the National Fund for Environmental Protection and Water Management, NFOŚiGW, approved the last applications for the national residential incentive programme. The follow-up financial mechanism, Prosument, is a lot less attractive and has not really started yet for solar thermal. In contrast to the previous long-term subsidy scheme, which focused on solar heat, Prosument basically subsidises renewable sources of electricity. Solar thermal is only accepted in combination with an electric source, e.g., heat pump + PV or solar thermal collector + PV (for more information about Prosument, please see the database of incentive programmes. The programme was first introduced as a two-year interim programme, but has now been turned into a nine-year scheme running until 2022. Polish Zloty (PLN) 800 million (EZR 187 million) is available in funding, although they will not be allocated to the six eligible technologies.
 

China: First Chinese Solar Cooling Conference to Take Place in Shanghai in March

Submitted by Baerbel Epp on January 5, 2015
SHC ConferenceThis spring, a major event for solar cooling is going to take place in Shanghai: From 23 to 27 March 2015, the IEA Solar Heating and Cooling Programme and the Shanghai Jiao Tong University (SJTU) will jointly organise a Solar Cooling Week in the city. The week is going to start off with two Task meetings and end with the two-day Solar Cooling Conference (SCC). The SCC will take place for the very first time, be open to the public and include technical site visits on 26 March 2015, as well as a full-day conference with plenary and parallel sessions on 27 March 2015.
 

France: Third Solar District Heating Conference Call for Paper

Submitted by Baerbel Epp on January 3, 2015
BalmaAfter Denmark and Germany, it will now be France’s turn to host the Solar District Heating Conference. Researchers, as well as representatives from municipality utilities and solar thermal system suppliers will meet in Toulouse on 17 and 18 June 2015 to discuss international case studies, new business models and marketing strategies. The two-day event will consist of a mix of panel discussions, presentations by industry experts and site visits. In Toulouse, conference participants can visit the first French solar district heating plant, which is located in the eco-district of Balma and boasts 458 m² of vacuum tube collectors on a shade structure on top of a parking lot (see photo).

Solar Thermal Systems in Industry (2014)

Submitted by Raquel Ponte Costa on January 2, 2015

This presentation was given by Stéphane Joblot of E-Sol, a company specialized in renewable energy studies, during a workshop organized in the framework of the Energievie.info programme of the Alsace region, with the support of  ADEME, the French Environment Agency.  After giving a general overview of various solar thermal techonololgies and applications, the speaker shares the findings from a case study which analyzed the process needs of an agri-food company in the city of Colmar. This company operates 5 days a week and needs 4.000 liters of water at 60° C daily.
