A link to the event’s summary, agenda and documents is available here. The presentation was made by Tassos Frantzis, owner of Vesta Solar Heaters Ltd., a manufacturing company of solar thermal systems and member of ΕΒΗΕΚ (Cyprus Union Of Solar Energy Industrialists).

REN 21: Solar Thermal Contributes Significantly to Hot Water Production

Submitted by Baerbel Epp on June 30, 2014
top ten 2012According to REN21’s Renewables 2014 Global Status Report, which was published at the UN-hosted Sustainable Energy for All Forum in New York at the beginning of June, solar thermal technologies contribute significantly to hot water production in many countries and increasingly to space heating and cooling, as well as industrial processes. REN21 is a global multi-stakeholder network for renewable energy policy, connecting key actors from governments, international organisations, industry associations, science and academia, as well as civil society. First released in 2005, the report provides a comprehensive and timely overview of renewable energy markets, industries, investments and policy developments worldwide. The renewable energy data is provided by an international network of more than 500 contributors, researchers and authors. According to report data, the world added 55.4 GWth (more than 79 million m2) of solar heat capacity in 2012, increasing the cumulative installed capacity of all collector types in operation by over 14 % for a year-end total of 283.4 GWth. The chart above shows the shares in global capacity in operation across 2012’s top ten countries.

Greece: Sole’s Pool Heating Combines Geothermal Heat Pump and Solar Collectors

Submitted by Baerbel Epp on February 5, 2014
The new swimming pool complex in the sports centre of the Amaliada municipality in the Greek province of Ilia is heated by a combination of solar thermal collectors, three warm wells and an electric heat pump. An oil boiler serves as the backup system. Greek solar collector manufacturer Sole, which supplied the solar thermal system and was also responsible for planning it, says it is Greece’s only hybrid pool heating system combining a significant share of solar thermal and geothermal energy. The system cost around EUR 600,000 (including planning and installation) and was financed entirely by Greece’s Green Fund. The municipality is the beneficiary of the fuel savings.

USA: California Solar Initiative to Add Technologies to Eligibility List

Submitted by Baerbel Epp on June 13, 2013

The California Solar Initiative (CSI) is further extending the number of system types eligible for its CSI – Solar Thermal programme. Already in December 2012, California’s Governor, Edmund Brown, signed a law stipulating that solar heating of commercial pools is to be incorporated into the subsidy scheme. In March 2013, the California Public Utilities Commission (CPUC) published the Final Decision, specifying that solar cooling, space heating and process heat systems should be eligible technologies within the CSI – Solar Thermal. The CPUC, however, still has to work out the specific rule set, something which might delay implementation. The pie chart shows the share of system suppliers within CSI by the end of May 2013. By then, the programme’s administrators had received 1,400 grant applications, half of which had included the system supplier’s name.

Solar Water Heating Systems: A Review of Global Experiences (2010)

Submitted by Raquel Ponte Costa on May 29, 2012

Prepared jointly by India’s Ministry of New and Renewable Energy (MNRE) and the Renewable Energy and Energy Efficiency Partnership (REEEP), this report gives an overview of the Solar Water Heating Systems (SWHS) market in India over the last decade, and counterpoints it against broader global developments. After looking at global trends in market development, the document gives summaries of UNDP-GEF and REEEP experiences of SWHS projects. This includes summaries of specific projects over the last five years.

Solar Heat Worldwide. Markets and Contribution to the Energy Supply (2011)

Submitted by Raquel Ponte Costa on November 25, 2011

This report was prepared within the framework of the Solar Heating and Cooling Programme (SHC) of the International Energy Agency (IEA) as an update of the one issued in 2009. The report documents the solar thermal capacity installed in the important markets worldwide and its contribution in terms of supply of energy and CO2 emissions reduction. Documented collectors comprise unglazed collectors, glazed flat-plate and evacuated tube collectors with water as the energy carrier, as well as glazed and unglazed air collectors.

Integrated Unglazed Solar Panel Development (2010)

Submitted by Raquel Ponte Costa on November 24, 2011

This is a presentation of the research done by the Environmental Energy Solutions Ltd. for the development and testing of their prototype solar heat system. The particularities consisted in the large, low cost solar collector integrated into the roof or wall cladding system and its integrated water sourced heat pump and thermal storage system. A prototype was installed on a house in Wellington, providing year-round performance data. This report was done with the support of the New Zealand Energy Efficiency and Conservation Authority.

Technical Specifications for Solar Energy Installations (2010)

Submitted by Raquel Ponte Costa on November 18, 2011

The Decree No. 314/010 was issued by the Uruguayan authorities with the purpose of outlining the minimal technical conditions to be met by solar thermal installations. It regulates the use of these technologies, also serving as a guideline for all users, with a main focus on durability, reliability and security requirements.

Trainenergy Project. Module 9. Renewable Energy Systems (2011)

Submitted by Raquel Ponte Costa on October 21, 2011

The Trainenergy project ran from September 2009 to September 2011, with the objective to produce a training programme about the EU Energy Performance of Building and the Energy End-Use Efficiency and Energy Services Directives for tradesmen in the construction industry. The project was run in Ireland, UK, France, Germany, Spain and Denmark. This module presents the best renewable sources that offer heating at virtually zero carbon emissions, solar water heating being the first technology to be assessed.

Evaluating the Potential of Solar Thermal and Photovoltaic Energy in Compliance with the Technical Building Code (2011)

Submitted by Raquel Ponte Costa on October 18, 2011

The study published by the Spanish Institute for Energy Diversification and Saving (IDAE) presents an in-depth analysis of the solar thermal energy potential for domestic hot water and swimming pool water heating, as well as the benefits of the solar photovoltaic energy feeding into the grid. A key reference for the study has been the text of the Spanish Technical Building Code (CTE) in force.
