Associations Kick off European Solar Thermal Energy Standardisation & Certification Working Group

Submitted by Baerbel Epp on December 4, 2013

Four major solar and heating associations in Europe jointly kicked off the ESTESC working group in Berlin at the end of November. ESTESC stands for European Solar Thermal Energy Standardisation & Certification. The four associations are the two Brussels-based associations European Solar Thermal Industry Federation (ESTIF) and the Association of the European Heating Industry (EHI), as well as German associations BSW Solar and the Federal Industrial Association of Germany - House, Energy and Environmental Technology, BDH. All members of the four organisations have been invited to become active participants of a number of subgroups within the ESTECS working group. Christian Stadler, Technical Head at Austrian company General Solar Systems, was elected Chair of the ESTESC for the next three years. He started his career in the solar thermal industry in 1991 and worked in leading positions at 4 different collector manufacturers. Since 2008, he has been responsible for product management, development and strategic sourcing at General Solar Systems with its major brand Sonnenkraft.

India: New Five-Year Guarantee on Solar Tanks

Submitted by Baerbel Epp on December 2, 2013

Many Indian regions suffer from bad water quality: More than 75% of the country has moderately hard to very hard water. Chloride levels are also high in specific areas when water is obtained from boreholes. The “desired” legal chloride limit for drinking water is 0.25 g/litre, but is allowed to increase to 1 g /litre. As a result, solar thermal storage tanks gradually corrode and tend to develop leaks. Statistics obtained from the national Helpline show that over 70% of product-related complaints are about leakages in storage tanks. The photo shows a corroded extremely scaled hot water tank.

Mexico: Country Plans Compulsory Standard for Solar Thermal

Submitted by Baerbel Epp on November 28, 2013

In November, the last ISES Solar World Congress 2013 in Cancún, Mexico, offered a diverse range of topics. With regard to solar thermal energy in Mexico, the most outstanding piece of news was the announcement of a new standard planned by the National Commission for Energy Efficiency, CONUEE. The new standard will be based on the Official Mexican Norm NOM-ENER and could help revive the currently stagnant Mexican solar thermal market. Working out the details of the new standard is scheduled for early 2014.

COPANT: One Common Standard - Better than 31 Different Ones?

Submitted by Baerbel Epp on November 6, 2013

To date, solar thermal energy has been a largely unregulated technology in Latin America. Most of the countries in the region are suffering from nationalised, uncoordinated and sometimes insufficient quality standards. This lack of agreement is hindering the development of a shared and mature market. The regional Pan American Standards Commission, COPANT, is now working to address the issue by creating a unified regional standard and certification scheme for solar thermal components and systems. Although it is believed that a common standard and certification could ease current trade barriers, some market players think that, depending on the kind of regulation, it could create further obstacles to trade and technology exchange.

Global Collector Test Standard Incorporates New Technologies

Submitted by Baerbel Epp on October 24, 2013

The final version of the EN ISO 9806 was approved by the international standard committees CEN/TC 312 and ISO TC180 with more than 90 % of the votes shortly before their meetings in Freiburg, Germany, in the middle of September. This is an important milestone for the solar thermal industry, because it marks the first time that there will be a modern global standard for collector testing procedures which different countries can refer to. In addition, the new standard includes testing methodology for a number of new solar thermal technologies, such as solar air heating collectors, concentrating medium-temperature collectors and PVT collectors. Now, it will only be a matter of weeks until the standard is handed down to the national standardisation secretariats and, over the coming month, distributed through their national publication channels.

India: New Standards for Vacuum Tube Collectors and their Storage Tanks

Submitted by Baerbel Epp on September 16, 2013

The Indian Ministry of New and Renewable Energy (MNRE) has specified the standard requirements for evacuated solar collector tubes intended for non-concentrating solar collectors and related storage tanks.

Bulgaria: CL SENES – Hard Times for Well-established Solar Research Centre

Submitted by Baerbel Epp on August 6, 2013

Next to the Tsarigradsko Chaussee, an important road artery leading to the outskirts of Sofia, one can make out a vast research area belonging to the Bulgarian Academy of Sciences (BAS). On its campus, some scientists produce food for astronauts, others focus on solar energy (see photo). The Central Laboratory of Solar Energy and New Energy Sources (CL SENES) was founded in 1978 and played an important role in the energy efficiency programme of Todor Zhivkov´s government until the fall of communism in 1989. The lab’s research was focussed on using solar thermal energy to heat water in state-owned hotels and enterprises. Back then, some 50,000 m² of solar collectors were installed mainly along the Black Sea coast.

UK: Domestic RHI Tariff Applies to Installations After 15 July 2009

Submitted by Baerbel Epp on August 5, 2013

In July 2013 the UK’s Department of Energy & Climate Change (DECC) confirmed the tariff rates for the long-awaited Renewable Heat Incentive (RHI). The Government’s press release at 12 July 2013 promises that the solar thermal tariff will be set at ‘at least 19.2 Pound Stirling pence (p)/kWh’. This compares with 7.3 p/kWh for air source heat pumps, 12.2 p/kWh for biomass boilers and 18.8 p/kWh for ground source heat pumps.

Costa Rica: Small Market but Prestigious Large-Scale Projects

Submitted by Baerbel Epp on July 23, 2013

Costa Rica’s local solar thermal industry has been getting organised: The Solar Energy Association of Costa Rica, Acesolar, was officially founded last year. In early 2013, all formal issues were resolved and Acesolar was able to start working. Currently, the association has around twenty members. In February, a committee began developing a national standard for solar thermal systems. Cheap vacuum tubes from China are currently very popular. The photo shows one of the recent prestigious large-scale solar projects, which was finished in April 2013. The installation at the MultiSpa consists of 64 glazed flat plate collectors covering the hot water demand and 320 m² of unglazed collectors to heat the Olympic-size pool.

Uruguay: Growing at Its Own Pace

Submitted by Baerbel Epp on July 15, 2013

Uruguay’s government aims at reaching a renewable share of 50% in its national energy mix by 2015. In order to achieve this target, the government approved the so-called Solar Plan in March 2012. It offers up to USD 800 per solar thermal system to clients of the main public utility UTE. UTE reduces the energy bill of any SWH purchaser Uruguayan Peso (UYU) 700 over the first 24 months (UYU 16,800 = USD 800). In addition, the new Decreto No 451/011 mandates a 50 % solar share for hot water generation in hospitals, hotels and sports clubs – for both newly built and soon-to-be-renovated houses. However, some industry actors did not see a dramatic growth in solar thermal installations. Despite a lack of official statistics, one figure is clear: The subsidy scheme offers a budget for 2,000 systems, out of which 600 were already completed between March 2012 and July 2013.
