Since 2009, 1,234 million m² of collector area had been installed in Bengaluru and had supplied energy equivalent to about 611 million kWh of electricity required for showering each year, BESCOM has said when asked about the success of the project. The massive increase in the number of solar water heaters has been one of the most important measures to combat the city’s chronic power shortage.

Europe’s first-ever renewable heating and cooling target

Submitted by Baerbel Epp on June 26, 2018
Renewable Energy Directive for 2030After night-long negotiations, the European Parliament and Council have reached an agreement on the Renewable Energy Directive for 2030. At long last, discussions that started in November 2016 came to a close in the early morning of 14 June. The new regulatory framework stipulates that a 32 % renewable energy target is to be achieved by the EU in 2030. “This is a substantial increase compared to the 27 % originally proposed by the European Commission,” said Pedro Dias, Secretary General of Solar Heat Europe/ESTIF. “Moreover, the Commission can now take corrective action if this overall target is not met.”

SHC Solar Award: Five Finalists with Successful Support Policies

Submitted by Baerbel Epp on October 15, 2017
Administrators of successful solar thermal support schemes are in the focus of this year’s Solar Award of the IEA Solar Heating and Cooling Programme (IEA SHC). The jury has chosen five finalists, of which one will receive the SHC Solar Award during the IEA SHC’s joint conference with ISES Solar World Congress (SWC 2017) in Abu Dhabi on 1 November 2017. The finalists come from Australia, Austria, Germany, Lebanon and Tunisia (see logos above). They implemented very different support policies, such as rebates and/or loans as well as building obligations. Their activities all had a strong impact on their national or regional solar heating and cooling market.

California: San Francisco Passes First Mandate with Solar Thermal Option

Submitted by Baerbel Epp on July 14, 2016
LuminaltAfter Lancaster, Sebastopol and Santa Monica, San Francisco is now the fourth – and the largest – US American city to mandate the use of solar energy in residential and commercial newbuilds. It also has the first mandate in California which can be complied with by using either solar thermal or photovoltaics. The other three cities stipulated the installation of a PV generator at newly developed premises. The mandate in San Francisco aims at owners of new residential and non-residential buildings who apply for a building permit on or after 1 January 2017. The photo shows the typical multi-storey building structure and density of San Francisco.

Israel: Winter Hail Storm Boosts Replacement Rate

Submitted by Baerbel Epp on May 31, 2016
ElsolLast year, the Israeli market saw a significant increase in newly installed glazed collector area, showing a total of 428,750 m² or a 9 % increase compared to the previous year. Eli Shilton, Managing Director of Israeli solar thermal system supplier Elsol, believes that a hail storm last winter was responsible for the greater demand for system replacement. “Since local collectors have standard glass covers, the hail storm broke a lot of the glass,” Shilton explained and added: “People are not worried about it, as the systems were covered by insurance and most owners will be reimbursed for all of the damage caused.” Thirty years of experience have made Eli Shilton a well-recognised expert in the Israeli solar thermal industry. The photos show centralised solar thermal systems on new multi-family buildings in Israel.

Lesotho, Mozambique and Zimbabwe: Solar Thermal Policies under Development

Submitted by Baerbel Epp on March 10, 2016
University ZimbabweA growing number of countries in Southern Africa follow the example of South Africa and Namibia to set targets and discuss regulations for an increased deployment of solar water heaters. The reasons are the acute power shortages and the fact that residential households spend 60 % of their electricity on hot water preparation when they use an electric geyser. Lesotho and Zimbabwe launched national strategies in September 2015 to ban electric geysers and Mozambique’s Minister of Science, Technology, Higher Education and Professional Training, Professor Jorge Olívio Nhambiu, confirmed the target of installing 0.1 m² collector area per capita by 2030, as had been defined in the Solar Thermal Technology Roadmap for Zimbabwe in November 2015. The photo shows the Solar Energy Mobile Training Unit showcased during an open day at the University of Zimbabwe.

Brazil: Impact of São Paulo Solar Obligation

Submitted by Baerbel Epp on November 13, 2015
Velp Mais BrazilSão Paulo’s around 30,000 new building permits per year and a municipality bylaw (Number 14449/2007) which has required construction companies to make solar water heating part of almost every newbuild since 2008 have created expectations for a flourishing solar thermal sector in this Brazilian city. Independent consultancies estimate that the local solar obligation has led to 110,000 m² of collector area installed at residential buildings.

Uruguay: The Battle for Market Growth Continues

Submitted by Baerbel Epp on September 23, 2015
Uruguay market developmentUruguay, whose population of 3.4 million makes it one of the smallest countries in Latin America, has shown positive market development since 2007. Cumulated installed solar thermal power saw a notable increase from 1 to 9.5 kWth per 1,000 inhabitants. According to numbers published by the National Energy Department and the annual national energy report, the country’s total collector area installed by the end of 2014 amounted to 46,241 m². Mesa Solar, the multi-sector network for the promotion of solar energy in Uruguay calls for accelerated growth to achieve 1 million m² in 2020. The official target of the government is 150,000 m² until 2024.

Italy: 903 Municipalities with Solar Thermal Building Obligation

Submitted by Baerbel Epp on September 2, 2015
Italien MapIn Italy, a recent national decree no. 164/2014, the so-called Sblocca Italia, aiming at simplifying bureaucratic processes, introduced the concept of a standard building code, which should be developed by the government in cooperation with the regions and municipalities. Of course, in such a standard code, the provisions on energy efficiency and renewables will play a relevant role, which will once again ignite the debate on this hot issue. Hence, Legambiente, one of the major environmental associations in Italy, titled its annual study about the status quo of the implementation of the national renewable building code Simplification and Innovation in Construction: Towards the Building Regulations Act. According to this study, which was presented in February this year, 903 Italian municipalities introduced a mandatory regulation to cover a share of sanitary hot water demand, usually 50 %, with solar thermal technology (see the attached document). The map shows the regions with these kinds of mandatory regulations in place (red and green), as well as the regions without renewable building obligations (orange and yellow). Sicily introduced no specific building regulation.
