Domestic Hot Water and Heating

Guide for potential investors

Submitted by Baerbel Epp on January 15, 2018
Solar Thermal NowAgainst the low standing of solar thermal technology, the British Solar Trade Association (STA) has launched a 16-page colourful brochure. The guide called Solar Thermal Now - A guide for domestic, business & public sector investors showcases the technology’s merits, the flexibility and broad application of solar thermal, while highlighting its enormous potential for cost and carbon savings. The report is available for download attached and association members can order hard copies. The brochure reveals some of the misconceptions in the support structure for ST in UK.
 

Delay in launch of Croatia’s residential support scheme

Submitted by Baerbel Epp on December 27, 2017
CroatiaCroatia, a western Balkan country, is one of the most sun-rich nations in the EU, but progress on the solar thermal front has been unsatisfactory in the eyes of Professor Ljubomir Majdandžić, Acting Director of the Environmental Protection and Energy Efficiency Fund (EPEEF). “Our energy development strategy envisions the installation of 0.25 m² of solar collector area per capita until 2020. But it has become clear that this target will not be met,” he said. 
 

Sun provides 70 % of hot water in blocks of flats

Submitted by Baerbel Epp on December 13, 2017
Construtora AlttiMore than 3,500 solar water heating systems have been in operation at blocks of flats across Brazil’s ‘solar city’ Belo Horizonte. This figure, an estimate by organisations which were previously part of a business cluster called BH Solar, affirms the city’s exceptional status in Brazil and around the world. Most of the solar systems have been installed on the roofs of high-rise buildings intended for the middle class and the wealthy. The photo shows two such structures. One flat has 4 bedrooms and extends over an entire floor, measuring 280 m². To provide the security that owners were looking for, recreational facilities, such as a swimming pool and a tennis court, have been set up inside the walls put up around the complex.

EU Funding for Solutions to Decarbonise Heating and Cooling Market

Submitted by Baerbel Epp on November 19, 2017
Horizon 2020A search for ‘solar thermal’ in a recently published 195-page document titled Secure, Clean and Efficient Energy will not return encouraging results (see the attached document). The publication by the Horizon 2020 Work Programme 2018-2020 shows only 6 entries in total. “Solar thermal is definitely not a priority of the new programme,” said Daniel Mugnier, Head of R&D at French engineering services company Tecsol. “And even if the European Solar Thermal Technology & Innovation Platform were to try to promote several hot topics, there’s only one call [LC-SC3-RES-7-2019 on solar process heat] dedicated to the technology.”
 

SHC 2017: Largest experts’ meeting on integrated solar heating and cooling

Submitted by Baerbel Epp on November 8, 2017
SHC2017_1500 experts from more than 50 countries attended the 5th International Conference on Solar Heating and Cooling (SHC) in Abu Dhabi, UAE, from 30 October to 2 November 2017. It was the first time that this biennial conference by the IEA’s Solar Heating and Cooling Programme had been organised jointly with the Solar World Congress by the International Solar Energy Society (ISES). The new partnership resulted in 2017’s largest experts’ meeting on integrated SHC solutions for buildings, industry, cities, regions and utilities, and in over 300 presentations.

Belo Horizonte – Brazil´s Solar Capital

Submitted by Baerbel Epp on October 25, 2017
Belo HorizonteBelo Horizonte, a municipality about 600 km north of Sao Paulo in the state of Minas Gerais, is also known as the solar capital of Brazil. Not only does it have a population of about 2.5 million, but solar water heater installations on many of its high-rise multifamily buildings. The photo shows one example, a block of flats for the wealthy middle class. The roof is completely covered in solar water heaters, which meet around half of the annual hot water requirements. This article will present the main drivers of an exciting market development in Latin America: a university research group specialised in solar heating and cooling, committed system planners, strong manufacturers and a pro-solar state utility.

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.

Switzerland: Strong Heat Pump and PV Competition

Submitted by Baerbel Epp on October 3, 2017
Switzerland market statisticsThere couldn’t be a starker contrast between the market development of two renewable heat segments: Whereas Swiss heat pump sales remained at around 18,400 units per year from 2014 to 2016, collector sales dropped significantly from 117,634 m² in 2014 to 66,699 m² last year. Market volume is now below where it was ten years ago and solar water heaters are facing strong competition from heat pumps and photovoltaics (see attached market report in German and French). The annual solar thermal symposium on 8 November in Dübendorf near Zurich will provide an opportunity to discuss alternative applications and technologies.

IEA SHC Task 52: Solar Thermal’s Role in 2050 Energy Mix

Submitted by Baerbel Epp on September 29, 2017
Collector Installation in HamburgWhat role solar thermal will play in the energy sector in 2050 is one of the principal questions that the international Task 52 research project Solar Heat and Energy Economics in Urban Environments intends to answer. As part of this IEA Solar Heating & Cooling Programme task, Denmark’s Aalborg University chose four major solar thermal countries in Europe – Austria, Denmark, Germany and Italy – to model their 2050 solar share in national heat production. The university’s estimates range from 3 to 12 % based on country and scenario, which would require 4 to 175 million m² of collector area in each of the four nations. The solar share of all four was rather similar in high penetration scenarios, although climate, energy demand and network design vary significantly. That’s why the researchers from Aalborg concluded that “the findings can be applied to a variety of energy systems, including in countries that are not directly part of this study.” They also underlined the importance solar thermal could have in reducing pressure on scarce resources such as biomass.
