IEA SHC: Industry Workshop in Spain Shows Solar Cooling’s Global Opportunities

Submitted by Baerbel Epp on April 30, 2016
Task 43 WorkshopThe latest R&D developments in solar cooling presented during a workshop in Madrid, Spain, on 11 April sparked great interest among the attendees from the international air conditioning industry. Held at the headquarters of the Spanish Institute for Energy Diversification and Saving, IDEA, the event brought together representatives from companies, such as Baxi Roca, Carrier, Fujitsu, Kaysun and Panasonic, as well as researchers from Task 53, New Generation Solar Cooling and Heating Systems, of the IEA Solar Heating and Cooling Programme. The presentations showcased innovative solutions driven by solar heat or solar power. The experts agreed that solar cooling will be a market for both solar thermal and solar PV solutions over the coming years and will capture new territory outside Europe, such as in the Middle East or China. A current study on the Arab region concluded: PV cooling technologies are more economical than grid-driven electric chillers at cooling loads of 100 kWc, whereas solar thermal cooling should be used for 1 MWc cooling.

Big Ups and Downs on Global Market

Submitted by Baerbel Epp on April 26, 2016
The global solar thermal market went into another year of notable decline in 2015. With 37.2 GWth, the newly installed glazed and unglazed collector capacity in the 18 largest countries was 14 % lower than in 2014 (43.4 GWth). Between 2013 and 2014, the decrease in these 18 major countries – which represent 95-97 % of the world market – had been 15 %. The further slowdown last year was the result of diminishing collector area figures in China (-17 %), and in Europe (nine biggest nations down by -5 %). The countries with the highest growth rates last year were Denmark (+55 %), Turkey (+10 %), Israel (+9 %) and Mexico (+8 %). The chart shows both 2015’s newly installed collector area, broken down by collector type – flat plate, vacuum tube and unglazed collector area, and the 2014-2015 growth rate (excluding China, whose 2015 market volume was 21-times larger than Turkey, which ranked second). China added 30.5 GWth in 2015 of which 12.6 % were flat plate collectors (5.5 million m2).

Latest Market Statistics from Spain: “We need a public commitment to comply with the national targets”

Submitted by Baerbel Epp on April 24, 2016
After two years of slight improvement, the Spanish market reached 169 MWth (241,165 m2) of solar thermal capacity in 2015, which meant a 5.5 % drop compared to 2014. This is the result of a market study published by the Spanish solar thermal association, ASIT, in March 2016. The main reason for the disappointing sales figures was the lack of new construction and a poor performance by Andalusia’s regional incentives, which came to a halt in June 2015. The 2016 outlook, however, is another story: Spain has recently seen an upturn in the economy and construction segment and a growing number of unsubsidised systems. The Spanish solar thermal sector generated a revenue total of EUR 193 million in 2015 and provided employment to 4,800 workers.

Certification – A Marketing Tool for Solar Thermal Energy Professionals

Submitted by Baerbel Epp on April 11, 2016
To have a solar thermal system on the roof of one’s home may be a good thing if it does work well. But the probability that solar water heaters perform as they should and as long as they are supposed to is higher when they are installed by real experts familiar with the best practices of the industry. But how is one to know whether an installer is a real professional? Certification may be a viable indicator of whether or not a plumber can be trusted with installing a modern solar thermal system. That is why certification is gaining importance not only in manufacturing, but also in other parts of the industry. 
 

Europe: 23 New and Upgraded Solar District Heating Plants of 190 MWth Start Operation in 2015

Submitted by Baerbel Epp on April 5, 2016
District Heating EuropeAs in previous years, Denmark remained the country dominating Europe’s solar district heating market. Twenty of the 23 new and upgraded district heating plants in Europe above 350 kWth (500 m²) from the statistics compiled by Jan-Olof Dalenbäck from the Chalmers University of Technology, Sweden, went into operation in Denmark – whereas Austria, Italy and Sweden had only one each to show for. Dalenbäck’s database shows 211 large-scale district heating plants currently in operation, with combined output at 708 MW (1.01 million m²). This means that only every fourth district heating plant in Europe uses solar energy compared to the 5,400 district heating systems a database from Swedish Halmstad University lists from across the EU-27. The map shows 2,188 cities with 2,445 larger district heating systems. The highest plant densities can be found in Denmark, Poland, the Czech Republic and Slovakia.

Europe: Solar Keymark Network to Improve Complaint Procedures

Submitted by Baerbel Epp on March 31, 2016
The Solar Keymark Network has decided to establish a working group in order to revise and improve the complaint procedures and put them into one document, as they have so far been described in several different papers and various articles: The Solar Keymark Scheme Rules, Article 2.2, includes instructions on how to handle complaints and there is Article 6.3. Special Test, whereas the CEN-CENELEC Internal Regulations Part 4, Article 7.4, describes the appeal procedures (see the attached documents). This move is deemed necessary because at the end of 2015 – for the first time since the Solar Keymark label was launched – several complaints were submitted to one of the empowered certification bodies. “In our network meeting, we informed the members about the first big complaint and discussed the need for putting the complaint procedures into one document, to make it clearer for the solar thermal industry how to use them,” said Jaime Fernández González-Granda, Chairman of the Solar Keymark Network and Product Officer at the Spanish certification and standardisation body, AENOR. 
 

IEA SHC: Task 56 Kick-Off Meeting on Building Integrated Solar

Submitted by Baerbel Epp on March 30, 2016
Norway AventaAlmost 30 experts from 25 partner organisations met in Bolzano, Italy, on 21 and 22 March for the kick-off meeting of IEA SHC Task 56, Building Integrated Solar Envelope Systems for HVAC and Lighting. The overall goal of the task is to find out “why some ways of solar integration do work, while others don’t,” as the Task Operating Agent and Coordinator of the Sustainable Heating and Cooling Systems research team at Italian institute EURAC, Roberto Fedrizzi, put it – and, of course, to find measures to improve solar technology integration into façades and roofs. The photo shows a residential home in Stavern, southern Norway, where 7 m2 of solar collectors have been integrated into window frames in the south-facing facade, contributing to both domestic hot water preparation and space heating.

Cuba: Solar Water Heating Could Reduce Pressure on Power Grid

Submitted by Baerbel Epp on March 22, 2016
CubasolarLuis Hilario Bérriz Pérez, President of the Cuban Society for the Promotion of Renewable Energy Sources (CUBASOLAR) has recently pointed out that 89 % of the island’s population had access to hot water, 80 % of them by using electric heaters mainly during peak hours, as Cuban radio Rebelde has cited the renewables expert. Hence, Bérriz Pérez wants to start using existing technology – namely solar water heaters produced in Cuba – on a major scale in order to take some pressure off the Cuban electricity grid. The figure shows the model of a solar water heater made in Cuba; it was taken from a guideline published by Bérriz Pérez in 2008.
