Italy: “Conto Termico is under revision and an improved version should come into force before summer”

Submitted by Baerbel Epp on May 1, 2015

According to the market survey by Assotermica, the Italian Association of Manufacturers of Equipment and Components for Heating Systems, Italy’s newly installed collector area went down to 280,000 m2 last year. The survey covers about 80 % of the market, with the remaining share having been extrapolated. In search of an explanation for the apparently relentless market collapse since the peak year of 2008, during which 500,000 m2 were installed, solarthermalworld.org spoke with Federico Musazzi, Secretary General of Assotermica and Official at roof organisation ANIMA, the Federation of the Italian Associations of Mechanical and Engineering Industries.

Solar Cooling Week in China: Sector Still Growing in Asia and Europe

Submitted by Baerbel Epp on April 30, 2015
Solar Cooling WeekSolar thermal cooling is a “small, but steadily growing market,” Dr Uli Jakob from the Green Chiller Association for Sorption Cooling pointed out in his presentation Solar Air-Conditioning in Europe during the Solar Cooling Week, which took place in Shanghai from 23 to 27 March. The week started with two experts meetings of IEA SHC Task 48 (Quality Assurance and Support Measures for Solar Cooling Systems) and Task 53 (New Generation Solar Cooling and Heating Systems) on solar cooling and ended with the Solar Cooling Conference. About 80 % of the over 100 participants came from Asian countries. Conference Chairman Daniel Mugnier (see photo) thanked “Shanghai Jiao Tong University – and especially, Professor Yajun Dai  for having organised “a perfect Solar Cooling Week.”

Frontrunner in Solar Obligations in Africa

Submitted by Baerbel Epp on April 28, 2015
The government of the East-African country approved the so-called Energy (Solar Water Heating) Regulations 2012, which were gazetted on 25 May that year. The Energy Regulatory Commission (ERC) is implementing a number of measures to support the implementation of the ordinance.

Kenya: Financial Scheme Attached to Solar Obligation

Submitted by Baerbel Epp on April 28, 2015
Solimpexs AfricaKenya is the frontrunner in solar obligations in Africa. The government of the East-African country approved the so-called Energy (Solar Water Heating) Regulations 2012, which were gazetted on 25 May that year (see the attached PDF). The Energy Regulatory Commission (ERC) confirmed that there “has been significant growth in solar thermal” since the solar obligation came into force. The financial institutions have also jumped on the solar bandwagon recently and are creating asset finance solutions to make solar water heating systems affordable. One of them is Housing Finance, a firm quoted on the Nairobi Stock Exchange. The company started the SolaPawa programme in March 2015 to focus “primarily on the provision of financing for solar water heating systems for both domestic and commercial entities,” Achieng Oluoch, Head of Marketing at Housing Finance, explains. “Our objective is to enable individuals and institutions to comply with this law in a convenient manner.”

Germany: Crowd Lending or Cooperatives – Different Ways to Bring Solar District Heating into Focus

Submitted by Baerbel Epp on April 24, 2015
Trier SolarvereinRenewable heat comes out on top whenever it substituted fossil energy, Swiss solar thermal pioneer Josef Jenni stated during the first panel discussion of the conference on district heating with solar and biomass, which was held in the German city of Trier on 16 and 17 April 2015. Organised by the local solar association, Solarverein, it provided a platform for experts from small and medium-sized industrial companies, universities and research institutes based in Germany, Switzerland, France, Denmark, Austria and Luxemburg to work on turning this objective into a reality by focusing on viable business models of renewable use in district heating systems.

Design, Development, and Performance Evaluation of Solar Heating System for Disinfection of Domestic Roof-Harvested Rainwater (2014)

Submitted by Francesco Gattiglio on April 23, 2015

This research article proposes the use of a box-type solar heater for the disinfection of domestic roof-harvested rainwater in Ibadan, Nigeria. Solar water heater can be used to pasteurize water thereby destroying bacteria and viruses when heated to temperatures of about 65°C.

Austria: Business as Usual Results in Market Decline

Submitted by Baerbel Epp on April 20, 2015
AEE Intec Chart 1If the Austrian solar thermal sector keeps doing business as usual, newly installed collector area will continue to decrease and end up at 122,000 m² in 2025 (152,000 m² in 2014), while collector area in operation will stagnate at around 5 million m² (4.18 million m² at the end of 2013). This is the key message of the Austrian roadmap Solarwärme 2025 (Solar Heat 2015). In their study, Christian Fink and Dieter Preiß, both from Austrian research institute AEE Intec, conclude that the downward trend is a result of shrinking demand from owners of single- and two-family buildings, especially regarding existing building stock. It seems as if the demand from the ecologically aware clientele has already been met, and it needs new marketing strategies to target other homeowners.

IEA SHC Task 46: Solar Irradiation Data Helps Schedule and Operate Solar Thermal Plants

Submitted by Baerbel Epp on April 19, 2015
Irradiation ChartIEA SHC Task 46, Solar Resource Assessment and Forecasting, is an SHC project conducted in cooperation with IEA’s SolarPACES for Concentrating Solar Power and the Photovoltaic Power Systems programme. Accurate assessment and forecasting of solar irradiation is a key issue in planning and operating solar electricity and solar thermal plants. Task 46 has been evaluating various forecasting models and standardisation procedures for irradiation measurement, for example, regarding detail and accuracy. Numerical Weather Prediction and cloud models based on satellite images (CM-sat) with their up-to hourly resolution are detailed enough for rough estimates of solar generation capacities within the next hours and days. Grid integration and power plant control, however, require algorithms based on CM-SI (Cloud Models based on Sky Imaging) time-series modelling to forecast irradiation seconds or a few hours away (see figure on the left).

India: PRINCE Offers Solar Cooking Workshops for New Entrepreneurs

Submitted by Baerbel Epp on April 17, 2015
Prof. Ajay ChandakIndian organisation Prince – Promoters, Researchers and Innovators in New and Clean Energy – is offering training workshops on residential and institutional solar cooking to new entrepreneurs who manufacture or trade solar cooking systems. PRINCE has already conducted more than twelve workshops, and according to the organisation, more than 60% of the solar dish cooker manufacturers and suppliers registered with the Indian Ministry of New and Renewable Energy (MNRE) have benefitted from PRINCE’s training courses. The photo shows Professor Ajay Chandak, founder of PRINCE and Board Member of the International Solar Energy Society (ISES), demonstrating an improved cooker model during a workshop in February 2015.
