Solar-driven Water Treatment Experiences in India (2014)

Submitted by Raquel Ponte Costa on September 5, 2014

This presentation on solar-driven water treatment was given by SolarSpring’s Dip.-Ing. Lorenz Bauer at Intersolar Europe in June 2014.  After a short introduction on SolarSprings’ products and activities, the speaker presented 4 different solar water treatment projects that were conducted in India. These 4 projects use specific solar disinfection systems and their aim is to provide sufficient safe drinking water to the communities’ populations and create an optimized municipal waste water treatment.

Germany: Dutch Solar Systems Set to Take Over Wagner

Submitted by Baerbel Epp on September 4, 2014
Dutch Solar Systems (DSS), located in Enschede, is negotiating with the insolvency administrator, Markus Plathner, to take over German collector manufacturer Wagner & Co Solartechnik, as the Managing Director of the Dutch wholesaler and project planning company for photovoltaic, solar thermal and heat recovery systems, Brigitte van Egten, confirmed to German newsletter Solarthemen. Wagner, which was founded in 1979, filed for bankruptcy on 22 April 2014. The details of the proposed deal are still sketchy: No contracts were signed until the editorial deadline on 4 September, although the takeover date had originally been set to 1 September. 
 

Denmark: Solvarmedata.dk Shows Yields of More Than 40 Solar District Heating Plants

Submitted by Baerbel Epp on September 3, 2014
solvarmedata mapThe interactive map on www.solvarmedata.dk, a website operated by agency Easynet, shows yield information entered by more than 40 solar district heating companies. The data also includes the irradiation figures and for most plants, even the hourly results of past years. The website was the brainchild of Per Kristensen, who came up with the idea when he was director of Braedstrup Fjernvarme. The screenshot shows the website’s first page.
 

Germany: Merger between Alanod and Almeco Fails

Submitted by Baerbel Epp on September 2, 2014
Alanod-AlmecoRarely has a press release by German coating specialist Alanod been this short: The statement to take the solar thermal industry by surprise was only three sentences long. “The shareholders of [Alanod Group and Almeco Group] have agreed to utilise the limited opt-out clause till the end of August. Regarding further details, both companies agreed to observe secrecy. For the future, Alanod and Almeco will be competitors again and are respecting each other, in order to continue supplying their customers as a reliable partner on a long-term basis,” it said on 14 August 2014. And rarely has the solar thermal industry had so little knowledge about why a merger failed. Alanod-Almeco, with headquarters in Ennepetal, had just been announced three months ago in June, right before the Intersolar Europe conference began.
 

Denmark: 37 MW Field with 203,000 m³ Storage Underway

Submitted by Baerbel Epp on August 30, 2014
Vojens Seasonal StorageConstruction has begun on another large-scale installation: This time, the new number one solar thermal plant in the world will be in Vojens, a small town in southern Denmark, near the city of Kolding. The customer is Vojens District, which signed a contract with Danish collector manufacturer Arcon Solar this May about delivering and installing a 37 MWth collector field (52,491 m²). The 4,166 collectors will all be produced in Arcon´s factory in Aalborg. At present, the seasonal pit heat storage with 203,000 m³ is underway: Vojens District is uploading pictures once a month and the ones from August show the lining of the huge water-filled basin with high-density polyethylene foil (see photo). The currently largest solar thermal plant, a 26 MWth installation with 61,700 m³ of seasonal storage, is located in the Danish town of Dronninglund.

Nevada: Solar Thermal Water and Space Heating : 2014 Program Handbook (2014)

Submitted by Raquel Ponte Costa on August 29, 2014

NV Energy, a major energy company in Nevada, was authorized in 2010 by the Public Utilities Commission of Nevada to start an incentive program, called the Solar Hot Water Program, for its customers willing to install solar hot water systems. NV Energy has published a handbook which provides information on the background of this program and also explains the eligibility criteria.  The document enumerates the different steps to follow to submit a dossier and gives information on the incentive's calculation methods.

USA: S.O.L.I.D. Operates 3.4 MWth Cooling System as ESCO in Arizona

Submitted by Baerbel Epp on August 29, 2014
Desert Mountain High SchoolIt is an ideal location for solar cooling use: Scottsdale, a US city in the Greater Phoenix area in Arizona enjoys an average of 312 days of sunshine every year. Between May and September, temperatures rise above 38°C and can even reach 46°C on a hot day. This is where in July 2011, Austrian company S.O.L.I.D has started to plan a solar cooling system for Scottsdale’s Desert Mountain High School (DMHS) of 2,600 students. Three years later, the 3.4 MWth (4,865 m² of collector area) system went into operation and is now supplying heat to a single-effect lithium bromide absorption chiller with a cooling capacity of 1,750 kW. The solar cooling installation at the DMHS is currently the largest of its kind in the world, having surpassed the 2.7 MWth solar thermal capacity (3,900 m²) of another S.O.L.I.D system at the United World College (UWC) in Singapore.

South Africa: Fresnel Collectors Keep It Cool in MTN’s Server Rooms

Submitted by Baerbel Epp on August 28, 2014
Industrial SolarSince June 2014, a Fresnel collector field with 242 kWth has been feeding into the district cooling system of the MTN Group at its headquarters in Johannesburg, South Africa. MTN, which has more than 200 million customers, as well as subsidiaries in 22 countries across Africa and the Middle East, is one of the leading mobile operators in South Africa – and it is aware of the impact of global warming. “We continuously explore ways in which we can lessen the impact of our operations on the environment. This initiative will not only reduce our carbon footprint but it will substantially reduce our electricity consumption, which will release additional capacity for the national grid,” MTN’s CEO, Zunaid Bulbulia, was quoted as saying in a press release from 17 July 2014. The concentrating solar thermal plant powers the double-effect absorption chiller whose cooling capacity of 330 kW keeps temperatures low in the data centre at MTN’s head office.

China: Engineering Segment Drives Solar Thermal Market

Submitted by Baerbel Epp on August 27, 2014
China building integrationThe make-up of China’s solar thermal market is changing: The segment that used to guarantee the industry’s profits, the retail business of small thermosiphon systems for private households, has been declining in recent years. Other solar thermal segments, however, have been taking off in the meantime – for example, the market for more sophisticated solar thermal installations that are integrated into blocks of flats, hospitals, schools or universities. There is also growing interest in medium- and high-temperature solar thermal systems for industrial process heat. According to the annual surveys and market reports by Sun’s Vision, a consultancy located in Shandong province, the so-called solar thermal engineering market, which includes building integration and industrial process heat systems, increased by 50% in 2012 and 2013, after having grown by 35 % in 2011. The pie chart shows the individual categories of the building integration segment in 2013, which was the main driver of the national market.
