NPV, IRR and DDP: The language of bankers and investors

Submitted by Baerbel Epp on March 27, 2018
Chart: Patrick ReiterIndustry professionals often do not use the same language as bankers and investors when they present solar thermal projects. We have asked Patrick Reiter, who has just finished his master’s thesis, titled Solar District Heating – Economic feasibility of large-scale solar thermal systems in municipal district heating networks – a case from Austria, to explain the most important words and key performance indicators, or KPIs, for the financial feasibility assessment of large-scale solar thermal plants. He studied for his master’s degree at the University of Graz’s Institute of Systems Sciences, Innovation and Sustainability Research.

Solar thermal and biomass – a winning solution for district heating

Submitted by Baerbel Epp on March 18, 2018
Photo: Riccardo BattistiBiomass may be cheap and carbon-neutral, but a solar upgrade of biomass-fired district heating could further improve efficiency and reduce local emissions. For example, solar heat helps avoid having to start up and shut down wood-chip boilers or operate them at partial load. It can even replace backup fossil fuel systems, which provide district heating networks with energy in summer. During a December 2017 webinar, held as part of the Horizon 2020 project SDHp2m…From Policy to Market, experts from Sweden and Austria showed promising case studies for a clever combination of biomass and solar thermal in district heating.

Financial support for concentrating solar systems extended until 2020

Submitted by Baerbel Epp on March 14, 2018
Photo: HoneywellThe “order” published by the Indian Ministry of New and Renewable Energy on 26 February 2018 put an end to the uncertainty which had pervaded the industry. In the 2-page document, the ministry pledged to continue its investment subsidy programme for concentrating solar thermal systems. The target until March 2020 is 90,000 m² of collector area. The financial year 2017 to 2018, during which 20,000 m² were planned to be subsidised, is almost over.

India: Flat plates up, concentrating technologies down

Submitted by Baerbel Epp on March 1, 2018
Source: Jaideep MalaviyaIn 2017, India’s solar thermal market shifted heavily in favour of flat plate collectors, with systems based on concentrating technologies losing ground. The chart shows the annually installed flat plate collector area to have more than doubled last year compared to 2016. It went from 150,476 m² (105 MWth) to 397,286 m² (278 MWth) an increase by 164 %. Installation figures for solar water heaters based on imported vacuum tubes rose by 7 % to 1,120,963 m² (785 MWth). Concentrating collector sales, on the other hand, only added 5,450 m² to the total, a much lower value than the 26,040 m² in 2016. The reference period for the annual statistics was changed in 2016. It is now the calendar year, whereas it used to be the Indian financial year, which runs from 1 April to 31 March the following year.

Solar district heating on the Roof of the World

Submitted by Baerbel Epp on February 27, 2018
Photo: Task 55A contract to set up a solar district heating network in Langkazi county in Tibet has been awarded to Arcon-Sunmark Large-Scale Solar Systems. The Chinese-Danish joint venture signed an agreement with the local government of the autonomous region of Tibet. The system should provide solar district heating for 82,600 m² of floor area and meet 90 % of the yearly space heating demand in Langkazi, the town sharing its name with the county. The system, planned to be set up by November, will consist of a 22,000 m² collector field, 15,000 m³ of pit storage and a 3-MW electric boiler. The sponsor of the pilot project is China’s central government.

Germany: Solar thermal loses out to other renewables

Submitted by Baerbel Epp on February 20, 2018
Wagner & Co2017 was the weakest year for solar thermal collector sales in more than a decade, according to the combined statistics by associations BDH and BSW-Solar. Their data reveals that only 78,000 systems were sold last year. The newly installed collector area added up to 625,000 m², down 16 % from 2016 and as much as 72 % from the boom year of 2008. It was an astonishingly poor showing, considering the strong growth in the construction industry and the high incentive amounts available in Germany.

Thermosiphon market rebounds in Italy

Submitted by Baerbel Epp on February 16, 2018
Photo: Riccardo BattistiSystem suppliers and importers in Italy have reported significant growth in thermosiphon sales in 2017 thanks to the national support scheme Conto Termico 2.0. “Compared to the previous year, we more than doubled the number of thermosiphon units we sold in Italy in 2017, and most systems had a larger collector area because of the level of subsidies from Conto Termico 2.0,” said Export Sales Manager Andreas Andrianopoulos from Greek-based solar thermal manufacturer Cosmosolar.

Solar to replace coal in Polish district heating networks

Submitted by Baerbel Epp on February 7, 2018
NFOŚiGWZbigniew Kamieński, adviser to the president of NFOŚiGW’s board, has recently made some encouraging statements. During the conference Use of renewable energy sources and seasonal heat storage in district heating in Warsaw on 17 January, he said that the proposal of a new subsidy programme for renewable district heating deserved attention and implementation. The conference with nearly 130 attendees was organised jointly by NFOŚiGW, the National Fund for Environmental Protection and Water Management, and IEO, the Institute for Renewable Energy, and was supported by the SDHp2m project

1,500 preheating systems in India’s silk region

Submitted by Baerbel Epp on January 23, 2018
Photo: Jaideep MalaviyaSolar process heat has gained popularity in the centre of India’s silk production – more specifically, in Sidlaghatta, a town in the southern state of Karnataka. The statistics of Karnataka’s Department of Sericulture shows that a little over 1,500 units between 2 and 10 m² have been switched from wood or briquettes to solar for preheating the traditional stoves. The Department of Sericulture has been promoting the technology among silk producers by providing a 75 % subsidy for any reeling unit partly heated by solar energy. The use of sunlight can cut firewood consumption in half.
