1 Future of energy: solar thermal energy Alejandro Campos Fischer General Manager, Paradigma Iberica

2 The ecological disaster of Chernobyl (1986) was the motivation of our principal shareholder to invest in alternative and renewable energy sources. For more than 20 years, the Ritter Group contributes to greater energy efficiency and sustainable climate protection by offering ecological energy solutions. Economic activities can, in the long run, only be successful if they are in conformity with mankind and nature. Alfred T. Ritter

3 Facts and figures ,600 companies in 9 countries divisions: Private customers OEM business Large scale solar thermal systems employees worldwide from which 390 in Europe 143 million Euro Sales 1.9 million m² collector area sold worldwide 3.1 % market share in the global solar thermal market by Ritter Energie- und Umwelttechnik GmbH & Co. KG VN V /2012 Technische Änderungen vorbehalten 3

6 On a large scale Large scale solar thermal systems Ritter XL Solar Ritter Group USA 200 RXLS solar thermal systems have been realised, including some of the largest in the world by Ritter Energie- und Umwelttechnik GmbH & Co. KG VN V /2012 Technische Änderungen vorbehalten 6

7 Made by Ritter Gruppe Ritter Solar Dettenhausen, Deutschland Vacuum tube collectors for the European market. Linuo Paradigma Jinan, China Solar thermal systems for the Chinese and international market. The production focusses mainly on thermosiphon systems. Prükom St. Leon-Rot, Deutschland Register for vacuum tube collectors. RNO Kesselfabrik Dettenhausen, Deutschland Wood pellet boilers for the European market by Ritter Energie- und Umwelttechnik GmbH & Co. KG VN V /2012 Technische Änderungen vorbehalten 7

8 Ritter Solar Technology AQUA-System High efficient: Vacuum tube technology with CPC mirror High temperatures: 120ºC, Bucket principle Durable (> 20 years): Water instead of anti-freezing compound Simple and reliable: Almost no moved parts, low maintenance Intelligent: Highly sophisticated controller

9 Engine: High efficient - CPC Evacuated Tube Collector

10 Feeding algorithm - the bucket principle Solar heat is collected and stored in the evacuated tubes of the collector If there is enough heat in the collector ( bucket is filled up) the pump is switched on and transfers the heat into the storage tank High solar supply temperature: min. 60 C, average 75 C, max. 90 C

11 Highlight Aqua - heat transfer medium - water Characteristic Unit Glycol mixture Water specific heat capacity, 20 C [kj/kg. K ] 3,65 (87 %) + 4,18 (100 %) ++ kinematic viscosity, 20 C [mm²/s] 5,0 (500 %) o 1,0 (100 %) ++ chemical durability [-] oxidation cracken - extreme consistant ++ purchasing and disposal [-] retail market dumpsite o tap drainage ++ gross price for 30 Liter [ ] 130,- ( %) -- 0,054 (100 %) ++ freezing point [ C] - 28 C ++ 0 C - overall comparison satisfactory o outstandig ++

12 Intelligent frost protection function Our solar system only uses water as a heat transfer medium The anti-freeze protection avoids that the water in the solar system freezes in case of low temperatures In case of low temperatures the pump connect in intervals depending on the collector sensor and the length of the pipe work outside Minimum energy input Acoustic warning in case of malfunction

13 As brilliant as it is simple : collector used as heating boiler New: Before: collector used as used heating as preheater! boiler!

14 NYPA Metro, New York, 2010 Washing plant for trains C Gross collector area 164 m² Buffer tank volume 15 m³ Max. continuous power 85 kw Yield / Year 105 MWh

15 District Heating, Austria, 2011 Support for district heating network 95 C Gross collector area m² Buffer tank volume 5 m³ Max. continuous power 1,7 MW Yield / Year MWh

16 Metro, Istanbul, 2009 Solar cooling and heating 95/75 C Gross collector area m² Buffer tank volume 15 m³ Max. continuous power 0,5 MW Yield / Year 650 MWh

17 Warehouse, Portugal, 2012 Domestic hot water 95/60 C Gross collector area 12 m² Buffer tank volume 1500 L. Max. continuous power 9,24 KW Yield / Year 11 MWh
