Ambassador visits the first solar thermal energy plant in Southeast Asia

Duckwitz, (PresseBox) - Dr. Hanns Heinrich Schumacher, the German Ambassador to Thailand, visited the first solar thermal energy plant currently under construction in Thailand. Located in the province of Kanchanaburi northwest of Bangkok it is the first commercial parabolic trough plant in the world to use direct steam generation to achieve an output of 5 MWe. Solarlite GmbH is also the first company in the world to build plants with this technology.

The German Ambassador to Thailand, Dr. Hanns Heinrich Schumacher, visited the "TSE 1" solar thermal energy plant under construction in Kanchanaburi Province northwest of Bangkok on March 11, 2011. He was accompanied by Stefan Duppel, Regional Counsellor and Deputy Ambassador, and Dr. Thomas Multhaup, who heads the Embassy's Economic and Trade Division.

This 5 MWe plant is the first commercial parabolic trough plant in the world to use direct steam generation from water. This technology is more efficient, less expensive and more environmentally friendly than conventional systems, which use thermal oil and an additional heat exchanger.

Solarlite GmbH, based in Duckwitz, Mecklenburg-West Pommerania, is the only company in the world that offers this technology for commercial applications. Solarlite GmbH executives Joachim Krüger and Moritz von Plate were on site to explain the project and lead the delegation through the various production stages, such as the positioning of individual segments and the welding of the receivers.

The German Ambassador and his accompanying delegation were impressed not only by the size of the facility (an area of 110,000 m2) but the precision work required to build it. The fact that technology "made in Germany" is creating jobs and added value in Germany and Thailand is a definite plus.

Dr. Schumacher assured Solarlite GmbH of his assistance in making the Thai government aware of "solar thermal power." On that note, Joachim Krüger said, "It is important to also draw attention to German companies whose entrepreneurial activities are primarily carried out abroad. That is why I am pleased that the German Ambassador, Dr. Schumacher, as well as Mr. Duppel and Dr. Multhaup are the first official visitors of our project and are learning more about it on site."

Solarlite is a pioneer in this industry in Southeast Asia. The company has become a leader in the market, particularly in Thailand, due to its sustained and intensive networking efforts.

Solarlite GmbH

Solarlite GmbH develops and builds decentralized solar thermal parabolic trough plants (CSP- concentrated solar power) for combined heat and power generation. These power plants have an electrical output in the range of 500 kWe to 30 MWe. Solarlite is the only supplier of parabolic trough plants in this segment. Compared to conventional parabolic trough collectors, the direct steam generation implemented by Solarlite is more efficient, less expensive, and more environmentally friendly. Solarlite GmbH (German limited liability company) was founded by Joachim Krüger in 2007. The first-ever commercial 5 MWe solar thermal parabolic trough power plant based on direct steam generation is being built in Thailand. The plant will begin operations in the first half of 2011.

Short description of the innovative technology and applications

Product description
The Solarlite 4600 parabolic trough is a newly developed highly efficient product that can generate temperatures of up to 400 °C. Each panel has an aperture width of 4.6 m and is made of composite materials combined with an efficient thinglass mirror. This mirror reflects up to 95% of the sun’s radiation onto the absorber pipe positioned at the ideal focus of the parabolic mirror. Water passing through the absorber pipe is heated up by the concentrated reflected sun radiation and is converted into steam in a controlled process. A turbine generator produces electricity. Residual Heat can be used for other applications like seawater desalination or absorption cooling.
The main competence of Solarlite is the knowledge around the production of parabolic troughs made of composite material at high precision for mass-production, which makes it more profitable to build smaller plants worldwide.

Solarlite Technology
A new phase in the development of solar technology has been reached with the Solarlite technology. The modular design based on combining a light composite construction and an efficient thinglass mirror is advantageous in various aspects, for example a central production independent of the power plant sites allowing different project sizes with no limitations.
The direct steam generation of water instead of thermal oil and the option of cogeneration of thermal and electrical energy makes the energy production highly efficient and environmentally friendly.
Solarlite technology is able to reduce total investment costs of a power plant project and guarantees attractive prices as well as a reliable source of energy.
