Solarlite CSP Technology GmbH, located in Mecklenburg-Pomerania, Germany, develops and builds decentralized solar-thermal parabolic trough power plants ( CSP – Concentrated Solar Power) and process heat plants. For the first time worldwide, Solarlite is using direct steam generation commercially in a power plant.Solar thermal facilities offer the most sustainable form of energy recovery in terms of the environment, resources and availability. The technology has the advantage that as direct solar radiation increases, so does the efficiency of the facilities. The facilities are also characterized by a high degree of flexibility. They can be combined with all other fossil and renewable energy sources and are thus base-load capable. Another plus is the option of producing electricity and process heat at the same time or independently of one another. In addition, the residual heat can be used for further industrial applications for example desalination and cooling.
The first commercial solar thermal parabolic trough power plant with Direct Steam Generation in the world is producing electricity since Fall 2011. The 5 MWe solar thermal power plant located in Kanchanaburi/Thailand is unique in three different ways.

Solarlite has tested the DSG concept successfully in three pilot projects in Thailand and Germany. The DSG concept is environment friendly and allows significant reductions of the total
investment costs and levelized electricity cost. With DSG a higher operating temperature will be achievable.
The Solarlite SL 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.

Direct steam generation

Solarlite has tested the DSG concept successfully in three pilot projects in Thailand and Germany. Solarlite’s adaptation of DSG concept is based on the following advantages:

Direct steam generation 2.0

Flow path concept, development and testing - In a joint research project known as “Duke” that was supported by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, Solarlite CSP Technology GmbH and the German Aerospace Centre tested a new version of direct steam generation. Project aim

SL 4600+

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 receiver pipe positioned at the ideal focus of the parabolic mirror. Water passing through the receiver pipe is heated up by the concentrated reflected sun radiation and is converted into steam within a controlled process. A turbine generator produces electricity. Residual heat can be used for other applications such as seawater desalination or absorption cooling. The basic element of the Solarlite 4600 collector is the Solarlite composite panel which has a dimension of 2.3 m width and 1 m length. These panels are combined together to form 1 segment with a dimension 4.6 m aperture width and 12 m length. It is possible to connect 10 of these segments to form one collector thus reaching up to 120 m. These collectors are combined together to form rows (collectors aligned in 1 axis in the North-South direction) and loops (collectors connected in series where the cold fluid enters in one end and the hot fluids leaves in the other end). The collector is moved from east to west to track the sun by means of a hydraulic drive system. The modular concept of Solarlite allows choosing the optimal length of the collector based on the specific locations’ wind data. The combination of the light weight composite and slender steel structure allows having a reduced specific weight compared to the competitors.
