Solarlite CSP Technology GmbH, located in Mecklenburg-Pomerania, Germany, develops decentralized solar-thermal parabolic trough power plants (concentrated solar power) and process heat plants.
Solarlite has tested the direct steam generation (DSG) concept in three pilot projects in Thailand and Germany. The results indicated that a higher operating temperature may be achievable with DSG.
The Solarlite SL 4600 parabolic trough can generate temperatures up to 400°C. Each panel has an aperture width of 4.6 m and is made of composite materials combined with a thin glass 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.[ citation needed ] 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 then uses the steam to produce electricity. Residual heat can be used for other applications such as seawater desalination or for absorption cooling. [1]
The basic element of the Solarlite 4600 collector is the Solarlite composite panel, which has dimensions of 2.3 m width and 1 m length. These panels are combined together to form one segment with an aperture width of 4.6 m and 12 m length. It is possible to connect ten of these segments to form one collector, thus reaching up to 120 m in length. These collectors are combined together to form rows (collectors aligned in 1 axis in the north-south direction) and loops, which are collectors that are connected in series, where the cold fluid enters at one end and the hot fluid leaves at 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 lightweight composite and slender steel structure allows having a reduced specific weight compared to the competitors.
In 2012, Solarlite was forced to declare insolvency. According to BonVenture, the reason for this was "the unexpected market shift towards photovoltaics due to the Chinese government's subsidies policy and the non-fulfillment of contractual obligations and payments by two customers". [2] The company then reincorporated on January 1, 2013, as Solarlite CSP Technology GmbH with the same CEO, Joachim Krüger. [3]
Solarlite has tested the DSG concept in three pilot projects. Solarlite's adaptation of the DSG concept is based on the following advantages:
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:
Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry, and in the residential and commercial sectors. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature collectors. Low-temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air. Medium-temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use.
A parabolic trough collector (PTC) is a type of solar thermal collector that is straight in one dimension and curved as a parabola in the other two, lined with a polished metal mirror. The sunlight which enters the mirror parallel to its plane of symmetry is focused along the focal line, where objects are positioned that are intended to be heated. In a solar cooker, for example, food is placed at the focal line of a trough, which is cooked when the trough is aimed so the Sun is in its plane of symmetry.
Solar Energy Generating Systems (SEGS) is a concentrated solar power plant in California, United States. With the combined capacity from three separate locations at 354 megawatt (MW), it was for thirty years the world's largest solar thermal energy generating facility, until the commissioning of the even larger Ivanpah facility in 2014. It was also for thirty years the world's largest solar generating facility of any type of technology, until the commissioning of the photovoltaic Topaz Solar Farm in 2014. It consisted of nine solar power plants in California's Mojave Desert, where insolation is among the best available in the United States.
Nevada Solar One is a concentrated solar power plant, with a nominal capacity of 64 MW and maximum steam turbine power output up to 72 MW net (75 MW gross), spread over an area of 400 acres (160 ha). The projected CO2 emissions avoided are equivalent to taking approximately 20,000 cars off the road. The project required an investment of $266 million USD, and the project officially went into operation in June 2007. Electricity production is estimated to be 134 GWh (gigawatt hours) per year.
There are several solar power plants in the Mojave Desert which supply power to the electricity grid. Insolation in the Mojave Desert is among the best available in the United States, and some significant population centers are located in the area. These plants can generally be built in a few years because solar plants are built almost entirely with modular, readily available materials. Solar Energy Generating Systems (SEGS) is the name given to nine solar power plants in the Mojave Desert which were built in the 1980s, the first commercial solar plant. These plants have a combined capacity of 354 megawatts (MW) which made them the largest solar power installation in the world, until Ivanpah Solar Power Facility was finished in 2014.
The Andasol solar power station is a 150-megawatt (MW) concentrated solar power station and Europe's first commercial plant to use parabolic troughs. It is located near Guadix in Andalusia, Spain, and its name is a portmanteau of Andalusia and Sol. The Andasol plant uses tanks of molten salt as thermal energy storage to continue generating electricity, irrespective of whether the sun is shining or not.
Sopogy short for Solar Power Technology was a solar thermal technology supplier founded in 2002 at the Honolulu, Hawaii-based clean technology incubator known as Energy Laboratories. The company began its research on concentrating solar thermal energy to produce solar steam and thermal heat for absorption chillers or industrial process heat. The company has also developed applications that incorporate its solar collectors to generate electricity and desalination. Sopogy's name origin comes from industry key words "So" from solar "po" from power and "gy" from energy and technology. The company has its OEM and IPP sales teams along with research and development located in Honolulu, and in 2006 expanded its manufacturing, C&I and oil and gas sales teams in its Silicon Valley facility. Pacific Business News and Greentech Media reported that the VC-funded micro-concentrator solar power firm was shutting down operations based on statements from its President David Fernandez, however Hitachi Power Systems acquired Sopogy in a private transaction in 2014.
The Solana Generating Station is a solar power plant near Gila Bend, Arizona, about 70 miles (110 km) southwest of Phoenix. It was completed in 2013. When commissioned, it was the largest parabolic trough plant in the world, and the first U.S. solar plant with molten salt thermal energy storage. Built by the Spanish company Abengoa Solar, the project can produce up to 280 megawatts (MW) gross, supplied by two 140 MW gross (125 MW net) steam turbine generators: enough electricity to meet the needs of approximately 70,000 homes and obviate the emission of roughly 475,000 tons of CO2 every year. Its name is the Spanish term for "sunny spot".
Concentrated solar power systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight into a receiver. Electricity is generated when the concentrated light is converted to heat, which drives a heat engine connected to an electrical power generator or powers a thermochemical reaction.

A compact linear Fresnel reflector (CLFR) – also referred to as a concentrating linear Fresnel reflector – is a specific type of linear Fresnel reflector (LFR) technology. They are named for their similarity to a Fresnel lens, in which many small, thin lens fragments are combined to simulate a much thicker simple lens. These mirrors are capable of concentrating the sun's energy to approximately 30 times its normal intensity.
