Solarlite 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 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.

Solarlite 2300

The smaller Version Solarlite 2300 is the first by Solarlite developed parabolic trough which produces steam and temperatures up to 400 °C. The innovation of this product is based on the materials used. It is made out of glass fibre reinforced plastic (FRP) which will enable Solarlite to achieve a compact lightweight and modular design and costs savings for installation, maintenance and transport. Each mirror element has a span of 2.33 m and a length of 1.0 m. The reflective surface consists of a layer of aluminium with high reflection efficiency.

• Solarlite parabolic troughs are installed in parallel rows.
• The number of mirror units depends on the required capacity of the plant.
• The collectors are automatically driven to follow the sun.
• A software calculates the optimum position of the mirror with the aid of GPS data.

The operating concept

The technology of solarlite Parabolic troughs is based on the concept of Concentrated Solar Power. The sun radiations are reflected by the mirrored surface on the absorber pipe positioned at the ideal focus of the parabolic mirror. The water passing in the absorber pipe is heated up by the concentrated reflected sun radiation and is immediately converted into steam.

The steam is fed into to a heat exchanger, where it can be used in various applications as per requirement. For a guaranteed continuous supply of energy the Solarlite system can be combined with biomass boilers or other steam generators.

This technology is economically interesting due to the fact that several processes can take place in succession, for example: Steam production-> Electricity generation -> Cooling -> Residual heat utilisation.
