A bivalent operation


SOLITEM’s System Idea

A tariff dependant operation

• High tariff zone:– Electricity is expensive– Replacing of electricity costs by mainly producing

coldness

• Low tariff zone:– Electricity is less expensive– Reducing of coldness production in favour of an

extensive process steam generation (saving fossilfuels)

Increasing the overall efficiency significantly!

SOLITEM solar systems with parabolic trough collectors PTC 1800® make an importantcontribution to reduce fossil energy consumption and to avoid CO2- emissions.

The investment for the systems will return within few years by saving costs of fossil fuels. So thesystems have not only excellent ecologic but also high efficient economic qualities.


The system developed by SOLITEM firstly makes world wide roof mounted parabolic troughcollector fields possible, for the application in holiday hotels and facilities as well as in hospitals tosupply steam consumers, air conditioning and combined with ORC Plant installations by solarenergy.


Technical progress increases energy consumption. The technical progress improve the chanceof renewable energy systems in the economic competition with fossil energy.


The SOLITEM team has long term experiences in distributed and renewable energy systems.Energy, heat and process engineering are main competences of SOLITEM. They are completed bycurrent experiences and topical know how of energy conversion and energy application.


SOLITEM develops in addition to collectors also electronic devices of control and monitoringsystems as well as software programs for tracking and controlling of collectors with our teamin Germany.


SOLITEM develops also some other applications of PTC e.g. desalinisation plant (freshwaterproduction from seawater) where PTC combined with capillary structures.

This way open a new perspective for using of solar energy in different countries and areas.
