The Sun Orbit GmbH is a start-up company with headquarters in Hettingen, in the Swabian Alb. The company specializes in the production and sales, as well as the continuous development and perfecting of multifunctional solar systems for local autonomy in rural and urban environments.
One focus is on the combined production of quality organic food and energy (electricity, mechanical energy, refrigeration, process heat), if possible under a climate envelope that can reach on one hand, the optimum PAR spectrum for plant growth in the interior and on the other hand, the portion of the solar spectrum that can not be used for plant growth is converted into the aforementioned forms of energy. For this application, Sun Orbit has developed a simple design for an efficient low-temperature Stirling engine "Sunpulse". This machine has worldwide USPs and opens new perspectives for solar energy, biomass and waste heat recovery.

The reasons for the technical and economic advantages of Sun Orbit system lie in the heart, the low temperature "Sunpulse" -Stirlingmotor. It is the result of years of intensive research and development work in the field of thermodynamic solar equipment, particularly of Stirling engines.

The Sunpulse systems and energy technologies related to the Envelope Power Greenhouse (EPG) are the two key technologies of the Sun orbit. Through their combination, Total Energy Systems are flexible and adaptable to local conditions.
