About us!


Our History and Vision


Soltune is committed to carrying out all projects with the highest degree of integrity and confidentiality, and is committed to being honest in our dealings with our customers, our vendors and ourselves. Our experienced and highly skilled team assures that our projects are done with highest quality and in shortest possible time. Our passion for solving new challenges and our tireless focus on the solution of existing problems have enabled us to obtain excellent results within the CPV and space sector.

Soltune has successfully carried out several projects regarding R&D, product development and production of CPV products and space solar cells. Examples are:

  • Design, implementation and optimization of production lines for high-efficient III-V solar cells for CPV and space applications
  • Design, development and testing of CPV modules for electrical and/or thermal energy generation.
  • Strategic assessment (technical and economic) for the market introduction of novel products.

Our services range from short-term studies/audits to long-term projects.


Soltune CPV has been founded by Dr. Egbert Rodriguez Messmer in March 2012 and is based in Madrid (Spain).

Dr. Egbert Rodriguez Messmer holds a PhD degree from the Royal Institute of Technology (Sweden), a Master of Science degree in Electrical Engineering from the RWTH Aachen (Germany) and an MBA from the UNED (Spain). He is a certified project manager (PMP). His main interests are the development of technologies for generation of solar electrical and thermal energy, and its sustainable implementation into the existing energy mix.

Concentrating Solar Thermal (CST) Technology


... for Solar Heating and Cooling


Soltune is developing a Concentrating Solar Thermal Collector for generation of heat at medium temperatures.

A prototype has been tested with promising results and outperforming its direct competitors. It is a high efficient, small, scalable and low-cost product that targets roof-top and small ground-mounted installations.

The initial target temperature range is between 100ºC and 300°C to supply heat for general heating and cooling and for industrial processes like in food (e.g. dairy), textile, paper or pharmaceutical industries . 

Soltune is currently actively seeking funding for making this product market ready and to commercialize it. If you are interested in being a part of this project, please contact us at info@soltunecpv.com.
