Vela Solaris is a Spin-Off of the SPF Institut für Solartechnik, Rapperswil.

Our main goal is the distribution and further development of Polysun. Maintenance and technical extension of the Software is key for a long term success in providing a tool for the simulation of solar thermal systems.

In close collaboration with SPF, Vela Solaris is continuously engaged in research in the area of solar simulation. Projects are typically, but not exclusively, accomplished in close collaboration with SPF. Please contact us if you look for a software partner in a research project!
