The power of the sun is gaining in importance as a source of energy the world over. Environmentally friendly solar power systems ensure that we do not need to rely on other sources of energy. The solar market is flourishing. However, competitive pressure in the solar industry worldwide requires manufacturers to seek savings potential while maintaining or improving quality.

Our core expertise for the solar industry

Structure simulation

Structure simulation evaluates the strength, stability and service life of components under mechanical or thermal boundary conditions, allowing precise analysis of stresses, for example, which can then be optimised in a targeted way.

Computational fluid dynamics

Numerical computational fluid dynamics (CFD) calculates phenomena which occur as gases and fluids flow over surfaces. Typical uses in the solar power industry include simulation of the effects of weather on structural elements and components and fluid dynamics calculations for solar collectors.

Multi-body system simulation

Multi-body system simulation is primarily used for rigid body calculation and kinematic simulation of articulated joints and drives of all types, such as servomotors. The calculation speed of multi-body system simulation enables complex modules such as entire assemblies to be easily mapped and integrated into control circuits.


System simulation

System simulation is used to examine highly complex overall systems in which many sub-systems interact. Mapping and simulating such a system is a supreme discipline: the physical properties of all components and sub-systems which are interconnected with each other and exert influence on one another must be described in a mathematically correct way and their behaviour evaluated. It is essential not to lose sight of the overall system as a sum of all parts for all details. TECOSIM has specialised in 1D simulation.


Different mathematical calculation methods enable TECOSIM engineers to identify optimisation potential for a structural component or component group regarding their weight or mechanical properties. Analysis results are incorporated into the development process once or as part of a continuous improvement process. Examples of uses in the solar industry include structural component optimisation, multi-physics problems and stability studies.

Coupled or multi-physics simulation

Sometimes it is simply not sufficient to examine the physical properties of components in isolation. Whenever several physical phenomena are to be examined regarding their interaction with one another, this is referred to as multi-physics simulation. Findings established in this way often present a truer picture than separate studies of individual phenomena. Multi-physics simulations play an increasingly important role in all stages of a product’s life cycle, from the analysis of new material properties, their mapping in virtual material models and parameters, through to production process simulation and calculation of product resistance under the effect of flow. Typical uses in the solar industry include coupled thermal and flow stresses in solar collectors, wind-induced stresses on solar panels or frames and the impact of the casting process on structural component durability.
