Polysun
Polysun is a versatile simulation program originally developed at SPF. Working in close cooperation with the spin-off company Vela Solaris we make advantage of programme features in the software development field that are concealed to “regular” users.

TRNSYS
TRNSYS is a modular, dynamic building and system simulation program boasting excellent flexibility; if needed the program can be integrated with custom-developed components.

EES
EES is a program for the solution of differential and algebraic equation systems. Its programmable user-interface can be programmed with customer specific applications. (TubeCalc was programmed in EES).

Raytracing
Non-sequential Raytracing enables the enhanment in optical performance of collectors with mirror systems.

FEM
The Finite Element Method can be used wherever complex heat conduction processes may no longer be solved analytically.

CFD
As opposed to FEM, Computational Fluid Dynamics allows material transport processes to be modelled where fluid heat transfer processes are concerned. It is suitable for all flow processes inferred through the simulation fluids and gases.

ALT
Accelerated Lifetime Tests allows prediction on the expected lifetime of new materials to be made, such as with solar absorber layers under preset operating conditions.

The Concise Cycle Test method is a dynamic method developed at SPF to test solar combined systems. The method draws on previous and parallel works of experience from other research institutes [more…].
