. One of its original applications was to perform dynamic simulation of the behaviour of a solar hot water system for a typical meteorological year so that the long-term cost savings of such a system could be ascertained. It has been used in a plethora of scientific and technical publications for system simulations of various renewable and conventional energy sources.
