A very good tool that
helps to visualise the service technicians important interdependencies in regard
to the possibilities to save energy and to reduce the CO2 emission through the
use of solar energy technology, are computer simulation programmes like "F-Chart".
Comparable computer simulation programmes are also used in the collector, storage,
and control and regulation technology (s. corresponding chapters).
Diagram 7 was e.g. created with such a simulation programme and shows the "average monthly solar coverage rate" of a solar energy installation used for water heating purposes in Germany over a one year observation period. The "solar coverage rate" indicates that in the summer months June and July the complete water heating for an average household in Germany can be done with a solar energy installation. During the winter months however, substantial additional heating must be done using other energy sources. Diagram 8 shows the energy savings and emission reductions which can be achieved with a solar energy installation for water heating purposes in Germany.
