In the “Energy” section the efficiencies are calculated. Any efficiency ratio always has the same principle for calculation. The efficiency is the useful outgoing energy (or power) divided by the ingoing energy (or power). The production efficiency, system efficiency and PER (Primary Energy Ratio) are visualised in the figure below. The yellow arrows represent the primary energy, the red arrows the useful thermal energy, the purple arrow the electricity and the grey arrows the thermal losses.
