Fig. 13 charts solar radiation received, domestic hot water demands,
simulated solar power output and solar fraction month-by-month over the 2013.
This new version, as simulated over the trial year 2013, showed energy losses on the main solar circuit (tubing) amounting to 121 kWh and losses via the electric–solar hot water storage tank amounting to 429 kWh.
Annual energy consumption of the solar circuit pump amounts to 64 kWh.
