Solar domestic hot water system

This article studies some of the statistical properties of domestic hot water (DHW) consumption. To describe the consumptions, we consider three representative statistical properties

This section is intended to study the effect of different solar collector technologies on three performance indicators, namely the solar fraction of the collective hot water

heat collected from the 3 sources (filled area), electricity consumed by the heat pump (dotted area) and theoretical auxiliary energy when the system can’t provide the needs

Forecast and error distribution of the ARMA model for the residence A: on the left, the data (in black), the forecasts of the mean, the PG model and our ARMA model (in blue)
