Abstract : This study presents a parametric sensitivity analysis of the dynamic simulation of the Solar Domestic Hot Water (SDHW) and Photovoltaic (PV) solar systems in an energy positive house. The optimized parameters concern the solar collectors, the storage tank and the fluid circulator. Significant gains are obtained on most of the parameters which allows for a better solar fraction with the SDHW. The energy need for the DHW auxiliary and pump is divided by three with a load scenario corresponding to a family of four. Moreover, we extended the study to the PV system to provides the best repartition option between thermal and PV panels on the solar roof. This maximizes the opportunity of generating surplus electricity, sold back to the power grid.
