Abstract: Self-consumption and self-sufficiency of electricity generated from building-mounted or building-integrated photovoltaic (PV) systems have a major impact on the overall profitability of these systems. For this reason, a reliable estimation of both indicators is essential to ensure proper dimensioning and long-term satisfaction of building owners or system operators. However, energy consulting and PV system design regularly fail to consider household specific characteristics and the load variations induced by occupant behavior. The parametric study presented in this paper addresses this deficiency and provides a practical approach to estimate PV selfconsumption and self-sufficiency depending on household type and size.
