A second important requirement for a high self-sufficiency quota and a high self-consumption quota is an appropriate load profile: The distribution schedule of the PV power is defined in quite narrow limits by the alignment of the PV array and the weather.
Self-consumption, as defined above, is normalized by the total power generation, and self-sufficiency by the total power demand. Therefore, increasing the PV generation relative to the demand will always decrease the self-consumption while self-sufficiency will be increased or remain unchanged, cf. Fig. 2. The converse holds for a relative ...
Researchers have also evaluated the performance of household rooftop PV-battery systems by analyzing and optimizing PV self-sufficiency (the degree of PV generation sufficient to fill energy needs) and self-consumption (the portion of PV generation that is directly consumed) [30], [31], [32]. Yet few studies have quantified the PV potentials ...

generated from PV systems. The same applies to self-sufficiency, i.e. the share of a household''s annual electricity consumption that can be covered by the power generated from a PV system. Among others, Frank et al. (2015) outline that the monthly energy balance of power generated from PV panels and electrical power
Higher PV shares, particularly in distribution grids, necessitate the development of new ways to inject power into the grid and to manage generation from solar PV systems.
