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
