Higher self-consumption means less solar energy exported. In a well-insulated home, more generation is exported at the feed-in tariff rate rather than consumed by heating/cooling.

Based on ABCB NatHERS climate zone 59 load limits for a 150m² home. Actual consumption varies by home design, orientation, and occupant behaviour.
