Grid Defection
Disconnecting completely from the utility grid and meeting all energy needs with self-owned generation (solar, battery, generator). Currently rare and expensive but declining in cost.
Why It Matters
Full grid defection requires enough storage for multi-day cloudy/winter periods. For most homeowners, staying grid-connected with solar + storage is much more cost-effective.
Related Terms
Off-Grid System
A solar system with battery storage that operates independently from the utility grid, requiring full self-sufficiency.
Microgrid
A localized energy system that can operate connected to the main grid or independently (islanded). Typically includes generation (solar), storage (batteries), and load management.
Energy Independence
The degree to which a household meets its electricity needs from on-site generation and storage rather than grid purchases. 100% energy independence = off-grid capability.
