Definition and boundaries
Definition
Solar self-consumption is photovoltaic electricity used by loads behind the relevant customer meter instead of being exported to the grid.
Definition claim verification: Verified August 20, 2026
In plain language
Use Solar self-consumption only after the cash-flow perspective, timing, contract structure, included costs, and omitted items are made explicit.
What it is not
It is not total photovoltaic generation, energy independence, or the same percentage as bill savings.
Decision context
Why it matters
Time-resolution, meter boundary, storage charging, load data, curtailment, and tariff treatment determine the measured or modeled amount and its value.
