In plain language
For Photovoltaic export limit, the controlling utility tariff, interconnection document, meter arrangement, and jurisdiction matter more than a generic national description.
What it is not
It is not necessarily a limit on photovoltaic generation or household self-consumption.
Decision context
Why it matters
The limit can be equipment-based, control-based, tariff-based, time-varying, or measured at a specified point; production, load, storage, and enforcement behavior must be modeled separately.
