In plain language
For Non-export photovoltaic system, the controlling utility tariff, interconnection document, meter arrangement, and jurisdiction matter more than a generic national description.
What it is not
It is not an off-grid system and it does not mean the property never imports grid electricity.
Decision context
Why it matters
Controls, response time, metering point, storage, load variability, fail-safe behavior, testing, and utility requirements determine the exact non-export design.
Applicable jurisdiction: US; program and utility rules vary
