In plain language
When comparing Photovoltaic specific yield, keep the unit, time period, measurement boundary, and underlying assumptions the same on both sides.
What it is not
It is not system size, module efficiency, or a universal constant for a location.
Decision context
Why it matters
The energy meter boundary, direct- or alternating-current capacity basis, period, outages, curtailment, and weather must match before yields are compared.
