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.
