In plain language

When comparing Photovoltaic temperature coefficient, keep the unit, time period, measurement boundary, and underlying assumptions the same on both sides.

What it is not

It is not ambient temperature and it is not a fixed annual loss percentage.

Decision context

Why it matters

The relevant coefficient, sign, reference condition, module technology, and modeled cell temperature must be identified before applying it to production.
