What does a solar panel rating mean?

Now, let’s explore the meaning of each solar panel rating. The Wattage rating of a solar panel is the most fundamental rating, representing the maximum power output of the solar panel under ideal conditions. You’ll often see it referred to as “Rated Power”, “Maximum Power”, or “Pmax”, and it’s measured in watts or kilowatts peak (kWp).

What is the grading system for solar panels?

The grading system goes A for the best, B for visually defective panels but meet performance benchmarks, C for visually and performatively defective solar panels, and D for broken solar panels. Most manufacturers and distributors only sell grade A and B solar panels, scrapping C solar panels and recycling D solar panels.

What is a maximum power current rating on a solar panel?

The Maximum Power Current, or Imp for short. And the Short Circuit Current, or Isc for short. The Maximum Power Current rating (Imp) on a solar panel indicates the amount of current produced by a solar panel when it’s operating at its maximum power output (Pmax) under ideal conditions.

What is a short circuit current rating on a solar panel?

On the other hand, the Short Circuit Current rating (Isc) on a solar panel, as the name suggests, indicates the amount of current produced by the solar panel when it’s short-circuited. The Isc rating represents the maximum amount of current the solar panel could potentially generate under the Standard Testing Conditions.

How many grades of solar panels are there?

There are four grades of solar panels, but only three of them are usable. Some manufacturers may expand upon this with pluses and minuses to show how individual solar panels rank, but this is rare.
