What is the difference between the solar panel current classification l and m

What are the different types of solar panel ratings?

There are essentially two classes of solar panel ratings. There are ratings based on tests performed in a laboratory under tightly controlled settings and there are ratings that more closely reflect real world conditions. A solar panel is initially tested in a factory under controlled settings.

Do solar panels have a current rating?

Solar panels come with two Current (or Amperage) ratings that are measured in Amps: The Maximum Power Current, or Imp for short. And the Short Circuit Current, or Isc for short.

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.

What is the peak rating of a solar system?

If you add up the rated power for all of the panels, then you get the peak rating of a solar system. The STC rating is always the highest rating. This is because it rates solar panels in terms of the instantaneous power that they produce under a set of ideal conditions. But when do ideal conditions ever exist in anything in this world?
