Solar panels receive their ratings under specific testing conditions known as "Standard Testing Conditions" or "STCs". These conditions serve as the industry st...
Panels rarely put out the rated power. They''re typically rated at STC (standard test conditions), and those conditions typically don''t occur in the real world for very long, so on average you get 60 - 80% of the rating. It''s highly dependent on environment, of course. :P Sometimes you can get MORE than the rating (although briefly). :3

Free QuoteThe 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.
Solar panel Wattage 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).
In addition to watt peak, other solar panel ratings include a temperature coefficient, which considers the effect of temperature on the panel's power output, and conversion efficiency, which measures the amount of sunlight converted into electrical energy.
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.
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.
To calculate a more realistic maximum power output rating for any given solar panel, first locate the Nominal Operating Cell Temperature (NOCT) and the Temperature Coefficient of Pmax on the solar panel specification sheet.
