Technical FAQs 4
Why do some solar panels have a high power output rating?
Some panels' high power output rating is due to their larger physical size rather than high efficiency. If two solar panels have 20% efficiency ratings, but one has a power output rating of 350 watts and the other is rated at 400 watts, all that means is that the 400-watt panel is about 14% larger than the 350-watt panel.
What is the wattage rating of a solar panel?
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 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 the efficiency rating of a solar panel?
Most solar panels have an efficiency rating between 17%-23%. A solar panel with a 21% efficiency rating means it converts 21% of the sun’s energy striking it into electricity. Do not confuse the efficiency rating with the rated output. A 23% efficiency rating does not mean the panel will only produce 23% of its rated output in watts.
