Standard Test Conditions (STC) for Solar Panels

The amount of power a solar panel outputs at STC is listed on the panel''s label as its maximum power (Pmax). As expected, this 100 watt solar panel has a Pmax of 100 watts. The result of a test under Standard Testing Conditions is a panel''s maximum power rating, often referred to as its nameplate capacity or nominal power and denoted as Pmax.
