Solar PV (photovoltaic) panels are classified by the amount of power they produce under specific conditions, which becomes their “rating”. The most common ratings used in the solar industry are: 1. Peak/STC: Standard Test Conditions 2. PTC: PVUSA (Photovoltaics for Utility Scale Applications) Test Conditions 3.. .
Peak Sun Hours is one of the most significant factors impacting solar panel performance. While the sun is shining throughout the day, you may think that you’ll get 10-12 hours of solid daylight, but only bout 50% of this is useable for solar. The term ‘Peak Sun Hours’. .
