The following key parameters define the PV Standard Testing Conditions:
- Irradiance: The solar panel is exposed to 1000 W/m² of simulated solar irradiance (the amount of sunlight received at the Earth’s surface on a clear day under specific conditions).
- Cell Temperature: The cell temperature under STC is set at 25 degrees Celsius (77 degrees Fahrenheit).
- Spectral Distribution: The spectral distribution of sunlight is set to air mass 1.5 (AM 1.5), which represents the average path length of sunlight through the Earth’s atmosphere at a specific angle.
- Module Area: The area used for calculating the panel’s performance is typically one square meter (1 m²).
