Irradiance, Cell Temperature, Special Distribution and Module Area
PV Standard Test Conditions (STC)
High Reliability and performance of solar panels are crucial for PV plant owners and private solar panel owners. In order to monitor both aspects, the photovoltaic industry relies on standardized testing conditions, known as STC (Standard Test Conditions) and NOCT (Normal Operating Cell Temperature. By using a set of standard parameters for evaluating the performance of PV Modules, manufacturers and researchers are able to compare the performance of solar panels.

PV STC parameters
Irradiance, Cell Temperature, Special Distribution and Module Area
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).
