6 FAQs about [Photovoltaic panel STC parameter query]

What is STC test for solar panels?

The STC test for solar panels involves subjecting the panels to specific conditions, such as a solar irradiance of 1,000 watts per square meter, a cell temperature of 25°C, and an air mass of 1.5. These standardized conditions allow for accurate measurement and comparison of module performance. What is STC efficiency?

Why do solar panels need STC ratings?

Cell temperature and its management play a vital role in solar module efficiency, and understanding STC ratings empowers informed decision-making for optimal system performance. Standard Test Conditions (STC) are a set of industry-defined parameters used to evaluate the performance of solar panels under consistent test conditions.

What does STC mean for solar panels?

What is a standard test condition for a photovoltaic solar panel?

The standard test conditions, or STC of a photovoltaic solar panel is used by a manufacturer as a way to define the electrical performance and characteristics of their photovoltaic panels and modules. We know that photovoltaic (PV) panels and modules are semiconductor devices that generate an electrical output when exposed directly to sunlight.

How much power does a solar panel produce under STC?

When a panel is advertised as having a capacity of 350Wp for example, this is the power it is expected to produce under STC. Since all manufacturers follow this same standard, it gives a fair basis to compare them against each other. The conditions (from IEC 61538): Note that the temperature rating is for the cell within the panel.
