6 FAQs about [Solar inverter stc]

What does STC mean for solar panels?

In solar panel specification sheets, you will see specs measured at STC. These are the Standard Test Conditions we measure all solar panels in the lab. In some cases, you also have NOCT or NMOT specs listed. Here we will explain exactly what STC means for solar panels. Alright, let’s start at the start:

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.

What is the difference between STC and Noct in solar panels?

You might see them under the solar panel specifications sheet and wonder what to make out of them. STC and PTC are both test conditions used to rate the performance of a photovoltaic module (PV panel), while NOCT is referred to the PV cell temperature and it’s obtained under prefixed environmental conditions.

What are standard test conditions (STC) for solar panels?

When solar panel producers have to tell how much electricity a solar panel produces, they have to use the same set of conditions to measure the wattage, voltage, amps, and so on. The agreed test conditions all manufacturers have to adhere to are called Standard Test Conditions (STC) and are as follows: Irradiance: 1000 W/m2.

What is a STC & how does it work?

The STC was developed to allow for easy measurement and comparison between solar panels, as it does not involve external factors that might impact the energy output. The standard test conditions for solar testing have a strict procedure that involves panel orientation directly to a solar source of 1,000W per square meter.

What is the difference between PTC and STC?

PTC is generally considered as a more realistic measure of PV output because the test conditions better reflect “real-world” solar and climatic conditions, compared to the STC rating. To give you an idea of the PV panel performance under these two different tests, I selected to random tests from The Go Solar California database.
