Understanding Solar Panel Specs (NOTC & STC)

The NOCT on your solar panel specifications list is close to the truest power rating that you are likely to see from your solar panel system. Unlike the STC, it uses 800 watts per square meter, instead of the whopping 1,000 watts per square meter. This is the more realistic wattage associated with mostly sunny days and periods of cloud cover.

6 FAQs about [Photovoltaic panels stc and noct]

What is the difference between Noct and STC solar panels?

That’s because, in that 3rd chart, you have a list of specs that were measured at NOCT conditions (key difference is 200 W/m 2 lower sun irradiance; NOCT uses 800 W/m 2 and STC uses 1,000 W/m 2). You can read more about these STC vs NOCT differences here. Clearly, we don’t test solar panels only at STC conditions.

What does STC mean on a solar panel?

STC stands for Standard Test Conditions. All solar panel manufacturers have to measure wattage under these conditions. Example: We can say that a 300-watt solar panel is, in fact, a 300-watt solar panel because it produces 300 watts of electricity under STC 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 STC & Noct?

Purpose: STC allows manufacturers and consumers to have a common reference point for comparing the power output of different solar panels. Definition: NOCT is a set of conditions that represent the temperature conditions under which a solar panel is expected to operate in the real world.

Should I use Noct when designing a solar PV system?

NOCT is useful for comparing two panels, with the same STC rating. A panel with a higher rated power at NOCT for example, will generally result in a higher performing panel. In general you will not need to use NOCT when designing your solar PV system. The NOCT values for voltage, power, and current are typically not used in sizing calculations.

What does Noct mean on a solar panel?

NOCT stands for Nominal Operating Cell Temperature. The reason why we mention these 3 solar abbreviations together is that, on solar panel specs sheets, you can see something like this (for exactly the same solar panel): Solar panel power rating PMax (at STC): 300 Watts. Solar panel rating PMax (at NOCT): 250 Watts.
