What do the nameplates on the back of photovoltaic panels mean [PDF]

6 FAQs about [What do the nameplates on the back of photovoltaic panels mean ]

What is a PV backsheet?

A PV backsheet is a special layer that covers the back of a solar panel. Its primary role is to protect the solar cells and internal components, enhancing the panel’s performance and extending its lifespan. Typically, backsheets are made from multiple layers of composite materials, including polymers, fluoropolymers, and polyester.

What is a solar panel spec sheet?

Register Now A solar panel spec sheet provides valuable information about the operating parameters of a panel and can help designers, engineers, and installers determine how to configure a solar PV system.

What does STC stand for on a solar panel?

Standard Test Conditions (STC) The label on the back of the solar panel should state that the figures listed on that label were obtained under Standard Test Conditions, or STC , and it should also tell you what those standard test conditions are. They are generally the same for every solar panel:

What does volt mean on a solar panel?

Open Circuit Voltage (Voc) Open Circuit Voltage (Voc) refers to the voltage output of a solar panel when there is no load connected. By measuring the voltage across the plus and minus leads with a voltmeter, you can determine Voc. This is an important value as it represents the maximum voltage the panel can produce under standard test conditions.

What does E mean on a solar panel?

This is the amount of light reaching the solar panel and is measured in watts per square metre. Under Standard Test Conditions, E = 1000W/m2. This also happens to be approximately the amount of solar radiance received at the earth's surface at sea level.

What does Pmax mean on a solar panel?

Rated Maximum Power (Pmax) This is how many watts the solar panel should be able to put out - under standard test conditions. When you're looking for a 150W solar panel, Pmax is the actual number you're looking for. Voltage Maximum Power (Vmp) This is the voltage that a solar panel will output under standard test conditions of 25°C.
