FAQS about Solar panel performance test standards
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.
What is solar panel performance testing?
Solar panel performance testing occurs in fixed laboratory conditions, known as Standard Test Conditions (STC). Because these conditions are consistent across the industry, you can compare performance metrics (such as power rating, module efficiency, optimal voltage, etc.) between different solar panels.
What are the most common solar panel testing standards & certifications?
Below are some of the most common solar panel testing standards and certifications to look for when comparing solar panels: The IEC is a nonprofit establishing international assessment standards for electronic devices, including photovoltaic (PV) panels.
What are PV module standards & ratings & test conditions?

PV modules adhere to specific standards to ensure safety and reliability. These standards include compliance with industry regulations such as UL 1703 and IEC 61215.
What are the performance PV standards?
The performance PV standards described in this article, namely IEC 61215 (Ed. 2 – 2005) and IEC 61646 (Ed.2 – 2008), set specific test sequences, conditions and requirements for the design qualification of a PV module.
What are the test conditions for PV panels?
The three main elements to the standard test conditions are “cell temperature”, “irradiance”, and “air mass” since it is these three basic conditions which affect a PV panels power output once they are installed.
