Solar panel labels usually show the solar panel’s power rating, certifications and details about the manufacturer.
Solar Panel Labels
High-quality PV modules are characterized by the fact that it can provide a safe operation and high energy production under the given environmental conditions. Their quality standards are usually expressed by – industry-wide – long performance warranties and assessed by a variety of different certifications.
These qualities along with a panel’s output characteristics, certifications and details about the manufacturer are usually printed on the solar panel label on the backside of a PV module.

The example photo of a solar PV label indicates name and address of the manufacturer and the solar module type (blackened).
