What are some examples of good Solar Panel Labeling Practices?

As the solar industry continues to grow and become a more common source of power across the globe, labeling is more important than ever. To ensure transparency, the labeling of solar panels should provide consumers with the information they need to know in order to make an informed decision. In this article, we discuss the best practices of labeling along with examples of what this might consist of.

Standardized formatting

To maintain a form of consistency across the industry, adopting standardized solar panel label formats makes it simpler for consumers to compare their options and find the information they need. The International Electrotechnical Commission (IEC) has developed a standard label format to promote transparency in the industry, creating an example layout which considers the needs of both manufacturers, supply chains, and consumers.

Maintenance guidelines

Labels should include basic guidance regarding cleaning the solar panels and inspecting them for damage, helping consumers prolong the lifespan of their solar panels and optimize energy output. Although a full guide will not be possible on the labels, providing an overview of maintenance information will ensure consumers are provided with the facts they need to make an informed purchase.

QR codes

Solar panel labeling should consist of clear and comprehensive information which provides all the necessary details that consumers need without overcrowding the space. In addition to key information such as capacity, warranty, and certification, it is a good practice to include a QR code which directs the consumer to more in depth information. When scanned, users will be redirected to a website which they can search if they want more detail about the product. such as any technical specifications, installation guides, and troubleshooting information.


Whether this be for the visually impaired or those who speak another language to the primary language printed on the solar panel labels, the information should be accessible to a wide range of consumers. To ensure that consumers from diverse backgrounds can interpret the information, labels are often printed in multiple languages. Another good practice is to save space by using universally recognized symbols and icons to convey key pieces of information.

Certification marks

Examples of widely recognized certification marks include the UL certification, the IEC certification, and the TÜV Rheinland certification. Certification marks from recognized organizations should be displayed prominently to assure consumers that the panels meet industry standards and have undergone rigorous testing.

Real-time monitoring

Nowadays, solar panels are becoming more advanced and many provide real-time monitoring capabilities. These allow consumers to make informed decisions about their energy usage and maintenance through the real-time data on energy production and system health. To educate consumers on the capabilities of these systems and remain competitive, the labels should provide instruction on how consumers can access these systems.


Solar panel labels should provide information about the environmental impact of the panels so consumers can make a decision that aligns with their ethics and goals. An example of this would be providing estimated values of the carbon footprint over its lifetime or comparisons to other forms of power, providing insight into the impact that is expected upon implementation of the solar panels.
