Proper labeling of solar parks is not merely a formality, but an essential part of the overall safety and operation of the system. Clear and durable markings help ensure that installers, maintenance technicians, and first responders can quickly and correctly understand the system. In addition, compliant labeling is a prerequisite for successful inspections and helps prevent dangerous situations.
Solar parks include both DC and AC systems, and these may remain energized even when the equipment appears to be switched off. Therefore, all critical information must be clearly marked and easy to read.
Why is labeling important?
- ensures the safety of workers and first responders
- helps prevent incorrect connections and disconnections
- simplifies maintenance and fault detection
- supports compliance and inspections
Which standards should labeling comply with?
Solar park labeling should follow international IEC standards, which define what information must be displayed and how durable the labeling must be.
The most important standards are:
- IEC 62548 – installation requirements for photovoltaic systems
- IEC 61730 – solar panel safety and label durability
- IEC 62109 – safety of inverters and electrical equipment
These standards define, for example:
- which warning labels must be visible
- what technical information must be marked
- how durable the label must be (UV, temperature, wear resistance)
Where should labeling be used in a solar park?
Labeling must cover the entire system, not just individual devices. In practice, this means that all important components must be clearly identified to avoid confusion and speed up work processes.
Typical labeling locations include solar panels, combiner and distribution boxes, inverters, and cables. Circuit breakers and disconnect points must also be marked, as these areas present the highest safety risks.
Main labeling areas:
- solar panels and their classification
- combiner and distribution boxes
- inverters and circuit breakers
- cables and connections
Portable label printers – flexible on-site labeling
Portable printers are increasingly used for creating labels directly on-site. This provides flexibility for immediate changes and reduces the need for pre-printed labels.
Portable printers are especially useful during installation and maintenance work, where systems may change over time and labeling needs to keep up.
