Limitations of IEC 61701

IEC 61701 is a standard that provides a procedure for testing the endurance of photovoltaic (PV) modules against salt mist corrosion, which is a common environmental stress that PV modules face, especially in coastal areas. However, IEC 61701 has some limitations that must be taken into account when using the standard.

Firstly, testing the corrosion resistance of PV modules in a salt mist chamber only provides an approximation of the actual corrosion that can occur in real-world conditions. Salt mist corrosion is affected by a variety of factors such as the intensity and duration of salt spray, temperatures, humidity levels, and the types of pollutants in the air, which cannot be fully simulated in a laboratory setting. Thus, it is important to note that the results obtained from IEC 61701 tests might not fully reflect the PV module’s actual long-term durability in the field.

Secondly, IEC 61701 only evaluates the salt mist corrosion resistance of the PV module itself and does not consider the entire PV system as a whole. For instance, other components of the PV system such as mounting structures, cables, connectors, and inverters might also be subject to salt mist corrosion and affect the overall performance of the system. Therefore, it is essential to select all components of the PV system carefully based on their individual resistance to salt mist corrosion.

Lastly, IEC 61701 is not a pass-fail test but rather a performance-based test, meaning that the PV module is tested for a specified period, and the performance degradation is evaluated against the minimum threshold specified in the standard. This means that even if a module performs better than expected, it still must have undergone the testing period to comply with the standard. Conversely, a module that does not pass the minimum requirement still has residual value.

Overall, IEC 61701 is a useful standard for evaluating the corrosion resistance of PV modules against salt mist corrosion. However, the limitations such as laboratory testing conditions, sole PV module testing, and performance-based testing, must be considered when deciding between different PV modules and selecting the entire PV system.
