Potential Induced Degradation (PID) is a phenomenon which affects some PV modules with crystalline Si cells and leads to gradual deterioration of performance. The degradation can be as much as 30% or more after a few years. Some module manufacturers are already working to develop countermeasures by using new materials, but the general trend to three-phase systems and system voltages more than 1,000 VDC is currently exacerbating the problem rather than alleviating it. In addition to negative earthing of the PV array, Solis now offers a simple technical solution to prevent this reduction in power of PV modules. This Solis Seminar first gives a brief overview of the PID effect and then explains how the Solis built-in PID Recovery module works and when it can be used.

On June 4, 2021 at SNEC 2021, Shanghai, China, Huawei’s smart string energy storage system (ESS) for residential use, the LUNA2000, received 2PfG 2511 and VDE-AR-E 2510-50 certificates from TÜV Rheinland, a Germany-based testing and certification service provider.

Distribution faults can damage equipment, reduce reliability, and adversely affect a utility’s bottom line. Some existing fault-management strategies can even cause more damage by multiplying the energy applied to a system when testing a line for faults after an event. Better switching and protection techniques are available to increase customer reliability and reduce the impact of persistent outages on customers.
