Understanding Solar Photovoltaic (PV) Power Generation

In these cases, the strings of solar panels are connected directly to the inverter. PV Inverters. An inverter is a device that receives DC power and converts it to AC power. PV inverters serve three basic functions: they convert DC power from the PV panels to AC power, they ensure that the AC frequency produced remains at 60 cycles per second

Technical Information

During operation the PV modules are connected to the AC grid via the inverter. Thus, depending on the device type, a portion of the alternating voltage amplitude arrives at the PV module. As a result, the complete PV array oscillates with an alternating voltage in relation to its environment. At this point, two cases must be distinguished:

Causes and Solutions of the Potential Induced Degradation (PID) Effect

Example of voltage distribution in the string connected to a transformerless inverter at 1000V DC system. The PV module that falls in the more negative section of the string will be the most affected by this effect because its cells would be polarized at around -500V while the frame of the module is at 0 potential (because it is grounded).
