Pingel and others published potential induced degradation of solar cells and panels ieee photovoltaic specialists conference honolulu find read and cite all the. Reliability was ensured by protecting the cells with a quartz or sapphire cover sheet from energetic particles outside the atmosphere and by using np type cells on 6. Pdf on jan 1 2010 s. Solar projects has raised the threat level of potential induced degradation pid of solar panels.

Solar panels depending on the leakage current between solar cells and ground has been first addressed by nrel in 2005 1. This potential degradation mechanism is not monitored by the typical pv tests listed in iec 61215 2. The first satellites such as vanguard i required only moderate power and the weight of the solar panels was low. Potential induced degradation as the name implies can occur when the module s voltage potential and leakage current drive ion mobility within the module between the semiconductor material and other elements of the module e g.

The increased usage of transformerless inverters on u s. Potential induced degradation as the designation implies occurs when the module s voltage potential and leakage current drive ion mobility within the module between the semiconductor material and other elements of the module e g. This paper is focusing on potential induced degradation pid of wafer based standard p type. Pid happens when different components in the same system are at different voltage potentials such as the frame and the solar cell which can allow electrical current to leak and modules to.

Standard accelerated testing shows that they are almost impervious to the dominant failure. Glass mount and frame as shown in figure 1 thus causing the module s power output capacity to degrade. Potential induced degradation pid is a phenomenon which affects some pv modules with crystalline si cells and leads to gradual deterioration of performance reaching up to 30 percent and more after a few years.
