What is PID in solar panels?

PID stands for potential induced degradation. It is an important issue of performance degradation in crystalline silicon solar panels. The degradation could be high as 30% or even up to 70% in some cases. The degradation occurs in solar energy systems and can be reversible or irreversible.

What is potential induced degradation (PID) in solar panels?

Potential Induced Degradation (PID) in solar panels stems from a notable potential difference between the semiconductor material (cell) and other components of the module, such as glass, mounts, or the aluminum frame. This voltage disparity induces current leakage, prompting the migration of negative and positive ions.

How does PID affect a solar cell?

PID impacts the ions of a solar cell and results in the degradation of the output of that cell. PID can significantly reduce the power output of a photovoltaic (PV) module within the first year of operation, with power losses at the module level as high as 70% in the first 18 months.

How do Maysun solar panels prevent PID degradation?

Maysun’s HJT (Heterojunction with Intrinsic Thin layer) solar panels effectively prevent Potential Induced Degradation (PID) through the strategic use of a Transparent Conductive Oxide (TCO) film layer on the glass surface.
