Photovoltaic solar panel dents

What are common solar panel defects?

Common defects detected: PID, low output, wiring errors, soiling, and shading issues. Choosing the right solar panels is one of the best ways to avoid common solar panel defects like Potential Induced Degradation (PID), solar panel delamination, and diode failure.

What is solar panel delamination?

Solar panel delamination occurs when the layers within a module start to separate, often between the glass, encapsulant, and backsheet. This defect can allow moisture and air into the panel, leading to corrosion, diode failure, or short circuits. Early signs of delamination include cloudiness, bubbling, or blistering on the panel surface.

Why do solar panels get discolored?

Solar Cells: Photovoltaic (PV) cells are the heart of any panel, converting sunlight into direct current (DC) electricity. Over time, solar cells can crack or become discolored, especially due to UV exposure or heat stress, both leading causes of solar panel defects and power loss.

What is PID & how does it affect a solar panel?

PID occurs when there's a high-voltage potential difference between the photovoltaic cells and the frame, glass, or mounting structure of the panel. This mismatch allows leakage currents to flow, which can degrade the solar cells and cause a drop in energy production.
