Internal damage to solar panels

Can solar panels be damaged?

Solar panels, like any other type of technology, are susceptible to damage over the course of their lifetime. For solar panels to continue to function effectively and for a long time, it is essential to have a solid understanding of how they can be damaged and how to identify any damage that may occur.

What happens if a solar panel is broken?

If an understrength glass is broken, not only the light absorbed by the panel will diminish, foreign elements such as water and dust can go under the glass to shade solar cells and impact energy output. Broken glass makes solar panels more prone to future weather damages.

What are the most common problems with solar panels?

The most common of these is back-sheet failure. While the front glass sheet protects the solar cells from rain, hail, dirt and debris, the white or black plastic back-sheet is designed to protect the rear side of the cells from water, humidity and scuffs.

How do I know if my solar panels are damaged?

Detecting damage to solar panels is crucial for maintaining their efficiency and ensuring the safety of your solar energy system. Visual inspections are a straightforward way to identify issues such as cracks, breakages, or discoloration on the panels.

What happens if a solar panel is burnt?

A burnt bypass diode or connector can leave the panel in open circuit and stop transferring energy outward altogether. A broken junction box with burnt bypass diodes can stop conducting electric current out of the solar panel. WINAICO carefully selects IP67 rated junction boxes that stop dust and water from trickling in to damage the circuits.

Should you replace damaged solar panels?

Deciding whether you are replacing damaged solar panels largely depends on the extent of the damage. Minor issues, such as loose wiring or small cracks, can often be repaired without needing a complete replacement.
