What are the most common problems in photovoltaic systems?

Below, SolarLab lists the most common problems that can occur in photovoltaic systems and how to solve them: 1. Improper installation Installer errors are the first most costly problem and the second most common. This only shows that most investors save money on contractors entirely unnecessarily.

What causes a solar panel to lose power over time?

It’s not unusual for a solar panel system to see gradually reduced output over time. Panel degradation - a natural and unavoidable process - is often the culprit and is factored into the system's performance warranty.

Why are my solar panels underperforming?

If your solar panels are underperforming, it's possible that the problem originated when the panels were being manufactured. Solar panels may be chipped or cracked in production, often signifying that the manufacturer did not use premium materials.

Why do solar panels fail?

Blown bypass diodes - Permanent failure often due to severe localised shading or overheating. Earth leakage is a common problem with older solar panels that is often caused by backsheet failure leading to water ingress or PID or potential induced degradation. Strings of solar panels operate at high voltages, up to 600V or higher.

What are common solar panel problems?

In conclusion, being aware of common solar panel problems such as dust accumulation, shading, and microcracks can help system owners take timely action. Regular maintenance, professional inspections, and addressing potential defects will maximize solar panel efficiency. For more informative solar content, keep reading our blogs.

What happens if solar panels run at high voltages?

Strings of solar panels operate at high voltages, up to 600V or higher. Operating at these elevated voltages over many years can, in some cases, allow a current leak to develop through the cells to the aluminium frames of the solar panels and into the earth, resulting in a significant performance loss.
