6 FAQs about [Causes of Photovoltaic Panel Discoloration]

What causes solar panel discoloration?

However, in the realm of solar panels, this discoloration is a deeper phenomenon with potential consequences. Solar panel discoloration is a physical change in the panel’s color due to environmental factors or material degradation, especially the yellowing or browning of their once clear and shiny surfaces.

What causes PV module discoloration?

PV module discoloration can be caused by various factors, including: Exposure to UV Radiation: Over time, prolonged exposure to sunlight can cause degradation of the materials used in solar panels, leading to discoloration. This degradation can affect the appearance of the panels and reduce their efficiency.

What are the solutions to solar panel discoloration?

Why should solar power professionals know about common solar panel problems?

Thus, solar power professionals need to be knowledgeable about common solar panel problems to better service solar clients and prevent underperforming solar assets. Regular maintenance and performance modeling can help prevent revenue loss for solar system owners through early detection and corrective action.

Why is my solar panel turning yellow?

In instances of severe discoloration (for example, turning deeply yellow or brown), it is possible that discoloration might be hinting at bigger overall problems rather than just surface coloration. In such cases, the discoloration may indicate a reduced lifespan for the solar panel.

How does discoloration affect the performance of PV panels?

Discoloration can affect the performance of PV panels by 10–14%, delamination can reduce the maximum power by more than 15%, and corrosion can reduce the performance of PV modules by up to 30%.
