What to do if the photovoltaic panel base film ages

How often should solar panels be cleaned?

This means greater safety and a longer useful life for your modules. How often is cleaning solar panels necessary? For residential systems, a visual inspection is recommended every 6 months and a washing of the solar panels at least once a year. In particularly dusty areas or near the sea, washing solar panels should be more frequent.

How to clean solar panels?

Cleaning solar panels can be done independently, but with proper precautions: 1. Use only pure water Recommended water type: Prefer demineralized or distilled water. Why avoid other types: Tap water contains mineral salts that can leave streaks or limescale deposits, compromising glass transparency and thus solar absorption.

Why is Eva important for photovoltaic encapsulation film?

As the main material of photovoltaic encapsulation film, EVA is of great significance to photovoltaic modules. Once aged, it will not only affect the performance of photovoltaic modules, but also cause fading, delamination and blistering of photovoltaic modules. 1. Fading

What happens if a photovoltaic module is exposed to sunlight?

Fading During the operation of photovoltaic modules, EVA will undergo “yellowing” and “browning” when exposed to the outdoor environment for a long time. The discoloration reduces the light transmittance of EVA, reduces the photocurrent of the photovoltaic cell, and finally leads to the power loss of the photovoltaic module.
