What really stops PV modules from reaching their 25–30 year design life? Not sudden storms or hail — it’s the daily teamwork of heat, moisture, UV exposure, and material aging.
Core Problem: Protective Layer Failure
However, long-term exposure to high temperatures, high humidity, and strong UV radiation causes critical changes: backsheet becomes brittle and cracks. Once this seal fails, moisture ingress occurs. Water vapor triggers a chain reaction: cell corrosion and oxidation, solder bond failure and interconnect ribbon breakage, internal silver paste electrode damage. These damages cause sharp drop in power output.
Multiple Environmental Stresses Accelerate Damage
Multiple factors stack up:
Meanwhile, modules face combined environmental stresses. Day/night and seasonal temperature swings make internal materials expand and contract. This stress causes cell microcracks and interconnect ribbon breakage, eventually breaking electrical connections.
Heat and UV attack materials directly. High temperatures speed up material breakdown. Strong UV radiation destroys material structure. This makes backsheet brittler and EVA encapsulant yellower, weakening protection.
These factors form a deadly loop. They push PV modules from slow decline to total failure. Therefore, always choose trusted brands like SpolarPV.
