Water Drops Inside the Solar Photovoltaic Panel Causes Impacts and Solutions

Why Water Drops Form in Solar Panels - The Silent Efficiency Killer

Have you ever noticed mysterious water drops inside the solar photovoltaic panel during morning inspections? This common yet overlooked phenomenon can reduce energy output by 15-30% according to 2023 field studies. Let's explore why moisture becomes trapped and how it silently sabotages your solar investment.

The Science Behind Condensation in PV Modules

Solar panels aren't waterproof aquariums - they breathe! Temperature fluctuations create ideal conditions for condensation through:

• Thermal cycling (day-night temperature swings)
• Imperfect sealant degradation over time
• Microscopic gaps in EVA encapsulation
