Solar glass itself is actually quite stable in outdoor environments. Once installed in modules, it can handle rain, heat, and humidity for many years without problems.
But before lamination, during storage and waiting time, moisture-related issues sometimes appear. Not always serious, but often noticed only when the crate is opened.
1. Condensation caused by temperature difference
This is probably the most common situation.
Day and night temperature changes, or a container arriving from sea freight into a different climate, can easily create condensation inside the packaging.
Sometimes you open a wooden crate and find slight moisture on the glass surface or packing paper. It doesn't happen every time, but when it does, it is quite visible.
2. Long storage without opening
In some warehouses, solar glass is not used immediately and stays sealed for days or even weeks.
When the crate remains closed, air inside doesn't circulate. Over time, humidity slowly builds up inside the package.
From the outside everything looks normal, but inside it can feel slightly damp when opened.
The longer it stays, the more noticeable it becomes.
3. Warehouse floor conditions
This is something often ignored in daily handling.
If glass crates are placed directly on concrete floors, especially in humid conditions or after rain, moisture can slowly come from the bottom.
It's not an instant problem. It develops quietly over time.
By the time it is noticed, the storage period has usually already been quite long.
4. Regions with strong weather changes
In some locations, temperature and humidity change quite a lot between day and night.
Warm during the day, cooler at night, then back again. This cycle can easily create condensation inside packaging materials.
The glass itself does not move, but the environment around it keeps changing.
5. Wooden packaging absorbing moisture
Wooden crates are not completely stable in humidity.
When the air is moist, the wood absorbs it slowly and may slightly change in shape or rigidity.
Usually it is not dramatic, but over time it can affect the overall condition of the package.
6. What actually happens in practice
Most moisture-related situations are not real "defects" in solar glass.
They are more like a combination of storage time, temperature changes, and environmental conditions.
Many times, people only notice it when the crate is opened, but the process has already been happening quietly for a while.
