While crystalline panels can last 25 years or more, amorphous panels often have a lifespan of 10 to 15 years. In addition, they are more likely to degrade over time, which can lead to a decrease in their efficiency.
Solar panels are rated for hail impact which is roughly the impact of a 1" hail ball striking the panel at 52 mph. The tempered glass protects the solar cells under this type of impact.
