In fact, it will interest you to note that the panels will last much longer even after their warranted power generation life is over. In most cases, the panels are manufactured with a lifespan of between 25-30 years, but they will still work after this time has elapsed. The solar panels wear out very slowly and we have even seen some which continue to produce power even after 20+ years. With regards to fragility, unless the panels sustain a direct hit form a large falling limb, they aren’t as fragile as many people perceive them to be. Small stones or items such as hail, bits of debris, rain and others blown by wind shouldn’t have any significant effect on them.
