Modern solar panels for homes don't suffer from these early solar panel problems
. They are built to be more durable and have solar cell formulations that will last for decades without losing their ability to generate power. The only problems that plague these newer panels are damage from the weight of snow in colder climates and the threat of being blown off the roof in areas with high winds. Both of these problems can be addressed through the proper mounting of your solar panels, which will minimize the chances of damage from these types of hazards. As long as they are mounted securely, your solar panel system should give you decades of use with little need for attention.
