Modules are made with thick, tempered glass very similar to the kind of glass that's used for your vehicle's windshield. Most solar panels have been designed and tested to withstand up to 1” diameter hail (about the size of a golf ball) striking perpendicularly to the module at 50 mph. This means that the hail "hits" the panel at an angle and it bounces off. We've noted that panels have withstood even the larger sized hail that has unfortunately damaged many roofs. Here's a SolarWorld impact test video so you can see how tough modules are.
You will want to replace cracked panels even if they are functioning at full capacity, as cracks may allow water to seep into the panels and create a host of problems. Luckily, most people do not receive panel damage, though their roof may need to be replaced. In these instances, we remove the array and reinstall once the roofer has completed the repairs.
If your array is damaged by hail it is typically covered under your home or building insurance policy. Reach out to your insurance company first, then submit a service request with us and we'll coordinate with you and your roofer.
Removal: Allow 1-2 weeks to schedule the removal of the array so that your roofer can work on your roof. If we can schedule the removal sooner than this time, we absolutely will.
Reinstall: The reinstall will commence two weeks after the completion of your roofer's work. This allows your roof to settle or "bake" first. In our experience, not allowing the roof to bake prior to reinstallation of the array can create roof scarring and severe damage to the roof.
NOTE: The removal generally takes a few hours. The reinstall, however, can take as long as 2-3 days to complete, depending upon the complexity of various factors.
Important: Some people ask their roofer to remove/reinstall their array, but this voids the warranty and it can also cause problems with array functionality, further adding to expenses. You'll want to hire a licensed electrician who also has experience in solar PV to take care of the removal/reinstall to ensure your array is reinstalled according to building and electrical code and is functioning at optimal capacity.
