Will my insurance company know about the panel upgrade?

Do I need to be home during the panel upgrade?
We recommend you or a trusted adult be on-site for the duration of the panel upgrade. Power to your home will be off for several hours during the work. We give you an exact time window so you can plan accordingly.
