Standard grid-connected (or grid-tied) solar installations are designed to turn themselves off when there is a power outage. The reason for this is we are connecting directly to your home’s electrical panel, which is connected directly to the power lines. If we were feeding power back to those lines while a utility worker was working to fix them, we could put that worker in danger if they thought the line they were working on was dead. Therefore, as a safety feature, the system turns off. There are some ways to get around this, including certain brands of equipment that will allow for a small amount of power to a dedicated outlet for charging of electronics and other small devices. There is also the possibility of setting up a battery back-up, or a generator as a second line of defense. There are always costs and benefits to consider in these type of situations.
