The main reason why this happens is when you have a grid-tied solar system, it has safety measures preinstalled to shut down production in case of a power outage so as not to do extensive damage to the grid or the employees working on fixing the outage.

If you would like to be less dependent on the grid or ideally have no dependence, then you can add storage batteries to your solar system.
Backup batteries store the excess energy produced by solar for later use (for example, when there is a power outage). You can provide backup for some of your home appliances or all of them by installing more batteries depending on your energy consumption.
