Will my electricity work during a power outage?
Solar panels, by themselves, will not work in a power outage because they are grid tied. This means your solar system is wired into your electric company's grid, giving you the ability to take advantage of net metering. When the power goes out from your electric company due to a natural disaster, routine maintenance, or due to an overload, your panels will also stop producing energy form the sun. This is for safety reasons when the electric company sends utility workers to fix the lines. But, when you add a solar battery backup to your solar PV system, your lights stay on even when your neighbors are down.
