Similar to how solar panels won't operate at peak efficiency during cloudy conditions, they can't produce energy at night when there isn't any sunlight to absorb.
Your panels work hard all day, even through sunset, to ensure you have enough electricity to power your home throughout the day and night. But the photovoltaic (PV) cells in your panels need sunlight to generate that power.
So once the sun goes down, it's time to take advantage of any excess energy that your system produced during the day. This energy is accessible through your home backup power in a solar battery.
