For the uninitiated, one of the most common questions about solar power is “what happens at night?”.
If the sun isn’t out, your solar panels won’t work, so do you just not have power at night if you go solar? Of course not!
When you have solar power, you’re still connected to the grid. The solar system works in conjunction with the grid.
During the day, your solar system makes more than what your house needs to function at that time. The excess goes back onto the grid and your meter keeps track of the extra going onto the grid.
At night, when your solar isn’t producing any power, any energy you need comes from the utility grid. The meter then measures how much power is coming into your home.
If your solar system is sized correctly, the power going out to the grid will cancel out the power coming into your house from the grid. In essence, you’re using the utility as your solar system’s battery.
If you are thinking about going solar, don’t worry… you don’t have to live by candle light and wood heat at night!
