What happens at night, or when the weather turns cloudy?
Since the amount of power your solar system generates is a direct result of sunlight, it will produce slightly less energy when the weather is cloudy. Your system will not produce any energy at night. Your SolarCity power system will be interconnected to your locally utility grid, so that you can automatically begin to draw power from the grid whenever you need it. You won’t experience any power interruptions—the switch between solar system power and the utility grid happens seamlessly, with no effort on your part.
