The amount of power your solar energy system can generate is dependent on sunlight. As a result, your solar panels will produce slightly less energy when the weather is cloudy, and of course, none when the sun is down. However, thanks to Net Metering, your system will send any excess energy it creates back to the electric grid in exchange for a credit, which you can redeem when you aren’t producing energy, like during the night or when your panels are covered in snow or ice. This whole process saves you money by reducing your energy bills.
