Day and Night
During the morning, the whole house is awake and using power. Your solar array is also producing enough energy to assist in powering your home. Your solar array generates DC electricity, which is converted to AC electricity by your inverter and sent to your home's appliances.
During the morning, you save money with solar by directly using free and efficient energy from the sun. Your appliances and morning routine are powered directly from the sun, saving you anywhere from 24c/kWh to 28c/kWh.
During the middle of the day, the solar array achieves its maximum output. Your solar array sends DC power to your inverter which converts the electricity to AC, before deciding where to send it. Given most families are out to work or school, most of your power is sent to the Grid or used to charge your DC home battery for later use.
By sending power to the Grid, you are eligible for a FiT or Feed-In Tariff. You will receive between 8-16c for every kilowatt-hour you export. Alternatively, you can charge your DC battery, which will provide you with cost-efficient power during the evening.
During the evening, your solar system ramps down, however, for many homes this is one of the busiest times for power consumption. Thankfully, your battery system can provide DC power to your inverter, which is converted to usable AC electricity and sent to your appliances.
By consuming battery-provided power during the evening, your home can reduce its reliance on grid electricity, saving between 24c/kWh-28c/kWh. Many home batteries can provide power for hours on end, helping your family through the night.
