When the sun shines, the solar panels on your roof turn this sunlight into DC electricity. Your solar panels will start generating power as soon as the early morning sun hits them and continue all day until the last ray of sun disappears in the late afternoon.
The Inverter then transforms the DC electricity produced by the panels into 240V AC electricity, the same sort of electricity as what you get from the grid to power your home.
The electricity from the inverter is fed into your switchboard where it is distributed to all your appliances in your home.
Excess electricity that is not used is fed back into the grid for everyone else to use and you will be paid a Government feed in tariff from your electricity retailer and they will credit your bill for the electricity you supply.
