Energy generated by your solar panels goes straight to any appliances currently requiring power such as your fridge. Any excess electricity not used in your home is exported back to the grid and you receive a credit on your bill. Your home remains connected to the grid so there is always power available any time of the day or night. Typically solar power system generates most of the power during the day (roughly between 10 am and 4pm).
* If you are consuming more electricity than your solar system is producing, your home will import the extra electricity required from the grid.
Depending on what time of day you are more likely to be using your solar power and the size of your solar power system, this will determine how much you reply on a good buy back price for the solar power you export to the grid. If you will be using most of your power when it is created (during the day) and/or you have a small system (e.g. 2kW) then the rate will not be as important. If you won't be using much of the solar power during the day and/or you have a larger system size (3kW +) then you need to make sure you are with a retailer that offers a good buy back rate.
The solar power buy back rate is the price per unit which energy retailers will pay for you for your excess exported solar power.
