how is solar energy fed back into the grid ie how does it flow ?

This will explain everything - also has a diagram to show what happenes:

Heres the summary:
* The solar panels are connected in series somewhat like batteries to generate the final system DC voltage
* The solar array's output is routed from the roof to the inverter (normally mounted next to the electric panel)
* The inverter converts the solar array's power from a high voltage DC to a clean 120V AC.
* The 120V AC output of the inverter goes through a dedicated electric meter whose only function is to record all the solar energy kWh that are produced for the entire year.
* The 120V AC continues to flow from the solar meter to a dedicated breaker in your house's electric panel.
* This integrates your solar electricity to both your house and the utility grid.
* When your solar system is providing the exact amount of power that your house is currently using, then your electric meter will stand still.
* When your solar system is providing more power than your house or business is using, then any excess will flow backwards through the utility meter and you will be building a credit with your utility company.
* When your solar system is providing less power than your house is using, then the utility grid will provide the rest; however, your meter will be spinning forward only for the excess electricity that is required.

They sell those in the shops but they're so expensive. And here in the UK we don't get a lot of sun.
