Can I install a larger system then my distributor allows?

A lot of the electrical distributers now have a limited size solar system that they allow to be connected to the grid, If this is not the case they will offer a limit to the amount of power that they allow you to feed back into the grid (export limitation). This may mean that even though the distributor may offer a Zero or negligible export limitation, you are still allowed to install a solar system. The annoyance of this is that you will need to spend a little bit more and put in a Zero export device that has the functionality that allows it to monitor your usage. The power from your roof will still get used in your property but depending on how much extra is to be exported you may or may not be allowed to feed this power to the grid and your solar system will ramp down to match your consumption.
