You only get that return if you self-consume the electricity. If you put it back into the grid, the return is only the base rate of the electricity itself. With the smaller system you have now, you probably can consume much of it. But if you grow your system, solar's generation profile that's concentrated mid-day and in the summer (periods of relatively low household demand) means that each additional kWh is less likely to be consumed and will generate less value.
