Your Energy Bill
Once you get your energy bill, try to look for the graph (representing your energy usage chart / graph). This way you may yourself judge your energy utilization. Once you have this thing clear, accordingly you may opt for the size that you need.

Many researches mention that the best is to use the direct energy supply.
Selecting the Right System
If the percentage utilization of electricity is 33% during the day time, the right size of the solar system will be of 2kW. This will be the best choice as it will generate only the amount of energy that is needed and cause no wastage in between as there has to be no transferring of energy to the grid.
A size bigger than the mentioned above may not be the right investment if there is none who stays at home during day time. If you stay at home (working from home / retired) then it is the right choice for you.
