    Hi. 
    System is

    Ja 330w black panels x 12
    Growatt 3.6kw inverter
    Solo 2 monitor. 

    This is a quote from your first post.  If this is what you were told you would get then you can see that 12 x 330 W is not quite 4 kW and the inverter limits your maximum output to 3.6 kW.  The problem is that this does not seem to have been properly explained to you.

    I am saying that a 4kw system would be installed and that is what I should have got, regardless of the output.

    If It gives me 4kw output at some point then I would be happy.

    There was no mention that it was only going to be a 3.6 kw system.

    Exactly mate, it was never explained to me. 

    I was told it was a 4kw system that would be installed nothing less.

    If the installer had said that it would be less than 4kw, then i had an option of saying yes or no, but that was taken away from me.

    If you were told in advance that you would get a 3.6 kW inverter then that is exactly where it is mentioned.  The problem is that you did not know to interpret that to mean that your output would be limited to 3.6 kW.

    The problem is a lack of knowledge that not explained to the customer. I'm looking at PV at the moment and have researched the area thoroughly maybe OTT so I would say I'm not your average customer. To make PV more mainstream you shouldn't have to do loads of research and thing should be explained a bit better.

    Basically to be able to compare panels they need to set a standard unfortunately for you its not based on August in Glasgow. If they were your panels maybe 290w not 330w.

    Another thing that isn't explained to people is with inverters bigger is not better and inverters should be less than the panels as this makes them more efficient .

    The number you should be concentrating on is the estimated annual output which will be on your quote. Again it not guaranteed as its weather dependent . 
    8kw system spread over 6 roofs , surrounded by trees and in a valley.

    This is on the MCS Certificate

    Total Installed Capacity (kW): 3.96
    Estimated Annual Generation (kWh): 3210.0

    So

    Estimated Annual Generation (kWh): 3210.0

    that's the number that should reasonably expect so don't get hung up on the 4kw thing, most people do end up generating more than the estimate though, maybe people with PV on this board could comment on that.

    Also you do usually get the sale BS like any other produce like the 50% reduction in your bill. Again this is only from research, without batteries you will be doing well to use 50% of the generated electric. So in this case say 1600KWh with the other 1600KWh being exported @5p ish . Again anyone with real life experience it would be good to hear your input.
