Where you are if it’sHow much kw/hours will a 4 kw system generate in a year ?
Where you are if it’s
Direct south with 30° pitch 930 hours of sun
SE 881
SW 881
Times these hours by system size 881x4=
3,524kWh annually
Think mine have averaged 3900kwh a yearHow much kw/hours will a 4 kw system generate in a year ?
Yeah it’s the official MCS sunshine hours. People can get up to 10/15% more but that’s the slap on the back you get from customer when it DOES produce more. Everyone is happy.I believe this is the official figure you have to quote when selling, am I right?
My own experience is we are getting much better than this. It may be different in 20 years time though.
You will have a bill as your exporting at 4p and importing at 14So if I install a 4 kw system and use say 2000 units per year does that mean I won't have to pay an electric bill?
Yes as long as you have timers on the main usersWhat could you run off a 4kw system? A small family home?
Do I have to import? Can't I use what I generate?You will have a bill as your exporting at 4p and importing at 14
