How many kWh's does your solar panel generate per year?
I'm looking at getting some photo-voltaic solar panels for my house (U.K.) If you have had them for a while, can you tell me how many kWh's per year you generate, your panel's rated maximum output (Watts) and your total panel area please? I want to get a realistic estimate for my property. It's all very well looking at the data sheets produced by the companies that sell them but I want some idea of what people are actually getting. Thanks.

The electricity generated depends on the solar panel capacity, that you are using. Install the panels in the direction facing direct sun rays. The number of peak sunlight hours varies across the UK, but taking average, it is about 7 hours at the height of summer, and about 2 hours in the winter. The average UK household uses 3-4000 kWh of electrical energy/yr. A 2 kW solar installation will produce around 1700 kWh of energy. You can checkout http://mysolarzone.com/ for any query related to solar energy system.

You'll have to get the data for your specific location & installation - here in Germany, the number varies between 1200 kWh/kW_peak and 900 kWh/kW_peak per year (for optimum orientation and inclination). My own setup (and those of the people I've been talking to) fit well within the specific pre-installation estimates (if you want to see what such an estimate may look like, check e.g. here http://www.solaranlagen-portal.com/photovoltaik-re... - there are a lot of those PV calculator pages over here).
OK, just on whim, I entered 'pv calculator uk' into google. Plenty of apparently useful results.

£3.51 kWatt installation with 18 panels, on the south coast near Worthing, south-east facing. There is no maximum output as such, we have seen 3.84 kWatt on a brilliantly clear day, and 28.4 kWatthrs on our best day.The first years total was 3494 kWatthrs.

We get around 2800kWh pa with a 4kW panel array
Its difficult to give you an answer without taking into account:
1 Where you are in the UK
2. Which way your roof faces
3. Angle of roof / shade.
There is an independent calculator below that gives an estimate based on the above, compare this with their figures.
