Good or bad

HiWondering if this is average or good generation from 2.02kw system for 11 months. Have generation of 1750 for this period. Panels are sw facing and Iam in north Aberdeenshire. Most seen seen made in one day was 13.2kw.

According to the clipboard carriers preferred calcualtion method, SAP,

2002 x 0.8 x 1.027 x 1 = 1644 hours per year

This is based on Sheffield and 30 degrees roof angle.

As you are a lot further North than Sheffield and your roof may not be at 30 degrees and you are ahead of the above SAP calc I would have said you were doing well.

Good, PVGIS says 1460kWh per annum for Aberdeen SW @ 30 degrees, building integrated.

Our 2.35kW system has generated 1760 units since Feb 29th. But we are in Devon (SE facing, 30deg, no shading).
Would say your figures sound very reasonable!

We've had 1x near-100kWh week (think it was 98 or 99 in the end) which shows the potential of our system, but of course it has been a pretty crap Summer all over the UK!

Aha you'll mean this What is a typical British summer? - Met Office
and this: Met Office confirms wettest June in over a century - Met Office
and .. Met Office: UK rainfall, sunshine and temperature anomaly graphs

Hope get better year next year with lots more sunshine. Even average sunshine would be better.

if you go to PVoutput.org you can download your system data and compaer to other systems in your area

Looks OK to me. Generation has often been better than in the south. A system on a property we have in north of Cairngorms National Park has done 910kW per kWp installed.

Just about same then. That's 1804kwp for my year so happy.

I'd say you've done well to get 54kWh in the last month, we're on about 8kWh a week at the moment (in amongst the floods!)

We have already passed the annual SAP prediction tho, with 3 months to spare.
