Just two weeks away from the day a year ago when we had our panels fitted.
The estimate from the above was 3110 kwh for the year.It was a nice sunny day in Glasgow today and my meter is now reading 3106kwh.
Impressed with the accuracy of this site.

A couple of days ago it was one year for our installation. It had 3709 on the meter with a PVGIS estimate of 3720, so that is pretty accurate :beer: (especially given that the weather from one year to the other can be quite different).
More importantly: the installation is behaving itself and producing according to its specification :T.0 -

Couldn't agree more with your last sentence

PVGIS estimated 2960 for our installation.
Our first year with panels is coming up on Thursday 21/2/13 and we've clocked up 3135 so far.
Our installer based their proposal on 2760 units so, as you can expect, we are over the moon.
I just wish I could point our panels south!4kW PV System installed 21/2/12: Aurora Power One 3.6 Inverter
11x 250w panels West; 5x 250 panels East.
On course for 19.8% ROI in Year 1.
