Anyone tell me please if this is good/bad/average for solar energy production

Our panels were fitted on the 28th of Feb last year so that is just over 10 months and the 20 panels have generated 2944kwh so far.

Wonder if there is any sites where you can get an idea of how well or not your solar energy produced compares with elsewhere.

That's in the right ballpark for generation. Depends on direction of roof-facing and angle of roof.

Plug your numbers in here.

Cheers mate.I'm a kick in the teeth of where I should be with two onths to go.

Hi Birnam, I'm just down the road from you in not so sunny Ayrshire and last calendar year I made 3344 kwh off 3.75kwh of panels:)

Hi Birnam, Had our panels installed a week before you and we're on 3010 so far. I think 3100 would be realistic for our first year.
I also heard that 2012 was the second wettest on record. Since rain comes from clouds and cloud affects PV output I am hoping that 3100 is below average. Running the numbers over 25 years, using 3100 as an average and assuming 3% inflation. I was surprised to see a cash return of £52k!
Quite a bit better than I was expecting. :j

Yes, it makes a Cash ISA look a bit lame. :j

Hi to all, my figures for 2012, system 1 1885Kwh, system 2 3001Kwh, export meter reading 4001 kwh. I have 2 systems 1 is 10 panel and 2nd is 16 both facing south, living north west of Inverness.

Wow....two systems connected to the one export meter then ?
More daylight hours in Inverness in spring/summer contributing to your high export figures or more your 26 panels ?
