Renewables: "talking 'bout my generation"

jackieblack

14kWh for us yesterday, but June's graph looks like roller coaster track!
Daily kWh gen for June, so far, 4, 7, 2 , 9, 8, 11, 4, 5, 8, 12, 1, 3, 11, 14

Hi everyone - I've been lurking in here for a while but finally took the plunge and got installed yesterday afternoon ratcheting up 3.1KwH between approx 4pm and 8pm.

Like anyone with a new toy, I checked the generation meter at 8am this morning and was excited to see another 0.6KwH :j

Today's first full generation was 13.5KwH, which given the weather (torrential downpours and heavy grey cloud) I am quite pleased about.

I've read a lot of posts here from members who seem to have spreadsheets setup with formulae to calculate targets per month and ROI compared to ISA investments. Can anyone direct me to a spreadsheet I can download and work my own figures into?

I'm also interested to know which provider is best for the FIT registration and where can I get one of those nice geo solo monitors from ? :cool:

Hiya, congrats on the new toy.

Section 5 on here:

gives advice on entering your details into PVGIS to get a pretty good guesstimate of expected annual and monthly generation.

Hello xcntalien,

Welcome to the 'funny farm'.:rotfl:

From my limited knowledge; any provider is suitable as, I believe they all currently have to pay the same rates.

As to spreadsheets: I think most people have designed their own to suit their own interests. I will certainly be willing to share the one that I have with you, from it you can input your own criteria etc. I will PM you later with a contact e-mail.

Todays Gen figure: 10.9kWh:T

Hi all

Today figures for me is 9.19, 2nd best figures since I had SP installed.

Mart, on the above, when input details are entered; should the mounting position be intergrated or free standing? I always thought that intergrated was built in, with no air space below? If I am correct, then normal roof mounted SP's are classed as free standing, as they have an air flow beneath them? I expect to stand corrected.:rotfl:i.e. View the help section of the above link to section 5

There is another thread talking about FIT payments which might be worthwhile reading. EON seem to be awful and Scottish Power quick at paying from what I remember.

I get my elec/gas with SP and in my wisdom signed up with Good Energy. This was a bad move.......entered my 1st payment online yesterday to be told to expect payment in August!!! SP FIT customers have mentioned a week. Sigh.

Have fun checking the output. I don't think I'll ever get bored of it

The thread is here and I just realised that although Good Energy pay slower, its only the initial payment thats slower as you're always paid every 3 months anyways.

I just wasn't prepared for the month long delay combined with my paperwork not being complete leading to being registered over a month late. What made me mad was then having to complete even more forms and supply a EPC as the new registeration date was in May! But as long as all is ok now then maybe I won't move.....

Hiya Oscar, it's a good question that's puzzled me a little. I don't know what the official answer is, but I believe that building integrated includes 'our' way of fitting panels, as well as the method of removing slates/tiles and fitting into the roof, which I think is actually required in France (?).

I say that because having looked at some of the kWh/kWp outputs of the standalone systems that some people have (on other forums), those systems do have higher generation due to full cooling, whereas our systems get some air flow behind them, but are still married to reasonably warm roofs.

It would probably be helpful, and more accurate, if PVGIS had numbers for building integrated, roof mounted and standalone.

I wish I had power optimisers on my lower roof as 3 panels are roof mounted and the other 2 were installed as a canopy for the back of the house. I'm sure it would be fascinating (to me, and equally odd people!) to see exactly what wattage each panel was producing during hot weather.

Don't take all this PV stuff too seriously - otherwise you'll end up like me! :eek:
