Renewables: "talking 'bout my generation"

I think that's probably the worst day ever ! Of course power was off all day and that 223Wh has been generated since 7pm. And I did get unmetered electricity until then.
Fairly confident tomorrow will be better

And of course it was. 18.87 kWh for 2nd August

Since for one reason or another I haven't posted any results this month, here are the missing ones :-
3rd 20.71
4th 9.82
5th 8.82
6th 13.59
7th 17.85
8th 16.99
9th 14.79
10th 9.12
11th 14.34
12th 18.14
13th 13.86
Today 18.94

Month to date : 196 kWh
even allowing for zero generation on Aug 1st we're still ahead of pvgis forecast for this half of August.


And today is just a bit special. It's the last day of my May-Aug quarter.
Generation during the quarter was 1539 kWh
so I'm hoping to receive a payment of £745.80 (though on recent form probably not for another 6 weeks ! :mad:)

It's also the second anniversary of fitting day.
2011-12 generation was 3550 kWh
2012-13 generation was 3675 kWh
So no noticeable deterioration (yet !) of panels as they've aged.:j

Only 3.0 O's today; thanks to Tunnel's accurate forecast.....:mad:

We are close on quarter end dates and gen figures.
I sent in my 3rd quarter numbers yesterday
1556 kWh or 389 O's:D

With this payment I will have over 25% of my initial outlay back:)

+ lots of free leccy and less gas usage:rotfl:

3.44 O's yesterday

InVestor_2

£9.98 yesterday, so near yet so far (20.6 kWh)

Now back within single figures for annual forecast

EricMears

Total receipts in 2 years will be £3416 or 28.5% of installation cost.

Y1 £1633 (13.6% ROI )
Y2 £1783 (14.9% ROI )

Best of luck, hopefully by Friday you'll be able to play along with us, unless of course you can find something better to do with your time! Mart.

Well, the 4kw system is in and has been generating this afternoon and the iBoost has been heating the immersion tank, so I might have a celebratory wallow in the bath this evening. Black panels and a very neat job on my roof. I've an Owl-pv monitor and it is fascinating..;) but I've an awful lot to do on this house so I won't be here every day!

One big, big tick off the list though, and another when I've done all the FITs paperwork.

Day yield of 15.74 kWh today.

Given that I should only need 12.2 kWh /day for the pvgis forecast (although I actually need 12.7 kWh to make up for missing the 1st Aug ! ) that's pretty satisfactory.

Well well well,

Don't you just love these weather clairvoyants. Was supposed to throw it down today(need some for my garden waterbut) and yet I still managed 3.75 O's with not a drop of rain to be seen:(

For your personal forecast for tomorrow see below,

There should be a chance of some sunny spells around but with the possibility of a few showers or longer spells of rain although some parts may stay dry.

PS. Well done silverwhistle, nice to see someone taking the bull by the horns instead of !!!!!footing around. Don't worry if you don't post every day....every other day will do:rotfl:

Like a fine wine Eric, getting better with age(hopefully):D

I sincerely hope you're right ! If annual output continues to grow at 3% pa , I should be generating around 7000 kWh/year in Y 25 and if inflation rate is also around 3% pa that will be worth £7000 or 58% ROI for last year of the contract. :beer:

But I'm about as confident of that as I am of our weather experts getting the forecast correct every day for that period :rotfl:
