Lovely day here, how's everyone else doing?

Rubbish morning, sunny intervals now though but only just under 5kWh made today so far. Unlikely to hit my 200kWh aim for the month but we've made it to 193kW at least, ~21% ahead of PVGIS.

103.54kWh total for February, 2kWp, 18% ahead of PVGIS, not too bad.

195 Kwh for February.

3.92Kw, 30 degree, South facing in somerset.
missed 1.5 days this month as the panels were installed and had scaffolding up for 3 weeks.

Target 180 KwH

If you want to make a valid comparison between your own figures for February and those you think are predicted by PVGIS (or indeed anyone else) then you really shouldn't be including today's results in your total (or perhaps use just 25% of them).

This month has of course been two and a half percent longer than a 'typical' February.

Well you beat me hands down (proportionately). In fact till April when my shallow ESE panels kick in, I'm really living vicariously through the rest of you!

Target 123kWh's, got 120 by 28th, so needed bonus day to close on 128kWh's.

Target 218 for March, huge jump, but really gets going in April with 335.

So, 128kWh's with 3.6kWp = 35.56kWh's/kWp

Over to the Essex massive!

When compared with last year, my system has generated fifty percent more kWh this February than it did back in 2011, and is spot on the PVGIS estimates.

In fact, October, November, December and January production was much better second time around due to the milder/sunnier weather.

Lets hope it continues through Spring and Summer.

16.4 kWh today

286.9 kWh for month :j

and as promised my figures

points to note:

Projected estimate for first year £2100-£2300

Projected return of Capital 5 yrs 9 days

GH, I use this site to compare results against sunshine levels for each month. It tells you have much above below, or on target your area is compared to a 30 year average 1971-2000.

just choose sunshine, and the month and year. It does take a few weeks to update the current month, so Feb 2012 may not be available for a while.

you mean average the result, not remove todays result?

Excellent post. Just to add, its really good to have an energy monitor to get a feel for what sort of leccy appliances are using and when. I had a monitor for some time before I had the panels so I had a really good feel for what uses the most electric.

Note that if you use an energy monitor once you have panels fitted it will only be measuring your net import or export - this will not be the same as what you are using in the house.

E.g An energy monitor would only read 100w if you were consuming 800w in the house and your panels are producing 700w (import of 100w). It would also read 100w if you panels are producing 900w and you are using 800w (export of 100w)

I have 2 monitors on different wavelengths so 1 of them measures what is being produced by the panels and the other monitor tells me what i'm currently using....
