Renewables: "talking 'bout my generation"

Dave_Fowler

June 30th saw the end of my 4th year of generation from system 1. It has been the best year since installation on 1st July 2010.

Year ending:
June 30th 2011 2666 kWh
June 30th 2012 2745 kWh
June 30th 2013 2574 kWh
June 30th 2014 2808 kWh

For comparison System 2 generated 2825 kWh for the year ending 30th June 2014.

It has also been the best June.
System 1:
2011 341 kWh
2012 300 kWh
2013 327 kWh
2014 359 kWh.

System 2:
2013 346 kWh
2014 390 kWh

As you can see, the annual outputs of the two systems are roughly the same, but system 2 does better during the summer months (because of the roof angle).

Piccy of my Inverter today, just before it nodded off;)




Only just over 7 O's today:rotfl:


Before anyone asks...the gap is where I took 1kWh of the total (my Inverter reads 1% higher than true):D

If I check tomorrow after this adjustment, it will show 27.47kWh

Generation meter actual read is 28.1kWh for today:T

I imported just 49 kWh of electricity this month - roughly a quarter of pre-Solar import days.

That's mighty impressive. Our 72kWh is probably down from about 200 to 220, so approx 1/3. I was pretty chuffed, but now I'm jealous of your improvement. Any tips? Short of switching off Granny's iron lung at night, I'm not sure what more I can do?

Today was a monster, got 34kWh, 6.1 Os very close to our best ever. If it had just been 1 day earlier June would have been a 3/4MWh month. Oh well, there's always next year, or another freaky July.

True enough...where's that 1kW kettle:think::question:

Mine is on the Kitchen worktop, where, may I ask, is yours..:rotfl:

143.76 Os for me...:D 564.111kWh on my 3.924kWp system.

So okay it was better than my result; I'll be watching....

Wow, that's a lowww figure, how many candles did you have to burn to get it to that

Don't fret, he has probably got strong street lighting or a gas oven...:rotfl:
Anyway, on the brighter side a/an Hawaii +0.25 O's for I.....

Only bought 203kWh this month too with 4 single units of gas(multiply by correction figure what ever that is)

As a suggestion to this thread; would it not be of interest to post say, end of month gas meter readings; as in units of gas meter readings: rather than using the complicated correction figure on this thread? Merely out of interest. Any thoughts.....

To those early risers the local school is looking at installing a 20.5kWh system of 82 panels. To those of you with experience of larger systems, how much do you think system like this would cost to install. It's a single storey pitched roof installation. A very rough price is all I am looking for.

Rough price would be around the £20k marker. possibly less depending how hard they are prepared to barter. Below is a price for a 10kWp system to give you an idea.

You'd certainly need to say if your meter reads in cubic metres or cubic feet. Both versions are in use. And then we'd need to apply the multiplication factor to convert between cubic metres to cubic feet

The only absolute way is to quote kWh as the correction factor changes region by region and sometimes quarter by quarter. The correction factor is given on your gas bill and is adjusted for your version of meter; so it only needs a calculator to get the correct kWh.

Wouldn't go inconveniencing the granny just yet... I'm single, so less laundry, ironing, electricity usage all round. All lights are LED/low power bulbs, TV only grabs abut 45W (not bad for a 55"), that's LED too. The older and smaller LCD sucked 130W or so.

What T said, probably around £1k/kWp from around 10kWp onwards.

There was a recent thread on Navitron (I'll try to find it) but only a small system, and general basics. However, one of the installers (Gavin I think) mentioned that there are additional costs, such as greater insurance, access rules etc etc.

Not a bad place to look/ask as you'll get advice, and the site owners themselves may be able to provide quotes - Sorry if that sounds like an advert, just a suggestion.

Edit: here's the thread, not much use, but a start:
