November 2014

November 2014
Starting the month 41 units down on the year.  There's only 104 units estimated for the whole of November so it's looking unlikely we can pull them back which is a shame.  Still, we'll see.

It started off well but in the end we only generated 75% of estimate for November - been grey and miserable most days in fairness.  Could have been worse as last day of month was a decent day - when I was up in the attic around lunchtime we were already on 5.5KWH which was much higher that most days.   Such is life.  We're now about 67 KWH down.

Not strictly solar but energy efficient none-the -less, I've put a 10W LED Security light up on Phil's shed and it's marvellous.  £20 from Maplins.

October 2014
Well so much for being up on the estimate.  Overall at the end of October we lost 41 units so we're down to 98.6% of estimate.  Pah.   Hopefully there will be a bit of sun in November to make up but we're into the season of diminishing returns so damned unlikely.

September 2014

September 2014
Well  after August bizarrely seemed to exceed expectations with 9 KWh more than the 363 estimate we'll have to see how September gets on with the rather weedy estimate of 280KWh. which is only marginally more than March!!  Can see why too the nights are really closing in quickly.

Really pleased that we generated 4% more energy than the estimate in September not only that but we're now half a kilowatt hour up on what we should have generated so far!

August 2014

August 2014
August in review - actually outperformed the estimate by almost 2.5% - very peculiar as it's been grey and horrible for most of the month.   Have also been too busy to keep the spreadsheet up to date every day so perhaps this is the way it will be going forward!!!

July 2014

July 2014
Well June might have been a bit rubbish but July was anything but.  Actual generation was 22% over estimate.  The excellent amount of sunniness has brought the deficit from bad months in February, April, May and June to less than 1%, just 17 units short of what should have been generated.  Very pleased!

June 2014

June 2014 

So far in 2014 we've only generated 93% of estimate and the months are starting to fall in estimated generation stats - June should be 4KWh less than May.  It's been a bit grey at times so that could be some of it but I think I might also have over estimated the efficiency of the invertor.  Never mind.  We got first payment for it the other week anyway £132 - now got to get the bosskat into making best use when the sun is shining!

June another month down on what it should be.  We generated 403 KWh rather than the 432 estimated so 6.7% less than forecast.   Such is life, I suppose.

May 2014

May 2014

Overall - 408.16 KWh generated about 28 short of estimated but we did have quite a lot of wet weather.

13th May 2014
Hadn't mentioned it before but about a week ago I got a Qualcast Li-ion Cordless Grass Trimmer - 18V. The idea being that we'd charge it up during generation time.  Anyway, it's rained every day since so Tuesday 13th was first opportunity to use it and it worked okay - obviously it's not got as much umpf as a petrol one so it takes a bit longer but I was unable to use up all the battery power so that's a good sign I think.  Also used it to tidy up our allotment so that's a bit good too!
