Renewables: "talking 'bout my generation"

Martyn1981

The late lunge for the line in sunny Cardiff continues. We got exactly the same yesterday as the day before, 22.9kWh or 4.1 Os.

Have moved from 8 behind target, to just 3 behind. Today's target is 18, so will need 21+ to go positive in July. Forecast is a stunner, so should be fine.

However, the full story is more interesting (to addicts like me), whilst I hope for 100% overall, the ESE will be 94% and the WNW 110%, so weather this July has been significantly better in the afternoons than the mornings.

In fact, this will be the third month in a row where the kWh/kWp from the WNW are higher than from the ESE, which shouldn't really happen. Strange weather!

In spite of all around me complaining of poor weather - and indeed that would have been my own view if I hadn't seen the figures ! - I'm already comfortably ahead of the pvgis prediction for July and looking out of window am pretty confident of a good day today.

I suspect that the answer lies in there having been quite a bit of cloud around this month even on reasonably bright days. The shallow angle of our panels means that they'll benefit more from bright clouds than would steeper ones.

If the same is true for Cardiff, then clouds to the North ought to be reflecting more brightness than clouds to the South would allow sunshine to filter through them.

Kaboom! Smash through that prediction and still going.
Must be a cracking day at home.

My system generated 162 kWh during July which is slightly above the PVGIS Climate estimation of 160 kWh for the month.

July 2015 - 162 kWh
July 2014 - 189 kWh
July 2013 - 194 kWh
July 2012 - 157 kWh
July 2011 - 163 kWh

As forecast (by me this morning ) today was indeed a good day and brought month up to 515kWh (or 18% above pvgis)

Watch this space : I should have four full years results to report in a couple of weeks time.

Not a brilliant month, 224.94 kWh, 4.3% below SAF PVGIS.

July 2015: 224.94
July 2014: 278.68 (best month ever)
July 2013: 276.80
July 2012: 218.22

First month for me returning 539.1 kwh against a prediction of 431.33 kwh so very pleased so far with a 25% better yield than expected :j (And I thought the month was rubbish!)
