Yep, that's it, brilliant, thanks.

So looks like S. Wales got 150%+ of average July sunshine last year. Which answered the question in my head, will generation track sunshine levels, or will temp changes balance it out a bit.

On the plus side, I'm pretty sure I've seen the same in reverse, where poor sunshine levels have been lower than my generation percentage, presumably/possibly because panel temps have helped to negate some of the losses.

Apart from one 82% and one 131% all my results fall between 84% and 112%. Sort of boringly stable. So far!

Hi

It'll likely be the average on a nominal flat surface, so being at an angle the orientation of the array will make a difference. We tend to get more cloud/mist/fog in the mornings than the afternoon, so our array probably benefits a little from a Westerly aspect as any clouds or mist reflect & refract light onto the panels in the morning whereas a clear sky just leaves the panels in shade, also, as you mention, 150% of average summer sunshine will certainly increase the average panel operating temperature - however, I still find taking the (averaged) anomaly data into account useful ....

3.2 O's for me folks... Need another 8.53 O's over the next two days to keep the monthly curve going upwards since Dec '13.... could be a close call.....

Edit: 4% above PVGIS todate:....

4.4 O's or 17.6kWh here today :T

Only need another 20 to hit April PVGIS.....O's that is :doh:

3.6 O's(23.8kWh) for me today, need 17kWh from my SSW in next 2 days for that to make Aprils PVGIS estimate, forecast looks good for tomorrow too

HI

26/4 2.43 O's
27/4 2.95 O's

Yesterday 3.46 O's

To catch up with last April 2013 generation need to make another 20.43 O's in 2 days.. impossible.. oh well you win some and you lose some..

One day I get Ys next day I get Os then Ys then Os.

My generation just seems to YOYO.

Another 3 O's in the bag today, my WNW only needs 3kWh tomorrow to hit target, both my ESE & SSW need 10kWh each.

Any chance of you lending me a few of your spare kWh?:)

Need to make 15 O's tomorrow to hit April PVGIS:(

2.5 O's today:D
