Renewables: "talking 'bout my generation"

EricMears

Rather a good day today - 26.35Kwh.

However (& being rather greedy !) it could very easily have been even better. Generation curve was indeed a classic 'normal distribution and sky certainly looked blue & cloudless but I'm pretty sure there was a fair amount of very diffuse cloud around as I never really exceeded 3.01Kw. With an extra 1Kwh from (say) 10 till 4 we'd have been way over 30 Kwh.

something had caused the solar MCB (shouldn't that be an SCB - secondary circuit board?)

MCB - Miniature Circuit Breaker.

It's also a consumer unit (CU), not a circuit board. You could label them as CU1 and CU2 or Main CU and Solar CU etc.

23.6kWh here (0.6kWh less than our record) and yet I don't recall the power output getting much above 3kW due to ambient temperature, limited wind and a lack of cloud cover to cool the panels.

We've now caught up with PVGIS target and the weather forecast suggests we'll now beat it comfortably.

26.1kWh here - like Eric the tip of the peak was less than we've had but it was an almost flawless curve so probably a combination of a bit of haze and the heat that knocked it down a bit. Still not too shabby for a SE/SW split system!

Kevin - bang goes the "older" theory then!

On the more general grammatical point, there really isn't a hard & fast rule about when agent nouns end in -er or -or.

A promoter is human but a motor non-human - which might support the KernelSanders theory. However :-

A driver is a human who drives a car but a screwdriver is a (non-human) tool.

Professors & professers are both human.

A chancellor is human, so is a chancer.

Whether talking about the support for a drawer or someone who runs, runner always ends in -er. And of course a drawer of water (or pictures) is human and a drawer to keep your socks in insn't.

etc. etc. . .

That was very entertaining Eric, and to further rubbish my theory, miner and minor are also both human!

Easily a record today with 27.02, despite never exceeding around 3250W. There was a fair breeze, so I think that low peak was more to do with haze. If you looked towards the horizon today from central England then you would notice that the blue got less and less intense the further away you looked. 30+kWh should easily be possible when the haze thins out.

Today 16.5 :jHave to remove the shade to keep em cooler:rotfl:!

Very similar to yesterday but slightly less generation : 25.1 Kwh.

Needed to go up on roof late morning so felt panels. They were pretty warm but not really hot.

Fairly confident reduced peak (only 3Kw again today) was caused by 'haze' rather than any temperature effect. Went out after lunch and view of distant hills was decidedly hazy.

22.6kWh today, fractionally less than yesterday's 23.6kWh. Long may the fine weather continue!

The jury's out here as to whether the reduced peak output is due to haze or temperature, but we barely hit 3kW today.

Shame the BBQ doesn't run on electric :rotfl:

I've found a similar pattern in South Devon. 25.0kWh today, down from 26.3kWh yesterday. Both below my best effort of 27.9kWh on 11 May.

25.0 yesterday so obviously haze building up - I was expecting a lower figure as it was quite misty when we got up and that's reflected both in the graph on my monitor and also on the weather station solar graph. Today looking rather grey so far so maybe a lower figure again - weather station currently showing 220W/m2 - needs to be in the high 700's for 3kw generation. Forecast looks brighter for this afternoon and through the weekend.
