2.5 kWp PV system, SSW facing, 45 Deg Roof. ABB Inverter, Monitor: 'Wattson'.

Last two days have finally given some better generation, with 14.1kWh (2.53 Os) and 9.7kWh (1.74 Os). But the interesting part (ok I've massively oversold that), but the rather boring part is that at the end of week 1 (and if average for the rest of the month), the ESE is predicting 93% of target, whilst the WNW is predicting 103%.
This isn't that uncommon, as weather can cause this some months and more easily some weeks, but it seems to be happening 'too' often. I've gone back and checked my PVGIS climate calcs, and they are correct, and I haven't deducted any losses for shading. Also the WNW has worse shading, and the ESE has improved (a tiny bit, due to the loss of a tree to the ESE recently, just as it started to become a factor).
So I'm getting ever more tempted to say that the difference must be down to the SolarEdge system (on the WNW) doing exactly what it says on the tin. The WNW system hit its annual target on the 4th October, though admittedly, generation on this system does drop rapidly from Oct onwards.
Not an advert, and I may be completely wrong (only 14 months of comparisons so far) but interesting (to me!)
One other issue, is it just me? Ok, let's narrow that one down, as the list is so, so long. I enjoy checking generation against the MET office anomaly maps here:

but they haven't been updated since June (and are usually done within a week or so of the start of following month. Maybe there have been cutbacks?

"UK Power Networks" is busy messing about with grid connections in S.Essex, probably in anticipation of the opening of what should become Britain's largest dry goods port - It calls itself London Gateway, even though I thought that the first service area on the M1 had bagged that name.
Anyway I was working at this PC, when there was an instantaneous power cut and reconnection; blink and you could have missed it.
The surge protector turned off my desk light and computer display, but the venerable Dell PC sailed through. The digital radio had to be reset manually as did the Sony analogue radio, though on standby it had lost its programs memory.
However other time clocks, such as the alarm clock, were not flashing their distress.
The Californian designed Italian Power One 3.6 kWp "Aurora" inverter successfully went through a cycle of instant shut down and restarting.
Fingers crossed for the next outage.0 -
