09 25hrs.

Output from my 7.5kW PV is at this moment 48W.

No 3 Tracker, in photo facing west, Midnite controller of 2kW of PV Yingli Panda 250W panels has shut down.

No 1 & 2 Tracker still outputting at 40W. PV Panels are Sharpe 190W.

2.5kW 250W PV panels with mixed manufacturers, output from Sunny Island GTI to my mini grid is 8W at 230vac.

Also getting dark here. Can't tell where the sun should be through the cloud and misty drizzle.

I put new batteries in my auto-dimming weldo-matic visor tonight ready for t'eclisp t'morrow.
Knowing my recent luck, it will be cloudy. The sun will disappear behind the clouds and stay there.


Be very careful about using an auto dim mask, some only darken where arc is struck and there is a flash of light, a constant bright light ie looking at the sun won't make them go dark

We've got patchy cloud now and its great as you can see it perfectly through the not so thick patches, just need to keep an eye on the edge of the cloud and look away before it's too bright

09 44hrs.

Outputs now climbing, now at 105W.


Midnite controller just woke up.

But climbing fast on the voltages.

I will do another readings in 1 hour, then I can see what the percentage was.

Interesting that the Sharpe panels on the No 1 & 2 tracker with a Tristar MPPT controller, were still producing no matter what.

Nickle2, Might actually do a Full moon reading sometime and see what voltage I am getting.

No windy gusts, breeze back to an average breeze of about 400W for the Turbines.

Our voltage now 129 even if it is not as dark as before, (9.46am)
                                          It is getting lighter. Our turbine is still stationary, still too much resistance in the bank for the light breeze
  We are back in business,  129v x 1amp (9.53am)

Significant & noticeable dimming (not quite twilight, but heading there). but almost total cloud, so nothing spectacular. There were some breaks in the cloud, but well round to the North - maybe even over Raasay?

The birds didn't stop singing.

Totally clouded over here too in London, but it did get pretty gloomy and my solar panel output fell completely to zero!

Well, the reports were more interesting than the event. All cloudy in NE Hants, the sun came up and the sky was grey. It's still grey, but slightly less now. Welding visor put away until next use. In a word, *dull*. I want a refund!
 Garethpuk, thanks for your warning, I set the visor (speedglas 9100) to max sensitivity and darkness, so it goes black as soon as it is taken outdoors, so no probs there.
The bird song reduced by 50%, but the bluetits are still fluttering about, song-thrush feeding on next-door's lawn. Last eeklipse in 1999 everything went back to sleep as it was during the day, the re-awoke. This time they just had a lie-in and were late getting up.
It has stayed at the overnight low of 4c and has not started warming up yet.
How was it in the more northern areas?

For those that had cloud you didn't miss much. It was crystal clear here and I was hoping it would be impressive but sadly 85% eclipse don't make a lot of difference. It got a bit chilly and dimmed a bit and it was over. Never mind there is always the next full eclipse in .....Ooh well I will be dead then  Smiley

Bodidly - That's as maybe, but you'll be sitting on top of any cloud, so should get a better view!

Clearish skies here.
Like Billi not much cop with photography - just point and click as a rule - but dug out a filter from a former life used for studying burner flame profiles, bunged it over the lens and got this -

Absolutely no idea what it represents other than the sun with the moon in front of it but it was around about maximum coverage time. This is how the scene was when it started to get noticeably brighter -

PV bottomed at around 120w, wind did not change at all and there was only a very brief period of feeling cooler, not enough to affect the temperature recorder. Curiously the birds etc did not go quiet as I have observed with eclipses before.

Thick uniform cloud cover. Noticeable impact on solar panel output though:

Still a dim grey day, no sign of the Sun.

PV now at 550w.

So averaging out my PV output before and after the event......367W

My lowest PV Output was 48W

So roughly.... during the Eclipse itself at peak............ I lost about 86% of my normal PV Output.

Even though it was already grey and dim and no sign of a Sun or where it was in the sky, just dim grey, grey & more grey.
