I noticed today that, after this prolonged spell of warm dry weather, there was a significant film of fine sand on my PV array plus the odd bird shot. So I washed it at midday having noted that conditions were stable giving a constant 1780W. Those of you with less accessible arrays will be pleased to know that it made no noticeable change to power output.

It literally came out of the blue! I spent yesterday morning walking Wife and dog over Ecton (copper) Hill by the River Manifold and it was cloudy but stunning all the same. In fact it was cloudy for most of the daytime. They say that copper came out of this hill at over 25% purity whereas the purity of modern copper mines is much less than 0.1% so that electrolysis has to be used. Anyway, we arrived home and I went into the stable just as our sun came out and gave a megapulse. 2498W the inverter said..............2498W! That is from 10 Sharp panels rated at 2450W, at an angle of 17 degrees and a Sunny Boy 2500HF inverter.
So now I can stop visiting the inverter so often and die happy. PV does what it says on the box.

Going back to your earlier post about electric shocks...... the day my system was installed in December and the installers had gone, I got out the ladder and cloth and thought I would polish off the fingerprints from the glass and frames (as you would with a brand new car on your drive) and check that there wasn't any cracked glass etc. As soon as I touched the frame (before I did any polishing) I got a shock in my hand and knee which was resting on the rung of the ladder. I guess it was about 150V (I am so used to these things by now I can guess the volts) I carried on as it was so important to remove fingerprints and I got more shocks or more like tingles. The inverter said there was no leakage. I have been up a few times since and there is no hint of a tingle since. The panels are not earthed as I have a TL inverter. Could it be that on first power-up, a charge is created between the cells and the front glass as the cells suddenly go from zero to max volts during a midday install and then over time has all soaks away.
I didn't have a bucket of salt water...honest Grin

Well it would worry me Gambot but I'm not an electrician and so I can't make a useful comment.
