another perspective on comparing different brands of panels

[Gavin A]

now that's a good idea. Are they all nominally the same rated output panels?

 

[Blueflash]

They are all 250's as long as I am aware. It has opened a few eyes and as a company we have switched module.

 

[SolarCity]

Very interesting. All installed in similar conditions?

 

[Blueflash]

All on same ground mount, so good aspect. The online software promotes data analysis with many ways to compare.

would the positive tolenece effect the indivual panel, some can be 255w when first installed

These are the graphs for today for our horse race. REC, Hyundai, Bisol, Sharp,Yingli, Suntec, Trina, Perlight, Sanyo.
I could give the log in details but my boss would kill me! lol

It's interesting to see that Sanyo perform so well early in the morning.

I don't understand Sharp & Bisol drop so much at 1700.

Just guessing - they may get a bit of late afternoon shadow first, as the others drop off very rapidly later, our own systems tend to give a very smooth tail off in the evening - any chance of a photo of the array?

Great - really interesting thread here and very useful table thanks..( i like your detailed guide also to each column

if you did want other real-time information or a perspective from other installation owners you could also check out a free pv monitoring site such as PV-Log. This is a social monitoring site..no hardware costs and free to use, make solar friends, showcase your installations etc.

I'm new here so also hi to everyone!
