Cloud edge effects... WOW!

Many would regard watching their array output update every two seconds akin to watching paint dry... However...





When you see your 2970W array output 3975W for a moment, it gives you the tinglies...

I think I just smurfed myself...

I'm assuming directly into a Victron branded diaper

Are you underpanneled on that controller? Which model?

Yep at about 50%. MPPT 250/100, 5800W max output.. closer to 5500W max at my typical peak charge voltages.

LOL... just happened again...



Worth reminding folks that I have the potential to get nearly 1200W/m^2 due to the thinner air. This is simply a confluence of positive factors: lower air density, lower temperature (4°C), variable 5-10mph winds blowing across the panels (basically hitting both front and back), and cloud edge effects. This is in spite of a 29.5° tilt that's about 2 months from being optimal.

Rebrand your panels and make a million on Amazon. Peak energy production*
Don't forget the asterisk.

Yes sir, nothing more fun than bright, cool, fluffy white cloud spring days and I see my PV output jump a bit more than the sum of the panel ratings! Absolutely exhilarating

Dupe post

Can these momentary overages damage scc's?

Not likely. Someone should have already pre calculated PV voltage at the colder temperatures the panels are likely to see.

I have midnite classics and they have specific 'max output' control so they won't pull more than they need for max output or a user setting to less than max output. So it's not possible to 'damage them thru an abundance' as long as the voltage of the strings doesn't exceed the max specs.

Are we sure the sun didn't just have a major fart?

everyone else is praying for clear skies and this guy is praying for clouds. love it !

So when is someone going to come up with vapor sprayers? That magnifies the suns inensity just in front of the panels while keeping them cool?

 

[Danke]

Hey

 

[time2roll]

The trick is to aim the edge part direct in while avoiding the shade part of the cloud drifting by.

It's the current that increases not the voltage.

Before I go outside and try that, could you sketch that out for me, so I’m sure to set it up correctly?

Yea it did northern states likely to see Aurora tonight.

Bawahahahahaha! That is the funniest shit I have seen posted on this forum!
