Intronics Power makes the module shown in the photo. It is good for 16.2V max, but theu can be put in series in any number for higher voltage. You can put it across the battery bank rather than before the controller, so it will smooth out battery current, or across the panel input if your controller has trouble keeping up with rapidly changing solar conditions. Or you can do both. It will help system performance and battery life in both cases.

I think it's a little bit of a hacking job.  I think if you had DC panels and a central inverter and you tapped the panel outputs to add ultra caps you could hack them in.

@patb: Are there any replacements as such ? If so what is it, since I would like to know

i'm saying some caps to smooth the output of the panels on my roof.

 

if my roof panels are producing 28V  DC, a big cap will ride out small cloud drop out.

 

and it will make it a lot easier on any battery system thats added.  Reduce the high frequency cycle noise.

Pat,

Are you saying collect solar energy from the upper atmosphere and send it down somehow?

That's not a bad idea. 

Light will bend around the edges and still reach the ground. So, it shouldn't take away too much energy from hitting the earth.

Also, upper atmosphere is cold, and should keep the panels cooler.

Wireless power back to the ground? A really long wire? Drop charged batteries back to earth?

I've been thinking, that  it's really a big opportunity for smoothing solar PV Panels.

Put that onto a big solar panel and you should be able to ride out a lot of cloud overhead.

You're right on Cabe.  The "100W" number in the article is misleading and caused me to do a double-take while reading.  It's the Watt-Seconds (Joules) that provide the whole picture.  The cost per joule that is the biggest constraint.

The joule density of some super/ultracaps in inspiring. Still, the size to joule desity needs to improve. Our smart-devices would need a pack of super/ultra the size of a suitcase to meet the potential of the lithium based packs we use now.

For high draw applications ultracaps are a great choice, but right now the self-discharge is still a little high for other applications.  I've used ultracaps in a few motor applications and they can really extend batery life when you get past the internal resistance of a battery.
