Not solar again ?

the higher voltage at the controler has something to do with it. Ieven find this with my 24V panel in my caper. at 7am I will be fetting between 0.5 and 1amp of charge out of the 325 watt 24V panel but my 480 watt panels (12V's in parralel) will be putting nothing out for another hour at least. so low light/shading get better preformance as the voltage that does come through is high enough to start the charge. A MPPT charger is an important part of this equasion also in my opinion.

Read my post again. I find I'm getting what your talking about with today's modern panels.

I also have a Victron 100/30 SCC, so that's a moot point.

Perry Unisolar made panels with diodes between every cell. Wired in series parallel, they do work in leafy shade, and in rain too.

There is one other currently made panel that has this feature--but they are from Germany and I have been unable to find a source to buy them from.

In general, parallel is better, but with a good MPPT controller more watt-hours may be harvested.

So the panels you're talking about are unobtainium. I'm talking about current panels, that are easily obtained, that the sales person at Northern Arizona Wind & Sun recommended because of their superior light gathering ability.

Again, I already have a quality Victron 100/30 SCC.

Enjoy,
