Solar Panel Question...........

Of course if it was stainless, it wouldn't have to be 2" in diameter to be the same strength.

THose pics are on my other computer so I will need to just describe it.

I measured out the panel sizes. I had aluminum angle iron cut and welded to those sizes to full support the panels. THese were then welded to the arch. The panels sit down into the grid - each panel supported by a seperate grid.

Cruisingdad,

Nice setup.. The numbers of 205 amp hours per day out of a 520 watt panel (ie, 4x 130) are pretty good.

If you dont mind, is this using a MPPT controller? What part of the country was it measured at and what time of year? (assume it was also measured with one of the xantrex charge monitors).

Note - I had posted here earlier about a rule of thumb of .234 amp hours per day per watt. Using this equation would only predict 121 daily amp hours for a 520 watt panel. So Im just trying get another data point...

Yes, I am using a Outback MX 60 MPPT. It calculates the AH it puts out to batts. That was measured in North Texas.
