all you guys with your fancy charts. I had to try it. So after some labourious lamenting of libre office calc. I get a total of 317,120 watts over the last 82 days. Ignore the 0 watts day. I loaded new firmware for my controllers that day and it left me with an extra day at 0 watts.

I'm off grid. So the chart outlines the power I created and used. The days I run the dishwasher are pretty easy to spot.



and also for comparison: In the spring of 2011 I paid $500 each for 4 250 watt mono panels (red: Panel set A). I then bought 2 more at $425 ea. I later found 2 more at $200 each (Blue: Panel set B). All the panels were used.

I run two 1kw arrays. One fixed (B) at 60 degrees. And the other is adjustable (A). Here I set 30 summer; 45 (my latitude) spring/fall; 60 winter. It makes quite a difference to the power output. Something not fully reflected in the stats as, of course, I could be making considerably more power if I had a place to put it.
