Yeah, I haven’t figured out how to measure the output of the charge converter without frying my multi meter, nor how much is lost in going to the battery. It’s noticeable though. FYI, I took smaller versions of this to Africa and measured them down there two weeks ago. 1.4 * more amps.

Very nice. But it seems like you’re measuring the open cirquit voltage and short cirquit current. But in a system delivering power you’ll be somewhere in between. Modern inverters for this purpose have Maximum Power Point trackers which seek the optimal balance between current and voltage. Nontheless your power output will be lower.
Anyways, nice work and good luck!

FYI, based on my tests in Namibia in mid March, 2009, this panel should output about a max of 80 – 90 watts in the midday sun. Will retest in the summer to see if this is the case.
