Cosine and atmospheric loss of 65% sounds quite reasonable to me.<br /><br />An online calculator has alt/az of sun at 4PM in Boise as 56.1/243.5 degrees (and maximum alt at 69.5 degrees @ 1:40PM), so cos(243.5) * cos(13.4) =~ 0.434. There's most of the losses right there.Sam's Hideouthttps://www.blogger.com/profile/17861031623526621055noreply@blogger.comtag:blogger.com,1999:blog-2807403883562053852.post-79263441387209208562014-06-30T10:11:44.554-06:002014-06-30T10:11:44.554-06:00It is putting out over 14 volts.
