I am paying close attention to this thread, but for different
reasons. I have designed and will install next month an off grid
system for a high-elevation research hut. At 14,242' I believe this
will be the highest elevation
off grid system in the continental US (Alaska too?), at the
Summit Hut atop White Mountain, east of the Sierra crest in eastern
California (<a href="http://wmrc.edu/facilities/bar/summit.html" target="_blank">wmrc.edu/facilities/bar/summit.html</a>). For me it's sort
of a post-retirement summer working adventure. A nearly identical
system will
serve an older observatory at 12,700' in the same area. The Summit
Hut will get a roof array where winds of 190 mph have been measured,
I'm told. The roof has about a 5º north-facing tilt. <br>
<br>
I'm old-school too, thinking in terms of a 25º tilt to south. But
other than powering an internet repeater all year, the system is
only used during the summer months, mid-June to mid-October, when
the snow has melted and it's accessible by a long jeep trail. So in
that respect it's similar to a flat- or north-facing array in a
grid-tied system, where only summer gain matters much and a southern
tilt matters less that I want to believe. Jason's chart is pretty
useful here, suggesting that I should pay more attention to handling
wind loads with a low angle than maximizing summer gain.<br>
