[RE-wrenches] Sanyo 186 Dbl

[Tump]

I have 4 of these modules set up on my shop, 45* tilt, 5 feet out from the
wall,clear unobstructed back & I get 900-940 watts in full February sun. Red
barn paint I have thought of using corrugated Alum roofing placed
horizontally on the wall, despite what Sanyo says, you get a piece of foil
faced insulation reflecting on them & the output really goes up! Personally
if you have a site that one can take advantage of the additional light, the
performance verses price works well in colder climates. summer time 750-800
watts. Inv is a SMA 1800 wired in series of 4.

The only places we have seen where those are effective at all is in
applications such as car ports, awnings, parking areas, and the like where
the backs get a fair amount of reflected light. Since that light is nearly
always pretty diffuse, rails don't seem to affect it much. But you don't get
much extra either way - I think the best case scenario I have heard of is
around 7% more, and that was at a ski resort on pole mounts with a lot of
reflected light.

I have been asked how these panels have been doing if installed with say
Unirac mounting for lipped modules, and had the rails behind the back face.
Does anyone have data on performance? I have not searched hard but after
moderate investigation I thought I'd ask all of you.

Thanks,
