[RE-wrenches] Sanyo 186 Dbl

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,
