It's just a pity that our solar system only has a single sun. This product was really built for a 2-sun solar system. It is nice to have a module that looks good from underneath. That is probably the biggest benefit. To claim any improvement other than aesthetics is difficult. I have seen data that suggests it works better, but unless you have an additional pyranometer measuring back light, all claims are dubious. It could be that the product is simply underrated, which is true of many Sanyo products-that is a very real bonus.

Specifically - a 6/12 white metal roof @185dg. - horizon to horizon window. Have potential application for 200kw+ array. Would like to have more than a "we think" number in the proposal. Holt E.
