1. sailingdad is right-- even one or two percent shading will make your panel useless. take location very seriously.
2. top-of-the line monocrystalline panels brag 18.5% efficienct right now; lowest grade amorphous are around 11%
3. theres a new kind of panel called "monocrystalline seeded amorphous" which brings up the efficiency of amorphous panels to about on par with polycrystalline (15-16%), with the added benefit of being flexible. they are great because they aren't as delicate as traditional glazed panels, and cheaper too. no idea about marine application of that type, though-- anyone else?
