With the announcement of Solar City acquiring Silevo in part to jump start production of high efficiency solar panels, I thought it would be nice to have a thread that discusses what the differences are between common solar panels today vs the high efficiency panels of tomorrow. There may be something on this already in the Solar City investors thread, but it's an extremely long thread so I wanted to pull this out as separate. I honestly don't know what the differences are at this point, but I would like to learn. Some questions that come to mind are: 1) What is the actual output difference for same size panels? 2) What are the noteworthy construction differences (if any)? 3) What are the noteworthy installation differences (if any)? 4) What are the appearance differences (if any)? 5) Are high efficiency panels like would be produced by Solar City and Silevo already available on the market today? If so, what are the current cost differences and how much might costs of the high efficiency panels need to come down to make overall cost reduction a reality? Thank you to any and all contributors.
