I have to agree efficiency of fixed panels means to provide the power requirements mean that you have to install a system that is maybe 50 to 200% larger to get the real requirment of the home.
I used to install solar panels in the outback and we had to determin the requirements versus the panels needed in a fixed system. Fortunately in the outback due to extremes the efficiency was quite high.
It would be interesting to see what the real panel use would be ie: 3KW installation may only produce 2KW or less (average). I wonder how many companies know if asked.
It is interesting about the manfacturing process, I knew this but never really thought about it until brought up in this thread. Would be interesting to see if a more recent report is available or whether something like this is suppressed. That kind of report would produce a negative carbon footprint offset for solar installations.
New manufacturing processes may change this issue.
