Well I didn't when you first asked this on the other thread, but now I do! Thanks for the suggestion.

Now that it is sourced, I can see that you used the maximum values for the losses, which makes this a fairly accurate Minimum Net Efficiency value for solar.
Solar is getting better, and cheaper. Should the InGaN full spectrum cells become reality in a thin film product, lookout.
BTW: Are your angle calculations based on flat surfaced PV's or did you consider the pyramidal and spiked surfaces that have been in use for about 12 years?
Thanks again for the work and effort you put into this.
