Dear Mr. Paul Gilman,
Sorry, there is still a point I can not understand.
"Solar position table" and "Incidence angle modifiers" are for the same purpose.
I loaded the example LFR project in SAM and run for not only "Solar position table", but also
"Incidence angle modifiers". The results are below.
Everything other than "Optical characterization method" were remained without changing.
Could you please say us why the difference between their "Annual energy" is big.
