[bldg-sim] about pv simulation

[JRR]

Of Course!! If 650 W/m**2 direct beam lands on horizontal patch June 
21st, and.........
we use the newest Cyprus Semiconductor PV cells - whopping 20% efficient,
we get an additional  130 W. That is load avoided plus power produced >>
780 W difference from doing nothing.  PV is VERY expensive  unless you
need  no-moving-parts reliability, so maybe it should include lower cost 
augmentation ---
moving am/pm wing reflectors,  and/or seasonal tilt when it's not in 
space.......

BTW a good ammonia superheated cycle will
crank out  35 -- 38% with an ~ 8:1 concentrating collector........
I'll take the NH3 at over 100 kW output.

PV has political merit, BIPV even more,,,,,,,,
Why not call these things  Photovoltaic /Thermal  -- PV/T collectors ??
Is that  thesis on line somewhere ??
