hm, assuming that you don't use GT, with the current ASP: you need 9 uum (2 for the sunnarium, 7 for iridium). so you need 166,666*9 = 1499994 eu for 1 ASP; assuming 20 tps, say effective eu/t = 4 eu/t (1 eu at night, 8 eu at day, and sometimes you have rain) so you need....
1499994 eu / (80 eu/sec) / 3600 (sec/hours) = 5.2 hours. after that 5.2 hours, that 8 eu/t is free for you, you can move it anywhere you want without even thinking about re-fueling them.
and then for the second one assuming you already get the free energy from the first ASP: 1499994/ (160 eu/sec) / 3600 = 2.6 hours.
... after the 10th; 1499994/800 eu/sec/3600 = 31 minutes.
If you are using GT default mode, I'm certain that you won't use this mod for main power system, more like a battery that you can carry everywhere (for GT automation perhaps)
