Solar Power Operation Time and Duration Per Minecraft Day[]

Minecraft Ticks Real Time (mm:ss) Minecraft Time (hh:mm)
Minecraft Daytime 0 to 12000 0:00 to 10:00 6:00 to 18:00
Solar Power Operation Time -540 to 12540 -0:27 to 10:27 5:28 to 18:32
Solar Power Operation Duration 13080 10:54 19:05

There are 24000 ticks in a Minecraft day, which is 24 Minecraft hours long. Since there are 20 ticks per second, a Minecraft day is 1200 seconds, or 20 minutes. Therefore, by the table above, one can calculate that solar power operates for 54.5% of a Minecraft day. Interestingly, IC2's developer must've mistakenly thought 12540 - -540 = 12000 or accidentally made solar power operate 540 ticks before the start of the day instead of after, as those numbers are just too convenient and significant (being exactly half a day cycle) to be mere coincidence!


Average EU/t of Solar Arrays Per Minecraft Day[]

HV: 512 EU/t * 0.545 = 279.04 EU/t

MV:  64 EU/t * 0.545 =   34.88 EU/t

LV:     8 EU/t * 0.545 =     4.36 EU/t


HV Solar Arrays and MFSU's Required to Power Max-Overclocked Machines[]

Macerator/Extractor/Compressor: 16 OC, 3689 EU/t

3689 / 279.04 = ~13.23 HV Solar Arrays

3689 / 512 = ~7.21 MFSU's

= 14 HV Solars, 8 MFSU's per Macerator/Extractor/Compressor


Electric Furnace: 13 OC, 1351 EU/t

1351 / 279.04 = ~4.85 HV Solar Arrays

1351 / 512 = ~2.64 MFSU's

= 5 HV Solars, 3 MFSU's per Electric Furnace


Recycler: 10 OC, 109 EU/t

109 / 279.04 = ~0.40 HV Solar Arrays

109 / 512 = ~0.22 MFSU's

= HV Solar Array per 2 Recyclers, MFSU per 4 Recyclers
