I see two conflicting calculations for UU matter required for 1 HV array. Here's the item counts anyway:
+---------------+--------+----------------------+
| material | amount | Number of stacks |
+---------------+--------+----------------------+
| rubber | 6810 | 106 stacks, 26 extra |
| iron ingot | 5193 | 81 stacks, 9 extra |
| cobblestone | 4096 | 64 stacks, 0 extra |
| copper | 3597 | 56 stacks, 13 extra |
| redstone dust | 3082 | 48 stacks, 10 extra |
| tin | 2048 | 32 stacks, 0 extra |
| coal | 1536 | 24 stacks, 0 extra |
| glass | 1536 | 24 stacks, 0 extra |
| wooden plank | 256 | 4 stacks, 0 extra |
| diamond | 1 | 0 stacks, 1 extra |
+---------------+--------+----------------------+
The two numbers I found are 11,839 or 18,879. I did a rough calculation on just these numbers, which don't include the MV or HV transformers, and got 16,930. Assuming it was fully optimized, we'd be getting about 4 HV arrays per day if 1 UU was being generated every second.
