Space Stations as Resupply depots...

[Suicide Junkie]

The main thing is... why do you really care if they use a couple panels on ships?

The bases are better because:
- Economy of scale (single 200-400kt panel can produce more than the equivalent tonnage of small panels.
- Maintenance reduction on the base
- Much bigger than the ships it services, so ships still get maxxed out when the supply base is low on storage.
- No tonnage wasted on engines.

Note:
If you use QNP, it will prevent players from using huge ship hulls with 60kt of engines (to keep up with warships) and a base worth of tonnage for supplies.
