energy Building Comparison
Fusion Reactor vs Solar Power Plant
Comparing the Fusion Reactor and Solar Power Plant, both energy buildings in Starforge MMO. Base plots and energy upkeep are scarce, so use this to decide which structure earns its slot first.
Build & Output Comparison
| Attribute | Fusion Reactor | Solar Power Plant |
|---|---|---|
| Max level | 10 | 15 |
| Base cost | 2,000 metal, 1,500 crystal | 200 metal, 150 crystal |
| Upkeep | 20 gas, 10 crystal | 5 metal |
| energy output / level | +300★ | +50 |
★ marks the higher per-level output. Compare against your base's current bottleneck before committing a plot.
Fusion Reactor
High-output fusion core. Powers entire fleets of ships.
Requires tech: energy 2
Requires building: solar plant
Solar Power Plant
Converts star radiation to usable energy. Powers other buildings.
Which Should You Build First?
Both are energy buildings, so the choice depends on your current bottleneck. Prioritise the structure whose highlighted per-level output addresses your scarcest resource, and weigh that against its energy upkeep — a high output that drains your power grid can stall the rest of your base.
