Clear answer
Clear answer, explained.
Smaller buildings may install systems in the 50–200 kW range, while large arenas, transit depots, or multi-use complexes can support systems of several hundred kilowatts or more. Final system size is determined by usable roof space, structural capacity, electrical service limits, and utility interconnection rules.
Key points
What this means in practice.
- Small municipal buildings: ~50–200 kW Medium facilities (libraries, offices, schools): ~200–500 kW Large facilities (arenas, depots, water plants): ~500 kW–1
- MW+ Roof area and structural limits define maximum capacity
- Daytime load profile influences optimal sizing
- Utility interconnection limits may cap system size
When this applies
Best-fit environments.
- City halls, libraries, community centres, and fire stations
- Recreation complexes, arenas, and transit facilities
- Water and wastewater treatment plants
- Municipal portfolio solar planning programs
