Solar Energy Systems: compare the models.
Look at the operating differences before comparing financial projections.
Back to all solar energy systems models| Model | Earns from | Capacity constraints | Key distinction |
|---|---|---|---|
| Customer Solar Supply and Installation | Accepted project or work milestone | Procurement lead times, installation crews and site schedule | The operator bears integrated supply and installation responsibility. |
| Owned Solar Generation with Energy Sales | Externally billed kilowatt-hour | Installed generation capacity, seasonal resource yield, uptime and offtake limits | Asset ownership and metered output revenue differ from equipment sales, installation or management-only service. |
| Customer-System Maintenance Routes | Contract-month or completed route visit | Route density, visit duration and frequency | Repeat visit schedules and geographic routing change capacity and cost structure. |
| Solar EPC Installation Subcontractor | Accepted work unit, milestone or billed hour | Trade crew availability and project access | Contracted scope and material ownership differ from selling a complete turnkey project. |
