Comparing solar options with the same assumptions
An option comparison becomes confusing when the underlying usage or rate assumptions change between columns.
A practical approach
Ask the proposal reviewer to show a consistent baseline and explain intentional differences. Keep equipment, scope and payment terms visible so the homeowner understands what drives the result. Do not compare only a favorable monthly figure from one option with a total cost from another. Use the approved comparison materials.
Put it into practice
- Use a consistent baseline
- Explain intentional differences
- Compare like-for-like figures
