A ZIP code is a starting point for location, not an assessment of your roof. Shading, roof condition, usable space, and household needs all belong in the conversation.
Prepare a small project folder.
- Roof information: age, material, known repairs, and any planned replacement.
- Shading observations: trees, nearby structures, and areas shaded at different times.
- Electricity use: recent bills and changes you expect in the coming year.
- Existing equipment: solar, battery, generator, or EV charging documentation.
- Your priorities: daytime generation, backup, or both.
Keep estimates separate from approvals.
A solar production model is an estimate. A qualified assessment still needs to address the property, installation requirements, and the utility’s process. Ask which assumptions are included and what remains to be checked.
Useful next question: “What would make this property unsuitable, or change the proposed system?” Ask it before committing to equipment.
