Before you hire: Solar & Battery
Ask each provider to quote the same scope so you can compare the services, fees and exclusions.
- Compare panel, inverter and battery models and warranties.
- Ask what shading and production assumptions the proposal uses.
- Clarify roof repairs, electrical upgrades and utility approvals.
- Review financing, escalators, service obligations and system ownership.
Questions worth asking

- What happens if the system produces less than estimated?
- Are roof work or future removal and reinstallation included?
What belongs in the written scope?
System design, equipment, production assumptions, roof and electrical work, permits, interconnection, monitoring and payment terms.
