Path-Q Solar
When should I obtain an independent electrical inspection before accepting a solar quote?
Answer
Consider an independent inspection before accepting a quote when the existing service, wiring, grounding, roof equipment, prior work, or available capacity is uncertain, or when proposals make conflicting assumptions. It is especially useful when the project includes a service upgrade, battery, complex interconnection, or an older or modified electrical system.
Key points
- An inspection can identify conditions that change scope before you sign a contract.
- It should assess the relevant existing equipment and not be treated as a substitute for the installer's design responsibility.
- Ask for written findings, photographs, limitations, and any recommended corrective work.
What it depends on
- Age and condition of the electrical service
- Planned system size and equipment
- Evidence of previous alterations or defects
- Differences among installer assumptions
Risks and trade-offs
- Inspection adds time and cost but may reduce change orders and safety surprises.
- An inspector's limited visual review may not reveal concealed defects.
Information you may need
- Existing electrical panel and service information
- Proposed system one-line diagrams
- Installer scope and assumptions
- Records of prior electrical work or inspections
Your next step
What to do next
Request each installer to state its assumptions about existing capacity, then arrange an independent inspection if those assumptions cannot be verified from records or a site review.
