Interviewing Your Solar Professional
When you sit down with a solar installer to review a quote, you need to ask the right questions to ensure they are reputable and that their proposal fits your needs.
Experience and Operations
- How long have you been installing solar in this specific area? Local experience dictates how well they understand local permitting and utility rules.
- Are your installers in-house employees or subcontractors? Subcontractors aren't inherently bad, but in-house crews often provide more consistent quality and accountability.
- What happens if my roof gets damaged during installation? Get their policy in writing.
Equipment and Warranties
- Who manufactures the panels and inverters, and what are their warranties? Distinguish between the manufacturer's equipment warranty and the installer's workmanship warranty.
- Do you offer a production guarantee? Some installers guarantee the system will produce a certain amount of energy, reimbursing you if it falls short.
Timelines and Communication
- Who handles the permitting process? The installer should handle this entirely.
- What is the estimated timeline from contract signing to "Permission to Operate" (PTO)? Knowing this manages expectations regarding utility delays.
