Questions to Ask a Solar Installer
Worth asking every provider you talk to, so you’re comparing apples to apples.
Credentials
- Are you licensed to do electrical/solar installation work in Indiana? Can I see the license number?
- Is your installation crew NABCEP-certified (or equivalent)?
- How long has the company been operating in Indiana specifically?
Pricing and utility rate
- What’s the total system price, in writing, broken out by equipment and labor?
- Which utility serves my address, and what is its current EDG or feed-in tariff rate? (See Net Metering & EDG — the rate is very different depending on whether NIPSCO or one of the other four utilities serves you.)
- What does the price look like with my actual financing option — not a generic “with incentives” number? (See Incentives & Tax Credits — the federal credit rules changed for 2026.)
Equipment and warranty
- What panel and inverter brands are you using, and are they Tier 1 equipment?
- What’s the warranty on panels, inverter, and workmanship — separately?
- Who handles a warranty claim if the installer goes out of business?
Process and utility
- Who handles permitting and interconnection with my utility, and what’s the typical timeline?
- How is my system sized given my utility’s export credit rate — is it built to minimize surplus export?
Getting the same answers from more than one provider is the most reliable way to spot inconsistent or inflated claims.
