Questions to Ask Installersπ€
Must-Ask Questions
- "What's the total installed price, no hidden fees?"
- "Does this include backup capability during blackouts?"
- "What's the warranty and who handles claims?"
- "Can I expand this later if I get an EV?"
Red Flags
- Pressure to sign today for a "limited" discount
- Unrealistic payback claims (under 5 years = sus)
- Can't explain who handles warranty issues
- No CEC accreditation or insurance proof
