Bankrupt solar installer office

You got three quotes: $32,000, $30,000, and $24,000.

The last one was from "Bob's Solar Shack." Bob seemed nice. He promised the same equipment as the big guys but with way less overhead. You went with Bob.

Three years later, your inverter flashes a red light. The system is dead. You call Bob. "The number you have reached is no longer in service."

Bob went bankrupt. Or he retired. Or he pivoted to selling pool supplies. Now you have a 25-year warranty from a ghost.

The Trap Solar is a boom-and-bust industry. We call them "Truck Slammers"—guys who form an LLC, slam installs for two years to grab the cash, and dissolve the company when the service calls start rolling in.

The Fix: Manufacturer vs. Workmanship You need to understand the two types of warranties. 1. Workmanship: This covers the labor (leaks, loose wires). This is held by Bob. If Bob dies, this warranty dies. 2. Equipment: This covers the hardware (panels, inverters). This is held by the manufacturer (Enphase, Tesla, REC).

If you bought tier-1 equipment, you are okay. If Bob installed generic junk, you are in trouble.

Pro Tip From the Field "Don't just check Yelp reviews; check the license history. In California, I look up the CSLB number. If the license was issued 8 months ago, I run. You want a company that survived the last 'Solar Coaster' crash (around 2016 or 2023).

Also, verify the installer's status with the manufacturer. Go to the Enphase or REC website and use their 'Find an Installer' tool. If Bob isn't listed as a Certified or Platinum installer, it means he buys his gear from a middleman distributor. If he goes bust, the manufacturer might not even have a record of your system. Hire the guy who is Platinum certified; the manufacturer will verify his work and back him up."

FAQ: Orphaned Systems

  • Q: Who do I call if my installer goes out of business?
    • A: You call a solar service company (often called 'Solar Doctors'). You will have to pay for the truck roll and labor ($200-$500), but they can usually process the RMA for the free replacement part from the manufacturer.
  • Q: Is my 25-year labor warranty worthless?
    • A: If the installer is gone, yes. Third-party insurance (like SolarInsure) exists to cover this, but you have to buy it upfront.
  • Q: Can I fix it myself?
    • A: Do not open the inverter. It contains capacitors that can hold a lethal charge even when the power is off. Call a pro."
