Orphaned systems
What Happens When the Original Solar Installer Is Out of Business?
Workmanship warranties die with the company. Equipment warranties usually don't.
Split the warranties. The workmanship warranty — covering the installation itself, roof penetrations, wiring and labour — is typically issued by the installer, and it generally dies with the company. The equipment warranties on modules and inverters are issued by the manufacturers and usually survive, though claiming on them without an installer to do the labour becomes the owner's problem.
This is common, not unusual
California’s residential solar industry has seen substantial consolidation and a number of failures, including large national installers. A system installed a decade ago has a meaningful chance of being orphaned — the equipment is fine, but the company that put it up no longer answers the phone.
You can check whether a contractor’s licence is still active through the Contractors State License Board. A cancelled or expired licence is a strong signal, though not proof, that workmanship coverage is gone.
What survives and what doesn’t
- Module warranty. Manufacturer-issued, typically long-dated for both product and performance. Usually survives.
- Inverter warranty. Manufacturer-issued. Usually survives, and manufacturers generally have their own service processes.
- Module-level electronics. Manufacturer-issued, and often the practical route to replacing a failed unit.
- Workmanship / installation warranty. Installer-issued. Generally does not survive the company.
- Roof penetration warranty. Usually part of workmanship, and the one that hurts, because water intrusion under an array is expensive.
What it means for a transaction
It doesn’t make the house unsellable, and it doesn’t make the system bad. What it changes is who carries the risk of an installation defect, and that is worth establishing before contingencies come off rather than after.
It also raises the value of an actual inspection. When there’s no installer to fall back on, the condition of the mounting, the penetrations and the conductor management stops being a warranty question and starts being a buyer’s question.
Practical steps
- Check the installer’s licence status with the CSLB.
- Locate the module and inverter manufacturers, and confirm the warranty terms directly with them.
- Get the system inspected, with particular attention to mounting, penetrations and wire management.
- Establish who will do future service work — many manufacturers maintain networks of servicing companies independent of the original installer.
If the system is leased or on a PPA, the installer going out of business is a separate question from who services the agreement — those are frequently different companies, and in several cases the agreement has changed hands since.
