Before getting into the warranty mechanics, it’s worth establishing that this isn’t a theoretical concern. Two of the largest residential solar installers in the country have already collapsed — affecting hundreds of thousands of homeowners across the U.S., including customers in Pennsylvania.

Most homeowners sign solar contracts assuming there’s one warranty covering everything. There isn’t. There are two separate warranties, from two separate sources, with very different levels of protection when an installer closes.

Most solar systems include monitoring software — an app or web portal that shows your daily production, alerts you to panel or inverter issues, and tracks your net metering credits. When homeowners find out their installer closed, monitoring access is often the first thing to disappear.

Here’s why: many installers set up monitoring through their own company account, acting as the administrator. When that company winds down its systems, customer access can go dark — even though the underlying hardware is still working fine.

The fix exists, and it’s straightforward. The two most common inverter platforms — Enphase and SolarEdge — both have processes for transferring monitoring ownership directly to a homeowner account. Don’t wait until there’s a problem. Do this now, while you still have your original login credentials and installer contact information.

Monitoring matters beyond convenience. A single failed microinverter typically costs $50–$100 per year in lost production and SREC income. Without monitoring, that failure can go undetected for months or years. With monitoring transferred to your own account, you’ll see a production drop within 24–48 hours of any panel or inverter issue.

If you purchased or financed your solar system, you own the equipment. The manufacturer warranties described above apply to you directly, and your situation — while not ideal if your installer closes — is more straightforward.

If you leased your system or entered a Power Purchase Agreement (PPA), the situation is meaningfully different. The company that installed your panels still owns them. When that company goes bankrupt, your lease or PPA becomes an asset in the bankruptcy estate — and it typically gets acquired by another company.

In the SunPower bankruptcy, residential lease and PPA contracts were transferred to a company called SunStrong Capital. SunPower customers didn’t lose their contracts — but they did gain a new servicer they’d never dealt with, with potentially different service response times, different app access, and different processes for maintenance requests.

You don’t need to wait for a problem to take these steps. If you already have solar panels installed, running through this checklist now takes about an hour and makes you significantly more protected if something changes later.

If you’re still in the research phase, these are the questions that matter for installer-closure protection. A reputable installer will answer all of them directly. Evasive answers are information.

Solar installer bankruptcies are not hypothetical — they’ve happened at scale, and they’ve left homeowners with real gaps in warranty coverage and service access. Understanding the difference between equipment warranties (which survive installer closure, as long as the manufacturer is around) and workmanship warranties (which typically don’t) is the single most important thing a solar homeowner can know.

The steps above don’t require anything from your installer. Transfer your monitoring, register your equipment directly, and save your documents somewhere you control. That’s most of the protection available to you — and it takes an afternoon.
