What Happens When Your Commercial Solar O&M Contractor Disappears
Landon Raster
President, RCH Renewables
When your commercial solar O&M contractor disappears, five things break: monitoring access, performance reporting, emergency response, planned maintenance, and warranty claims. Here is what each failure costs and how to avoid it.
SunPower filed Chapter 11 bankruptcy on August 5, 2024. If your commercial solar system was installed by SunPower or one of their authorized California dealers, you already know what follows. Monitoring portals go dark. Service calls go unreturned. The O&M contract you signed becomes a piece of paper with no one on the other end.
That scenario is not unique to SunPower. Solar companies have been consolidating, pivoting, and shutting down for a decade. What is different now is scale. SunPower was one of the largest solar installers in the country. Their exit affected hundreds of thousands of customers on systems that still have 15 to 25 years of expected life.
I am Landon Raster, president of RCH Renewables, C-10 license #1108682, based in Fallbrook. We hold commercial solar O&M contracts with clients including national retail chains across San Diego County and the Central Valley. We service systems we did not install. This post is a practical guide for the facility manager or CFO whose O&M provider has disappeared, is about to disappear, or is simply not performing.
What actually happened with SunPower
SunPower Corporation filed Chapter 11 on August 5, 2024. At that point, they were one of the most recognized solar brands in the country, with a large residential installation network and master dealers across California, including San Diego-area companies.
The timeline of their unraveling is worth understanding, because it illustrates how commercial customers can get caught in transitions they had nothing to do with. In 2022, SunPower sold its entire commercial and industrial O&M business to TotalEnergies for $250 million, choosing to refocus exclusively on residential solar. That sale meant any commercial customers who had SunPower O&M contracts were already being handed off to a different entity before the bankruptcy ever happened.
When the August 2024 bankruptcy hit, the impact fell hardest on residential customers and the residential dealer network. But the pattern of a company reorganizing, selling off divisions, and leaving customers in limbo is exactly what commercial operators need to plan for when choosing an O&M provider.
- Customer-facing support lines were shut down or went unstaffed
- The mySunPower monitoring platform was shut down entirely on September 20, 2024. The app, the web portal, and the support phone line all went dark simultaneously.
- Existing service contracts were effectively voided. A bankrupt entity cannot perform service obligations.
- Warranty claims became difficult to process because the claims pathway through SunPower no longer functioned
- Monitoring and lease assets were eventually acquired by SunStrong Management for $11.5 million; residential dealer assets went to Complete Solaria for $45 million
What breaks when your commercial solar O&M contractor disappears
Not everything breaks immediately. But here is what degrades and how fast.
Monitoring access
ImmediateIf your O&M provider managed the inverter communication setup or monitoring portal, you may lose visibility into system performance. Degradation, inverter faults, and panel-level failures go undetected.
Performance reporting
ImmediateMonthly KPI reports stop. No uptime percentage, no performance ratio, no MTTR, no open ticket log. If your sustainability team needs regular production data, this becomes a compliance problem.
Emergency response
ImmediateAn inverter goes down at 2 PM on a Tuesday. With a real O&M contract, you have a tech on site within one business day and a parts ETA the same day. Without a provider, that is your facilities team scrambling to find someone who services a brand they did not install.
Planned maintenance
Within monthsAnnual system inspections, IV curve tracing, and thermography scans do not happen. Degrading panels and loose connections compound over time with no one catching them.
Warranty claims
Within monthsEquipment manufacturer warranties survive the installer's bankruptcy. But getting a warranty repair done requires a qualified technician and paperwork routed through the manufacturer. Without a service relationship, this becomes ad hoc every time something fails.
The real cost of an unmonitored commercial system
A 100 kW commercial system in SDG&E territory produces roughly 140,000 to 160,000 kWh per year, depending on shading, orientation, and equipment age. At a blended commercial rate of $0.27/kWh, that is approximately $38,000 to $43,000 per year in energy value.
A 10% decline in performance ratio on a 100 kW commercial system represents $3,800 to $4,300 per year in lost production value in SDG&E territory.
On a 200 kW system, that doubles to $7,600 to $8,600 per year in lost production. A single undetected inverter failure on a string inverter configuration can idle 20% to 50% of the array depending on how the system was designed. If it sits undetected for three months, that is a material loss on a capital asset that is supposed to be paying back over 10 to 20 years.
The best O&M contracts are not a cost. They are insurance on a capital investment.
The vetting checklist for a new commercial O&M provider
These are the questions that separate real O&M providers from companies that list maintenance as a service line and do not deliver it.
Do you self-perform field work, or subcontract?
National companies often dispatch the nearest available subcontractor. A local crew in a truck with the company name on it is a different thing. Ask directly. Then ask for proof.
Can I access raw monitoring data, and do I retain ownership of it?
You own the system. You should own the data. Some providers configure monitoring in ways that lock the client out of raw inverter-level data. Confirm you have independent portal access before signing.
What is your average response time for an inverter failure?
Dispatch time and repair completion time are two different things. Inverter replacements often require parts from the manufacturer, and that can take days. A real O&M provider gives you a committed on-site response time AND same-day communication on parts availability. Get both in writing.
Which CMMS platform do you use to track work orders and MTTR?
Mean time to repair is a standard O&M metric. If the provider does not track MTTR or cannot name their CMMS, they are not managing O&M systematically.
What does your monthly KPI report include?
Uptime percentage, performance ratio (PR), MTTR, and open tickets by priority. A report that shows only kWh generated is a generation summary, not an O&M report.
Do you service systems you did not install?
A qualified O&M provider services any inverter brand (SolarEdge, Enphase, SMA, Fronius) regardless of who installed it. Ask which brands they currently service.
Have you ever failed to meet an availability guarantee? Why?
An honest answer is a trust signal. Every provider misses an SLA eventually. The question is whether they track it, report it, and made it right.
What a real commercial O&M contract should include
There is no industry-standard format, which is why buyers get surprised by what is and is not covered. A complete contract includes all of the following.
For inverter failures, get two numbers in writing: on-site response time and how parts ETAs are communicated. The repair itself depends on parts availability. Any contract that only quotes a single response window is not covering the full picture.

If your O&M provider has disappeared, the process starts with a paid site assessment: full system inspection, performance review against original design, and a written findings report. We document all equipment, verify system operation status, and confer with manufacturers on recommended maintenance procedures. Assessment cost is credited toward any O&M contract signed within 30 days.
For more on what commercial O&M contracts look like at RCH, see our commercial solar O&M services page. For companies considering a new commercial solar installation alongside an O&M agreement, see our commercial solar installation page.
A healthy commercial solar system runs at 75% to 85% performance ratio. If yours has dropped below 70% with no active O&M provider, a site assessment will tell you why.
Commercial solar O&M, the questions we hear most
My O&M contractor went out of business. What should I do first?
Confirm you still have independent access to your monitoring portal. If not, contact the inverter manufacturer directly (Enphase, SolarEdge, SMA, or Fronius) to transfer monitoring access to your account. Then pull a 12-month production history to establish whether your system has been underperforming. That gives you a baseline before you bring a new provider in for a site assessment.
Do manufacturer warranties survive if my solar installer goes bankrupt?
Yes. Equipment warranties are between the system owner and the manufacturer, not between the owner and the installer. SunPower's bankruptcy did not void panel or inverter manufacturer warranties. What it voided was the installer's workmanship warranty and service contract. Manufacturer warranty claims still require a qualified technician to submit and fulfill. That is where a new O&M provider helps.
Does RCH service solar systems it did not install?
Yes. We take on existing systems for O&M regardless of original installer. Before starting a service relationship, we do a site walkthrough and condition assessment to document current state and identify any deferred maintenance. That assessment is the foundation for our service scope.
What SLA should I expect from a commercial solar O&M provider?
Emergency response (all-systems loss): same-day dispatch. Critical fault (inverter failure): on-site within 1 business day; parts ETA communicated same day as diagnosis. Standard maintenance and non-critical faults: 3 to 5 business days. Inverter replacements often require parts from the manufacturer. Any provider quoting a single 4-hour repair window for an inverter swap is not being straight with you.
What is a performance ratio (PR) and why does it matter?
Performance ratio is the actual output of your system divided by the theoretical maximum, accounting for weather and irradiance. A healthy commercial system runs at 75% to 85% PR. A system below 70% is losing meaningful production value, typically from dirty panels, undetected shading changes, or a string fault that monitoring would catch immediately. If your reports show only kWh and not PR, you cannot tell the difference between a good system and a degrading one.
How long does it take to transition to a new commercial O&M provider?
For a system in known-good condition, two to four weeks: site walkthrough, condition assessment, contract finalization, and monitoring setup. For a system coming out of an unmonitored period, add time for any deferred maintenance found during assessment. The faster you start the process, the shorter the gap in coverage.
Need an O&M assessment on your commercial system?
Start with a paid site assessment: $175 truck roll + $200/hr per tech, two-tech minimum. Includes full system inspection, performance review against original design, and a written findings report. Assessment cost is credited toward any O&M contract signed within 30 days.
