Watt Masters can inspect, troubleshoot, and repair many existing SunPower solar systems in Arizona, including systems installed by another contractor.
The first step is identifying your particular equipment and determining what’s actually causing the problem.
That distinction matters because a “SunPower system” can include several components, and the service path can depend on when the system was installed, who installed it, how it was purchased or financed, and what equipment is actually on the home.
Watt Masters has served Arizona since 1999 as an electrical contractor with extensive solar experience.
We’re not here to sell you another solar system simply because the company situation changed.
You already have solar. Our job is to find out why it isn’t working correctly.
Watt Masters can service and troubleshoot existing Titan Solar Power systems in Arizona. Titan Solar Power filed for Chapter 7 bankruptcy in 2024 and is no longer operating. Former Titan customers who need repairs can hire an independent qualified solar and electrical contractor to diagnose and service their existing equipment.
Serving Arizona for more than 25 years.
Solar troubleshooting beyond the panels
We work on solar installed by other companies
There’s quite a bit of confusion around this question.
The original SunPower Corporation filed for Chapter 11 bankruptcy on August 5, 2024.
During the bankruptcy process, Complete Solar acquired certain SunPower assets. That transaction closed on September 30, 2024 and included assets associated with businesses such as Blue Raven Solar, New Homes, and the non-installing dealer network, along with the SunPower brand and intellectual property.
Complete Solar subsequently adopted the SunPower name.
So there is a company operating under the SunPower name today.
But that doesn’t mean every older SunPower customer’s system, warranty, lease, PPA, or service obligation simply transferred to the new company.
That’s where the installation date becomes important.
This is one of the most useful things for a legacy SunPower customer to know.
The current SunPower organization states that its acquisition of selected assets from the former SunPower Corporation did not include interests in customer PPAs, leases, solar systems, batteries, or other equipment installed on or before September 30, 2024.
That can leave owners of older SunPower systems unsure where to turn when something fails.
If your older system needs actual solar or electrical service, Watt Masters can help evaluate the equipment and determine what’s happening.
A system that suddenly stops producing doesn’t necessarily need to be replaced.
The problem could be relatively isolated.
Depending on the system and equipment, possible causes can include:
If your SunPower system is showing an error, isn’t producing, or has unexpectedly dropped in output, the power electronics are one area that may need to be investigated.
Different generations of SunPower systems can use different system architectures and equipment.
That’s why “SunPower inverter repair” isn’t always as simple as ordering a particular inverter based on the SunPower name.
The technician needs to identify what’s actually installed.
Don’t assume a dead-looking SolarEdge system means the entire solar array has failed.
The panels may still be perfectly usable.
Watt Masters Does Not Assume SunPower Warranties
Watt Masters is an independent contractor.
We don’t assume the warranty, contractual, financial, or other obligations of the former SunPower Corporation or current SunPower Inc.
What we can do is diagnose the system, identify the equipment involved, and give you a clearer understanding of what has failed and what the repair may require.
This requires a more careful answer than simply saying yes or no.
SunPower systems can involve several different types of warranties and contractual relationships.
Legacy SunPower Workmanship or Service Coverage
If your warranty or service obligation came directly from the former SunPower Corporation, the company’s bankruptcy and subsequent asset sale may affect that coverage.
The current SunPower organization specifically distinguishes older installations from systems installed after its September 30, 2024 acquisition.
Manufacturer Warranties
Individual components may also have manufacturer warranty coverage.
Whether coverage remains available depends on the particular product, installation date, manufacturer, warranty terms, cause of failure, ownership history, and other requirements.
Some older SunPower systems use the company’s well-known high-efficiency solar panels.
There’s another distinction worth understanding here.
SunPower Corporation and Maxeon Solar Technologies became separate companies in 2020. Maxeon continued manufacturing SunPower-branded panels for a period following that separation.
As a result, the company name on your original solar contract doesn’t necessarily tell you who manufactured or warrants every component on the roof today.
If you’re trying to determine warranty eligibility for an existing panel, start with the actual equipment.
Useful information can include:
We'll determine whether the issue involves the inverter, microinverters, electrical equipment, wiring, communications, or another component.
A significant unexplained production decrease deserves investigation, particularly when your electrical usage hasn't changed.
We'll identify the equipment and troubleshoot the fault rather than assuming every error requires complete replacement.
We'll help distinguish between a monitoring problem and an actual production problem.
Solar systems contain breakers, conductors, connections, disconnects, grounding, and other electrical infrastructure that can develop faults.
This is where having an experienced electrical contractor matters.
Need to replace the roof under an existing SunPower array? Watt Masters provides solar panel removal and reinstallation for roofing projects.
Phoenix heat, monsoon winds, dust, and severe weather can expose problems with older solar equipment, wiring, attachments, and roofing.
If you inherited an older SunPower system or aren't confident that yours is operating correctly, an inspection can establish what equipment you have and whether the system is functioning as expected.
You don’t need someone to sell you solar. You already have it.
You need someone who understands how to troubleshoot the system that’s already installed.
Watt Masters has served Arizona since 1999 as an electrical contractor with solar expertise.
That means we look beyond the panels.
Depending on the problem, we can evaluate:
And because we service existing systems, Watt Masters can work on solar we didn’t originally install.
That’s particularly valuable for homeowners caught between an old installer, a manufacturer, a financing company, and a system that simply needs to work again.
Watt Masters provides independent solar troubleshooting and repair for existing systems throughout our Arizona service area.
If you’re searching for:
you don’t necessarily need another solar sales company.
You need someone who can diagnose the equipment you already own.
If possible, gather:
Don’t have any of it?
That’s okay.
We can start with what you know.
The former SunPower Corporation filed for Chapter 11 bankruptcy in August 2024. Complete Solar subsequently purchased certain SunPower assets, including the SunPower brand, and the resulting company now operates as SunPower Inc. It is therefore more accurate to distinguish the former SunPower Corporation from the company operating under the SunPower name today.
Not necessarily. The current SunPower states that its acquisition did not include interests in solar systems, batteries, PPAs, or leases installed on or before September 30, 2024. Your individual situation depends on your installation, agreement, equipment, and financing arrangement.
Independent qualified solar and electrical contractors may be able to service legacy SunPower systems. Watt Masters provides troubleshooting and repair for existing Arizona solar systems, including systems installed by other companies.
No. Watt Masters is an independent Arizona electrical and solar contractor and is not affiliated with or endorsed by SunPower Corporation or SunPower Inc.
Yes. Watt Masters services and troubleshoots existing solar systems installed by other contractors.
Not necessarily. Inverter or microinverter problems, electrical faults, breakers, wiring, communications, and other components can stop a system from producing even when the solar modules remain functional.
We can investigate whether a monitoring issue is related to communications, system operation, electrical equipment, or another serviceable problem. Access and restoration options depend on the particular equipment and platform.
Possibly, but warranty coverage depends on the particular panel, manufacturer, installation date, original warranty terms, ownership history, and nature of the failure. The former SunPower Corporation’s bankruptcy also complicates some legacy warranty obligations.
Don’t assume that it does. Financing agreements are generally separate contractual obligations. Contact the lender or appropriate contractual party regarding your specific financing situation.
Legacy SunPower leases and PPAs may involve separate financing or management entities. Review your agreement and contact the appropriate organization for contractual questions. Watt Masters can help with independent solar and electrical service when appropriate.
Yes. Watt Masters provides solar panel removal and reinstallation for roof replacement projects, including existing systems installed by other contractors.
Yes. If you inherited an existing solar system with a home purchase, Watt Masters can inspect and troubleshoot the system and help identify the installed equipment.
