The short answer
If your original solar installer has closed, identify the equipment manufacturers and current system owner, open a support case through the appropriate official channels, and hire a replacement provider for a defined diagnostic scope. Keep the component warranty, installation contract, monitoring access, and repair charges separate. A company closure alone does not establish which parts are covered or who will pay for the next visit.
SolarEdge tells owners in this situation to review their warranty and find a new installer; it says certain components may still be covered after the installer ceases operations. DOE also advises identifying the panel and inverter manufacturers and asking local installers familiar with those makes about inspection. These are useful starting routes, not a promise that a manufacturer will take over every obligation of the former contractor. SolarEdge installer-closure guidance, DOE guide to an existing solar home
If there is smoke, fire, arcing, or another immediate threat, move away and contact emergency services. For observed damage without an active emergency, keep away from the equipment and contact qualified solar or electrical service. Do not attempt roof work, open equipment, or repeatedly reset a fault while searching for a new provider. DOE warns against untrained people touching PV electrical components even when presumed de-energized. DOE PV System Owner's Guide
Establish who owns the system and who is accepting service requests
Start with the purchase or lease agreement and the latest service correspondence. Is the system owned by you, leased, or under another provider's contract? Record the legal company names from the documents rather than relying on a familiar brand on the old website.
If a closure notice names a successor or service company, verify that information through the equipment manufacturer, contract provider, or other official records relevant to the agreement. Ask the proposed successor which responsibilities it has accepted for your installation. A statement that it “services former customers” does not answer whether it assumed an installation warranty or will merely offer paid repairs.
For a leased or otherwise third-party-owned system, ask the owner who may authorize inspections, access equipment, and approve changes. For financing, lease-payment, contract-enforcement, or bankruptcy questions, obtain an answer from the responsible provider and qualified legal advice when needed. A service technician's opinion should not decide your contract obligations.
If you cannot establish a successor, move forward with manufacturer support and an independent service search. You can preserve a claim or contract question while arranging the safety and diagnostic work that the system needs.
Build a service file before calling several contractors
Gather the installation agreement, invoice, permits and inspection records, utility interconnection documents, array layout, one-line diagram, equipment schedule, warranties, commissioning report, and service history. Identify the inverter, gateway, panels, optimizers or microinverters, and battery from paperwork or safely visible labels. Do not open an enclosure or climb onto the roof to retrieve a serial number.
Save your monitoring site identifier, error text, last-reporting timestamp, and selected production records. Explain the current complaint in one sentence: monitoring is offline, one device has lower output, the inverter has repeated faults, or storm damage is visible. This keeps the inquiry about a specific service need instead of inviting a vague whole-system replacement pitch.
If documents are missing, ask the manufacturer, utility, permitting office, or prior owner which records they actually hold. Mark a record as unavailable instead of reconstructing a diagram from memory. Give the new technician a list of missing information so the diagnostic scope can account for it.
Keep case numbers and responses from each organization in the same file. If the component manufacturer needs a contractor to submit a claim, ask for that requirement in writing and share it with the candidate service provider.
Open the manufacturer case before authorizing covered-part work
Contact the manufacturer through its official support page and describe both the fault and the original installer's closure. Ask which warranty document applies to this product, installation date, location, and ownership history. Ask what evidence is needed to decide coverage and whether the manufacturer requires approval before removal or replacement.
Separate the questions:
- Is the identified component eligible for a warranty claim?
- Which diagnostic evidence is required, and who is allowed to submit it?
- Must a return or replacement authorization be issued first?
- Who handles shipping, failed-part return, and tracking?
- Which labor or service charges are covered by any applicable program or contract?
- What happens if the visit finds a different component or an installation problem?
Do not translate “the part is under warranty” into “the repair is free.” Ask the manufacturer and contractor to identify the actual covered charges and exclusions for your case. If the support response is conditional, retain the condition rather than telling the contractor coverage has already been approved.
Avoid relying on an old warranty PDF for another product generation or country. Use it as a clue only; have the manufacturer confirm the applicable terms. The same caution applies to a paid service plan advertised today: establish whether you already have it, whether this system and fault are eligible, and what any new agreement would cover before buying.
Find a contractor who will service the existing equipment
Ask candidates directly whether they diagnose and repair systems installed by another company and whether they support the actual makes and models. A business that mainly sells new installations may not offer the service you need.
Use manufacturer service directories as a starting point, then independently verify the business identity, applicable license, insurance, and service scope. Ask who will perform electrical and roof-access work and whether subcontractors are involved. Do not assume a directory listing establishes every qualification or a promise of warranty reimbursement.
Request an initial diagnostic quote that states what the visit includes, the charge, the expected report, and how additional work will be authorized. It should explain whether remote review is available first and whether monitoring access is necessary. If the contractor proposes a full replacement immediately, ask what findings justify it and what alternative repair or compatibility constraints were evaluated.
Ask for separate prices for diagnosis, parts, labor, access equipment, shipping, travel, and any monitoring service. A useful comparison is between defined scopes. Two headline prices mean little if one includes warranty administration and return visits while the other does not.
Transfer monitoring access without sharing your password
The replacement provider may need access to system data to diagnose and maintain the installation. Use the manufacturer's access-management route rather than handing over your owner password. Confirm the company's identity and the access it needs before making a change.
Enphase's maintainer guidance explains that owners can add a registered installer company, designate a current PV system maintainer, and manage company access, including whether the company can view consumption data. Consult the current instructions for your account and agree on the access appropriate to the service relationship. Enphase adding a PV system maintainer
Ask support what to do if the former contractor still controls the site or your account lacks the expected access tools. Obtain the manufacturer's approved ownership or access-resolution process; do not create a false installer identity or attempt to bypass account controls.
Record who now monitors alerts, whether monitoring is included in the repair or charged separately, and how you contact the provider for future faults. Having a company listed in an app should not substitute for a service agreement that both sides understand.
End with a documented repair and a working service route
Before closing the case, request the diagnosis, work performed, affected serial numbers, replacement information, warranty decision, and completion tests. Confirm that the app is associated with the correct installed equipment and that you retain owner access.
If no repair was needed, ask for the supported explanation and any follow-up trigger. If further work remains, list the pending authorization, unavailable part, missing record, or unresolved finding and the organization responsible for the next step. Avoid an open-ended “waiting for manufacturer” status without a case number and a specific request.
Store the new service contact and agreement with the solar and battery maintenance records. If ownership or transfer paperwork is the obstacle rather than a repair diagnosis, the rural solar-home ownership and lien guide describes the documents to review with the appropriate professionals.
The goal is a service arrangement another technician can understand: identified equipment, documented responsibility, justified repairs, clear charges, and a reliable way to report the next problem.
