Solar Installer Closed? How to Arrange Repairs or Add a Battery
Build a service handover packet, check ownership and warranties, and request qualified solar repairs or a battery assessment after your installer closes.

Your panels are still on the roof, but the company that installed them has disappeared. Start by establishing ownership, identifying the equipment and asking the manufacturer about service and warranty procedures. Then request a defined diagnostic visit from a qualified contractor. Treat repairs and a battery addition as separate decisions.
The closure does not answer every warranty question
An installer’s workmanship promise, a manufacturer’s equipment warranty, monitoring support and financing are different arrangements. The installer’s disappearance does not establish which other obligations remain enforceable or who will pay for diagnosis, labor, shipping or roof access.
The U.S. Department of Energy recommends identifying the panel and inverter manufacturers when an installer is no longer operating, then asking knowledgeable local installers about inspection. Obtain the actual warranty documents and a case number before assuming that replacement parts or service are covered.
If the equipment belongs to a lease or power-purchase-agreement provider, contact that owner before authorizing alterations. Keep any financing dispute separate from the technical diagnosis.
A Los Angeles County question becomes a service handover
In a public question dated September 14, 2026, a Los Angeles County homeowner said the original installer had closed and asked what a replacement contractor would need to service the system or consider a battery.
The homeowner identified equipment details, monitoring access, permits and interconnection paperwork as possible starting points. The discussion did not provide an independently verified inspection, equipment inventory or repair diagnosis. It cannot support a repair-price estimate or a conclusion that a battery will work.
A useful response turns those uncertainties into a handover packet. Each missing document becomes a specific request to the manufacturer, utility, permitting office or system owner—not a reason to guess.
Build the packet before requesting estimates
Use the service handover worksheet below. Begin with the ownership agreement, equipment models and serial numbers, monitoring and fault history, approved plans, permit final, operating approval, warranty documents, claim number, recent bills and historical production.
Request monitoring access through the provider’s official ownership-transfer process. Do not send passwords to companies collecting estimates. Have a qualified professional obtain inaccessible equipment information; do not climb onto the roof or open electrical enclosures.
Request diagnosis before approving replacement
Ask the contractor to identify its diagnostic scope, visit fee, required authorization and deliverable. A useful written finding distinguishes a monitoring failure from an electrical failure and states what was tested, what remains uncertain and what repair is recommended.
Check the contractor’s license and relevant scope through California’s Contractors State License Board. For substantial work, compare written bids. Separate diagnosis, parts, labor, permits and roof work instead of comparing unexplained totals.
A battery needs its own compatibility and utility review
A battery proposal should identify the existing inverter, connection method, backup equipment, supported circuits and equipment compatibility. Ask for usable capacity, continuous output, starting-load capability, reserve settings and an equipment-specific warranty.
A battery addition does not automatically require losing an existing NEM arrangement. SCE’s current FAQ distinguishes an eligible storage-only addition from capacity expansions. Require written confirmation for the proposed design and application pathway; municipal utilities have their own rules.
Ask for two scopes: restoring the existing system and adding storage. That makes it easier to judge whether the battery solves a defined backup or billing need rather than becoming part of an unexplained repair bill.
Send this service request
“My original installer is unavailable. I need a diagnostic assessment of the existing system before deciding on repairs or storage. I can provide the attached ownership, equipment, monitoring and approval records. Please confirm your experience with these models, required authorizations, diagnostic fee, written findings and warranty-claim process. Quote any battery addition separately.”
The immediate goal is a documented diagnosis and a responsible service contact. A larger system, a battery or a new financing agreement should follow evidence of a need.

Frequently asked questions
Does an installer closure cancel every warranty?
The installer’s workmanship promise and manufacturers’ equipment warranties are different arrangements. Read the actual documents and ask the manufacturer about claim procedures, authorized service and parts or labor coverage. Closure alone does not establish all remaining rights or costs.
What should I prepare before contacting a replacement installer?
Prepare ownership documents, equipment model and serial numbers, monitoring and fault history, approved plans, permit and utility approvals, warranty records and recent bills. Request a defined diagnostic scope, fee and written findings before authorizing repairs.
Will adding a battery automatically end my existing NEM arrangement?
Not automatically. SCE distinguishes an eligible storage-only addition from capacity expansions. Have the proposed design and application pathway confirmed in writing by the applicable utility; municipal utilities use their own rules.
