Solar Panels After Hail: Choose an Inspection Before Approving Replacement

The short answer

After hail hits a home with solar panels, keep people away from damaged equipment, save what you can observe safely, and contact a qualified solar service provider. The first decision is whether the system needs to be made safe immediately. The next is what inspection can establish the condition of the modules, electrical equipment, mounting, and roof. A normal-looking app or an intact-looking panel does not settle every post-storm question.

DOE's hail guidance explains that hail can crack solar cells without breaking the glass and identifies professional imaging as one way to investigate hidden damage. Its weather-vulnerability guide warns that storm-damaged electrical components can energize unexpected surfaces and that a qualified electrician or technician must establish safety before field inspection. Do not climb onto the roof, touch fragments, approach hanging wires, or operate unfamiliar shutdown controls. For smoke, fire, arcing, or another immediate threat, move away and contact emergency services. For observed damage without an active emergency, keep away and contact qualified solar or electrical service. DOE hail damage mitigation, DOE PV System Owner's Guide

Separate an emergency from an inspection appointment

Smoke, arcing, a burning smell, loose equipment threatening to fall, or damaged wires calls for immediate emergency or qualified safety help. Move people and pets away from the affected area. Tell responders the property has solar and whether it has battery storage. Do not stand below damaged roof-mounted equipment to get a better photograph.

If there is no immediate dangerous condition apparent from a safe location, contact the solar provider about a post-hail assessment. Describe exactly what you can see and which app alerts appeared. Ask who will determine whether the equipment may remain in service or needs professional isolation. A roof contractor's general assessment should not be treated as an electrical clearance unless that work is explicitly within the person's qualifications and scope.

If the installation is leased or belongs to another provider, notify that owner through the contract's service route as well. Ask who authorizes inspection and repairs. Keep that responsibility question separate from whether your household insurer may cover any part of the loss.

Preserve evidence without creating another hazard

Record the storm date and approximate time, the first alert, and any visible change. Save app screenshots showing the date range and last update. Retain earlier production records and any pre-storm inspection photographs you already have.

From a safe ground-level location, take an overall photograph of the affected roof or ground-mounted array and any visible displaced equipment or broken glass. Include context rather than only a zoomed-in mark. If the equipment is hidden from a safe location, write “not visible from the ground.” That is more useful than assuming it is undamaged.

The National Association of Insurance Commissioners recommends documenting storm losses before cleanup, contacting the insurer promptly, and retaining receipts. Apply that advice safely: ask professionals to document removed solar components and follow the insurer's instructions about inspection and retention. Do not keep or handle a hazardous electrical component yourself. NAIC after-storm claims guidance

Contact your insurer or agent to ask about the applicable reporting process, inspection authorization, deductible, and coverage for the actual installation. Do not rely on a contractor's assurance that “insurance pays for all solar hail damage.” Ask whether rooftop and ground-mounted equipment, third-party-owned equipment, removal for roof work, and reinstallation are addressed by your policy and contracts. Those are questions for this loss, not a nationwide coverage rule.

Decide what the inspection needs to answer

Ask for a scope that separates four findings: visible module damage, hidden cell or electrical problems, mounting damage, and roof damage. A photograph of broken glass supports a visible-damage finding. It does not, by itself, describe the condition of all neighboring modules, their wiring, or the roof underneath.

A useful inspection report identifies each examined component, its position or serial number, the observation or measurement, and any inaccessible area. It should state what was inspected visually, what was tested electrically, and what imaging was performed. Ask what conclusion each part supports.

If there is obvious damage, request a prompt professional safety assessment and a repair plan. If no damage is obvious but the array took a significant hail impact or production has changed, ask whether additional testing or imaging is justified. If the inspector proposes only a visual survey, ask which hidden-damage questions will remain unanswered and what would trigger a follow-up.

DOE's hail guidance describes infrared, ultraviolet fluorescence, and electroluminescence imaging, and notes that comparing post-event results with a baseline can help identify event-related damage. It also notes that hail patterns can be random. Ask the professional to explain the planned coverage of the array instead of assuming the most visible impact represents every panel.

Ask why a particular imaging test is proposed

You do not need to become an imaging specialist to review a quote. Ask the contractor what question the proposed test answers and how its result will change the repair decision.

For example, is the goal to locate an unusual temperature pattern, investigate suspected cell cracks, document damage for the manufacturer, or compare suspected damage with earlier records? Request a report that identifies the tested modules and explains the findings. An image without interpretation is not a repair recommendation.

DOE describes electroluminescence imaging as useful for revealing cell cracks, with more time and cost involved than some other screening methods. Its weather-vulnerability guide calls for skilled imaging professionals to interpret results. These are professional tests; do not attempt to reproduce them by connecting equipment, energizing circuits, or manipulating roof panels. DOE hail damage mitigation, DOE PV System Owner's Guide

Avoid both sweeping conclusions: “all cracked cells will rapidly fail” and “if power is normal, every module is fine.” A laboratory field study of hail-exposed modules in Golden, Colorado found differing initial power losses but did not find an increased degradation rate over its subsequent observation period. That result concerns those tested modules and conditions; it does not predict the outcome for your roof. Have the inspector explain the safety and performance significance of the actual findings.

Require a repair scope tied to identified damage

Before approving a few replacement panels or a complete array replacement, ask for the component-level findings supporting that scope. If replacement of undamaged-looking modules is proposed, ask whether the reason is a documented fault, a compatibility issue, a manufacturer requirement, or another stated constraint.

The written proposal should identify:

Modules and other components to repair or replace, with locations and findings
The proposed replacement models and documented compatibility with the system
Qualified responsibility for electrical work, safe access, and roof work
What removal and reinstallation includes if the roof also needs repair
Relevant warranty and insurer decisions, with parts and labor charges separated
Required local approvals or utility involvement, if applicable to the actual changes
The tests and commissioning records that will support return to service

If the solar and roof contractors are separate, ask them to agree on the work sequence before either begins. Who removes and stores equipment, protects the roof, replaces attachments, reconnects the system, and checks the finished installation? Put those responsibilities in the scopes rather than accepting an informal promise that the other contractor will handle them.

Ask how removed equipment will be photographed, identified, retained if required for a claim, and handled afterward. Do not authorize disposal until the responsible provider and insurer have answered their evidence needs, unless safety requires a professional to act immediately.

Close the repair with two separate records

Request a safety and service-completion record from the qualified contractor and a separate explanation of the post-repair performance check. Keep the inspection findings, images, component identifiers, warranty or claim decisions, approvals, and final invoices together.

Ask the technician what future data or visible change would require another visit if some modules remain in place under a monitoring plan. The plan should identify the concern, comparison period or test, responsible reviewer, and escalation trigger. “No visible damage today” should not quietly become a guarantee against future trouble.

After work involving the roof, retain the roofing completion record as well as the solar commissioning report. Neither contractor's invoice substitutes for the other's findings. Update the array layout and equipment schedule if anything changed.
