Who Insures Solar Panels, and When?
By Seamless Home Team, Solar fulfillment operations · August 24, 2026
Quick answer
Three different parties insure a residential PV solar system at three different stages, and no single policy runs from delivery to end of life. Before and during installation the risk normally sits with the installer or contractor — general liability for damage they cause, and builder's risk or inland marine cover for the equipment itself while it is in transit and on site. After the system is complete and energised, an owned system becomes the homeowner's responsibility and is usually covered as part of the dwelling under a standard homeowner's policy when it is roof-mounted, though ground mounts, batteries and high-value arrays frequently need a scheduled endorsement to be covered at all. A leased or PPA system is insured by the third-party owner, because the third-party owner owns the asset. The two reliable gaps are the handoff at completion, when builder's risk ends before the homeowner's carrier has been told the system exists, and the assumption that a roof-mounted array is automatically covered at replacement cost when many policies settle roof-attached equipment at actual cash value.
A finished array is energised on a Friday. The installer's builder's risk cover lapses on acceptance. The homeowner's carrier has never been told a system was installed, because nobody in the transaction saw that as their job.
A hailstorm arrives eleven days later.
There is no dispute about whether the damage is real, and no dispute about whose property it is. The dispute is about which of two policies was in force, and the honest answer is neither.
A PV solar system passes through three insurance regimes, not one
Nobody insures a residential PV solar system from delivery to end of life. Three different parties carry the risk at three different stages, and each handoff is a place where cover can simply stop.
| Stage | Who normally carries the risk | The instrument | Typical gap |
|---|---|---|---|
| Materials in transit and on site | Supplier, then the buying party | Shipping terms, then inland marine or an installation floater | Risk passes at delivery, not at install |
| Work in progress | Installer or contractor | General liability, plus builder's risk | Excludes the installer's own defective work |
| Complete and energised, owned | Homeowner | Homeowner's dwelling cover, plus endorsements | Carrier was never notified |
| Complete and energised, third-party owned | The lease or PPA provider | The provider's own property cover | Homeowner's liability position unread |
The pattern is the same one that runs through most post-handover disputes on a PV solar project: every individual instrument does what it says, and the losses collect in the seams between them.
Stage one: the equipment is somebody's risk before anyone installs it
Modules and inverters routinely sit for days or weeks between delivery and installation. During that period they are valuable, portable, and outdoors.
The question of who bears a loss then is settled by the shipping terms, not by intuition. Risk of loss commonly passes to the buying party on delivery — which means the pallet on the driveway is already the buyer's risk while it is still, physically, untouched by anyone. A homeowner's policy is generally the wrong place to look: household policies typically exclude property of others and materials awaiting installation, so an array in a garage before install is usually outside it.
What responds instead is contractor-carried cover, written as inland marine, an installation floater, or as part of a builder's risk policy.
Theft is the case that comes up most, and it has its own dynamics — the equipment is identifiable by serial number, which helps recovery and helps a claim, but only if somebody wrote the serial numbers down. Our note on equipment stolen from a job site covers that in detail.
Two specific losses at this stage are worth their own treatment, because responsibility for each is decided by paperwork rather than by fault: what happens when solar materials arrive damaged, and who pays when solar equipment is stolen from a job site.
Stage two: during installation, two different policies do two different jobs
While work is underway, the installer normally carries two things that are easy to conflate.
General liability answers for damage the installer causes to something else — a foot through a ceiling, a penetration that leaks, a fire from a bad termination. It is third-party cover. It does not pay to redo the installer's own faulty work.
Builder's risk answers for damage to the work itself and to materials on site, from perils like fire, wind, and theft. It is first-party cover on the project.
Neither pays for defective workmanship as such. That is what a workmanship warranty is for, and it is a contractual promise rather than an insurance product — a distinction that matters because a warranty is only as good as the entity standing behind it, which is why an installer's insolvency and an installer's warranty are two separate problems. Our note on what happens when an installer goes out of business takes that further.
For a sales organisation routing work to installers, the practical implication is narrower and more useful: verifying that a subcontracted installer actually carries current cover, at adequate limits, with the right parties named, is a vetting step rather than a paperwork step. The installer vetting scorecard treats it that way, and the subcontractor agreement note covers what the agreement should say about it.
Stage three: the handoff at completion, which is the real gap
Builder's risk is temporary by design. It terminates on a trigger, and the triggers are commonly written as the earliest of a stated expiry date, acceptance of the work, or the property being put to its intended use.
Energising a PV solar system is putting it to its intended use.
So cover on the construction side tends to end around the point of permission to operate — the same moment everyone in the transaction is focused on a funding milestone rather than on an insurance handoff. Meanwhile, on the homeowner's side, cover does not switch on by itself. A standard policy insures the dwelling as described to the carrier, and a carrier that was never told about a system has underwritten a house without one.
That produces a window with a specific shape: the array is complete, energised, valuable, attached to the roof, and covered by nothing in particular.
What "covered" actually means once the system is the homeowner's
For an owned, roof-mounted array, most carriers treat the system as part of the dwelling structure. That is the helpful default, and it means the array is covered against the same perils as the roof, under the dwelling limit.
Three qualifications matter enough to check rather than assume.
Mounting type changes the answer. Ground-mounted arrays are frequently not part of the dwelling. They fall under other structures cover, which is typically capped at a fraction of the dwelling limit, or they need scheduling to be covered at all. A ground mount worth a meaningful share of the house can sit inside a limit designed for a fence and a shed.
Batteries are often handled separately again. Storage may be treated as an appliance, as part of the dwelling, or as something requiring an endorsement, depending on the carrier and on how it is installed.
Settlement basis is not the same as coverage. A policy can cover the array and still settle roof-attached equipment on an actual cash value basis, paying depreciated value rather than replacement cost. On a fifteen-year-old array that is a large difference, and it is invisible until a claim.
There is also a limit question that gets missed. A substantial PV solar system raises what it would cost to rebuild the house. If the dwelling limit was not adjusted, the array is nominally covered while the property as a whole is underinsured — and underinsurance can reduce recovery on losses that have nothing to do with the panels.
Third-party-owned systems: insured by the owner, but read the liability side
Under a lease or a power purchase agreement, the provider owns the equipment and insures it. Agreements commonly go further and require the homeowner not to insure the system, so that two policies do not respond to one loss.
This is the cleanest of the arrangements from a property-damage perspective and the one most likely to be misread on liability. Two things repay attention.
The liability allocation — what happens if the array causes damage to the house or injures somebody — is set by the agreement, and it is not automatically the provider's. The host obligations are the other half: notifying the provider of damage promptly, not modifying the system, maintaining access. Failing one of those can move a loss that would otherwise have been the provider's.
It is still worth telling your own carrier that a third-party-owned system is present. The carrier is underwriting a roof that now has equipment attached to it, whoever owns the equipment. The financing structure changes a great deal about post-handover responsibility, which is the theme running through selling a home with solar as well.
The roof claim problem
The single most expensive surprise in this area has nothing to do with whether the panels are covered.
When a covered peril damages the roof under an array, replacing the roof means the array comes off and goes back on. That labour is significant. Whether the policy pays for it depends on whether the carrier treats the removal as a necessary cost of repairing covered property or as work on separate, undamaged equipment.
Carriers differ, policy wording differs, and the outcome is frequently decided by wording rather than principle. The practical move is to ask before there is a claim and keep the answer — and to understand that the detach and reset work has its own cost and responsibility structure regardless of who ends up paying for it, which is what detach and reset sets out. A homeowner who assumed the roof claim would absorb it can find the array is the reason the roof does not get replaced at all.
What good handover looks like
None of this requires anyone in the transaction to give insurance advice, and nobody should. What it requires is that the handoff be treated as a step rather than as an assumption.
- Tell the homeowner when contractor cover ends. Not the policy details — just the date from which the system is theirs to insure.
- Tell them to notify their carrier, in writing, with the installed cost. And to keep the reply.
- Hand over what a claim would need. Equipment list with serial numbers, installed cost, commissioning record, photographs of the finished array. Assembled at closeout this is free. Assembled after a fire it is close to impossible.
- Flag the mounting-type and battery questions if either applies, because those are the cases where the comfortable default answer is wrong.
- Record it. A handover that happened but was not documented is, at the point of dispute, indistinguishable from one that did not.
That list is short, and it is a reasonable share of the difference between a project that is finished and a project that has merely stopped. It belongs in the same place as the rest of the closeout package, and it is the kind of item the project responsibility matrix exists to force a decision on rather than leave implied.
The bottom line
There is no single policy covering a residential PV solar system from delivery to end of life, and there was never meant to be. There are three regimes with two handoffs, and the losses collect at the handoffs — most reliably at completion, when contractor cover ends on energisation and homeowner cover has not been asked to begin.
The remedy is not sophisticated. It is a written notification to a carrier and a documented handover, done at the point when both are trivial rather than at the point when both are urgent.
For sales organisations, the useful reframing is that this sits in the same category as permits, monitoring, and warranty documentation: work that happens after the sale, decides whether the customer has a good year or a bad one, and does not get done unless somebody is accountable for it. Seamless Home takes on that back-end scope — design, permitting, procurement, project management and closeout — so the selling organisation is not choosing between doing it badly and not doing it. Coverage is confirmed per service area rather than promised as blanket availability.

Frequently asked questions
Does homeowners insurance cover solar panels?
Usually yes for a roof-mounted, owned system, because most carriers treat a permanently attached array as part of the dwelling structure rather than as separate personal property — which means it falls under the dwelling limit and the same perils the roof itself is covered against. That general answer hides three important exceptions. Ground-mounted arrays are frequently treated as other structures or as detached equipment and can be capped at a small percentage of the dwelling limit or excluded until specifically scheduled. Battery storage is often handled separately again, sometimes as an appliance and sometimes not at all without an endorsement. And an array large enough to be material to the property's replacement cost can push the dwelling above the policy limit, so the array is nominally covered but the total loss is underinsured. The only reliable way to know is to notify the carrier in writing that the system exists, state its installed cost, and get the coverage position back in writing. A carrier that has never been told about the system has priced the policy without it.
Do solar panels increase your home insurance premium?
Often slightly, and sometimes not at all, because the premium follows the replacement cost of the dwelling rather than the presence of panels as such. Adding a substantial permanently attached asset to a roof raises the amount the carrier would have to pay to rebuild, and premiums track that figure. The increase is typically modest relative to the installed cost of the system, and some carriers make no adjustment for a modest roof-mounted array. What causes larger changes is a coverage limit increase to accommodate the system, an endorsement for a ground mount or battery, or a change in the roof's rating. The more consequential risk is the opposite one: not telling the carrier, saving nothing, and discovering at claim time that the dwelling limit was set for a house without a system on it. Insurers are also increasingly asking about arrays at renewal, so an undisclosed system tends to surface eventually, and it surfaces on worse terms than a voluntary disclosure would have.
Who is responsible if materials are damaged or stolen before installation?
Normally whoever holds title and risk of loss at that moment, which is a contract question rather than an insurance question, and the two do not always line up. Shipping terms determine when risk passes from the supplier to the buyer, and that is often at delivery rather than at installation, so equipment sitting on a driveway or in a garage for two weeks is usually already the installer's or the buying party's risk. The cover that responds is typically inland marine or installation floater cover carried by the contractor rather than the homeowner's policy, which generally excludes property of others and materials awaiting installation. The practical failure is not the absence of cover but the absence of a record: a claim needs proof of what arrived, when, and in what condition, which is why a delivery exception recorded at the moment of receipt is worth more than any argument reconstructed afterwards. The documentation side matters more than the policy wording here, because a claim stands or falls on the record made at receipt.
What is builder's risk cover and when does it end?
Builder's risk, sometimes written as a course-of-construction or installation floater policy, covers the work and the materials during construction against things like fire, theft and weather. It is carried by the contractor or the project owner, not by the homeowner's household policy. The important feature for PV solar is that it is temporary by design and terminates on a defined trigger — commonly the earlier of a stated expiry date, acceptance of the work, or the point at which the installation is put to its intended use. Energising a system is a fairly clear case of putting it to its intended use. So the natural reading is that cover ends somewhere around permission to operate, which is precisely the period when nobody is thinking about insurance because everyone is thinking about the funding milestone. If the homeowner's carrier has not yet been notified, there is a real window in which the array is finished, energised, valuable, and covered by nothing.
Who insures a leased or PPA solar system?
The third-party owner, because it owns the asset and carries the loss if the asset is destroyed. Lease and power purchase agreements normally require the provider to insure the system and normally require the homeowner not to insure it, to avoid two policies responding to one loss and arguing about it. The homeowner's own exposure does not disappear, though, and it is worth reading for two things. The first is liability: if the array causes damage to the house or injures someone, the agreement will allocate that risk, and the allocation is not always what a homeowner would assume. The second is the homeowner's obligations as the site host — notifying the provider of damage promptly, not altering the system, and maintaining access. Failing those can shift a loss that would otherwise have been the provider's. It is also worth telling your own carrier that a third-party-owned system is present even though you are not insuring it, because the carrier is underwriting a roof that now has equipment on it.
Does a roof claim cover removing and reinstalling the panels?
This is one of the most consequential questions on the list and the answer is frequently no, or not fully. When a covered peril damages the roof beneath an array, replacing the roof requires the array to come off and go back on, and that labour can be a substantial share of the total cost. Whether the policy pays for it depends on how the carrier characterises the work: as a necessary cost of repairing covered property, or as work on separate equipment that was not itself damaged. Carriers differ, and the outcome often turns on the specific policy wording rather than on any general principle. Two practical steps help. Ask the question before a claim, in writing, and keep the answer. And understand that the underlying detach and reset work has its own cost and responsibility structure regardless of who pays for it, which is the detach and reset question in its own right. A homeowner who assumed the roof claim would absorb it can find the panels are the reason the roof does not get replaced.
What should a sales organisation tell a homeowner about insurance at handover?
Three specific things, none of which requires giving insurance advice. First, tell them to notify their carrier that the system exists, with the installed cost, and to keep the written response — this is the single highest-value action and almost nobody does it unprompted. Second, tell them when the contractor's cover ends, so they know the date from which the system is theirs to insure rather than discovering it at claim time. Third, hand over the documentation a claim would need: equipment list with serial numbers, installed cost, the commissioning record, and photographs of the completed array. That package costs nothing at closeout and is close to impossible to assemble after a fire. Framing matters here — this is not a disclaimer, it is a genuinely useful handover step, and it is the kind of thing that distinguishes an operation that finishes projects properly from one that stops caring at the funding milestone. It belongs with the rest of the closeout package rather than as an afterthought.
