Solar on the Roof: What Your Policy Thinks of Your Power Plant

By The NMH Agency Team, Licensed Agent

A rooftop solar array is a $15,000 to $40,000 asset bolted to your
most weather-exposed surface, and the households installing them at
record pace almost never make the follow-up call to their insurance
agent. Usually that works out, because the default treatment is
friendlier than people fear. Sometimes it doesn’t, and the difference
lives in a handful of specifics: how the system is owned, where it’s
mounted, and whether anyone ever adjusted the dwelling limit. Here’s the
whole picture, panel to paperwork.

The good default: part of
the house

Rooftop panels owned by you and permanently attached
are generally covered as part of the dwelling under Coverage A, against
the same perils as the roof they sit on: fire, wind, hail, falling
limbs. No special endorsement usually required. Two quiet conditions
hide in that sentence, though.

Condition one: the dwelling limit must grow. Your
Coverage A was sized to rebuild the house; the house now includes a
power plant. If the limit never moved after installation, you’ve diluted
your coverage: fine on a partial claim, short on a total one. The
post-install call to bump Coverage A by the system’s replacement cost is
the single most-skipped step in residential solar, and it typically
costs modestly.

Condition two: mounting location changes the bucket.
Ground-mounted arrays, and panels on detached garages or barns, fall
under other structures (Coverage B), the 10 percent
default that rural properties chronically outgrow (a problem with its
own article in this library). A $30,000 ground mount on a $25,000
Coverage B limit is a gap wearing a green halo. Carports and pergola
arrays: same bucket, same check.

Leased systems and
PPAs: read before you sign

A third or more of residential solar isn’t owned by the homeowner at
all: leases and power-purchase agreements keep ownership with the solar
company. Insurance-wise this flips the defaults. The leased equipment is
primarily the company’s asset to insure, and your lease likely
both promises their coverage and imposes requirements on
yours: minimum liability limits, sometimes naming the company
as an interested party, sometimes making you responsible for damage
categories the company’s policy excludes. These contracts vary wildly,
and the insurance section deserves an actual read, ideally before
signing, since some carriers also have appetites and questions about
leased-system homes. Bring us the contract; translating solar-lease
insurance clauses has become a routine part of our week, and it’s much
better as a pre-signature conversation.

Also in the ownership-structure category: systems financed with liens
function like owned systems with a lender’s interest attached, and the
payoff-versus-claim mechanics are worth one question at claim time.

The specific perils people
ask about

Hail: covered as part of the dwelling (subject to
your wind/hail deductible, which in percentage-deductible states can be
substantial: our deductibles article applies). Panel glass is tougher
than people assume, engineered and tested for hail, and modern arrays
mostly shrug off the storms that shred asphalt shingles above them.
Mostly.

Wind and hurricanes: covered similarly; in
named-storm states the hurricane deductible applies. Attachment quality
is everything physically, another argument for reputable installers and
documented permits, both of which also smooth underwriting.

Fire and electrical: covered, and worth flanking
with prevention: licensed installation, permitted work, and
rapid-shutdown-compliant equipment. Undocumented DIY electrical work is
both a hazard and an underwriting problem.

Batteries: home storage (Powerwalls and kin)
generally rides as part of the dwelling too, and it’s new enough that
carrier questions vary; disclose it, especially garage-wall
installations, and keep the installation paperwork.

The production question: standard policies cover the
equipment, not lost energy production or the export income
while the system’s down. For most homeowners that loss is small; for
large systems with meaningful export income, ask about it rather than
assume.

The post-install
checklist (ten minutes, once)

Tell your carrier the system exists: size, cost, owned or leased,
roof or ground. Bump Coverage A (or B) accordingly. File the paperwork
trifecta where you can find it: permits, installer warranty, and the
interconnection agreement. Photograph the array for your home inventory.
And at each renewal, confirm the system’s still reflected, since
dwelling limits get recalculated by software that doesn’t always know
about your power plant.

Solar’s a good investment that mostly insures easily. The households
that get burned are the ones whose policies never heard the installation
happen. Make the call the week the inspector signs off; it’s the
cheapest kilowatt-hour decision in the whole project.
