Will my home insurance go up if I add solar?

Usually $0-50/year for the average rooftop system. Some carriers do not change premium at all. Battery storage may add another $30-80/year.

What if my carrier does not cover solar?

Rare in Nevada, more common in some California fire zones. You either find a different carrier, add a wraparound DIC policy, or self-insure the gap. I help clients work through this before install.

Does solar void my homeowners coverage on the rest of the house?

No. Solar is treated as part of the dwelling. The rest of your coverage stays intact unless the install was unpermitted or by an unlicensed contractor.

Is a leased solar system covered by my insurance?

No, the leasing company insures the equipment. But your roof and home damage from any leak or fire is still your policy. Confirm the lessor name your carrier needs on file.

Do I need separate insurance for a battery?

Usually no — most carriers cover batteries under dwelling. A few exclude lithium-ion. Ask specifically and get the answer in writing before install.

Will Solar Mess Up My Home Insurance? — Nevada & California

Short answer: solar usually doesn't "mess up" your insurance, but it does require a phone call to your carrier before install. Most carriers in Nevada and California either include rooftop solar under your existing dwelling coverage automatically, or require a small policy adjustment with no premium increase. The risk isn't getting dropped — it's getting under-insured because you didn't update the dwelling replacement cost.

The three things you need to confirm with your carrier

Does adding rooftop solar require a policy endorsement?
Will the system be covered under dwelling coverage (Coverage A) or other structures (Coverage B)?
What's the new total dwelling replacement cost, and is your Coverage A high enough?

That's it. Most calls take 8 minutes. Don't skip them.

Why this matters

If your home replacement cost was $385,000 and you add a $22,000 solar system, your replacement cost is now $407,000. If your Coverage A is still $385,000 and the home burns down, you're $22,000 short on rebuilding the solar. That's the most common gap I see with my clients.

Nevada carrier patterns I've seen

Across the last 30 systems I've installed, here's what carriers have asked for:

Major national carriers (State Farm, Allstate, USAA, Farmers): Typically include solar under dwelling coverage automatically. May require a notification or photo. Premium impact: usually nothing or under $40/year.
Regional and lower-cost carriers: More likely to require an endorsement or a small premium increase. A few will exclude solar from wind/hail unless added separately.
Lloyd's-backed surplus lines: Almost always require explicit notification and may re-rate.

I'm not naming carriers because terms shift constantly. The pattern matters more than the brand.

California specifics

California's wildfire underwriting environment changes the conversation. The Insurance Information Institute tracks the broader market issues. Some carriers in high-fire-risk zones in California have non-renewed policies and the FAIR Plan picked them up. The FAIR Plan covers solar under dwelling but with caps — confirm the cap matches your system value before install.

What carriers actually ask about

Was it installed by a licensed contractor? (Nevada C-2 or California C-46 license)
Was it permitted and inspected by the local AHJ?
Roof-mounted or ground-mounted? (Roof is universally easier to insure.)
Is there a battery? (Some carriers want lithium-ion details.)

A clean install with a licensed contractor and pulled permits answers all four with a yes.

Battery storage triggers more questions

Adding a Tesla Powerwall or Enphase battery is where carriers get particular. A few want the battery declared as separate equipment. A few exclude lithium-ion fires from coverage by default. Always disclose batteries upfront and get the lithium coverage in writing.

A real Henderson example

Client called State Farm before her install. Agent said "no problem, just send us the contract once it's signed." She did. They updated the dwelling replacement cost upward by $19,000 to match the solar value. Premium went up $32/year. Done. That's the typical outcome.

A real Riverside example (CA)

Different client, different outcome. Their carrier had non-renewed everyone in the zip code. They were on FAIR Plan. FAIR Plan covered solar but at $250K dwelling cap; the rebuild cost was $410K. We had to find a wraparound DIC (difference in conditions) policy to cover the gap. It took 3 weeks. The install still happened, but the insurance side took longer than the install.

What to ask your carrier

Is rooftop solar covered under my dwelling coverage automatically?
Do you need an endorsement before install?
What documentation do you need from my installer?
Will my premium change?
What's my new dwelling replacement cost with the system added?
Does coverage extend to the inverter and any battery?
Is wind, hail, and lightning included for the panels?

Red flags from installers

"Don't worry about your insurance, it's covered." Wrong answer. The right answer is "call your carrier, here's the documentation packet they'll want." If your installer can't produce a documentation packet for your insurer, that's a sign they're new to the process.

Common mistakes

Forgetting to update dwelling replacement cost. Assuming a battery is covered when the policy specifically excludes lithium-ion. Letting an unlicensed installer do the work — most carriers exclude unpermitted modifications.

Bottom line

Solar doesn't blow up your insurance. But you have a 10-minute phone call to make before install, and you need to update your dwelling coverage afterward.
