Solar Panels and Home Insurance: What Changes When You Go Solar

Solar Panels Change Your Insurance Equation

Going solar is a smart financial and environmental move. But most homeowners don't realize that installing solar panels affects their home insurance — sometimes increasing their premium, and always requiring a coverage update.

How Solar Panels Affect Your Coverage

Your Dwelling Coverage Must Increase

Solar panels are permanently attached to your home and become part of the structure. This means they're covered under your dwelling coverage (Coverage A). A typical residential solar installation costs $15,000-$30,000. If you don't increase your dwelling coverage by that amount, you're underinsured.

Example: Your home's replacement cost is $350,000 and you add a $25,000 solar system. Your dwelling coverage should increase to at least $375,000.

Premium Impact

Expect your premium to increase modestly:

• Typical increase: 2-5% of your current premium
• On a $2,500/year policy: $50-$125/year more
• Why: Higher replacement cost (more to rebuild), and solar equipment damage adds claim cost

This is partially offset by the fact that solar panels can make your home more resilient (hardened roof attachment points, in some cases).

What's Covered and What's Not

Covered Under Standard Homeowners

• Storm damage to panels (wind, hail)
• Fire damage to the system
• Falling objects (tree limbs, debris)
• Vandalism to panels
• Lightning strikes to the electrical system

Not Covered (Or Needs Special Attention)

• Mechanical/electrical failure: Standard wear-and-tear or component failure isn't covered by home insurance — that's what your solar warranty handles
• Power surge damage: May need a specific endorsement
• Damage during installation: Builder's risk or the installer's insurance should cover this
• Gradual deterioration: Normal degradation over time isn't an insurable event

Leased vs. Owned Panels

If you lease your solar panels (solar PPA or lease agreement):

• The solar company typically insures the equipment
• Your home insurance still covers your roof and structure
• Verify who's responsible for what in your lease agreement
• Notify your home insurer about the leased system on your roof

If you own your panels:

• You're responsible for insuring them
• They're part of your dwelling coverage
• They're your asset to repair or replace after damage

What to Do When Installing Solar

1. Notify Your Insurance Company

Before installation (or immediately after):

• Tell your insurer about the system
• Provide the system cost and specifications
• Increase your dwelling coverage accordingly
• Ask about any solar-specific endorsements

2. Update Your Home Inventory

Document your solar installation:

• Installation contract and cost
• System specifications (brand, model, size in kW)
• Photos of installed panels
• Warranty documents
• Inverter and battery details (if applicable)

3. Review Your Roof Coverage

Solar installation involves penetrating your roof. Make sure:

• Your roof is in good condition before installation
• The installer's warranty covers any roof leaks caused by installation
• Your home insurance roof coverage hasn't changed

4. Consider an Umbrella Policy

Solar systems (especially with battery storage) add a modest liability risk — electrical fire, equipment malfunction. An umbrella policy provides extra protection.

Battery Storage (Tesla Powerwall, etc.)

Home battery systems add another layer:

• Additional cost to insure: $500-$5,000+ for the battery itself
• Fire risk: Lithium-ion batteries carry a (small) fire risk
• Some insurers are cautious: A few carriers have specific requirements or exclusions for battery storage
• Notify your insurer: Always disclose battery installation

Solar Panel Insurance Discounts

Some forward-thinking carriers offer discounts for solar:

• Green energy discount: 1-5% off for eco-friendly home features
• Reduced grid dependency: Lower risk of power outage-related claims
• Improved home value: Some carriers view solar as a home improvement

These discounts are not universal but worth asking about.

The Bottom Line

Solar panels are a great investment, but they require a simple insurance update. Increase your dwelling coverage by the cost of the system, notify your insurer, document everything, and check your warranty coverage for non-insurable failures. The premium increase is modest compared to the long-term savings from solar energy.
