How Solar Panels Affect Your Insurance
Solar panels are considered a permanent improvement to your home, similar to a new roof or addition. As such, they increase your home's replacement cost value—which is what insurance companies use to calculate your premiums.
The good news? The increase is typically minimal compared to your annual electricity savings. Most homeowners see premium increases of just $10-25 per year, while saving $100-300+ per month on electricity.
Typical Cost Increase
What to Expect
| System Size | System Value | Annual Premium Increase |
|---|---|---|
| 5 kW (small) | $12,000-$15,000 | $8-$15/year |
| 8 kW (average) | $20,000-$25,000 | $15-$25/year |
| 12 kW (large) | $30,000-$40,000 | $25-$40/year |
| With battery storage | Add $10,000-$20,000 | Add $10-$20/year |
These are rough estimates—actual increases depend on your insurer, location, and current coverage limits. Some insurers don't charge anything extra if you're already well-covered.
Factors That Affect Your Rate
- Current dwelling coverage: If you already have high limits, panels may fit within existing coverage
- System type: Ground-mounted systems may be covered differently than rooftop
- Ownership: Leased panels are typically insured by the solar company, not you
- Location: High-risk areas (hurricanes, hail, wildfires) may see higher increases
- Your insurer: Some are more solar-friendly than others
Coverage Requirements
What Your Policy Should Cover
- Physical damage: Hail, wind, falling trees, fire, vandalism
- Theft: Panels are valuable and occasionally targeted
- Liability: If panels cause damage to property or injury
- Electrical damage: Surge protection and electrical fires
Owned vs. Leased Panels
| Scenario | Who Insures |
|---|---|
| You own the panels (purchased/financed) | Your homeowner's policy |
| PPA or lease | Solar company's policy (verify this!) |
| Loan with lien | Your policy, but lender may have requirements |
Replacement Cost Coverage
Why This Matters
There are two ways insurers value your solar panels:
- Replacement cost: What it would cost to install equivalent new panels today
- Actual cash value (ACV): Original cost minus depreciation
Always get replacement cost coverage. Solar technology improves rapidly—10-year-old panels might cost more to replace with equivalent modern equipment. ACV coverage on panels that have depreciated 30-40% could leave you significantly underinsured.
Coverage Amount
Your dwelling coverage limit should be increased by the full replacement cost of your system. For an average 8 kW system:
- Equipment cost: $16,000-$20,000
- Installation labor: $4,000-$6,000
- Total replacement value: $20,000-$26,000
Potential Insurance Discounts
Some Insurers Offer Solar Discounts
Yes, some insurance companies actually offer discounts for homes with solar panels! The logic: solar panels often come with roof reinforcement, modern electrical systems, and indicate a well-maintained home.
Insurers Known for Solar-Friendly Policies
- State Farm: Generally straightforward solar coverage
- Liberty Mutual: Often includes panels in standard dwelling coverage
- Nationwide: Offers some green energy discounts
- USAA: Good coverage options for members
- Tesla Insurance: If you have Tesla panels/Powerwall (limited availability)
Always shop around—a solar-friendly insurer might save you more than the premium increase you'd pay elsewhere.
Steps to Take
Before Installation
- Call your insurer and tell them you're installing solar
- Get a written quote for the coverage increase
- Ask about replacement cost vs. ACV coverage
- Shop competitors if your insurer's increase seems high
After Installation
- Send your insurer the installation contract with system value
- Provide photos and serial numbers of equipment
- Confirm your dwelling coverage limit was increased
- Keep all documentation in a safe place
If You Have a Claim
- Document damage with photos and video immediately
- Contact both your insurer and installer (warranty may cover some issues)
- Don't attempt repairs yourself—this can void warranties
- Get multiple repair/replacement quotes
