How does home solar affect my home insurance premiums?

Installing solar panels can impact your home insurance policy, from requiring coverage updates to potentially qualifying for discounts. This guide explains what to discuss with your insurer.

How Solar Panels Interact with Home Insurance

Installing a residential solar energy system is a significant upgrade to your property. Like any major home improvement, it changes your home's value and risk profile, which your home insurance provider needs to know. Generally, solar panels are considered an "attached structure" and should be covered under your dwelling coverage. However, the specifics of how they are installed-whether they are roof-mounted, ground-mounted, or part of a solar shingle system-can affect how you need to adjust your policy. Proactively informing your insurer is a critical first step to ensure you have no coverage gaps.

Key Factors That Influence Your Premium

Several variables determine whether your insurance premium will increase, decrease, or stay the same after a solar installation.

System Ownership: If you own the system outright or are financing it, it is considered part of your home and must be added to your policy. If you are leasing the panels or in a power purchase agreement (PPA), the solar company typically retains ownership and carries its own insurance, but you are still responsible for damage to your roof and may need liability coverage.
Increased Home Value: Solar panels add to your home's replacement cost. Since dwelling coverage should equal this cost, your coverage limit-and thus your premium-may see a modest increase to reflect the new value.
Risk Assessment: Insurers evaluate new risks, such as potential fire hazards from electrical components or damage from wind or hail. Professionally installed systems that meet all electrical and building codes generally mitigate these concerns.
Potential for Discounts: Many insurance companies offer green or eco-friendly discounts for homes with solar panels, often in the range of 5-10%. Some may also offer discounts for homes with newer, more resilient roofs that support the panels.

Questions to Ask Your Insurance Provider

Before your installation is complete, contact your insurance agent with these specific questions.

Do I need to notify you before or after installation? Most companies require prior notification.
How will this change my dwelling coverage amount and premium? Request an updated quote.
Do you offer a green energy or solar panel discount? If so, ask how to qualify.
What is covered under my policy? Clarify coverage for the panels, inverters, and batteries against perils like fire, wind, and hail.
Does my policy include "Inflation Guard" or similar? This can help coverage keep pace with rising replacement costs.
What is my liability coverage if a installer is injured on my property or if the system causes damage to a neighbor's property?

Steps to Take for a Smooth Process

To protect your investment and avoid complications, follow this practical checklist.

Notify Early: Inform your insurer during the planning phase, not after installation.
Review Your Policy: Understand your current coverage limits and deductibles before the conversation.
Gather Documentation: Have your solar contract, system specifications, and proof of professional installation ready to share with your agent.
Consider Umbrella Liability: For larger systems, an umbrella policy can provide extra liability protection beyond your standard home policy limits.
Shop Around: If your current insurer is not solar-friendly or offers significant premium hikes, it may be time to compare quotes from other providers who specialize in or incentivize green homes.

A Note on Location and Installation Quality

Building codes, climate risks like hurricanes or heavy snow, and local regulations vary widely. These factors heavily influence underwriting. Furthermore, the quality of your installation is paramount. Always hire licensed, bonded, and insured contractors who pull proper permits. A poor installation can void warranties and make it difficult to secure insurance.
