Do solar panels change home insurance in NZ?

Solar panels become part of the house for insurance once they are installed, and your insurer needs to know they are there. Policies differ. Some include domestic solar as part of the home sum insured after you declare it. Some want the sum insured raised by the install cost. Some ask questions about battery storage. The only reliable answer is the one your insurer gives you in writing before you need a claim.

Do this when the system is commissioned, not after a storm. A claim on undeclared panels is a harder conversation than a five-minute update to the policy. Ask what happens if the panels were not declared, and write down the reply.

What to tell them

Give the insurer the install date, the approximate value, whether there is a battery, and that the work has an Electrical Safety Certificate. You do not need to narrate the brand story. You do need them to confirm the panels are covered for the events your policy already covers, such as storm, fire and impact, on the terms in the wording. Ask them to email that confirmation so the policy file matches the install file.

Ask whether the sum insured should rise. A system in EECA's bands, roughly $8,500 to $20,000 before a battery, is enough money that an old sum insured can sit short. A battery adds more, often in a range of about $5,000 to $15,000.

If you financed the system, the bank may also want the insurer to note their interest. Ask the lender. That is a separate form from telling the insurer the panels exist. Keep the insurer's written confirmation with the certificate so a later claim does not depend on a call-centre note nobody can find.

Leaks, storms and workmanship

A storm that damages panels is an insurance question, subject to the policy excess and exclusions. A leak from a poorly flashed bracket is often a workmanship question for the installer first. Insurers commonly look at whether the damage is an insured event or a defect in how the roof was opened. Keep the workmanship warranty and the certificate so you can point at the right party.

Photograph the finished penetrations and the ceiling underneath at handover. If a stain appears later, those photos show when it started. The warranty guide lists the papers: https://homesolarinstallation.co.nz/blog/solar-warranties-nz/

During the install, the installer's public liability should cover their work on your property. Ask for that before they start, especially if subcontractors are on the roof. Your policy is not their substitute for a dropped tile through a skylight on install day.

Batteries and indoor plant

A battery is electrical plant inside or outside the house. Insurers may ask where it is mounted, whether it is indoors, and whether the install was certificated. Answer from the quote, not from a guess. A cramped cupboard that failed inspection is not a detail to hide.

EECA's position is that a battery is optional and usually lengthens payback. If you do buy one, include it in the same insurance call as the panels. The buying guide is here: https://homesolarinstallation.co.nz/blog/solar-battery-storage-nz/

Shutdown labels matter to firefighters and to you. The certificate and the shutdown note belong with the policy documents. The first-month checklist is when you collect them: https://homesolarinstallation.co.nz/blog/first-month-after-solar-nz/

Uncertified or do-it-yourself work

Ask the insurer how they treat an array installed without an Electrical Safety Certificate, or installed by someone who was not licensed for the connection. Get the answer before you buy a kit. Many claims paths get narrower when the work was not lawful. The DIY guide explains why the connection is licensed work: https://homesolarinstallation.co.nz/blog/diy-solar-panels-nz/

A subscription or leased system may be owned by the provider. Ask whose policy covers storm damage to the gear and whose covers water damage in your ceiling. The free-solar guide is the contract side: https://homesolarinstallation.co.nz/blog/free-solar-panels-nz/

Selling and renewals

At renewal, check the panels are still noted and the sum insured still makes sense if you added a battery or more modules. When you sell, the buyer will ask what the policy situation was. You are not assigning your policy. You are handing them the certificate, warranties and approval so they can insure the house they are buying.

A short call list

Use it once, then file the email the insurer sends back.

• Panels installed on this date, approximate insured value, battery yes or no
• Electrical Safety Certificate held
• Please confirm cover and whether the sum insured should change
• What is excluded around leaks, wear, and gradual damage
• Who to call if a storm damages the array

Coastal houses and the same phone call

Ask what excess applies to a solar claim and whether gradual deterioration, wear, or a leak that developed over months is excluded. Those answers change how you use the workmanship warranty versus the policy. A storm that snaps a rail is a different event from a flashing that has wept since the install.

The insurance call is the same for solar panels on homes in Algies Bay, Arkles Bay, Army Bay, Big Omaha, Coatesville, Dairy Flat, Dome Forest, Dome Valley, Glorit, Gulf Harbour, Hatfields Beach, Helensville, Huapai, Kaukapakapa, Kawau Island, Kumeu, Leigh, Matakana, Muriwai, Omaha, Orewa, Puhoi, Riverhead, Snells Beach, South Head, Waimauku, Warkworth, Wellsford, Bayswater, Belmont, Campbells Bay, Castor Bay, Devonport, Forrest Hill, Hauraki, Milford, Narrow Neck, Stanley Point, Sunnynook and Takapuna. Coastal wind and salt at Muriwai, South Head, Leigh, Army Bay, Hatfields Beach, Gulf Harbour, Orewa and Kawau Island are a reason to ask about storm and corrosion wording. A sheltered roof in Coatesville, Kumeu, Riverhead, Forrest Hill, Sunnynook or Milford still needs the panels on the policy. Takapuna, Devonport and Bayswater houses need the same declaration.

Home Solar Installation NZ can introduce a local partner for a certificated install you can describe to an insurer. The form is free and there is no obligation.
