Does Installing Solar Affect Your Home Insurance?

Solar power has become a valuable part of many South African homes. A well-designed system can reduce dependence on the grid and add substantial equipment to your property — but it can also change what needs to be disclosed and insured.

The important point is simple: installing solar does not automatically mean your home is inadequately insured, but you should tell your broker or insurer and confirm exactly how your policy treats the panels, inverter, batteries and associated equipment.

1. Your solar system can increase the replacement value of your home

Fixed solar installations can represent a significant addition to the property. Depending on the policy and how the system is installed, fixed equipment may be treated as part of the insured building. If the value of the installation is not reflected in the building sum insured, there is a risk that the property may be underinsured.

This is why your broker should know the cost and extent of the installation. Remember that building insurance is generally concerned with replacement or reinstatement cost rather than the market value of the property.

2. Tell your insurer or broker about the installation

A solar installation is a material change to the property and its insured value. Insurers commonly ask clients to notify them when solar panels, inverters, batteries or other backup-power systems are added.

Do not assume the system has automatically been included simply because it is attached to the house. Ask for written confirmation of how it is insured and whether the building sum insured or premium needs to be adjusted.

3. Keep your invoice and Certificate of Compliance

Documentation matters. A reputable installer should provide the relevant installation documentation, and insurers may ask for an invoice, system value and a valid electrical Certificate of Compliance (CoC). Keep these records together with warranties, specifications and installer details.

The exact documentation required varies between insurers, so confirm your policy’s requirements rather than waiting until claim stage.

4. Batteries and inverters deserve special attention

Lithium batteries and modern inverters are high-value components. Their location, installation, ventilation and protection can affect the risk assessment. Some insurers may have specific conditions relating to battery systems or installation standards.

Ask whether batteries and inverters form part of the building cover in your particular setup, whether any limits apply, and whether additional information is required.

5. Understand fire, lightning and power-surge cover

Solar and backup-power systems introduce electrical equipment into the home, so fire, lightning and power-surge exposure should be discussed. Policy wording differs: some policies include certain events automatically, while others have limits, excesses, optional extensions or specific conditions.

The goal is not merely to know that you have “solar cover”. You should understand which insured events are covered and what conditions apply.

6. The roof and installation workmanship still matter

Panels are often fixed directly to the roof, which means installation quality is important. Poor workmanship can contribute to leaks, damaged roofing or structural problems. Insurance policies commonly exclude or restrict losses caused purely by defective workmanship, design or materials, even though resulting damage may be treated differently depending on the wording.

Use a reputable installer and make sure the roof is suitable for the installation before work begins.

7. Theft and weather exposure should be considered

Panels and external components are exposed to weather and may also be targets for theft. Ask how your policy responds to events such as storm damage, hail, theft or attempted theft, and whether security requirements or special excesses apply.

8. If you live in a sectional-title property, check who insures what

If the building is insured through a body corporate or homeowners’ arrangement, do not assume that a privately installed solar system is automatically included in the communal building policy. Confirm responsibility for the system and make sure the relevant insurer has been informed.

A simple solar insurance checklist

Before or shortly after installing solar, give your broker the installation invoice and replacement value, the make and capacity of the panels, inverter and batteries, the installer’s details, the relevant Certificate of Compliance, and any information requested about where the batteries and inverter are installed.

Then ask for confirmation that your building sum insured is adequate, how the solar system is classified under the policy, which excesses and limits apply, and whether there are any special conditions you need to follow.

The bottom line

Solar is a substantial investment in your home. The best time to understand how it is insured is before there is a loss, not after one.
