Insurance Considerations for Commercial Solar and Battery Systems

Guide · Commercial solar & battery · ~5 min read

A commercial solar and battery system is a significant asset sitting on your roof and in your switchroom, so it pays to get the insurance side right before it goes in. Here's what business owners and facility managers need to think about to keep coverage solid and claims straightforward.

Why solar and battery changes your insurance picture

Adding a solar array and battery to your premises changes the value and risk profile of the building. The panels, inverters, battery enclosure and associated electrical work are all assets that may need to be declared, and the way they're installed can affect how your insurer views the property.

Most standard commercial property and business insurance policies weren't written with rooftop generation in mind. That doesn't mean you can't be covered, but it does mean you shouldn't assume the system is automatically included under your existing policy.

• The system increases the insurable value of your property
• Roof-mounted equipment introduces new weather and fire considerations
• Battery storage is treated differently to solar alone by some insurers

Talk to your insurer before you install

The simplest way to avoid a nasty surprise at claim time is to speak with your insurer or broker before the work starts. Let them know the type and scale of system you're planning, where the battery will sit, and who's doing the install.

Insurers often want to know the system is being fitted by accredited professionals to recognised standards. Being able to point to a CEC and SAA accredited installer, with the design and compliance documentation to match, generally makes that conversation easier.

• Confirm whether the system is added to your existing policy or needs a separate one
• Ask how the sum insured should be adjusted
• Check any conditions around battery location, ventilation and fire separation

Coverage gaps to watch for

Even where a system is covered, the detail matters. Some policies cover the hardware but not lost revenue if generation stops after an insured event. Others may limit cover for weather damage depending on how the equipment is mounted and rated for your site conditions.

Battery systems can raise their own questions. Fire ratings, enclosure standards and the position of the battery relative to occupied spaces can all influence what an insurer is willing to cover and on what terms. It's worth clarifying these points rather than assuming the worst or the best.

• Business interruption or lost generation after a claim
• Weather, hail and wind damage to roof-mounted equipment
• Fire cover specific to battery storage
• Whether export or energy-arbitrage revenue is considered

How a quality install reduces your risk

The build quality of your system has a direct bearing on risk, and insurers know it. Correct mounting for your roof and local wind region, properly rated cabling, compliant isolation and a well-located battery all reduce the chance of an incident in the first place.

At ATI we install with our own in-house team rather than subcontractors, so the standard of workmanship is consistent from design through to commissioning. That consistency, backed by accreditation and full documentation, gives insurers confidence and gives you a cleaner paper trail if you ever need to lodge a claim.

• Mounting and fixings suited to your roof and wind region
• Compliant electrical work and clear isolation points
• Battery placement that considers fire and ventilation
• Complete commissioning and compliance paperwork on handover

Keep your documentation in order

Good records make insurance simpler at every stage. Keep your design drawings, compliance certificates, commissioning reports and warranty details somewhere easy to find, and share the relevant parts with your insurer.

If anything about your site changes, such as a system expansion or a new tenant, let your insurer know so your cover stays accurate. Keeping the sum insured in step with what's actually on site avoids being underinsured when it counts.

• Electrical compliance and commissioning certificates
• Equipment makes, models and warranty terms
• As-built drawings and photos of the installation
• Records of any later additions or changes

Getting the right cover for your site

Every site is different, and so is every policy. Your tariff, roof, battery configuration and insurer will all shape what cover makes sense, which is why generic advice only gets you so far.

If you're weighing up solar and battery for your premises, a site review is the practical first step. We can scope a system that suits your building and energy use, and give you the documentation you need to have an informed conversation with your insurer.
