Solar for Warehouses & Distribution Centres

Guide · Commercial solar & battery · ~5 min read

Warehouses and distribution centres have two things most sites wish they had: acres of unshaded roof and heavy daytime power use. That combination makes commercial solar one of the more practical upgrades a facility manager can make.

Why warehouses suit solar

Distribution centres tend to run their biggest loads during daylight hours — forklift charging, refrigeration, lighting, conveyors, compressed air and office HVAC. That means a lot of the energy your solar generates gets used on site rather than exported, which is usually where the value sits.

The roof itself is the other advantage. Large, flat or low-pitch spans with few obstructions give you room to scale a system to match your load, anywhere from a modest array up to the multi-hundred-kilowatt range like our 415kW rooftop at DB Santasalo in Bulli.

• High daytime consumption lines up well with solar output
• Big, mostly unshaded roof area to work with
• Predictable operating hours make sizing more accurate

Tackling demand charges, not just usage

For many commercial sites, the bill isn't only about how much energy you use — it's the demand charge tied to your peak draw. Warehouses with simultaneous forklift charging, refrigeration and machinery can spike hard at the wrong moments.

Solar can trim the energy portion of your bill, and when it's paired with a battery you can start managing those peaks too. Reducing your worst-case demand can be significant, though how much depends on your tariff and network — that's exactly what a site review is for.

Where AI energy arbitrage comes in

This is our point of difference. An AI-driven battery charges when power is cheap and discharges or exports when it's dear. For a distribution centre running long hours across shifting tariff periods, that timing can matter as much as the raw generation.

Instead of simply soaking up solar for later, the system reads your tariff and usage patterns and decides the smartest moment to store, use or sell energy back. The result is a battery that works your energy costs actively rather than sitting idle.

• Charge from cheap grid or excess solar
• Discharge to cover expensive peak periods
• Export when it's worth more than storing

Structural and installation considerations

Not every warehouse roof is ready to go as-is. Roof sheet type, age, structural capacity, penetrations and existing switchboard headroom all shape what's practical. Getting this right up front avoids expensive surprises later.

ATI runs an in-house team with no subcontractors, and we're CEC and SAA accredited. That means the crew assessing your roof is the same crew installing and commissioning the system, so accountability doesn't get lost between trades.

• Roof condition and remaining service life
• Structural load and mounting method for your sheet type
• Switchboard and network connection capacity
• Cabling runs across large floor plates and mezzanines

Room to grow and add EVs

Distribution centres rarely stand still. Fleet electrification, extra cold storage or a new automation line can all lift your load over time. Designing with headroom now makes it easier to expand the array or battery later without redoing the groundwork.

If electric vehicles and delivery fleets are on your horizon, factoring in charging early lets your solar and battery share the same infrastructure — rather than bolting on a separate system down the track.

The next step

Every warehouse is different — your tariff, load profile, roof and future plans all change the sums. Real figures come from looking at your actual site and bills, not a generic estimate.

If you manage a warehouse or distribution centre and want to know what your roof could be doing, book a site review with ATI. We'll assess the roof, your consumption and your tariff, and set out what's practical for your operation.
