Turn Unused Roof Space into Energy Savings
A commercial solar system does more than generate electricity. With ever-growing electricity bills, businesses in Perth have started favoring commercial solar systems. A warehouse operating mainly during the day will have different energy requirements from a business running machinery across multiple shifts. At Complete Air & Solar, our team will identify the electricity consumption, operating hours, and electrical infrastructure before deciding on the system size and equipment. This helps us recommend a solar installation that makes practical use of your available roof space and delivers better value over its working life.
Solar Systems Designed for Every Commercial Space
Every commercial property uses electricity differently. A retail store, warehouse or workshop may have different operating hours, equipment loads and peak demand periods. Complete Air & Solar considers these differences when designing a system that makes effective use of solar generation and supports long-term energy savings.
Suitable for:
- Retail stores
- Offices
- Warehouses
- Shopping centres
- Workshops
- Commercial buildings
- Light industrial facilities
We assess your electricity consumption, load profile, available roof space and existing electrical infrastructure to determine a suitable system size. This helps us select compatible equipment, avoid unnecessary capacity, and improve the potential financial return from your solar investment.
Solar Systems Built Around Your Business Energy Needs
Quality solar panels, three-phase inverters and battery options selected to suit your business’s electricity usage
Commercial Solar Panels
We suggest good quality commercial solar panels according to your available roof space, energy needs, and generation. The right panel selection and its layout ensure that your business can produce as much electricity as possible during the working life of your system.
Smart Sizing & Load Profiling
More solar panels don’t always mean greater savings. Excess electricity may be exported at lower rates or restricted by network limits. We review your electricity bills, operating hours, and load profiles to understand when and how much power your business uses. This helps us recommend the right system size, balancing solar generation with actual demand and avoiding unnecessary capacity.
Commercial Three-Phase Inverters
For businesses using three-phase power, inverter selection depends on the site’s electrical capacity, system size, and network connection requirements. We assess the existing supply and any export limits before recommending an inverter suited to your proposed solar installation. This helps ensure the equipment can handle the expected generation while meeting your site’s electrical requirements.
Commercial Battery Storage
Commercial battery storage allows businesses to use surplus solar electricity outside daylight hours or during periods of higher demand. Depending on your tariff and usage patterns, it may also help reduce peak demand charges. We assess your electricity consumption, peak loads, and operating hours to determine whether battery storage offers worthwhile savings now or is better considered as a future upgrade
The Business Advantage of Going Solar
A well-designed commercial solar system helps reduce energy costs, improve efficiency and deliver long-term financial value.
Reduce reliance on the grid:
Produce electricity on-site to reduce grid consumption during the day and reduce your electricity costs.
Improve energy efficiency:
Match solar generation with your business’s daytime electricity demand to make better use of the power produced on-site.
Long-term financial value:
Reduce purchased grid electricity and assess the potential savings and payback from a correctly sized solar system.
Peak demand management:
Properly sized battery storage will reduce peak demand charges, if applicable, to save you electricity costs.
Increased energy control:
Monitor your solar generation and electricity usage with a compatible system to keep track of your electricity costs.

Terrible organization, got quoted 1 prize and the cost on completion was double, no additional work or parts added. Techs were good but I booked for 1 day service and I received 2 different technician even though I booked for the same day service, and 1 week apart
Plan B
Fantastic service from booking to completion of job. System is as good as new.

I had three split systems installed by Complete Air Systems. They were quick, efficient and clean. It was a hard job due to the low roof pitch on my home, but nothing was too much for the team. Happy with thier service and would recommend!
Sorcha Hills
Absolutely 10/10 customer service. I’ve been impressed from initial contact through to going above & beyond to make the final payment easy for me. Highly recommended!

FAQs
Commercial solar can substantially reduce electricity costs, particularly for businesses that use power during daylight hours. Generating electricity on site reduces the amount you need to purchase from the grid. Businesses running air conditioning, refrigeration, machinery or other equipment during the day can be well placed to use that generation directly.
We assess your electricity bills, usage patterns, tariff, and available roof space to estimate the potential savings for your business.
A well-designed commercial solar system can recover its installation cost through electricity savings within several years. The timeframe depends on the system cost, your electricity tariff and how much solar generation your business uses directly. We calculate an estimated payback for your site using your electricity consumption and the proposed system’s expected output. This gives you a practical basis for assessing the investment, with the assumptions clearly explained.
Yes, commercial solar can be installed in stages, provided future expansion is considered in the design. We assess available roof space, electrical capacity, inverter options, and network connection requirements. Planning can make later additions more straightforward and help avoid unnecessary replacement work. Each expansion remains subject to equipment compatibility and any approvals required at the time.
Much of the installation can often be completed while your business continues operating. We plan roof access, deliveries and work areas around your site’s requirements to minimise disruption.
A planned power interruption is generally required for electrical connection work. We agree on the timing with you beforehand and can discuss staged or out-of-hours work where needed.
Yes. We offer ongoing solar inspections, servicing and panel cleaning, including annual maintenance options.
The service frequency and scope are tailored to your equipment and site conditions. Inspections can identify developing faults, check equipment condition, and help investigate reductions in generation. Sites affected by dust, salt exposure, nearby trees or bird activity may benefit from more frequent cleaning and maintenance.
