Residential Solar Panels
Your home electricity consumption determines the best solar system for you. We analyse your usage patterns, roof suitability, and available space to recommend the best panels and inverters, while planning for your future battery needs.
- System size customized to your usage.
- Panels and inverters selected to suit your roof.
- Designed with future battery storage in mind.
- High-quality equipment built for the Perth climate.
Commercial Solar
Make better use of your roof space with a solar system suited to your business’s electricity needs. Complete Air & Solar assesses your operating hours, power usage, and electrical setup to recommend a system that can help meet part of your daytime electricity demand.
- System sizing based on your operating hours.
- Solar capacity matched to your equipment and power usage.
- Better use of available roof space.
- Solar system performance monitoring.
Solar Battery Storage
A solar battery system stores excess electricity generated during the day for use after sunset. Complete Air & Solar evaluates your current inverter, daily electricity usage, and storage requirements to recommend an appropriate Sigenergy battery storage system.
- Store excess solar electricity for later use
- Use stored energy during evenings and overnight.
- Choose battery capacity based on your energy needs.
- Monitor battery charging, electricity consumption, and storage levels.
Solar Inverters
Solar inverters convert the DC electricity generated by your solar panels into AC electricity to power your home or business. Complete Air & Solar supplies premium options from Fronius and Sigenergy, tailored to your system’s capacity, monitoring preferences, and battery requirements.
- Converts solar energy into household electricity.
- Quality inverter options from leading brands Fronius and Sigenergy.
- Built-in monitoring to track power generation and system efficiency.
- Battery-ready options designed for easy future storage upgrades.
Custom Design
Solar Systems Matched to Your Energy Needs
Achieving peak solar efficiency requires panels, inverters, and battery storage to operate as an integrated system. Rather than providing off-the-shelf component packages, we analyse daily energy consumption patterns, roof orientation, site shading, and future expansion goals to engineer a tailored solar solution for residential and commercial properties.
- System capacity matched precisely to daily energy consumption profiles.
- Strategic panel placement to maximise sunlight capture and mitigate shading.
- Inverter capacity calibrated to handle peak power generation safely and efficiently.
- Scalable designs with immediate or future battery storage integration
Why Invest in Solar for Your Property
A well-designed solar system helps you make better use of the electricity you generate, manage energy costs, and plan for future power needs.
Lower Electricity Costs
Generate electricity during daylight hours to power your property and reduce the amount purchased from the grid. Savings depend on your system size and usage patterns.
Better Use of Solar Energy
Run suitable appliances and equipment during solar generation hours to use more of the power your panels produce instead of exporting it.
Battery Storage Options
Store excess daytime generation for evening use. A correctly sized battery can help reduce grid electricity purchases when your panels aren’t generating.
Smart Energy Monitoring
Track solar generation, electricity consumption, and battery performance through compatible monitoring systems. Identify when you use the most power and adjust your usage accordingly.
Future EV Charging
Plan for solar-compatible EV charging when choosing your inverter and system capacity, helping you accommodate a future electric vehicle without unnecessary equipment changes
Lower Environmental Impact
Generating renewable electricity on-site can reduce the amount of grid electricity your property consumes and help lower associated emissions.

Lorretta Jackson
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!
Leanne O'Leary
Very knowledgeable and helpful. They were also reliable and communicated well so I always knew where my job was at.

FAQS
Solar can substantially reduce your electricity bills by generating power you would otherwise buy from the grid. Your savings depend on the system’s output, your electricity tariff, and how much solar power you use directly. Running appliances such as air conditioning, hot water systems and pool pumps during solar generation hours can help you get more value from your system. We assess your electricity usage and property to estimate generation and potential savings, rather than applying the same savings claim to every customer.
We consider your electricity consumption, when you use power, available roof space, shading and budget. We also look at plans, such as adding a battery, buying an electric vehicle or switching appliances to electricity. The aim is to recommend a system that suits your property and energy needs, with network connection requirements considered as part of the design.
The best choice combines reliable equipment, suitable performance, strong warranty support, and a design that works for your property. We consider panel efficiency, inverter capabilities, monitoring, battery compatibility, and local manufacturer support.
when recommending equipment. Installation quality and system design are just as important as the brand names on the quote. We explain the differences between the options so you can choose confidently.
Quality solar panels can provide useful electricity generation for around 25–30 years, although their output gradually reduces over time.
An inverter will generally need replacing sooner than the panels. Actual equipment life depends on product quality, installation, operating conditions, and maintenance. Product warranties and panel performance warranties cover different things. We explain the warranties applying to the equipment in your quote.
Yes. Solar panels can still generate electricity in cloudy conditions, although output is lower than in strong sunlight. Generation varies with cloud cover, season, shading, and panel orientation. When solar production is below your property’s electricity demand, the balance comes from the grid or a compatible battery if one is installed and has charge available. Solar panels don’t generate electricity at night.
