Many Australian businesses face challenges that a solar-for-business setup can solve:
A professionally installed solar system for commercial buildings offsets these issues by generating free, renewable energy during business hours — where it counts most.
A commercial solar panel system uses rooftop-mounted panels to capture solar energy and convert it into electricity via an inverter. This powers your load during the day; excess power can be stored or exported to the grid. System types include:
Our solutions are tailored for high efficiency and seamless integration with your building's electrical systems.
Roof analysis, power usage audit and system sizing.
Engineered layout to maximise yield and savings.
Full compliance with Australian grid and safety standards.
Performed by SAA-accredited electricians.
System commissioned and monitoring enabled.
We make commercial solar installation simple and efficient. The entire process takes 2–4 weeks depending on size and approvals, with minimal disruption to your daily operations.
A Lachlan Solar commercial solar system offers:
The savings start from day one and continue for decades — making solar a strategic financial asset for your business.
We're not just installers — we're long-term energy partners to businesses across Australia. When you choose Lachlan Solar, you get:
A commercial solar system is more than an energy upgrade — it's a business decision that improves profitability, reduces carbon impact and prepares your operation for the future.
Your electricity needs, operating schedule and roof space will determine the ideal system size. A warehouse with large refrigeration needs requires a bigger system than an office using mainly lighting and computers. The best way to size your system is to analyse your past 12 months of bills and match solar generation to your daytime demand.
Savings vary, but many businesses cut their power bills by 40–70% with a well-designed system. The exact figure depends on how much electricity you use during daylight hours and how much solar you consume directly rather than exporting.
For many Australian businesses, solar pays for itself in 3 to 6 years, based on energy prices, system capacity and usage. Since panels last 25 years or more, businesses often enjoy decades of low-cost energy after the system has paid for itself.
Yes. With solar, your business becomes less dependent on the grid and more resilient to price increases. Securing solar production now ensures stable expenses over the long term — particularly crucial for energy-intensive industries.
A standard commercial solar system will shut down during a blackout for safety reasons. To keep operating, you'll need solar combined with a battery and backup inverter, or a generator. Many businesses now pair solar with batteries to keep critical equipment running during outages.
Batteries can make good sense for businesses that stay open into the evening, face high demand charges, or want reliable backup power. They add to the upfront cost but can reduce bills and provide more control — whether they're right depends on how your business uses power and your financial priorities.
Solar systems don't need much maintenance, but they should be inspected regularly for safety and performance. Recommended maintenance includes:
