Commercial Solar & Battery Systems

Solar for businesses involves more than panels on a roof. Energex connection rules, metering, export limits, and system sizing all need to be worked through properly.

More moving parts than residential

The fundamentals are the same. Solar generates power during the day, battery stores what you don't use, and your electricity bill comes down. But on the commercial side, systems are larger, the Energex network connection rules are different, metering often needs to change, and some sites face export limits. Getting this right from the start matters.

We've been installing solar and batteries since 2010. Our people are qualified electricians, not salespeople. We handle the Energex application and can guide you through the energy retailer side of things. Most installers leave that with you.

  • Lower electricity costs – your solar generation offsets grid consumption during the day
  • Peak demand management – battery storage can reduce demand charges depending on your tariff
  • Price stability – your solar output doesn't change when electricity rates go up
  • Backup power – battery keeps critical systems running during grid outages
  • Scalable systems – sized for your current load, with room to expand if needed
  • Tax incentives – solar and battery may be eligible under instant asset write-off or depreciation schedules. Check with your accountant.

Who we work with

Manufacturing

Daytime production loads line up well with solar generation. Battery can help manage demand spikes. We size systems around your actual load data, not rule-of-thumb assumptions.

Retail and Shopping Centres

Rooftop solar reduces the cost of lighting, refrigeration, and air conditioning during trading hours. Battery adds resilience if power reliability matters to your operation.

Offices

Offices run predictable daytime loads, which suits solar well. We assess whether battery adds enough value for your situation or whether solar alone makes more sense.

Warehouses and Logistics

Large roof areas make warehouses good candidates for solar. We check the structure, work out the available panel count, and confirm what the Energex connection allows before we quote.

How we design a system

Commercial systems need more thought than residential. Your roof space, daily load profile, Energex network connection class, and whether your site can export all affect what system makes sense.

We review your electricity data, assess your roof and switchboard, and work out the right system size for your situation. If a network connection application is required, we handle it. If metering changes are needed, we co-ordinate them.

What we look at

  • Electricity data review – 12 months of consumption patterns, demand peaks, and tariff structure
  • Roof and structural assessment – available space, orientation, and load capacity
  • Shading analysis – obstacles and sun path across the year
  • Energex network connection review – connection class, export limits, and application requirements
  • Metering requirements – smart meter or interval meter changes where needed
  • Equipment selection – panels, inverters, and monitoring suited to the site

Battery Storage and Demand Management

Battery storage works well when your tariff includes demand charges and your peak consumption falls in high-rate windows. In that situation, battery can make a real difference to your bill.

It's not the right answer for every site. We'll tell you honestly whether battery makes financial sense for your situation before we recommend it.

What battery adds

  • Demand charge reduction – discharge during peak tariff windows to lower demand peaks
  • Time-of-use shifting – avoid expensive peak and shoulder rates
  • Backup power – keep critical systems running during outages
  • Grid resilience – keeps essential systems running when the grid goes down
  • Expandable capacity – add storage as your load grows

Monitoring and After-Sales Support

System Monitoring

We set up monitoring at commissioning so you can track production, consumption, and system health through a web dashboard or app. If something isn't performing as expected, you'll be able to see it.

  • Live production and consumption dashboard
  • Mobile app access
  • Performance reporting
  • Fault and underperformance alerts

Scheduled Maintenance

We offer scheduled maintenance to keep your system running as it should. A commercial system is an asset, and it pays to stay on top of it.

  • Annual system health checks
  • Panel cleaning and inspection
  • Inverter testing and firmware updates
  • Call-out support when issues arise

Financing Options

Cash Purchase

Buy outright and own the asset from day one. You get the full benefit of any applicable depreciation or instant asset write-off in the year of purchase. Talk to your accountant about what applies to your situation.

Equipment Finance

Spread the cost over 5 to 10 years. For many businesses, the monthly repayments are less than the reduction in the electricity bill.

Solar Loans

Fixed-rate finance options available for qualifying businesses. Terms vary depending on the lender and your situation.
