Start with how your business uses power

We help business owners, facility managers and property stakeholders understand how solar and storage may affect electricity costs, operating resilience and long-term capital planning. Every recommendation is based on site information—not a generic package.

I had my solar and battery, EV charge installed this week, and I’m really happy with the whole experience. The team did a fantastic job – all the wiring was neatly hidden, and the installation looks clean and professional. Jay was great to work with. He was patient, knowledgeable, and took the time to design the best installation layout for my home. The whole job was completed in just two days, and the team cleaned everything up before they left. On top of that, their pricing was very competitive. I highly recommend them to anyone looking for a reliable solar and battery installer.

See the costs and estimated payback

Your proposal shows how much power the system could generate, how much your site could use and which tariff assumptions drive the estimate.

Modelled Payback

Payback is calculated from actual electricity data, tariffs, system output assumptions and installed project cost—not a generic industry promise.

Certificate & Tax Considerations

We identify the applicable STC or LGC pathway for the project. Depreciation and tax treatment should be confirmed with your accountant.

Long-Term Cost Visibility

Compare projected energy savings, maintenance assumptions and finance costs across the expected operating life of the system.

Commercial Solar & Storage Sized for the Site

System capacity is determined using interval meter data, available roof area, structural constraints, switchboard capacity, network export conditions and future business loads.

30kW–100kW Commercial Solar

Suitable for offices, retail, warehouses and light manufacturing with consistent daytime electricity use.

100kW–500kW+ Industrial Solar

Designed for logistics, cold storage, manufacturing and larger facilities requiring detailed grid and engineering coordination.

Commercial Battery Storage

Assess load shifting, peak-demand management, backup requirements and solar self-consumption with clearly defined operating assumptions.

Designed Around Your Industry and Load Profile

Different businesses use energy in different ways. We match system design to operating hours, electrical demand, site constraints and continuity requirements.

Warehousing & Logistics

Use large roof areas to offset lighting, material handling, refrigeration and office loads during operating hours.

Manufacturing & Industrial

Match high daytime demand with solar generation while accounting for machinery loads, harmonics, shutdown planning and protection requirements.

Explore solar for manufacturing sites

Retail & Commercial Property

Reduce common-area electricity costs and support building energy-performance and sustainability objectives.

Agriculture & Processing

Model seasonal pumping, refrigeration, processing and storage loads to identify realistic solar and battery opportunities.

End-to-End Commercial Project Management

From initial data review to commissioning, each stage is documented so your business understands responsibilities, approvals, costs and expected outcomes.

1. Interval Data Analysis

We review available smart-meter interval data, tariffs, demand charges and seasonal consumption patterns.

2. Site & Electrical Assessment

Roof, structure, switchboards, cable routes, protection, access and operational constraints are assessed.

3. Grid & Engineering

We coordinate the applicable DNSP application, export conditions and specialist engineering where required.

4. Installation & Commissioning

Work is planned around business operations, with shutdowns, testing, handover and monitoring requirements clearly defined.

What Your Commercial Energy Proposal Includes

We separate modelling assumptions from confirmed equipment, engineering and installation costs so management, owners and advisers can review the project clearly.

  • Interval data and tariff review
  • Recommended PV and battery capacity
  • Panel, inverter and system configuration
  • Grid application and export-condition scope
  • Estimated annual generation and self-consumption
  • Applicable certificate pathway and assumptions
  • Structural and electrical engineering inclusions
  • Itemised installed price and optional costs
  • Modelled cash flow and payback assumptions
  • Product, performance and workmanship warranties

When does a battery make sense for your business?

Battery value depends on the site load profile, tariff structure, peak demand, outage exposure, operating hours and available solar generation. We model these factors before recommending capacity or backup scope.

  • Peak-demand and load-shifting assessment
  • Solar self-consumption analysis
  • Critical-load and backup-scope definition
  • Inverter and switchboard compatibility review
  • Operating strategy and warranty considerations

Commercial Funding Options

Project funding should be considered alongside the energy model and business cash-flow requirements.

CAPEX Purchase

Direct ownership may provide the strongest lifetime value where the business can fund the asset.

Equipment Finance

Eligible businesses may consider finance or green-loan products from third-party providers, subject to approval and contract terms.

PPA or Structured Options

Long-term power purchase or structured arrangements may be available through specialist third parties. Independent legal and financial advice is recommended.

Commercial-Grade Technology & Australian Support

Equipment is selected according to electrical design, environmental conditions, compatibility, monitoring, warranty support and project requirements—not brand name alone.

Project-Specific Selection

Commercial Solar Support Across VIC & NSW

Delivery arrangements are stated clearly for each market so customers understand who manages design, installation and support.

Victoria

Commercial project planning and installation support across Melbourne and Victorian industrial corridors.

New South Wales

Commercial project planning and installation support across Greater Sydney and suitable regional locations.

Commercial Site Assessment

Send us your site address and a recent electricity bill. We’ll review when your business uses power and what to check on site before recommending a system.

Commercial Project Experience

Review genuine SolarPlus installations using verified project photography, location information and system details. We publish project capacity and scope only after the information has been confirmed.

Commercial Solar & Battery FAQs

We use available interval data, electricity tariffs, daytime demand, roof area, switchboard capacity, grid conditions and future loads. The largest system is not always the strongest financial option.

The applicable STC or LGC pathway depends on installation date, total related site capacity, eligibility and current scheme rules. We confirm the relevant pathway during project assessment.

Timing varies by DNSP, system capacity, export limits, protection requirements and the completeness of the application. We provide a project-specific estimate after reviewing the site and proposed capacity.

Potentially, but written landlord approval, lease term, metering arrangements, roof rights and responsibility for the system must be resolved before proceeding.

We plan access, cable routes and required shutdowns around business operations where practicable. Any shutdown requirements are discussed and scheduled before installation.

Backup depends on the selected equipment, critical loads, switchboard design and operating requirements. Backup scope must be engineered and cannot be assumed from battery capacity alone.

Request a Commercial Energy Audit & Financial Review

Provide a recent electricity bill, business location and contact details. We will review the available information and outline the next steps for interval-data analysis, site assessment and a preliminary commercial proposal.
