Solar for Australian businesses
Commercial solar panel installation for your business
Put your commercial roof to work with a solar system designed around your electricity demand and operating hours.
Australian Design Solar helps businesses compare rooftop solar, inverter options and battery storage. From a small commercial premises to a larger warehouse or workshop, we start with how your site uses energy and what you want the project to achieve.
Request a tailored proposal that considers your electricity bills, roof space, electrical infrastructure and installation requirements.
Generate electricity at your workplace
Commercial solar designed around daytime demand
Commercial solar panels generate electricity during daylight hours. Using that electricity on site can reduce the amount your business buys from the grid.
The fit between solar generation and business consumption matters. A site operating throughout the day may use its generation differently from a business with evening shifts, weekend closures or seasonal demand.
We help you explore a system size and equipment configuration with those operating patterns in mind. The goal is a proposal that explains the equipment, installation scope and assumptions behind the recommendation.

Set clear project goals
Why consider solar for your business?
Your priorities help define the project. Tell us whether your focus is daytime electricity purchases, future site changes or a combined solar and battery system.
Offset electricity used on site
Solar can supply part of your daytime demand for lighting, equipment and other business loads. Review consumption patterns to understand how much generation your site may use directly.
Plan around future operations
Discuss planned equipment, longer operating hours or electric vehicle charging before choosing a system. Future changes are useful inputs to the design discussion.
Explore solar with storage
If electricity demand extends beyond solar hours, ask whether a battery merits assessment. Storage should have a clear purpose and be evaluated alongside the solar project.
Compare commercial system sizes
20kW, 30kW and 50kW solar options
System size should follow site demand and suitability. The options below are starting points for assessment, rather than fixed recommendations for a particular business type.
| System option | What to assess | Explore |
|---|---|---|
| 20kW solar | Daytime consumption, available roof area and the electrical setup of a smaller commercial site. | View 20kW solar |
| 30kW solar | A greater generation requirement, the proposed panel layout and how production aligns with operating hours. | View 30kW solar |
| 50kW solar | Higher site consumption, roof and electrical capacity, network conditions and project coordination. | View 50kW solar |
| Custom project | Different capacity requirements, multiple roof areas, existing solar or a combined solar and storage proposal. | Discuss your project |
Solar panel capacity is measured in kW. Electricity generated and consumed is measured in kWh. Actual generation varies with location, weather, season, shading and system design.
Before equipment is selected
What matters in a commercial solar assessment?
A useful assessment brings together energy data, building details and operational requirements. These are the areas to discuss with our team.
Electricity consumption
Recent bills provide a starting point. Where available, interval data gives a clearer picture of when power is used across working days, weekends and different seasons.
Roof condition and layout
Roof age, usable area, shading and access affect the proposal. Discuss any planned roof works and what structural assessment may be required for the project.
Electrical infrastructure
Share known details about switchboards, supply configuration and existing equipment. Ask which electrical checks and potential upgrades are included in the scope.
Ownership and site access
Identify the building owner, site manager and relevant decision-makers early. For leased premises, discuss permissions and the arrangements needed before work proceeds.
Connection requirements
Ask which network approvals and export conditions apply to the proposed system. Confirm who manages each project step and which costs are included.
Business continuity
Tell us about delivery zones, customer access, sensitive equipment and preferred working hours. Identify any electrical shutdown planning needed before scheduling installation.
Understand the complete project cost
How much does commercial solar installation cost?
Commercial solar is quoted according to the selected system and site requirements. Panel capacity alone does not capture the full scope of a business installation.
Equipment models, roof access, mounting arrangements, cable routes, switchboard work and connection requirements can all affect the proposal. Request an itemised quote so you can compare inclusions clearly.
Ask for a clear installation scope
- Panel and inverter makes, models and capacities.
- Proposed roof layout and mounting arrangements.
- Identified electrical work and access requirements.
- Connection, metering and approval responsibilities.
- Monitoring and handover inclusions.
- Any exclusions or provisional costs.
Review the commercial terms
- Total price and the stated GST treatment.
- Payment schedule and quote validity.
- Any incentive assumptions included in pricing.
- Installation scheduling and access arrangements.
- Applicable product and workmanship warranties.
- Support and maintenance arrangements.
If a proposal includes savings or payback estimates, ask for the generation, self-consumption, tariff and cost assumptions. Outcomes depend on your site and operating conditions; a generic promise cannot replace a project assessment.
Different businesses, different energy needs
Discuss solar for your type of premises
Offices and retail premises
Review opening hours, tenancy arrangements and daytime electricity use. Share any restrictions on building access or work around customers and staff.
Warehouses and workshops
Roof area is only one part of the assessment. Machinery loads, shift patterns, deliveries and roof condition help define a practical proposal.
Hospitality and other facilities
Identify daytime and evening demand, refrigeration and equipment priorities. Solar-only and storage options can be discussed against the site’s actual operating pattern.
Commercial solar with battery storage
Give battery storage a clear role in your project
A compatible battery can store surplus solar for later use. For a business, the assessment should start with a specific objective, such as shifting energy to later operating hours or exploring backup for selected loads.
Share your consumption data and ask how the proposed storage capacity, output power and control settings support that objective. Demand-charge management needs a tariff and load-profile assessment.
Backup is a separate design consideration. Confirm supported circuits, power limits and outage operation rather than assuming a battery will keep the entire business running.

- What problem is the battery intended to address?
- How much usable capacity is proposed in kWh?
- What charge and discharge power is available?
- Is it compatible with the solar and electrical setup?
- Is backup included, and for which circuits?
- What warranty and operating conditions apply?

Commercial solar FAQs
Your business solar questions answered
What size commercial solar system does my business need?
The recommendation depends on consumption, operating hours, usable roof area and connection requirements. Recent bills and interval data, where available, help assess suitable capacity. Our 20kW, 30kW and 50kW pages are useful starting points for comparison.
How much does commercial solar cost?
A site-specific quote accounts for equipment, installation access, mounting, electrical work and connection requirements. Request the full scope and total payable amount so you can compare proposals fairly.
Will installation interrupt business operations?
Work areas, access requirements and any electrical shutdowns should be discussed in advance. Tell us about sensitive operations and preferred working times so the installation arrangements can be planned around your site.
Can a business in leased premises enquire about solar?
Yes. Identify the property owner and relevant decision-makers early. Discuss permissions, access and the arrangements required for the proposed installation before accepting a project scope.
Can commercial solar eliminate electricity charges?
A zero bill should not be assumed. Grid imports, supply charges, demand charges where applicable and your tariff structure affect the outcome. Ask any savings estimate to explain its assumptions.
Should my business include a battery?
Storage should address a defined objective and be assessed using your consumption pattern and site requirements. Discuss later operating hours, surplus solar, tariff considerations and any backup priorities before choosing a battery.
Does commercial solar work during a blackout?
A standard grid-connected solar installation normally shuts down during a grid outage. Backup requires suitable equipment and configuration. Ask for supported circuits, output limits and outage behaviour to be specified if this is part of your project.
How long does the project take?
The schedule depends on assessment, approvals, equipment, roof access and the agreed installation scope. Ask our team to confirm the expected stages and timing for your site rather than relying on a generic timeframe.
What should I prepare for a quote?
Have your postcode, electricity bills, business hours and building ownership details available. Share interval usage data, roof information and existing solar details if you have them. Let us know about planned equipment changes.
