Commercial solar
How we approach a commercial site
Every site is different, so the design starts with your usage, your roof and your network's requirements.
Site-specific design
Panel layout, inverter selection and cabling planned around your roof, structure, shading and switchboard.
Network approvals
Larger systems often need distributor approval and may have export limits. We prepare the application and explain any conditions.
Installation planned with you
We agree site access, safety and timing with you so the work fits around your operations.
Storage options
Batteries can be considered where they suit your load profile, tariff and backup needs.
Monitoring and support
Monitoring set up at handover, plus fault-finding and warranty support.

- 4
Install, connect and hand over
Licensed electricians install the system, we complete the connection process, then show your team how to monitor it.
Incentives for businesses
Which incentives can a business use?
Solar systems up to 100 kW may be eligible for small-scale technology certificates (STCs), which usually reduce the upfront price. The federal Cheaper Home Batteries Program also supports eligible small businesses. Larger systems fall under different rules, and we'll explain which apply to your site. For tax treatment, speak to your accountant.

Common questions
What payback will my business get?
It depends on when your site uses power, your tariff and demand charges, your roof and the system size. We don't quote generic payback figures. Your proposal includes a site-specific estimate and lists the assumptions behind it.
Do we need network approval?
Most grid-connected systems need approval from your electricity distributor, and larger systems can be subject to export limits or extra technical studies. We prepare the application and explain any conditions before you commit.
Can you install while we keep operating?
Usually, yes. We plan access, safety and any short power interruptions with you in advance.
Can we add EV charging for staff or fleet vehicles?
Yes. See our EV charging page, or mention it in your enquiry and we'll include it in the assessment.
Is the quote free? Is there any obligation?
Requesting a quote is free and there's no obligation to buy.
What warranties do I get?
Products come with manufacturer warranties, which vary by brand and model and are listed on your quote, along with our workmanship warranty terms. You also have automatic consumer guarantees under the Australian Consumer Law, which a warranty doesn't replace.
Which areas do you service?
Our head office is in Ellenbrook, WA. Enter your postcode in the quote form and we'll confirm whether we can help at your address.
