Commercial & industrial energy · Western Australia
Commercial solar, battery storage, embedded networks and off-grid power for WA businesses: wineries and farms, multi-tenant sites, and operations a long way from the grid. Designed, installed and supported from our West Leederville office.
What we deliver
Whether you want to cut daytime power costs, take the edge off peak demand or get off diesel, we’ll design around how your site actually uses energy.
Rooftop and ground-mounted systems that put your daytime energy use on your own generation.
Commercial battery energy storage (BESS) to shift solar into the evening, trim peak demand and, with a backup-capable design, support selected critical loads during an outage.
Shared solar and metering for apartments, commercial centres and multi-tenant sites, so the benefit reaches every tenant.
Standalone solar and battery systems for farms, lodges, mine sites and telecom, where the grid doesn’t reach or can’t be relied on.
We start with your bills and interval data, then run detailed feasibility studies, a desktop study first and a site study where needed, and model your options before you commit.
Performance monitoring, scheduled servicing and fault response under your service agreement.
Who we work with
Local partners across WA
National Renewable is the company doing the work. We bring the buying power and specialist expertise of a city base, together with an established network of local installation partners across WA. They help on projects and with after-sales maintenance, so you get faster response times and the work stays local.
We share the work with local electricians and make sure there is great after-sales service behind every project.
For example: on a recent commercial project, we worked with the client’s own local electrician. They carried out the upgrades the site needed while we delivered the solar and battery together. We avoided duplicating any scopes or work, and the client got the most efficient delivery.
Embedded networks
In a multi-tenant building, rooftop solar usually only helps the common areas. An embedded network puts the whole site behind one connection, so solar and battery power can be shared with every apartment or tenancy and billed fairly. Subject to regulatory exemptions and approvals.
Off-grid & remote commercial power
Running a generator around the clock is expensive, noisy and one fuel delivery away from trouble. A properly designed solar and battery system can carry much of the load, depending on design and conditions, with the generator kept as backup.

How we work
Send us your bills and interval data. We look at when and how your site uses power.
We inspect your roof, switchboard and site constraints.
A tailored design with options, costs, estimated outcomes and the assumptions behind them.
We manage network applications and installation with minimal disruption to your business.
Commissioning, handover, monitoring and scheduled maintenance. Our 5-year commercial workmanship warranty is extended by a further 5 years when an annual maintenance contract (AMC) is in place for the first 5 years.
Case studies

Winery · Eagle Bay, South West WA
About 258 kW of new solar and about 282 kWh of battery across the main winery, the back shed and Wise Winery House. The main winery site was about 85% self-sufficient in August 2026, from monitoring data.
