Commercial & Industrial: Energy

Commercial & Industrial Solar & Battery

Solar makes sense for most Queensland warehouses, factories and processing sites — but panels alone only cut costs while the sun’s out and do nothing when the grid fails. HUF Energy Services designs and installs commercial solar and battery systems together — sized to your site’s actual load — so you’re covered on both fronts: lower daytime usage costs from solar, and stored power to offset peak-demand periods and keep critical loads running through an outage.

This is where our industrial electrical background counts. A commercial solar and battery system is only as good as the switchboard integration, protection and backup circuits behind it — engineering work most solar installers aren’t equipped to do properly. We are. For larger installations, we work alongside our RPEQ engineering partner and a network of trusted contractor crews — so the same standard applies whether it’s a single-site system or a larger industrial installation.

Why commercial solar & battery

Cut daytime running costs: solar sized to your site’s load reduces grid usage during operating hours — often your biggest single cost driver.

Cut peak demand costs: store solar and use it during your highest-cost usage periods instead of exporting it for a few cents a kilowatt-hour.

Protect against downtime: keep critical loads running through an outage — production lines, cold storage and refrigeration, server and control rooms.

Properly engineered: SAA-accredited design and install, with switchboard integration and protection handled by licensed industrial electricians.

Right-sized: systems designed around your site’s actual load and usage pattern, not a one-size template.

  • Scales to larger systems: for larger installations requiring RPEQ-certified grid protection and a negotiated network connection, we work with our RPEQ engineering partner on design and sign-off, and can scale our install team with trusted contractor crews for bigger or time-critical projects.

Who this suits

Any site where power costs or downtime are a genuine concern — production and manufacturing facilities, cold storage and refrigeration, and operations where a blackout means lost stock or lost output, not just an inconvenience. Suits sites adding solar for the first time, upgrading an existing system, or adding battery storage to solar that’s already installed — from single-site commercial installs through to larger industrial-scale systems.

Frequently Asked Questions

What size commercial solar or battery system can HUF Energy Services install?

We design and install systems across the full commercial and industrial range — from smaller site upgrades through to larger installations that require RPEQ-certified grid protection and a negotiated network connection with Energex or Ergon. We work with our RPEQ engineering partner on the design and sign-off for larger systems, and bring in trusted contractor crews to scale delivery on bigger projects

Does my system need engineering sign-off?

In Queensland, grid-connected systems of 30kW or above require the grid protection system to be certified by an RPEQ (Registered Professional Engineer Queensland), and typically involve a negotiated connection application rather than standard approval. We manage this process for you, working with our RPEQ partner on the technical design and network application.

How is a commercial system priced?

Commercial and industrial systems are quoted project-by-project after reviewing your load profile, current electricity spend, backup requirements and site conditions. We'll walk through your options and provide a detailed proposal, not a generic per-watt estimate.

How long does a commercial installation take?

Timelines vary with system size and network approval requirements — larger systems needing a negotiated network connection generally take longer to approve than standard connections. We'll give you a realistic project timeline, including design, engineering sign-off, equipment lead times and installation, as part of your proposal.

Are there rebates for commercial solar and battery systems?

Commercial systems under 100kW currently qualify for the same federal STC scheme as residential, applied as an upfront discount. From 1 October 2026 (subject to final regulations), this expands to systems up to 1MW — the government’s own estimate is around a 20% cost reduction for newly-eligible mid-sized systems. We’ll confirm exact eligibility and current incentives as part of your proposal.
