Commercial Solar Perth — SAA-Accredited for Warehouses

For a well-sized commercial system in Perth, payback periods typically fall between 3 and 6 years depending on system size, daytime electricity consumption, Synergy tariff structure, and how much of the generation the business self-consumes. A 70kW system on a Malaga warehouse with $114,000 in annual electricity costs projects to a 4-year payback when sized against the actual NMI-based load profile. Businesses with high daytime consumption, such as cold storage, manufacturing, and logistics operations, typically see the shortest payback periods because they absorb a larger proportion of generated output on-site rather than exporting it.

Synergy DEBS — the Distributed Energy Buyback Scheme — is the WA government-set rate that Synergy customers receive for electricity exported to the grid from eligible solar systems. For commercial operators with significant daytime loads, the DEBS export rate is generally a secondary consideration. The primary financial driver is on-site consumption — every kilowatt-hour your system generates and your business uses directly replaces a unit of grid electricity purchased at your full commercial tariff rate. Sunflare Solar’s commercial proposals model both self-consumption and DEBS export revenue so you have the full picture.

Yes. Federal STCs apply to eligible commercial solar systems with a capacity under 100kW, regardless of which state the system is installed in. The STC discount is applied as an upfront reduction on your Sunflare Solar invoice. For commercial systems of 100kW and above, the LGC scheme applies instead. There is no separate WA state solar rebate — the federal schemes are the primary upfront financial mechanisms available to Perth commercial operators. Sunflare Solar confirms STC or LGC eligibility as part of every commercial assessment.

Yes. The Malaga industrial precinct, Wangara commercial corridor, and Canning Vale manufacturing and logistics operations are active parts of Sunflare Solar’s Perth service area. We also cover Osborne Park, Bibra Lake, Welshpool, Kewdale, Jandakot, Rockingham, Fremantle, and Joondalup. The same SAA-accredited team that assesses your site is the team that completes the installation. We do not use subcontractors in any Perth location.

System size depends entirely on your daytime electricity consumption profile, not your roof space. A facility with a $60,000 to $80,000 annual electricity bill and a 10-hour operating day may suit a 50kW to 70kW system. A facility with $120,000+ in annual costs and a three-phase supply may move into the 100kW bracket, at which point LGCs replace STCs as the applicable federal scheme. Sunflare Solar’s commercial assessment starts with your 12 months of NMI interval data — if you don’t have it, we can help you obtain it from Synergy — and produces a system size recommendation tied to your actual consumption curve, not a generic per-square-metre estimate.
