Commercial Solar Just Became More Affordable for Australian Businesses
The Australian Government has announced a significant expansion of the Small-scale Renewable Energy Scheme (SRES), increasing the eligibility threshold for commercial solar systems from 100kW to 1MW. If implemented as announced, the changes are expected to commence on 1 October 2026, making it easier for many Australian businesses to access upfront financial incentives for larger rooftop solar projects.
For businesses considering commercial solar, this represents one of the most significant policy changes in recent years.
What Has Changed?
Until now, the SRES primarily supported residential installations and smaller commercial systems up to 100kW.
Under the proposed expansion, eligible commercial, industrial, agricultural and community buildings will be able to access the scheme for systems up to 1MW. According to the Federal Government, this is expected to reduce upfront installation costs by around 20%, with some larger projects potentially saving businesses hundreds of thousands of dollars.
The announcement recognises what Energy Minister Chris Bowen described as the “missing middle” in Australia’s renewable energy transition: the vast number of warehouses, factories, office buildings and agricultural facilities with large roof spaces that remain underutilised.
What Does This Mean for WA Businesses?
For businesses across Western Australia, the expanded incentive could significantly improve the financial return on commercial solar investments.
Organisations with larger facilities may now be able to install systems that better match their energy consumption, rather than limiting system size to meet previous incentive thresholds.
Businesses that may benefit include:
- Manufacturing facilities
- Warehouses and distribution centres
- Shopping centres
- Office buildings
- Schools and education facilities
- Agricultural operations
- Healthcare facilities
- Industrial sites
Combined with ongoing electricity price pressures, reducing the upfront cost of larger commercial solar systems may make investment decisions easier for many businesses.
Why Planning Early Matters
Although the expanded scheme is expected to begin in October, commercial solar projects require careful planning well before installation.
Every project typically involves:
- Site inspections
- Energy consumption analysis
- Engineering and system design
- Network applications and approvals
- Equipment procurement
- Installation scheduling
Beginning the planning process early helps ensure your business is well positioned to take advantage of available incentives once they become available.
