Commercial Solar & Battery
Government STC Update
Commercial Solar Just Became More Accessible
The Small-scale Renewable Energy Scheme now includes eligible solar PV systems above 100 kW and up to 1 MW, installed from 1 October 2026.
Small-scale Technology Certificates, or STCs, can help reduce upfront installation costs when certificate rights are assigned in exchange for a discount. Eligibility depends on the project, required approvals and any existing or related solar systems.
How Your Business Could Benefit
A New Opportunity for Commercial Solar
Reduce Upfront Investment
STCs can provide an upfront financial benefit rather than requiring businesses to wait for certificates to be generated over time.
More Scope to Invest in Larger Solar
Sites previously constrained around the 100kW threshold can reconsider the optimum system size.
Potential for a Faster Payback
Reduced net project cost combined with electricity savings can improve project economics.
Size Your Solar to Match Your Demand
Rather than designing specifically around the historic 100kW incentive threshold.
Who This Affects
Is Commercial Solar Right for Your Business?
If your site has high daytime electricity consumption, significant roof area or an existing solar system that may be undersized, this change could materially alter the business case for solar.
Warehouses & Distribution Centres
Manufacturing Facilities
Shopping Centres & Retail
Commercial Property Portfolios
Agricultural & Regional Businesses
Schools & Education Facilities
Aged Care & Healthcare
Large Offices & Corporate Facilities
Your Solar System Doesn’t Have to Stop at 100 kW
Size Your Solar Around Your
Business Demand
Old Thinking
"Keep the system around 100 kW to retain STC eligibility."
New Opportunity
"Model the system around the site's actual consumption, available roof area, network capacity and commercial return."
If your business needs more than 100 kW of solar, the expanded scheme creates an opportunity to reassess your options.
We consider electricity usage, available space, existing equipment and network requirements when recommending capacity. STC eligibility and network connection approval are separate requirements—both need to be addressed.
KLUEM can assess multiple system sizes — 100kW, 250kW, 500kW and up to 1MW — to determine which delivers the strongest commercial outcome.

Make More of Your Solar With Battery Storage
Use Solar After Hours
Store surplus daytime generation for evening operations or periods of low solar output.
Manage Peak Demand
A suitably sized and controlled battery may reduce peak grid demand where your tariff includes demand charges.
Plan Backup for Essential Equipment
An appropriate backup configuration can supply selected equipment during an outage. Available power and stored energy determine what can run and for how long.
Our Process
How KLUEM Assesses Your Site
Analyse
Review electricity bills, interval consumption data, roof/site constraints and existing electrical infrastructure.
Model
Model appropriate solar system sizes, energy generation, self-consumption, STC assumptions, electricity savings, project cost and estimated payback.
Deliver
KLUEM manages engineering, approvals, procurement, installation, commissioning and ongoing system support.

Estimate Your Solar STC Value
Estimate STCs for a new solar system in WA. Expansions and sites with existing solar need a tailored assessment.
Enter your site details in Inputs, then select Calculate Estimate.
Your indicative STC Estimate
Assumes a new eligible system with no existing or related solar installations. The value is before fees and any GST adjustment. It is not a quote or confirmation of eligibility. KLUEM can assess your site's eligibility, system costs and potential electricity savings.
Figures are only estimates. KLUEM will model your actual site as part of your free assessment.

Frequently Asked Questions (FAQs)
Questions About Commercial Solar?
The Australian Government has expanded the Small-scale Renewable Energy Scheme to include eligible solar PV systems above 100 kW and up to 1 MW, installed from 1 October 2026. This gives more businesses access to STCs that can help reduce upfront installation costs, subject to the scheme’s eligibility requirements.
No. Eligibility depends on the installation and its relationship to any existing solar, as well as the relevant accreditation, approvals and connection requirements. KLUEM can review your project before making a recommendation.
Small-scale Technology Certificates are tradeable certificates created by eligible renewable energy systems, which can be sold to provide an upfront financial benefit toward the cost of a system.
For eligible solar systems, STCs are based on expected electricity generation over a set period and can help reduce upfront installation costs. LGCs are created over time by accredited renewable power stations, based on the eligible electricity they actually generate.
An eligible expansion may qualify, but the assessment must account for existing and related installations. Support for a qualifying addition applies to the added capacity, not the original system again.
The regulator expects applications to open in mid to late November 2026 for eligible installations from 1 October. Confirm how the timing affects the discount in your project quote.
Not automatically. Eligibility depends on your site's electrical infrastructure, roof or ground space, and the final scheme requirements once confirmed.
Yes. Our assessment starts with your electricity bills and consumption data before we model any system size.
