Polygon Energy is a Canberra electrical contractor (ACT licence 2021893), a NETCC Approved Seller and an SAA-accredited designer, and won NECA’s 2023 Small Business Project of the Year. We design and install commercial solar, battery storage and EV charging for Mitchell businesses.
Mitchell workshops, automotive businesses, trade suppliers, warehouses and showrooms often work with limited roof, parking and electrical capacity. Polygon Energy assesses commercial solar, battery storage and managed EV charging against your operating hours, tariff, property arrangements and planned equipment or fleet growth.
For workshops and warehouses, the right system reflects daytime consumption, usable roof area and export conditions, not roof size alone. Smaller commercial systems may suit constrained sites; eligible 100 kW–1 MW projects require a documented STC-versus-REGO decision.
Storage can reduce selected demand peaks, shift solar generation and manage new electrical loads. Backup for compressors, refrigeration or other essential equipment requires separate power and islanding design.
Mitchell’s service fleets and customer-facing businesses need charging matched to dwell times, site capacity and parking use. Dynamic load management and staged cabling can support growth. Carports are considered where roof constraints make them worthwhile.
The Gungahlin District Strategy forecasts about 9,800 jobs in Mitchell by 2050. Clean Energy Regulator records for postcode 2911 show 806 solar installations totalling 9.296 MW, averaging 11.53 kW. These are cumulative postcode records, not Mitchell business adoption rates.
Evoenergy’s 2025 planning report anticipated a future Mitchell Zone Substation early in the 2029–2034 period, with timing then under development. Network approval remains specific to the property and proposed equipment.
From 1 October 2026, eligible solar systems between 100 kW and 1 MW can create STCs with a fixed five-year deeming period.
We compare STCs with REGOs for each project, because the better option depends on your financial and emissions-reporting goals
The Cheaper Home Batteries Program covers qualifying batteries of 5–100 kWh nominal capacity, with certificates on the first 50 kWh of usable capacity. A battery paired with a 100 kW–1 MW solar system needs project-specific confirmation, which we obtain before quoting
Eligible ACT businesses can get a free assessment and co-funded support of up to
Our case studies show each project’s system size,
the problem we solved and the results.
Examine 12 months of bills, interval data, tariffs and operating requirements
Assess roof or land, switchboards, metering and available supply ahead of the planned Mitchell Zone Substation
Compare solar generation, storage dispatch, charging schedules and network conditions
Review connection approvals, incentives, commercial structure and delivery risks
Set out installation, commissioning, monitoring and handover requirements
Yes, if it is installed on or after 1 October 2026 and meets the scheme rules. 100 kW sits at the lower end of the expanded pathway, so we confirm which rules apply before quoting.
As many as your spare supply capacity allows. We measure current demand and vehicle schedules, and managed charging lets more chargers share the same capacity.
No. The forecast project does not replace address-specific Evoenergy connection assessment.
No. A correctly sized battery can lower selected peaks, but it won’t remove demand charges entirely. The saving depends on its power, usable capacity and control strategy.
Yes, subject to landlord consent, roof rights, lease terms, metering and ownership arrangements.
Only for nominated loads. Compliant backup equipment can keep selected circuits running; motors and machinery may need additional engineering.
Yes, for eligible businesses. Federal STCs and the ACT Sustainable Business Program both apply, and current conditions and approval requirements are checked first.
