A commercial solar system shouldn’t begin with the number of panels that fit on your roof.
It should begin with your energy data.
Polygon Energy designs commercial solar and battery systems for Canberra businesses and organisations based on electricity consumption, operating hours, roof and site conditions, connection capacity and future energy requirements.
From offices and hospitality to health, education and larger commercial facilities, the objective is to design the right energy system for the site and the business behind it.
Commercial properties introduce a different set of considerations.
For businesses with substantial daytime electricity consumption, solar can reduce the amount of electricity purchased from the grid and make productive use of available roof or site space.
The objective is a commercial solar system based on how the site actually consumes energy rather than a standard package.
Commercial batteries can play several different roles within an energy strategy.
For some businesses, when electricity is consumed can matter as much as how much electricity is consumed overall.
A commercial battery may be designed to help manage periods of higher demand, increase the amount of onsite solar consumed by the business or shift electricity use across different tariff periods.
Whether that makes commercial sense depends on interval data, tariff structure, operating patterns, battery capacity and the site’s broader energy objectives.
Battery storage can also be considered where a business has defined continuity requirements.
But battery capacity alone doesn’t determine what will remain operational during an outage.
Usable capacity, inverter output, reserve settings, phase configuration and the loads connected to backup all influence how long and how effectively a battery can support the site.
Polygon Energy can identify the loads that matter to the business and determine whether backup should form part of the system design.
EV charging can introduce significant additional electricity demand to a commercial property.
Whether you’re considering workplace charging, shared tenant charging or future fleet requirements, charging infrastructure should be assessed alongside the site’s solar, battery storage and available electrical capacity.
Large commercial and shared charging projects should consider supply capacity, maximum demand, phase balance and managed charging before equipment is selected.
Canberra’s commercial energy landscape includes very different property and operational requirements.
Commercial energy requirements also vary by precinct.
Polygon Energy’s Canberra commercial solar and battery coverage can extend into dedicated local service pages for areas including:
Depending on project size and eligibility, Canberra commercial projects may have access to federal or ACT support.
The source material states that eligible 100 kW to 1 MW solar systems installed from 1 October 2026 can use a fixed five year STC deeming period under the expanded small scale scheme.
Connection capacity, exports, project eligibility and whether STCs or REGO treatment is appropriate still require project specific assessment.
Eligible ACT businesses may receive a free assessment and action plan, with potential co funded support for qualifying energy or water upgrades and EV charging.
Approval, premises and co contribution requirements apply.
Depending on project size and eligibility, Canberra commercial projects may have access to federal or ACT support.
There isn’t one standard commercial system size. It depends on electricity consumption, operating hours, available roof space, connection capacity, exports and what the business wants the system to achieve.
It depends on the site’s energy profile and objectives. Battery storage may provide value through solar self consumption, tariff management, peak demand management or selected continuity loads.
Potentially. Battery storage can be configured to support demand management, but its value depends on the site’s interval demand, tariffs, operating pattern and system design.
Yes. Solar, battery storage and EV charging can be considered together, with charging demand and available electrical capacity incorporated into the system design.
It can when the system is specifically designed for backup. The loads supported will depend on battery capacity, inverter output, electrical configuration and the circuits included in the backup design.
Potential support depends on the project, system size and current program rules. Eligibility should be confirmed as part of the feasibility and design process.
Every commercial site has a different load profile, property and business case.
Polygon Energy starts there.
