Commercial solar installation in Canberra

Canberra is part of the NSW region of the National Electricity Market, but its network tariffs, levies and building rules are the ACT’s own. Evoenergy’s demand tariff, the territory’s feed-in tariff cost and its all-electric rules for new buildings all change what a solar or battery system is worth.

Vitalic delivers commercial and industrial energy systems Australia-wide, bringing solar, battery storage and control into one site assessment.

Commercial solar in Canberra

Canberra at a glance

Network: Evoenergy
STC zone: Zone 3 (1.382)
Solar exposure: 16.8 MJ/m² a day
Output per kW: ~1,347 kWh a year*
Noon sun height: 31° June · 78° December
Strongest month: December

Panels on a low-pitched roof catch the high summer sun well and the low winter sun less, so output follows the seasons.

The weakest month, June, gives 30% of the strongest, December. An all-electric building’s winter heating load meets the weakest solar months.

Evoenergy is the network

The Australian Energy Regulator lists Evoenergy as the main distributor in the ACT, and notes that Essential Energy also serves some ACT customers. Confirm the distributor on the bill. NSW programs do not cross the border: the NSW batteries for businesses incentive is for businesses in NSW and does not apply in Canberra.

The demand window runs on standard time

Sites with a current-transformer meter, which covers connections rated at 100 A or more, default to Evoenergy’s LV TOU kVA demand tariff (101). It charges on the highest half-hour kVA demand between 7am and 5pm on weekdays, with energy priced in three time bands. Evoenergy states every time in Australian Eastern Standard Time with no daylight-saving change, so in summer the demand window is 8am to 6pm by the clock. A battery or load schedule set to local time needs to allow for that.

Every kilowatt-hour carries the feed-in tariff cost

In 2026–27 the cost of the ACT’s large-scale feed-in tariff scheme adds 3.035 cents per kWh to every Evoenergy network energy rate. Solar used on site avoids that amount along with the rest of the energy charge, which is worth including when comparing self-consumption with export.

Connections above 30 kVA are negotiated

Systems of 30 kVA or less connect under Evoenergy’s model standing offer; larger systems receive a non-standard connection agreement. The 2026–27 enquiry fee, including GST, is $1,097.62 for systems up to 200 kVA and $2,497.52 from 200 kVA to 1.5 MVA, plus $2,507.09 to establish the contract. Evoenergy may set a dynamic export limit: in industrial areas with low weekend loads, it may allow little or no export at weekends and on public holidays. Above 200 kVA, interface protection is required, and an exporting system must meet SCADA requirements.

New commercial buildings are all-electric

Since 8 December 2023, new gas network connections have been prevented in the ACT’s residential, commercial and community facility zones, and new buildings covered by the regulation should be designed all-electric. Industrial zones, most of which are in Fyshwick, Hume and Mitchell, are not covered; other excluded zones, such as parks, transport and non-urban zones, will be considered for inclusion in reviews currently scheduled for 2026 and 2030. For a new commercial building, size the solar, battery and connection against the whole electrical load: Canberra Airport averages 59.7 days a year with a minimum at or below 0 °C, so winter heat-pump load arrives when solar output is lowest.

ACT rebates for business sites

The ACT Sustainable Business Program is the territory’s rebate for business sites in commercial or industrial zones: 75 per cent of the cost of gas-to-electric upgrades, up to $10,000, or 50 per cent of electric-to-efficient-electric upgrades, up to $5,000, plus up to $3,000 for an EV charger. Rebates go to sites with electricity bills of no more than $40,000 a year including GST and/or no more than 20 full-time equivalent staff, need pre-approval, and must be in the program’s action plan. The ACT Government’s batteries page says eligible businesses could receive a rebate for upgrades including batteries; solar gets free advice. The Energy Efficiency Improvement Scheme, delivered through Tier 1 electricity retailers to households and small-to-medium businesses, can cover business heat pumps, hot water, lighting and refrigerated cabinets, depending on what the retailer offers, but not solar or batteries. The ACT has no local councils, so there are no council rebates or upgrade agreements.

Approvals for larger systems

Rooftop solar on a commercial building usually needs no development approval in the ACT, with no kilowatt limit, if it stays 1.5 m from side and rear boundaries and meets the height and heritage conditions. It does need building approval on class 2 to 9 buildings, with a licensed building surveyor as certifier, and a system of 200 kW to 1 MW also needs an Access Canberra operating certificate. An external battery is exempt from development approval only up to 50 kW and 0.4 m³ of battery, excluding the inverter and charge controller. The ACT Government has said it will harmonise its emergency backstop’s technical settings with the NSW approach where possible, using CSIP-AUS for systems up to 200 kW, but no start date had been published by October 2026.

Commercial solar in Canberra: common questions

What is the government rebate on a 100 kW solar system in Canberra?

The federal incentive is small-scale technology certificates (STCs), which installers usually take as an upfront discount. For the example postcode 2601 (Canberra, Zone 3), a new 100 kW system installed in 2026 creates 691 STCs (100 kW × 1.382 × 5 years). At the Clean Energy Regulator’s reported spot price of $39.85 that is about $27,500. This is a postcode example, not a site eligibility check. Confirm your own site’s postcode and eligibility. The figure for a 100 kW system falls each year as the scheme approaches its 2030 end.

Who is the electricity distributor in Canberra?

Evoenergy is the main distributor in the ACT. The Australian Energy Regulator notes that Essential Energy also serves some ACT customers, so check the distributor named on your bill.

What STC zone is Canberra in?

Every Canberra postcode, 2600 to 2618 and 2900 to 2914, is Zone 3 under the 2019 zone-ratings instrument, with a rating of 1.382. The Monaro to the south, including Cooma, is Zone 4.

Are there ACT incentives for business energy upgrades?

The ACT Government’s Sustainable Business Program pays 75 per cent of gas-to-electric upgrades up to $10,000, or 50 per cent of electric-to-efficient-electric upgrades up to $5,000, plus up to $3,000 for an EV charger, for business sites in commercial or industrial zones with electricity bills of no more than $40,000 a year including GST and/or no more than 20 full-time equivalent staff. It gives free advice on solar, and the ACT Government’s batteries page says eligible businesses could receive a rebate for upgrades including batteries. The NSW business battery incentive does not apply in the ACT.

Does commercial rooftop solar need approval in Canberra?

Usually not development approval: rooftop panels are exempt if they meet the boundary, height and heritage conditions. Building approval is needed on class 2 to 9 buildings, which include offices, shops, factories and warehouses, and a system of 200 kW to 1 MW also needs an Access Canberra operating certificate.

Can a Canberra business claim certificates on a system larger than 100 kW?

From 1 October 2026, new solar systems above 100 kW and up to 1 MW can create small-scale technology certificates (STCs), with a fixed deeming period to 2030. The Clean Energy Regulator says applications for these systems open in mid to late November 2026, and evidence of network connection approval is required. Only capacity installed on or after 1 October 2026 is eligible, so an extension earns certificates on the added panels only.

* Illustrative. Output is modelled with PVGIS 5.3, EU Joint Research Centre for 1 kW laid flat, 14% system losses and 2005–2023 weather; a real system depends on its roof, shading and equipment. Panels tilted 34° to the north would give the most generation, about 16% more (1,563 kWh per kW), but need frames that usually cost more than the extra output earns. Solar exposure is the Bureau of Meteorology’s long-term station mean. The 100 kW certificate example uses postcode 2601, its statutory zone rating and 5 deeming years, with the count rounded down. The displayed value is floored to $100 at the Clean Energy Regulator’s reported spot price; installers usually take certificates as an upfront discount. A site’s postcode and eligibility require confirmation.
