Commercial solar & battery storage

Electricity is now one of the largest controllable costs on a commercial site, and the only one you can fix for twenty-five years by buying the asset. We design, install and maintain rooftop solar and battery storage for businesses across Sydney, sized from your actual interval data rather than your roof area.

01 · Why now

Four reasons boards are signing these off.

New in 2026: the solar rebate now covers systems up to 1 MW, and the NSW battery discount takes 20 to 40 per cent off business batteries.

01

You stop renting your energy

Every kilowatt-hour you generate is bought once, at install, and used for twenty-five years. Grid rates rise; your self-generated cost does not. For a site with a strong daytime load, that is the whole argument.

02

Batteries attack the other half of the bill

Demand and capacity charges can be a third of a commercial invoice. A battery shaves the peaks that set those charges, shifts cheap midday generation into the evening, and keeps critical load alive through an outage.

03

Rebates and write-offs are still on the table

Federal STCs or LGCs cut the capital cost of the array, and the NSW battery incentive applies to storage. With new incentives being added or changed every week, like the new 1Mw rebate, we guide you through the process, we assess eligibility, model the numbers and lodge the paperwork as part of the job.

04

Emissions reporting is now commercial

Tenders, supply chains and lenders increasingly ask for scope 2 numbers. On-site generation is the simplest, most defensible reduction you can point at, and it appears on the balance sheet as an asset rather than an offset.

02 · Sectors

The case is different in every industry.

What your load looks like across the day decides how much of the array you use and whether storage earns its place.

01 Dealerships & service centres

Showroom lighting, workshop plant and EV chargers, all off your own roof

02 Manufacturing & industrial

Big daytime loads and big roofs, the strongest payback in the market

03 Data centres

A continuous megawatt load, and a visible answer on social licence

04 Warehousing & logistics

Vast unused roof area, refrigeration and forklift charging

05 Retail & shopping centres

Trading-hours load, common-area recovery and tenant billing

06 Offices, commercial property & strata

NABERS ratings, outgoings relief and asset value

07 Healthcare & aged care

24/7 load, backup resilience and heat-wave protection

08 Hospitality

Kitchens, cool rooms and air conditioning on your own generation

09 Education

Weekday load that matches the sun, plus a live teaching asset

10 Agriculture

Irrigation, sheds and pumping, often with weak grid supply

11 Public sector & government

Net-zero commitments delivered against budget

03 · The system

What actually goes on the roof.

We are brand agnostic. Panels, inverters and batteries are selected on warranty, serviceability and local support, not on a distribution deal.

ComponentTypical scaleWhat it delivers
Tier-1 panel array30 kW – 5 MWDaytime generation at a fixed lifetime cost per kWh.
String or central invertersMatched to arrayRedundancy: one fault never takes the whole site offline.
Battery storage50 kWh – 2 MWhPeak demand shaving, evening load shift, backup supply.
Metering & monitoringWhole siteLive generation, consumption and fault alerts you can report from.

Indicative only. Final specification follows the site assessment and interval data review.

04 · Scope of works

One contractor, whole job

Most solar companies install panels and sub-contract the hard parts. Switchboards, protection, supply upgrades and network approvals are our core trade. We have been doing them since 1999.
