Where do you want to start?
I have a quote to check
Five lines that tell you most of what you need to know.
I want a battery
How we size one, and how the two rebates work.
I need an EV charger
Order online. One fixed price for a standard install.
It’s for my business
Payback modelled on your real usage data.
What we install
For your home
Rooftop solar for homes
Designed around your roof and your usage, not a package.
Home battery storage
Sized to your evening usage, with federal and NSW incentives assessed for eligibility and shown as separate line items.
Hybrid and off-grid systems
Backup circuits for blackouts, and standalone power where there is no workable grid connection.
EV charging
Home and workplace chargers. Standard installs can be ordered online.
For your business
Commercial solar
For warehouses, factories, shops and farms, modelled on your interval data.
Commercial battery and BESS
For demand charges, export-limited sites and keeping critical loads running.
For the trade
Wholesale supply
Panels, inverters, batteries, mounting hardware and connectors for the trade.
How we work
We look before we quote
Roof, switchboard, phase configuration, and your interval data where it matters.
Approval before deposit
Our standard process is to lodge the network application before you pay a deposit, so your export limit is known rather than assumed.
Every number on its own line
Certificate counts, assumed certificate prices and base pricing are shown separately, so the discount can be checked.
Installed and certified
Licensed electricians and accredited installers do the work. Every job gets a Certificate of Compliance for Electrical Work, with a copy provided to you.
Guides you can skim
Every guide opens with the short answer. Open a section only if you want the working.
How a solar and battery system actually works
kW versus kWh, why 20 kWh a day is not 20 kW of solar, and what stays on in a blackout.
NSW battery rebates: how the two discounts stack
One federal, one state, one install. What each pays, and what changed in 2026.
The solar “rebate” is not a rebate: how your STC discount works
A three-part formula. Learn it once and check any quote in ninety seconds.
Commercial solar payback in NSW: a number that survives the bill
Self-consumption, demand charges and the 99 kW question.
How to size a home battery without guessing
Your evening usage is the input. Not your roof, and not the rebate.
Export limits in NSW: what your network will actually approve
Ausgrid, Endeavour and Essential. Why limits exist, and what to do when you are capped.
Where we work
We install across New South Wales, with most of our work in Greater Sydney. Network rules and roof types differ by area, so each main region has its own page.
Common questions

Across New South Wales, with the majority of work in Greater Sydney. We hold NSW Electrical Contractor Licence 467699C.
Do you do commercial work as well as residential?
Yes.
Roughly speaking, residential work is rooftop solar, home batteries, hybrid systems and EV charging; commercial work is larger rooftop arrays, battery systems for demand management, and supply to the trade.
Can I buy equipment from you without installation?
Yes. We wholesale panels, inverters, batteries, mounting hardware and connectors to licensed trade customers.
I know nothing about solar. Where should I start?
With our guide to how a solar and battery system works.
It covers the difference between kW and kWh, why panel watts and inverter watts are different numbers, why an installer puts 13 kW of panels on a 10 kW inverter, what clipping costs, and what actually stays on in a blackout.
Nothing in it assumes you have bought a system before.
