Residential · Commercial · Trade supply
Home battery storage
Battery systems sized to your actual evening load, with federal and NSW incentives assessed for eligibility and shown as separate line items.
Hybrid and off-grid systems
Hybrid inverter systems, backup circuits and standalone power for properties without a viable grid connection.
EV charging
Home and workplace charger installation, load management and solar-matched charging.
Commercial solar
Systems for warehouses, manufacturing, retail and agriculture, modelled on your interval data.
Commercial battery and BESS
Peak demand management, export-constrained sites and resilience for commercial premises.
Wholesale supply
Panels, inverters, batteries, mounting hardware and connectors supplied to the trade.
Technical guides
Written for people who want to check the arithmetic rather than take a salesperson's word for it. Every guide carries an issue date, a revision number and its sources, and is updated when the underlying scheme rules change.
Watts, kilowatt-hours, inverters and clipping: how a solar and battery system actually works
Start here. Why 20 kWh a day is not 20 kW of solar, why a 10 kW inverter is given 13 kW of panels, what clipping costs, and what stays on in a blackout.
Battery rebates in NSW: how the federal discount and the PDRS incentive actually stack
Two schemes, two certificate types, one install. The full calculation for both, including what changed on 1 May and 1 July 2026.
The solar “rebate” is not a rebate: how your STC discount is really calculated
The three-variable formula, the zone rating, the shrinking deeming period — and how to audit any quote in ninety seconds.
Commercial solar payback in NSW: modelling it so the number survives contact with the bill
Self-consumption ratio, demand charges, the 99 kW threshold, and the shortcut that makes most proposals optimistic.
How to size a home battery in NSW without guessing
Your evening load is the input, not your roof or your rebate. Where to find it and what to do with it.
Export limits and DNSP connection rules in NSW
Ausgrid, Endeavour and Essential: what they will approve, why limits exist, and what to do when you are constrained.
Higher wattage panels are not automatically cheaper
Panel count drives rail, kits, penetrations and labour. The installed cost-per-watt method, worked through.
Where we work
We install across New South Wales, with most work concentrated in Greater Sydney. Network rules, roof stock and load profiles differ meaningfully by area, so we publish an area page for each of our main service regions.

Common questions
Is Set Energy the same company as Set Solar?
Yes. Set Energy Pty Ltd is the licensed contracting entity that designs, supplies and installs the systems. Set Solar is our retail brand, where pricing, packages and current offers are published. One company, one licence, one point of contact.
Is Set Energy a licensed electrical contractor?
Yes. Set Energy Pty Ltd (ABN 58 621 196 316) holds NSW Electrical Contractor Licence 467699C. Installation work is performed by licensed electricians and accredited installers, and every job is certified with a Certificate of Compliance for Electrical Work.
Where does Set Energy install?
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. It is the same document we use to induct our own new staff, so nothing in it assumes you have bought a system before.
